shortly thereafter , whitehall securities , in london , came into the picture . simmonds aircraft was formed , with my father contributing the spartan design for 50 % of the equity and whitehall taking the balance for the cash contributed . as your records show , a significant number of aircraft were built and i know the company also built a large number of de havilland gypsy moths under contract .

gatwick became the nineteenth elementary and reserve flying training school in the country . airwork ltd moved in from heston , having been displaced from there due to lack of space . this maintenance company brought with them its contract to maintain whitley bombers for the raf and , along with southern aircraft , became a vital component of the raf ' s maintenance operations in wwii .
in the years since the first aircraft landed on the isle of wight , two isle of wight boat - building companies on the island had started to make aircraft of their own . the first was j samuel white & company , known as white ' s , which had so far specialised in seaplanes , and the other was saunders 1 , which previously had only built flying boat hulls for other aircraft companies .
dominion aircraft ltd based its avro 504 g - aacx at gatwick from november 1928 , but gatwick airport really began life when its new owner ronald waters , who had obtained his first flying license for £1 1s 0d ( 1 guinea ) , had the airfield licensed from 1st august 1930 . flying began that very weekend with pleasure flights for the local population in avro 504s of water ' s surrey aero club .
hello . i came across your post when researching an aircraft my father owned . this is also my first post , so i am hoping that i get a reply . if we are talking about the same aircraft , g - acaf was a spartan three seater which my father bought around 1936 . he kept it at southampton i believe , but used to joy ride it from hayling island . he would have also flew it around the south of england - i shall have to check his log books . the aircraft was badly damaged when he crashed it as a result of an undercarriage leg collapsing . he walked away fortunately . if you have any photos of this aircraft , i would be most interested to see them . i look forward to hearing from you . anthony .

by the end of the 1930s , somerton was used as a private airfield once more , with public services diverting to ryde . during the second world war , the airways were closed and anti - aircraft obstacles were placed on it to prevent germany from using them as landing points for invasion . two of the airports were re - opened , at sandown and bembridge . somerton , however , remained open throughout the war for the use of saunders - roe . three hangars were , unfortunately , destroyed in the raids of 1942 , along with the last spartan aircraft .
in about ' 24 , he was moved to the airworthiness dept . that involved the granting of certificates of airworthiness , to all new civil british aircraft . that job gave my father the opportunity to visit the design offices of all the then uk aircraft manufacturers , of which there were many . this exposed him to all the cutting edge thinking in the aerodynamics of that day .

in 1928 , at the age of 71 , samuel saunders retired . sir alliot verdon - roe , who had been the first man in britain to build his own aircraft and was responsible for the avro aircraft company , took over saunders and renamed it saunders - roe . after this happened , one of the first contracts that came up was one for the blackburn aircraft company . they built 55 bluebird iv aircraft , which were all - metal biplanes . also contracted was the development of the meteor , a twin - engined monoplane , for sir henry segrave 3 . after the prototype was built , sir henry segrave died on lake windemere on 14 june , 1930 , trying to raise the water speed record even further , and so only the prototype and three meteors were ever built .

anthony , if you click on where it says motherbird , the second option allows you to send him a private message which he will receive in his email box . mrs mechta senior was born on hayling island , and mr mechta senior was born in chichester , and was / still is an avid modeller and aircraft enthusiast , so i will ask them if they recall either aircraft when i see them tomorrow .
4 in 1935 , spartan airways merged with united airways , which in 1936 became allied british airways , then british airways , which in 1939 became part of british overseas airways corporation , which later became the british airways we know today .
below is the text of a letter i received in april 2003 from oliver simmonds ' son geoffrey simmonds . this gives a fascinating insight into the background of the simmonds aircraft company . ( reproduced with his kind permission )
saunders - roe continued using the spartan name and built 13 arrows , a small two - seat biplane . they then designed the mailplane , a plane for mail carrying services . only the prototype was built , as it was developed into the cruiser , a passenger - carrying aircraft . 15 of these were built and were sold as far away as yugoslavia , czechoslovakia , egypt and india . the majority of the planes , however , were kept by saunders - roe and were used to start an air - travel company , spartan airways , in 1933 4 . by the end of 1933 it had proved so successful that it became part of southern railways and the railways air services network . you could fly to ryde , isle of wight , as well as to london and birmingham . bembridge airport , isle of wight , was also a regular stop . the last design under the spartan name was the clipper , but only one of those was built .
this picture , sent in by peter lane shows a spartan with a very young peter stood in front of it . it is a possibility that the photo , taken circa 1932 / 33 might have been taken in the bournemouth area ( possibly christchurch ? )
gatwick was sold to the redwing company , whose owner , mr f . bezner , was the manufacturer of a side - by - side two seater aircraft . he moved the redwing flying school in to join the surrey aero club .

during the second world war , all private projects of saunders - roe ceased so that the company could concentrate on the war effort . as a result , saunders - roe spent the war years concentrating on building supermarine aircraft under contract , namely the supermarine walrus 5 and the supermarine sea otter , as supermarine were busy building spitfires . during the war , 461 supermarine walruses were built and 290 sea otters by saunders - roe . even j samuel white & co began to work on aircraft again , building spitfire , mosquito and lancaster parts , although they still concentrated mainly on shipbuilding .
hi has anyone details on prewar avro g - acaf and desoutter g - aane aircraft . where were they flown from ? who owned them ? my father had a flight in one or both while still at school so before 1937 i should think . both photographed in same field . cheers motherbird
on the 28 july , 1919 , j samuel white & company stopped building aircraft and concentrated on building boats once more . white ' s sold the somerton airfield to saunders , who were only just beginning to enter the world of aviation . saunders from then on concentrated on producing its own designs .
gatwick soon grew as a flying club and the aircraft ronald waters owned included an avro 504 , avro avian and a de havilland gipsy moth . by 1931 , the surrey aero club saw an increasing number of jockeys and racegoers arriving by air for meetings at the adjacent race course and a small hangar and clubhouse were built .
the ' beehive ' , the world ' s first circular terminal , was officially opened in 1936 . the beehive had several novel features including a 130 yard long subway to the train station so visitors to the airport could remain undercover from the time they left london victoria until the time they boarded an aircraft . this building still exists outside the southern perimeter and has recently been completely restored .
in 1928 , oliver simmonds started his own company in weston , southampton . he had worked for southampton ' s supermarine company , most famous for building the spitfire . oliver simmond ' s company was known as spartan , and it built club planes and air taxis . building the planes had been sub - contracted to saunders - roe and soon , saunders - roe had a controlling stake in the company , transferring manufacture to east cowes .
the first design for a plane after the war was for the kittiwake , an amphibian flying boat . it was a twin - engined craft capable of carrying up to seven passengers . in 1921 , vickers ltd gained a share in the company , and soon saunders built the valentia flying boat , based on vicker ' s vimy landplane bomber . by 1923 , three valentias had been built , but vickers no longer had a share in the company . saunders started work on building felixstowe f5 flying boats , and flying boats of their own design , including the medina and the valkyrie in 1927 . the valkyrie was the last consuta - built 2 flying boat that saunders built , after which they concentrated on metal - hulled flying boats , starting with the severn .
in 1965 a new joint helicopter development unit ( jhdu ) was formed at old sarum and it immediately absorbed the former hdu , which became a section entitled
short range transport development unit
. in 1963 the 622th ( volunteer ) gliding school became based at old sarum and the school was amalgamated with the amphibious warfare school from poole in dorset to form the joint warfare establishment , being equipped with a few whirlwinds and wessexes . the final change was the amalgamation of army air transport development and the jhdu in 1968 to become the joint air transport establishment ( jate ) . in december 1971 old sarum ceased as an raf airfield , although it served with the army until 1979 . a raf flying club , the bustard flying club was formed in 1957 flying two de havilland tiger moth aircraft . the aircraft were used for flying training , flown by raf instructors .

this plane belonged to my grandfather harold arthur nance - kivell . i believe that in 1932 he was the first man to take air mail from hokittka to okuru via the franz joseph glazier . he along with mr preston and mr stopforth formed west coast airways ltd and the westland aero club . he landed at haast ( in the river bed ) in 1933 and flew over the pass to dunedin a year or two later . there were no landing grounds in those days and he told me that he landed on paddocks , beaches and riverbeds , waiting for low tide so he could make joy rides at westport . from memory when he chatted about those days , he mentioned a story about a badly injured ill man , it was raining too hard and would take forever for a stretcher to go in by foot and bring him to hospital , grandpa flew in very dangerous conditions to collect him . he said it was the only time he was very scared . so in fact he was perhaps the first flying ambulance service .
hello sorry for delay in replying . the photograph of g - acaf was in an old photo album of my fathers . it was taken possibly around 1934 as other photos are of that date . it gives no indication of where it was taken but there are other aircraft on the same field . he writes underneath one of these . my first and perhaps only flight . he was proved to be very wrong on this point as he eventually joined the raf during wwii and flew tiger moths , hurricanes and spitfires as a reconnaissance pilot with 16 168 and 2 squadron ! cheers motherbird . i shall now attempt to post photo of album .
the museum has special tours available on request . one is the “inside lancaster tour” which consists of a personalised tour of the inside and outside of the restored lancaster bomber . the tour takes about an hour to an hour and a half , with detailed descriptions of the mechanics and working of the aeroplane . included is a personal description of each of the crewmembers jobs and positions . this tour is a once in a lifetime opportunity to view first hand the trials and tribulations of being on a lancaster aircraft in ww2 . find out what it is like to crawl over the two wing spars , sit in the wireless operator’s seat and touch the navigator’s desk inside this unique craft . cost is only $ 125 . 00 per person with a maximum of two visitors on each tour . you must book in advance . for an extra $ 50 . 00 you can add a tour inside the dakota c - 47 and spitfire mark xxii .

in 1929 , saunders - roe designed three similar types of flying boat , the cutty sark , cloud , and windhover . all three were monoplane flying boats , and 35 were built . seventeen clouds entered service with the raf , as did a cutty sark . one of the windhovers set a flight endurance record of 54 hours and 13 minutes , flown by a mrs bruce . the next project was the larger london flying boat , which was immensely successful : 31 were built between 1936 and 1938 . it was the london flying boat that was chosen to represent the raf on the 150th anniversary of the founding of the state of new south wales in 1937 . five londons flew across the world to australia , perfectly demonstrating the london ' s long range ability .
one design of flying boat , the a33 , was abandoned after tests with the prototype proved unsuccessful . the next flying boat design was the lerwick . the lerwick was a monoplane development of the london , 21 were built for the raf .
at this time , there were four active airports on the island , at somerton ( cowes ) , ryde , sandown and bembridge . ryde was the busiest airport , which since 1932 had offered sunshine air express services . bembridge was the island base for channel air ferries limited , which offered services to the channel islands and le bourget , france . sandown airport was smaller than the others , but was used by various air services .
shortly before the war began , saunders - roe had started a flying boat project . imperial airways had flying boats on scheduled flights to america , south africa , india , singapore and australia . the flying boats they started off with were c class , later upgraded to the larger g class . saunders - roe anticipated an even larger flying boat , three times the size of the c class , weighing 80 tons . saunders - roe then built a one - third scale flying boat to act as a research vessel . it was soon nicknamed shrimp , but it was larger than both the sea otter and walrus . the research model was finished in the same month in which war broke out with germany and the project had to be put on hold .

my father in 1914 had obtained a scholarship from taunton to magdalene college , cambridge to read history . during his last year at taunton , the rfc landed a plane on the football fields and my father was hooked ! he signed up with the rfc and with a total of less than 20 hrs , went to france and flew fe 2b ' s , a light bomber with two crew . in those days you flew until you were dead or wounded .
upon his entry to cambridge 1n 1919 , he asked if he could use his scholarship to read engineering , rather than history , which was agreed . upon his graduation in 1922 , he joined the rae at farnborough . during his time there , he wrote in conjunction with the only female enginner there , a paper on the effects of supersonic flight on an air foil . as i understand it , ( not being an engineer ) they did that by turning up the speed of the fan in the wind tunnel so that the air flow over the tips of the blades exceeded the speed of sound .

the name gatwick can be dated back to 1241 , when richard de warwick assigned his rights to some land in the manor of charlwood ( four acres of meadow and 18 acres of land ) to john de gatwick and his heirs . the land was part of what was later known as the manor of gatwick and was owned by the de gatwicks until the 14th century when it then passed to various different families .
in 1890 , gatwick was purchased by the gatwick race course company . the race course opened in 1891 , complete with its own railway station .
during the first world war , the aintree grand national was abandoned and a substitute was run over the same distance at gatwick in 1916 , 1917 and 1918 . the winning horses and jockeys for those years were : 1916 - vermouth ridden by j . reardon ; 1917 - ballymacad ridden by e . driscoll and 1918 - poethlyn ridden by e . piggott ( lester piggott ' s grandfather ) .
morris jackaman bought gatwick for £13 , 500 and in 1934 formed airports limited .
jackaman secured the services of marcel desoutter as his business manager . the two later became business partners in 1935 when airports limited was made public - 840 , 000 shares were sold for 5s each and together they formulated plans for a terminal building .
a new railway station was opened at gatwick in september 1935 and was initially served by two southern railway trains an hour , on the victoria to brighton line .
on sunday 17 may 1936 , passengers boarded the first scheduled service from gatwick to paris - the single fare for the flight cost four pounds and five shillings ( equivalent today of £160 . 22 ) and included the first class train fare from victoria .
gatwick ' s ' association ' with the spanish civil war began around this time and makes interesting reading .
during the second world war , the airport was requisitioned by the air ministry for use by the raf , its area was later extended by further requisitioning to include part of gatwick racecourse .
gatwick was retained under requisition and operated for civilian use by the ministry of civil aviation with a small number of charter airlines using the airport .
the government gave approval for the proposed development of gatwick as an alternative to heathrow .
gatwick closed in march 1956 and building began on ' the new london airport ' .
gatwick airport consultative committee , an independent forum of all interested parties concerned with the development and operation of the airport , met for the very first time in 1956 . the committee still plays a pivotal consultative role on airport issues today .
the new gatwick airport was built in two and three - quarter years costing £7 . 8 million .
gatwick was the first airport in the world to combine air , rail and road transport in a close - knit single unit .
the first airline to operate out of gatwick in 1958 was transair and in the first seven months of operating , 186 , 172 passengers used the airport - gatwick now welcomes that many passengers in one busy weekend .
members may read a detailed description of the official opening and the events surrounding it by clicking here .
passenger figures grew to 368 , 000 , still less than a busy week in south terminal today .
work began on enlarging the airport - the terminal was doubled in size and two more piers were built .
since the opening of the terminal still in use today , these are some year by year highlights . . . . . . . . .
passenger figures exceeded 2 million for the first time and the new office block was constructed above the terminal building .
the runway was extended to 9 , 075 feet in 1970 and again in 1973 to 10 , 165 feet ( today it is 3 , 256 metres in length ) .
pier 2 was opened . it was extended in 1984 , providing extra jetty - served stands .
pope john paul ii flew into gatwick on the first papal visit to the uk .
the satellite pier was officially opened by lavinia , duchess of norfolk . the satellite replaced the old north pier and incorporated the first rapid transit system of its kind outside the usa . work also began on building a second terminal . the north terminal was to be the largest single construction project south of london to have taken place in the 1980 ' s - the main building is approximately six times the size of the royal albert hall .
the new air traffic control tower was built and officially opened by princess michael of kent - the tower is still among the tallest in europe .
construction began on the new northern runway , which would be used as alternative to the main runway in case of emergencies .
pier 1 is the only part of the present day south terminal that dates back to the original building in 1958 . a complete modernisation building programme was finished in 1985 to refurbish the pier .
in july 1985 , british airways concorde made its first ever commercial flight from gatwick .
the £200 million north terminal was officially opened by her majesty the queen and the duke of edinburgh .
the new north terminal international departures lounge and the first phase of the new south terminal international departures lounge opened . the investment for both the lounges was £30 million .
baa gatwick launched its ground - breaking sustainable development strategy , which , following three years close consultation with local authorities and communities around gatwick , outlines how the airport should develop during the next ten years .
a £29 . 5m extension to the international department lounge in the south terminal was opened , offering increased seating capacity and new shops and restaurants .
a new extension to the north terminal international departure lounge was opened , a £35m development which offers passengers extra seating and a wider range of shops and catering facilities .
on thursday 27th may 2004 . having been earlier in the week , the new ' air bridge ' is christened by on 27th may 2004 . there is a 2 . 5 meter clearance for a 747 - 400 tail fin .
after many years service with the gatwick airport fire service , hs121 trident 3b g - awzx was finally scrapped .
the new pier 6 air bridge was officially opened on may 16th by alistair darling mp .
the boscombe down aviation collection ( bdac ) tells the history of boscombe down and explains the place it has in the history of flight and air test . in essence the aim is to preserve the past for the future , the same goal as every aeronautical museum . military flying began at boscombe down in 1917 and continues to the present day . experimental operation began in 1940 and the site remains at the forefront for testing as the uk ' s and western europe ' s only dedicated military flight test centre . boscombe down has played a major role in the history of flight and air test . the major aim is to bring this story to life by restorations , construction of replicas and allowing people to experience sitting in some powered cockpits .

old sarum airfield ( icao : egls ) is located 2 nautical miles north northeast of salisbury . the airfield has a caa ordinary licence ( number p768 ) that allows flights for the public transport of passengers or for flying instruction as authorized by the licensee ( blanefield airfield operations ) , but the airfield is not licensed for night use . the site is a mix of residential and industrial sites . residential areas are located to the east , occupying the old airfield quarters and officers ' mess , now known as throgmorton hall . industrial and business units occupy a large number of the original world war i and world war ii airfield buildings , as well as several large modern warehouses , office blocks and car showrooms , a development which is continuing to the present day . old sarum is the best - preserved flying field of the world war i period . it is bounded by one of the most complete suites of technical and hangar buildings of the period .
the site for old sarum airfield was selected in 1917 , to provide facilities for a training station for the rapidly expanding royal flying corps ( rfc ) . like many others of this period , the airfield was provided with a cluster of general service sheds and a camp consisting largely of wooden buildings . it was opened in august 1917 and was briefly known at first as
ford farm
but very soon instead took the name of the much more distinguished local fortifications . its first task was to act as a base for the formation of three new day - bomber squadrons which ultimately would be sent across the english channel to operate in france . the royal air force ( raf ) was founded on april 1st , 1918 by the amalgamation of the royal flying corps and royal naval air service . on the same day a new flying training unit was formed at old sarum to become the airfield ' s principal resident unit . this was the 11 training depot station , which task was the operational training of fresh aircrews .

i sort of went ‘all in’ on an auction for a berkeley interstate cadet this week . in 30 hours , we will see if i won it or not . before this auction , i had no idea this kit existed in the berkeley line . do you know where i can find a complete listing of the 35 inch scale ff berkeley kits ?
bob : thanks so much for your berkeley blog . it really touched a nerve when i first read it . in fact , your blog launched a renewed interest in me for revisiting the 35 inch span free flight civilian aircraft line from berkeley .

i’m just getting back into the hobby after a long absence and i’d never heard of berkeley before . i’ve been cruising through the balsa kits on ebay and mostly been checking out guillows , comet and sterling . i also found a nice selection of berkeley . you’re not kidding when you say they command a premium price .
at the art department : prophecies we are exploring how artistic approaches to the future can impact the world around us . this week we are very pleased to present professor of psychology etzel cardeña on how literature can open up different models of thinking about time . these models of time are brought to life by clips from the spectacular films of the one - and - only director and choreographer – busby berkeley .
the number of berkeley kits being listed on e - bay now are very few in number . the same applies to mccoy motors which i also collect . rl .

i have collected berkeley kits for about fifteen years . what wonderful kits they are . i bought a berkeley b - 25 on e - bay in december 2009 . i paid $ 325 . 00 and thought that was a reasonable price . later i paid about the same price for a b - 26 invader , also on e - bay .
both testing and training auc values had high discriminatory power for im were excellent for 255 models , good for 72 models , fair for 35 models , poor for 8 , and failed for 0 . for the em auc values were excellent for 511 models , good for 156 models , fair for 60 models , poor for 10 , and failed for 3 . when averaged across decades auc test values were excellent for 22 , good for eight , and fair for seven species . for auc train values were excellent for 28 , good for eight , and fair for one species . the internal and external validations suggest that the im and em models are similarly parameterized and well calibrated ( s2 table ) . both of the transferability indices generally provide similar results and suggest that the models are highly transferable ( s2 table ) . the rrs statistic found that many models had values close to 0 indicating strong agreement between the im and em , however there were a number of models that suffered from over - and under - prediction ( s2 table ) . while under - prediction was more common than over - prediction , the magnitude of over - prediction was larger ( s2 table ) . the oi statistic revealed that for many models there was high - predicted overlap between the im and em models , although there were some exceptions ( s2 table ) . while most of the metrics suggest that the models are accurate , well fit , and transferable , there are some em that either over or under - predicted the im , as well as some em that had low overlap with the im , suggesting that these discrepancies arise either as an artifact of modeling , or that some other factor potentially related to life history characteristics affects model prediction and transferability .
the original kit was designed by paul delgatto for berkeley ' s in 1955 . we have recreated the classic model by laser cutting all of the original die - cut parts .

enms can become erratic when transferring projections in space and time [ 6 , 10 ] . while this study used internal and external validations to ensure that models were well parameterized , accurate , and transferable , some models suffered from over - or under - prediction . over - prediction could emerge as an artifact of thresholding , or as a by - product of model parameterization . if a particular threshold was always more lenient ( lower ) than other thresholding approaches than ranges would always tend towards over - prediction , however this was not the case . if the models were over - parameterized then the expectation is that the transferred models would under - predict the range , while the converse is true for under - parameterized models . in some studies , maxent has been known to remove too many variables , resulting in over - predicted range sizes due to under - fit models [ 16 ] . here the high degree of over - prediction for some species suggests under - fitting , although the fit statistics indicate that the models are well parameterized .
bob , came accross your website today ( saturday 4 - 23 - 2011 ) i can relate to the old berkeley’s , as i’m in my late sixty’s . 1st berkeley was the culver v . over the years , i have collected the berkeley kits of which i now have close to 50 or so . along with others ( sterling , sig , comet , cleveland , etc . ) you are correct that the value has gone skyhigh on these kits . i guess when the lord takes me , i will build them up stairs . take care , steve douglas , charlotte , nc
the first two train lines arrived in the city the 1870s , said phil gale , mechanical engineer and treasurer for the berkeley historical society . the berkeley branch line , which later became southern pacific ( sp ) , ran from what is now emeryville to downtown berkeley , and was later extended to vine street . the other early line was a union pacific train that ran from 3 rd street to delaware street . shortly after , the first street railroad was built on telegraph avenue . in the following years additional lines were added elsewhere and companies began to electrify their lines around the turn of the century .

all of these contests related to either gliders or rubber models , because mr . hurst felt that the gasoline powered model was dangerous , and he resisted it .
i had two of the carved fuselage control line models , a p - 51 and a p - 38 , both christmas gifts , but never got up the courage to try flying them even though i was by then pretty good with something like a ringmaster . i built a whole series of the 1 / 2a free flight models and tried to fly most of them without really knowing what i was doing . a few years later when i was a bit more grown up and a whole lot more skilled at model building , the quality of the entire berkeley line suffered from the use of really bad balsa as a cost control measure and before anyone really noticed , they were gone . these days you won’t find the name berkeley on a hobby shop shelf anywhere , and most modelers have never heard of them . there is one balsa wood model airplane kit now on the market that can be traced back to the berkeley lines…do any of you know what it is ?

“i’ve been really interested in the local history and the amazing public transportation system that berkeley had , ” he said . “a lot of it has been replaced by more modern systems , but not necessarily better systems . ”
in the early 60s i built a lot of ff scale models . somehow in the workshop there had always been a kit , berkeley b - 17 flying fortress , which challenged my imagination . i remember carving the fuselage for nearly a year , listening to tv and movies about the plane . i read every book and magazine , and went to airshows to enjoy the sight and rumble .
one day the school principal asked me to show him my models . he asked me to bring the models over and we flew them in the school auditorium . he was quite impressed , and told me that i could fly my models there any time . all i had to do was just ask the janitor to let me in . however , that didn’t work so great because the janitor always seemed to want to hide when i came around , as he was always in a hurry to do something else .

a primary assumption of environmental niche models ( enms ) is that models are both accurate and transferable across geography or time ; however , recent work has shown that models may be accurate but not highly transferable . while some of this is due to modeling technique , individual species ecologies may also underlie this phenomenon . life history traits certainly influence the accuracy of predictive enms , but their impact on model transferability is less understood . this study investigated how life history traits influence the predictive accuracy and transferability of enms using historically calibrated models for birds . in this study i used historical occurrence and climate data ( 1950 - 1990s ) to build models for a sample of birds , and then projected them forward to the ‘future’ ( 1960 - 1990s ) . the models were then validated against models generated from occurrence data at that ‘future’ time . internal and external validation metrics , as well as metrics assessing transferability , and generalized linear models were used to identify life history traits that were significant predictors of accuracy and transferability . this study found that the predictive ability of enms differs with regard to life history characteristics such as range , migration , and habitat , and that the rarity versus commonness of a species affects the predicted stability and overlap and hence the transferability of projected models . projected enms with both high accuracy and transferability scores , still sometimes suffered from over - or under - predicted species ranges . life history traits certainly influenced the accuracy of predictive enms for birds , but while aspects of geographic range impact model transferability , the mechanisms underlying this are less understood .

converse to results from mcpherson and jetz [ 5 ] , this study found that the models for temperate migrants tended to have lower accuracy than those for neotropical migrants or resident species . different studies have come to different conclusions regarding how well models capture the distributions of migrant versus resident birds [ 63 , 72 ] , suggesting that this may vary across geographies and assemblages .
although it has been suggested that collinear predictors do not affect maxent model building , but instead impact model interpretation [ 73 , 74 ] , the inclusion of variables that are collinear can lead to over - fit models and potentially to the elimination of biologically relevant variables [ 40 ] . these models are expected to under - predict the range [ 51 ] , and indeed , this accords with findings from braunisch [ 47 ] in which complex models ( retaining highly collinear predictor variables ) performed better than simpler models ( retaining independent variables ) , despite potential over - fit and under - prediction . although we did observe examples of under - prediction in this study , it was of small magnitude , suggesting that collinearity is not driving the results .

for birds , some of the life history traits that have been examined with regard to enm performance include range size , conservation status , migratory behavior , rarity , endemism , body mass ( size ) , habitat structure , and wetland affinity ( reviewed in mcpherson and jetz [ 5 ] ) . of these traits , range size , migratory behavior , and wetland affinity have detectable impacts on model performance for south african bird species . narrow ranged species models performed better than those for common species , non - migrant species models were better than those for migrants , models for endemics outperformed models for non - endemics , non - wetland species models outperformed wetland species models [ 5 ] . however , the characteristics that contribute to a successful interpolative model ( e . g . a model built and projected within the same climatic and geographic environment ) , may not be the same as those that make for a successful extrapolative model ( e . g . a model built using one climatic and geographic environment and then projected to a different climatic or geographic environment ) [ 6 ] . therefore , transferability as it relates to life - history characteristics should ideally be evaluated explicitly .

this series invites an array of grammar types useful both as learning devices and as research tools . the freedom to break away from latin and greek grammar models , traditionally required , in particular of indo - european historical languages , is respected and even urged when appropriate . on the other hand , the valuable genetic study of language should remain a sought - after , well - developed endeavor , and should not be lost to the present and future world of learning . accordingly , the berkeley models of grammars series seeks forward - looking , theoretically sophisticated methodologies which are at the same time relatively exhaustive or complete grammars of a given language at any period of its existence .

since there are recent studies investigating model variation with regards to geographic transferability [ 37 ] and temporal transferability [ 11 ] and both have found strong support for high transferability of maxent models , i used maxent 3 . 2e [ 38 , 39 ] to build models and then project them into the “future” . enms using matched decadal occurrence records and climate data were generated for each decade , then projected forward in time , such that enms generated using 1950s occurrence points and 1950s climate , were projected to 1960s , 1970s , 1980s , and 1990s climates ( fig 1 ) . interpolative models ( im ) , are developed using occurrence data from a particular decade in conjunction with historical climate data from the same decade , and are expected to be good representations of the species’ distribution [ 14 ] . the extrapolative models ( em ) , which are the interpolative models projected onto a ‘future’ climate are more prone to error because they are built using climate data that differs from the climate to which they are projected [ 16 ] .
interesting to hear the name of berkeley kits . in the 60’s my uncle was briefly partners in a hobby shop . when it closed he gave my dad a berkeley models “b26 invader” model kit with 87 1 / 2 inch wingspan . its huge ! the kit was half built . a guy contacted wanting to “borrow” it . he let the guy take the plans with him only to find out he left a false phone number ! my uncle did not know the guy either so the plans were gone . i still have the kit and someday hope to figure out the proper locations for the fuselage bulkheads . the wings are built . to date i haven’t found anyone who has ever heard of the kit let alone has a plans set .

to gauge model transferability i examine the magnitude of over - or under - prediction and assess the overlap between modeled ranges . this approach assumes that the im better represents the true distribution than does the em [ 16 , 68 ] . external model evaluation was performed using two auc - based transferability indices to gauge the accuracy of the extrapolative models . both ti h ( ti h = auc ( em ) / auc ( im ) ) , developed by heikkinen et al . [ 37 ] and ti w ( ti w = ( 1 - ( auc diff ( em ) ) ) / ( 1 - ( auc diff ( im ) ) ) developed here , are simple ratios in which values less than one indicate that the interpolative models are providing more accurate predictions than the extrapolative models . values close to one are indicate equivalent accuracy of interpolative and extrapolative models . the second index , ti w differs from ti h by incorporating the internal evaluation into the ratio . i also use metrics to quantify mismatch between the interpolative models ( im ) and the extrapolative models ( em ) . the metrics used here are from [ 69 ] and include the relative range size ( rrs ) and the overlap index ( oi ) . they are intended to provide insight into the performance of the transferred extrapolative models ( em ) relative to the interpolative models ( im ) . the relative range size ( rrs ) ( if im < em rrs = em / im - 1 , else rrs = - 1 ( im / em - 1 ) is a measure of the over - or under - prediction of suitable area of the em relative to the im . a positive number means that the em over - predicts the range , a negative value means it under - predicts the range , and a value close to 0 indicates model similarity [ 16 ] . the overlap index ( oi ) ( oi = ( o / im ) ) quantifies agreement between the predicted and projected species range . oi records the amount of congruence between the im and em models . it is a simple ratio that quantifies the overlap between the im and em models with respect to the im . values range from zero to one . a value close to one indicates that the em performs well in predicting the species range . a low value indicates little agreement between the models .
the performance of enms built using historical climate and occurrence data varied in their ability to predict “future” species distributions . in this study models were projected to highly similar analogous environments , under the expectation that they should transfer well [ 61 ] . the testing auc scores for the models were overall quite high , and the models were well calibrated with only a slight tendency toward over - parameterization ( which is less problematic than under - parameterization [ 52 ] ) . although the transferability scores were generally high , the transferability of the models varied . while the glms did not find any of the life history traits to be significant predictors of transferability as measured by ti h or ti w , the oi statistic suggests that commonality versus rarity of species across their distributional ranges may play an important role in the predictive ability of extrapolated models . in this study , this was the only life history character that significantly predicted overlap . in contrast , the wilcoxon test suggests that there are statistically significant differences in transferability for narrow versus widespread species , but not for common versus rare species .

for range , widespread versus narrow species distributions but not the commonness or rarity of the species impacted the model accuracy , with narrowly distributed species having higher model accuracy than widespread species ( fig 2 ) . to determine if this finding reflects an artifact of modeling or an effect of life history trait , auc scores for models for narrowly distributed species were re - evaluated with a reduced background extent and then compared to models with the full background extent . the two sets of models were found to be statistically significantly different ( auc test : t = 5 . 4379 , p - value = 0 . 000 ) which suggests that these differences arose as an artifact of modeling .

many studies examining the impact of life history traits have recovered a pattern whereby models for narrow ranging , endemic species have higher model accuracy than those for widespread species as assessed by auc scores [ 5 , 10 , 63 , 64 ] . however , for species occupying a restricted range relative to the extent of the background area modeled , auc scores can be elevated as an artifact of modeling due to sampling prevalence and sample size [ 57 ] , and pseudo - absences [ 14 , 65 , 66 ] . by explicitly evaluating the effect of background extent on auc scores for these species , the artifacts that arise from modeling should become evident [ 66 ] . to untangle artifacts of modeling from effects of life history traits , i generated a second set of models for narrow ranging endemics using a reduced background extent ( extent restricted to states where a cbc circle recorded a presence ) and then compared the auc scores from the two models sets using t - tests to assess if background extent impacted estimates of model performance . since sampling size and the number of background points were held constant , and therefore neither sampling prevalence or sample size should be affecting differences among the sets of models , a significant difference between the models ( full extent versus reduced extent ) suggests that pseudo - absence selection influences auc scores . if the models do not differ statistically , the higher auc scores recovered for narrow ranged species may reflect a true effect of the underlying species ecology .

models for both neotropical migrants and residents had high levels of model accuracy , while models for temperate migrants had markedly reduced accuracy ( fig 2 ) . among the six major habitat categories included in these analyses , model accuracy for wetland species exhibited a large amount of variation , although the mean auc was high ( fig 2 ) . the wilcoxon test found support for significant differences in accuracy for both range components ( e . g . widespread vs narrow , common vs rare ) ( table 4 ) .

berkeley’s population more than tripled in the first ten years of the 20 th century , gale said . train construction boomed , accommodating the new residents — and then “the whole thing came crashing down in 1913 , ” due to major financial and legal problems throughout the system , gale said . streetcars and some trains ran until the 1940s and 1950s , until they were gradually replaced by buses .
do any of you old timers remember a berkeley sailboat model with a 36″ preformed hull that was a yawl named the “tiki” as i recall . i wonder if these kits ever show up on ebay . if so , what sort of price might these go for . i built one of these back in the late fifties and i think the price might have been around $ 30 at that time .

i also built a flew several of the berkeley control liners ; a sr . puddle jumper was about the first . later , a p - 6e very neat model . also my first r / c was a henry struct “bootstrap” , then a “rc sea cat” . i know i bought a scale b - 25 but never built it and i do not know where it got lost . i still have an in the box , control line stunt . 60 size “snark” .
a total of 555 models were constructed ( 15 models for each species ) . as previous analyses have demonstrated equivalent model performance with full versus subsets of environmental variables [ 16 ] , and i had no a priori information by which to select variables across the modeled set of species [ 40 ] , i used 19 bioclimatic variables for model building ( s1 table ) . however , there are two schools of thought regarding variable selection when using maxent [ 41 ] , one suggests including all reasonable predictor variables [ 38 , 42 , 43 ] , the other suggests removing collinear variables [ 41 ] . in maxent , allowing more predictor variables allows more complex model fitting , and by default maxent determines which predictors to use based on the number of occurrences in the dataset [ 44 ] . maxent uses weighting for variable selection , as well as an l1 - regularization procedure that penalizes models in which predictor variables with little or no contribution are included [ 41 , 45 ] , thus it is generally thought to be less sensitive to model over - fitting than other methods [ 42 , 43 ] ( but see [ 46 ] ) . furthermore , if the relationship among variables is not constant over time , the inclusion of multiple collinear predictors has been found to produce better performance and fit as compared to reduced variable models [ 47 ] . however , if variables are highly collinear , ecologically relevant predictors may be excluded if a collinear variable better explains the response variable [ 40 , 48 ] . from a purely statistical standpoint , reducing collinear variables reduces the potential for mis - identification of critical variables [ 40 ] . to better understand the potential impact of collinearity among the predictor variables in the maxent models , and the constancy of variable relationships across decades , i calculated variance inflation factors ( vif ) using the r package usdm [ 49 ] .
i had to carve the fuselage thin enough to see light through , to keep weight low . i used 4 golden bee motors which performed so well for decades . the nose art was great , took first in cl scale at the nats . hard to describe how much fun and education i derived from that one berkeley b - 17 flying fortress kit . today it would have been rc , rc in the early 60s could not always be adapted too easily for some airplanes . .
by this time the summer work was paying better , and i was able to buy a dennymite motor , which was one of the best ones built at the time . i built several different models around that dennymite motor , and i placed in quite a few contests , and won one ( free flight , i believe ) . in retrospect , the gas models were more of a challenge , but i learned more from building rubber models because they built easily , and because i was able to try out so many different thoughts . i learned quickly that a triangle fuselage was stiffer than a rectangular one , that diagonal verticals were stiffer than straight ones . regardless of what charles hampson grant said in his center of lateral area theories , i found that if i put the wing up front on a high pylon , it stayed right side up . i learned that if you wanted a model to catch and stay in a thermal , that you had to cut down the rudder area to the bare minimum . i learned that an all weather airplane , one that you could fly in the rain , won more hardware than a fair weather ship that was a tremendous flyer .
there are berkeley kits around , if you know where to look . check out model airplane swap meets , poke around in the stacks of dusty old kits you might be fortunate enough to run into , and you could be lucky enough to spot one of the old red , black and white kit boxes . they are considered collector’s items , and the few that have survived the years in excellent condition command serious prices . i have never considered myself a collector , but i am very much interested in old time balsa wood airplane kits like the berkeley line that are no longer pristine or even complete but preserved well enough that a determined , skilled aeromodeller can actually build an airplane from them . for me , building a model airplane i remember from my youth , using all the skills i have acquired over the years to do a far better job than i could ever have dreamed of in those days , and then actually flying it using state - of - the - art micro radio control and electric power is a nostalgia trip to write home about .
i found the caption page yesterday , finally . this is the page i had trouble finding again . i remember that easy built had a couple of kits that they touted as r / c models . i suppose the pt - 19 was one of them ? i did find a tigerkitten kit on ebay yesterday and its now on its way to me . i always liked the lines of that model .
johnston is expecting his initial audience to be largely made up of collectors and historians , but he hopes to eventually tear kids away from their digital distractions and reintroduce them to the classic pastime . eventually , he hopes to collaborate with current transit agencies to make models of contemporary trains . he made himself a model of a bart car , which he keeps in his pocket as a lucky charm when he takes the train to work .
later , while i was at wright field , anderson finished the tool and sampled it . they then sent me sample parts . i was able to get a machine shop in dayton to machine up the parts for the first die cast . 59 . a few weeks later i was discharged from service . i took my newly made motor back to los angeles . at that time i didn’t have any models or any place to build one .

in order to test the temporal transferability of enms , i build models using historical data from fifty years of field surveys ( 1950 to 1999 ) in combination with historical climate data and project them to the “future” ( in this study “future” refers to 1960 to 1999 ) . the projected models were validated through comparison with survey data from the time period to which they have been projected . model validation using serial temporal sampling is becoming more common ( for recent examples [ 19 , 25 ] ) , providing an independent means for assessing model accuracy [ 24 ] . since differences between modeling approaches are less impactful and insightful than other factors when evaluating transferability [ 6 , 7 , 11 ] , rather than focusing on the transferability of different modeling techniques ( see [ 11 , 37 ] for recent reviews ) , i use a single model type with high extrapolative ability . using historical data in this manner provides a more robust framework for evaluating temporal transferability than consensus modeling approaches since consensus approaches emphasis precision rather than accuracy [ 6 ] .
the house we had lived in was repossessed . fortunately , my father had owned a vacant lot and was able to buy a milk shed for $ 15 . 00 . we moved the milk shed onto the vacant lot . shortly after this the economy started easing up a little bit . no matter how tight things were , though , i was able to come up with 75 cents or $ 1 . 00 a month to send away for model building supplies , and i kept building models after school all of this period .
the decreased transferability found in this study could have potentially arisen due to some of the specific characteristics of the data utilized in these analyses . for some species , the range limits of the winter range extend beyond the borders of the continental united states , and these areas were not used in constructing enms . projecting to highly novel climates , can lead to decreased transferability if the entire geographic range is not sampled [ 85 ] . this arises because some combinations of climatic variables are not included during model building , which can result in models that do not capture the upper and / or lower ends of the environmental envelope [ 85 ] . this could underlie some of the instances of under - prediction found here , but does not explain over - prediction . furthermore , the climates in these analyses are analogous across all decades . there is no evidence to suggest that novel climatic combinations existed during the 50 years ( as assessed by the absence of clamping and with the mess statistic ) . as such , models should be both highly accurate and temporally transferable within the continental united states .
here i examine the relationship between life history characteristics and model accuracy and transferability for a subset of north american birds . i use historical occurrence records in combination with historical climate data to forecast to the current climate and to validate the models . using historical data to assess model accuracy and behavior is a highly informative approach to model validation , and is the only direct method to assess temporal transferability [ 11 , 15 , 19 , 24 ] . i quantify model accuracy , parameterization , and transferability , and then use generalized linear models to relate differences in these measures to differences in life history characteristics among species . this is done over a relatively short time period ( 50 years ) in a region where climate is roughly analogous , thus the expectation is that transferability should be very high unless they are impacted by either artifacts of modeling or life history characteristics . this study focused on species with relatively steady ranges over the past fifty years rather than those with documented range shifts . by doing so it becomes more straightforward to disentangle artifacts of modeling from the effects of life history traits on predictive accuracy and transferability .
the commonness or rarity of the species ( range ) was a significant predictor for oi but not rss ( table 3 , fig 3 ) . the oi was higher for rare birds indicating better agreement between the im and em models than for common birds , interestingly , glms did not find any of the life history characteristics examined here to be significant predictors of model transferability as measured by ti h or ti w metrics ( table 3 ) , although the wilcoxon test did recover significant support for differences in transferability for narrow versus widespread species ( table 4 ) .
