nymphonidae is a family of sea spiders which has representatives in all the oceans .

this family contains some 250 species , most of which are found in the genus nymphon .

nymphonid bodies are between 1 and 15 mm long , the extent between the points of the legs reaching 150 mm .

most species are predators of hydroids .

monophyly of nymphonidae is better supported than that of the ammotheidae as shown in cladistic and molecular phylogenetic analyses ( arango , 2002 , 2003 ; arango and wheeler , 2007 ; nakamura et al . , 2007 ) . ascorhynchidae , which was originally established by hoek ( 1881 ) , is revived for the group including ascorhynchus and eurycyde isolated from the traditional ammotheidae ( nakamura et al . , 2007 ; bamber et al . , 2015 ) . chow et al . ( 2012 ) made the first molecular phylogenetic study including nymphonella ( n . tapetis from japan ) . their 18s rdna data strongly suggested a close affinity between nymphonella and ascorhynchus ; the position of nymphonella within ascorhynchidae however , was , not determined .

the sea spiders characteristic body form involves a cephalon and trunk comprising four body segments , each of which bears a pair of walking legs . in addition , the cephalon bears an anterior triradiate proboscis , and primitively a pair of chelifores , a pair of palps , and a pair of ovigerous legs ( ovigers ) , these last being a feature exclusive to the pycnogonida . dorsally , the cephalon primitively bears an ocular tubercle with four eyes . variations on this theme include atrophy or loss of chelifores , o palps and / or ovigers , and , particularly in deeper water forms , loss of eyes and even of the ocular tubercle . further , there are six polymerous species known , four having five pairs of legs and two having six pairs .
these relatively simple creatures with relatively small bodies and long legs , have gut diverticula extending into chelifores and along the legs , and the last trunk segment bears a small abdomen with a distal anus . sea spiders lack respiratory organs or structures , and gas exchange occurs through the cuticle ; recently woods et al ( 2017 ) demonstrated how sea spiders use gut movements for internal transport of oxygen .
where reproduction is known , the male carries the eggs attached to the ovigers , whence they hatch either as a protonymphon larva or as an advanced postlarva . a review of the different pathways of postembryonic development in pycnogonida is found in brenneis et al . ( 2017 ) . pycnogonids have no active dispersal ability , but some taxa , for example species of anoplodactylus and bathypallenopsis , are passively dispersed by medusa , achieving wide geographical distributions . the antarctic species nymphon australe is known as circumpolar , however , it is yet not clear what dispersal mechanisms are involved .
feeding is generally understudied , but appears to be restricted to sessile animals and , occasionally , algae : certain species from epizoic communities on rocks or algae are known to feed on bryozoans , cnidarians and filamentous algae . the diet of the many species collected from soft sediments is unknown . the biology of sea - spiders is markedly understudied . the most recent comprehensive review of their biology is by arnaud & bamber ( 1987 ) . extensive bibliographies are to be found in fry & stock ( 1978 ) and nakamura & child ( 1991 ) .
the fossil record is still sparse ( only four pycnogonid fossil records where known by early 2000s ) but new forms have described in recent years . so far , there is one known species from the upper ordovician ( ca . 450 ma ) , one from the lower silurian ( ca . 425 ma ) , five from the lower devonian hunsrück slate ( germany ) ( ca . 400 ma ) , and three from the jurassic ( 150 ma ) .
pycnobase is based on bamber’s ( 2007 ) attempt of a holistic interpretation of the pycnogonida classification , with subsequent amendments : notably , nymphonella moved to the ascorhynchidae , pycnofragilia added to the ascorhynchidae , and pycnosomia added to the phoxichilidiidae . however , these and other groupings are yet to be tested under a robust and comprehensive phylogenetic approach , in a follow up to the phylogeny in arango & wheeler ( 2007 ) .
it is evident from recent surveys , both from shallow waters and particularly in the deep sea , that numerous species of pycnogonid await discovery . at the same time , molecular analyses are indicating the existence of cryptic species in what had been thought to be widespread taxa . this database must therefore be a working document and it will certainly continue expanding , hopefully contributing to a better understanding of the world’s pycnogonids .

if any data constitutes a substantial proportion of the records used in secondary analysis , the editor ( c . arango ) or managers of the database should be contacted . in any case , there are additional data which may prove valuable to such analyses .
the site welcomes input from colleagues and visitors who detect errors or omissions . note that sadly , roger bamber passed away in february 2015 and aliya el nagar who played a key role developing the database is no longer associated to the maintenance of pycnobase . the current editor strives to maintain the website as both a comprehensive and an up - to - date resource through regular updates .

scientists aim to describe a single ' tree of life ' that reflects the evolutionary relationships of living things . however , evolutionary relationships are a matter of ongoing discovery , and there are different opinions about how living things should be grouped and named . eol reflects these differences by supporting several different scientific ' classifications ' . some species have been named more than once . such duplicates are listed under synonyms . eol also provides support for common names which may vary across regions as well as languages .

the fauna wetland indicator species list ( wisl ) has been compiled to support the determination of whether a site is a wetland . wetland indicator species ( wis ) have adapted to living in wetlands and are dependent on them for all or part of their lives . some spend a major part of their life there , whereas others only use them for critical stages of their life cycle , such as breeding and larval development .
the presence of a wis at a site does not , in itself , confirm the site to be a wetland , but is one line of evidence towards determining the wetland status of a site .
species are dependent on water and need to be immersed in water , or floating upon water , for their total life cycle .
require water for most of their life cycle stages or for a critical stage in their development .
the wisl includes mainly the more common fauna species . most rare species and all vagrant fauna species have not been included . species , other than those listed , may also be wetland indicator species for a certain locality given expert recommendation and reliable site specific data .
most marine species are also not included in the wisl as the wetland definition excludes marine water more than 6m below low tide .
knowledge of the species geographic distribution and behaviour will aid interpretation of some recorded observations . expert advice may be required when wis are recorded in an area without other identifiable wetland characteristics as the species may be :
travelling between wetlands ( e . g . crayfish , eels , crocodiles and birds )
using adjacent non - wetland habitat for a period of their life cycle or lifestyle ( e . g . chelidae freshwater turtles laying eggs on dry ground )
forced into less preferred non - wetland habitat due to overpopulation pressures ( e . g . swamp rat ) .
the species groupings below are divided into subgroupings which contain species with similar habitat needs and behaviours . the wis lists have been grouped in 7 tables and are all at a species level except for insects and spiders .
there is little knowledge about queensland’s freshwater crustaceans . expertise should be sought when using class crustacea as a wetland indicator species as some species are considered amphibious during their life cycle and may appear outside the wetland environment .
this section includes only the macro freshwater crustacean species within class crustacea , order decapoda and family either palaemondae ( freshwater crabs ) or parastacidae ( freshwater crayfish ) .
all wild fish—chondrichthyes ( cartilaginous fish ) and osteichthyes ( bony fish ) —recognised as recorded within queensland are considered to be wis , depending on their typical habitat’s physical characteristics as compared to those described in the queensland wetland program wetland definition .
the fish species in this list largely belong to the freshwater fish that are bed spawners ( demersal ) with the non - floating eggs sinking to the water column bed or adhering to submerged rocks or vegetation .
other fish ( diadromus ) are dependent on estuarine and lower freshwater habitat early in their life cycles . the free floating young then move from the estuarine to the marine environment for their mature lives either breeding at sea or returning to estuarine or freshwater environments to breed .
some species move downstream to breed in the brackish water or even seawater and then migrate upstream ( catadromous ) . examples of these are australian perch and barramundi .
more extensive queensland fish species lists are available from the department of agriculture and fisheries ) . queensland’s watercourses and estuaries are populated by freshwater and estuarine elasmobranchs ( rays , bull sharks , sawfish ) . the taxonomy , distribution and status of these creatures are poorly known and because of this expert guidance is essential if considering these as wetland indicator species .
note that species that may spend a part of their life in a marine environment are outside the scope of this guideline .
these creatures live most of their lives in aquatic ecosystems and are therefore considered wetland indicators .
frogs are amphibians , usually going through 3 distinct life cycle stages from eggs to aquatic larvae ( tadpole ) and air breathing adults . expert opinion should be sought as these animals may live at least one stage of their life cycle outside wetland habitats . the frog species selected for these lists are the most hydrophilic frog species whose life cycle fits within the queensland wetlands program wetland definition ( animals that are adapted to and dependent on living in wet conditions for at least part of their life cycle ) .
these frog species are considered to live an entirely aquatic life . one species is noted as being in seepage areas . as most members of the family microhylidae lay eggs on the land and are arboreal or terrestrial
these species do not spend all life stages ( egg , tadpole or maturity ) within the aquatic environment . these species can be indicators of wetland conditions , but require expert interpretation of their associations with wetlands .
for these species , the aquatic environment is essential for the early life stages ( egg and tadpole ) , and the mature stage is not aquatic but burrowed except for breeding events . therefore , these species are only an indicator for possible wetland conditions in the egg and tadpole stages , and during breeding events .
the birds listed in the following tables are selected for their close relationship with wetlands . to assist with identification , the lists have been divided into categories of species that share similar behaviour and habitats .
these lists include species that are easy to identify but are not complete lists of wetland species . uncommon and vagrant species are not included . it is important to note that some species in these lists may be recorded out of wetland habitats because they migrate or move during dry periods . this does not interfere with their status of wetland indicators but means that data used as wetland indication may require expert interpretation .
it is also important to recognise that while most wader birds breed in wetlands of the northern hemisphere , they remain faithful to wetland sites when in australia .
these species are wetland specialists but do not spend their entire life in the water environment .

we obtained the nucleotide sequence of 18s rdna of nymphonella tapetis , a pycnogonid endoparasitic on some bivalves , together with that of other species belonging to ascorhynchidae hoek , 1881 . the phylogenetic tree based on these sequences as well as those of selected species from a database strongly supports the monophyly of ascorhynchidae and the inclusion of nymphonella in the family . nymphonella seems to be an aberrant form in the ascorhynchidae , but multi - gene analysis with more species is required for the exact determination of the taxonomic position of the genus .
in this study we used the nucleotide sequences of 18s rrna with a selected taxon - sampling for analysis to discuss the taxonomic position of nymphonella in ascorhynchidae .
( adult male , off kii - nagashima , mie , no further data ) .
genomic dna was isolated from absolute ethanol - preserved specimens using ez1 dna tissue kit ( qiagen , valencia , ca , usa ) . depending of the size of specimens , a whole leg or a part of leg was cut off from body , and macerated with a plastic pestle in a
tube containing the lysis buffer ( buffer g2 ) and proteinase k . the tubes were then kept at
until the tissues were completely lysed . isolation of genomic dna was performed using ez1 advanced instrument ( qiagen ) according to the manufacturer’s instructions .
for pcr amplification , 10 ng of genomic dna was used for each reaction . amplification was made in a
for kod fx neo and 0 . 5 unit of dna polymerase ( kod fx neo ; toyobo , tokyo , japan ) . amplification of the 18s rrna region was carried out using primers 18su and 18sl (
. the dna fragments were separated with electrophoresed in a 0 . 7 % agarose gel , and were purified using qiaquick gel extraction kit ( qiagen ) . nucleotide sequences were determined with an abi 3730 dna analyzer ( applied biosystems , foster city , ca , usa ) using a bigdye terminator v3 . 1 cycle sequencing kit ( applied biosystems ) . sequences produced in this study are deposited in ddbj / embl / genbank as follows ;
) . there were a total of 1435 positions containing with gaps in the final dataset and missing data were eliminated . the evolutionary history was inferred by using the maximum likelihood ( ml ) method based on the
with mega6 . initial tree for the heuristic search was obtained automatically by applying neighbor - joining ( nj ) and bionj algorithms to a matrix of pairwise distances estimated using the maximum composite likelihood approach , and then selecting the topology with superior log likelihood value . the tree is drawn to scale , with branch lengths measured in the number of substitutions per site . ml bootstrap values were determined using 1000 replicates . we also performed the nj method (
) using same data set and calculated bootstrap values ( 1000 replicates ) . nucleotide sequences of 18s rrna from
the phylogenetic tree by the nucleotide sequences of 18s rrna using the ml method is shown in fig . 1 . the identical tree - topology was obtained with the nj method .
phylogenetic relationships of sea spiders deduced from the ml method using nuclear encoding 18s rdna gene partial sequences . the tree with the highest log likelihood
is shown . the sequences determined in the present study are indicated by closed circle . numbers above branches indicate bootstrap values of ml ( left ) and nj ( right ) analysis .
the traditional taxonomic system of pycnogonids was based on gross morphology , particularly the presence / absence of head appendages ( stock , 1994 ; bamber , 2007 ) . recent analyses using modern techniques , however , reveal that some of the families are apparently polyphyletic ( arango , 2002 , 2003 ; arango and wheeler , 2007 ; nakamura et al . , 2007 ) . isolation of ascorhynchus and eurycyde from their traditional placement in ammotheidae was well supported by morphology , molecules , and their combined analyses ( arango , 2002 ; arango and wheeler , 2007 ; nakamura et al . , 2007 ) .
nakamura et al . ( 2007 ) revived ascorhynchidae for the two genera although their tree showed a paraphyletic ascorhynchus . arabi et al . ( 2010 ) pointed out , however , that the paraphyletic pattern was due to the mis - rooting probably due to an inappropriate selection of out - group . in this study , the phylogenetic tree by the nucleotide sequences of 18s rrna shows a very high support for the ascorhynchus - eurycyd - clade both in the ml and the nj methods ( fig . 1 ) . the monophyly of the family was not strongly supported by 18s - based analyses of chow et al . ( 2012 ) . it was presumed that a high similarity of sequences of out - group species suppressed the probabilities and bootstrap values in their tree ( nei and kumar , 2000 ) .
in pycnogonids , the taxon sampling and the sequences are still not sufficient for a detailed phylogenetic reconstruction . in addition , more biological information is required for an appropriate evaluation on the evolution of their traits , e . g . , endoparasitism in n . tapetis .

the greater horseshoe bat ( rhinolophus ferrumequinum ) is a european bat of the rhinolophus genus .

its distribution covers europe , africa , south asia and australia .

it is the largest of the european horseshoe bats and is thus easily distinguished from other species .

the species is sedentary , typically travelling up to 30 km between the winter and summer roosts , with the longest recorded movement being 180 km .

the species is notable as having the oldest recorded age for any european bat , with a bat living for over 30 years .

the frequencies used by this bat species for echolocation lie between 69 – 83 khz , have most energy at 81 khz and have an average duration of 37.4 ms.

there are approximately 100 species of horseshoe bats which belong to the rhinolophus genus . the single species of greater horseshoe bats , or rhinolophus ferrumequinum , is the largest species of horseshoe bats , who get their names from the facial flesh that resembles the horseshoe .
maximum age recorded in europe is 30 years ( schober & grimmberger , 1989 ) . greater horseshoe bats have the longest recorded age of any european bat .
the greater horseshoe bat is one of britain ' s largest , found in southwest england and south wales . it is also found in north africa and asia . the species is known for its unique mouth structure and monogamous mating habits . the greater horseshoe bat population is declining , making conservation efforts a priority .
 the greater horseshoe bat is listed in the uk biodiversity action plan and is one of the rarest mammal species in the united kingdom . the main threats facing greater horseshoe bats are the loss of roost sites and foraging areas ( duvergé & jones , 2003 )

as part of the devon greater horseshoe bat project , a camera has been installed in one of our large greater horseshoe roosts . you can see some fantastic live footage on the website of the bats in the roost . the best time to watch it is just before sunset when the bats are flying around inside the roost in preparation to emerge for the night . visit the devon greater horseshoe bat project website to view the live footage .
the british population of greater horseshoe bats has declined and is now very fragmented . analysis by rossiter et al . ( 2000b ) showed that welsh populations of greater horseshoe bats are genetically isolated and have relatively low genetic variation .
the echolocation call of greater horseshoe bats is constant frequency with a frequency modulated component at the start and end .
 greater horseshoe bats are on the verge of becoming a threatened species worldwide ( iucn status , 2001 ) .
the greater horseshoe bat is found in central and southern europe but has declined significantly in northern europe . in the uk it is restricted to southern england and south wales .

the greater horseshoe bat earned the title of greater because it is larger than other species of horseshoe bats , which are sometimes called lesser horseshoe bats . the greater horseshoe bat weighs up to 34 grams or about 1 . 2 ounces , and has a body length of 58 to 70 millimeters or 2 . 3 to 2 . 7 inches . this is considerably larger than the lesser horseshoe bats , who may weigh only 5 to 9 grams , or about one - third of an ounce with a body length of 35 to 45 millimeters or approximately 1 1 / 2 to 2 inches .
this site in south - west wales contains the main hibernation site for the population associated with pembrokeshire bat sites csac . it may thus be used by up to 5 . 5 % of the uk population of greater horseshoe bat rhinolophus ferrumequinum .

the greater horseshoe bat ' s name precisely describes the animal ' s most distinct characteristic . the species '
horseshoe
is the u - shaped structure surrounding the bat ' s nose . also called a noseleaf , this fleshy facial feature enhances echolocation , a process that the bat uses to navigate distance and locate prey . the bat makes noises that vibrate and amplify through the nostrils and off the noseleaf , then travels and bounce off surrounding objects , giving the bat direction and leading it to insects to eat .

the greater horseshoe bat is rare in the uk with a distribution restricted to south - west england and south wales . it is absent from scotland and northern ireland . it is also recorded in the channel islands .
known threats to this bat are roost destruction and disturbance . two mines used by the greater large - eared horseshoe bat as roosts have been disturbed or destroyed . it is also suspected that human roost disturbance of roosts and over - collection from well - known colony sites is affecting the species .
trends from both the hibernation survey and roost count show a statistically significant increase in the smoothed population index since the baseline year . overall the population of greater horseshoe bat in great britain is considered to have increased since 1999 .
nocturnally active , the greater large - eared horseshoe bat captures insects ( beetles and moths ) from the air or surfaces during flight . their flight is slow and fluttery . it lands to rest and to consume its prey .
a recovery plan for cave - dwelling bats , rhinolophus philippinensis , hipposideros semoni and taphozous troughtoni 2001 - 2005 has been developed . the recovery plan outlines management actions for the conservation of the greater large - eared horseshoe bat .

foraging habitat management - suitable habitat for foraging should be maintained and where possible expanded within 2 km of roost sites . in the case of the greater horseshoe bat , good habitat includes broadleaved woodland and unimproved grassland , rather than coniferous woodland or improved grazing .
this horseshoe bat has very large ears and a yellow or grey noseleaf . its large ear length distinguishes it from the eastern horseshoe - bat , rhinolophus megaphyllus , which has smaller ears . its fur is grey to brown on the back and slightly lighter on the belly . it can weigh between 8 . 3 – 16 . 2 g .

the greater large - eared horseshoe bat can be found in north queensland , from townsville to cape york . the smaller form ( sometimes referred to as r . philippinensis achilles ) is restricted to the more northerly parts of the species ' distribution , on iron range and mcilwraith range on cape york .
the greater horseshoe bat population of northern europe has declined significantly over the last 100 years ( an estimated decline of 90 % ) , such that the uk population is now restricted to south west england and wales ( although occasional specimens are recorded elsewhere ) . there are currently 35 recognised maternity ( and all year ) roosts and 369 hibernation roosts in the country , with the population estimated to be between 4 , 000 and 6 , 600 individuals . internationally , the greater horseshoe bat occurs throughout the area between the atlantic coast of europe and japan , but the population appears to be declining almost everywhere .
greater horseshoe bats ' median emergence is 25 minutes after sunset ( jones & rydell , 1994 ) and they return to the roost 5 - 30 minutes before sunrise ( duvergé and jones , 1994 ) .

mells valley in southern england is selected on the basis of the size of its exceptional breeding population . it contains the maternity site associated with a population comprising about 12 % of the uk greater horseshoe bat rhinolophus ferrumequinum population . a proportion of the population also hibernates at the site , though other hibernation sites remain unknown .
this site in south - west wales supports approximately 9 . 5 % of the uk greater horseshoe bat rhinolophus ferrumequinum population . it represents the species at the north - western extremity of its range . the site contains a mixture of maternity , transitory and hibernation sites and so demonstrates good conservation of features required for survival .

this complex of sites on the border between england and wales represents greater horseshoe bat rhinolophus ferrumequinum in the northern part of its range , with about 6 % of the uk population . the site contains the main maternity roost for bats in this area , which are believed to hibernate in the many disused mines in the forest .
 a study by duvergé and jones ( 1994 ) found that greater horseshoe bats preferred the following habitats ( in descending order ) : pastures with cattle ( either single / mixed stock ) , ancient semi - woodland and pastures with non - cattle stock . woodlands and pasture close to woodland were used to a greater extent in spring and early summer while pasture was predominantly used in summer . rides , footpaths , hedges and treelines were used by greater horseshoe bats when flying in these feeding areas . the bats were generally less than 2m away from these structures .
the greater horseshoe bat ( rhinolophus ferrumequinum ) is the larger of the two horseshoe bats found in britain . they are so - named from the horseshoe shaped nose ' leaf ' , used as part of the bat ' s echolocation system . the ears are leaf - shaped and have a sharply pointed tip . the fur is thick , and coloured ash - grey above , and buff underneath . bats are not blind as was once popularly thought . they have good eyesight but rely on their echolocation to navigate and to detect their insect prey . they emit a succession of high - pitched squeaks and judge their position and the location of their prey from the reflected echoes .
install bat gates , fences or develop other appropriate protective systems to prevent human disturbance of roost and maternity sites .

the greater horseshoe bat is a relatively large species by british standards ( forearm : 51 - 59 mm ; head and body : 56 - 68 mm ; wingspan : 360 mm ; weight : 13 - 34 g ) , with medium to light brown fur ( often greyer and paler on the animals underside ) , a horseshoe nose - leaf and long legs ( with which it hangs from its roost , often with its wing wrapped around its body ) .

 in order to protect greater horseshoe bat colonies , duvergé & jones ( 2003 ) suggest that permanently grazed pastures should not be ploughed and used from arable crops and that woodland and hedgerows should be retained . hedegrows should be approximately 4m high and 2 - 3m wide and should not be intensively trimmed . important habitats within 4km of roost sites should be preserved .

the 919 maternities assigned during the period between 1993 and 2011 were shared among 216 individual females . female greater horseshoe bats showed considerable variation in total reproductive success among breeding females across the 19 year period , which ranged from one to eighteen pups (
the greater horseshoe bat has declined by over 90 percent in numbers during the last 100 years . this is due largely to habitat loss , caused by modern intensive farming methods . the destruction of woods , roosting sites , old pastureland , and the use of chemical insecticides , which have seriously reduced the abundance of their insect prey , have all contributed to this decline .

greater horseshoe bats are declining in numbers in all regions where they dwell . the population has decreased up to 90 percent in a century . increasing human populations , urbanized forests and pastures , and a decreased food supply as the result of insecticides are possible causes of the species ' declining numbers . throughout much of europe , the species is protected by law and its habitats monitored and conserved . in recent years , greater horseshoe bats have become prevalent on organic farms because of the natural , pesticide - free environment afforded .

duvergé and jones ( 1994 ) found that the diet of greater horseshoe bats mainly consisted of lepidoptera and coleoptera ( 30 - 45 % ) , followed by diptera ( 10 - 20 % ) and hymenoptera ( 5 - 10 % ) , although these proportions change seasonally .

protection of roosts - greater horseshoe bats are sensitive to disturbance , especially of their nursery and winter roosts ; consequently these sites need to be protected and entrances left unobstructed ( in some cases , grids that allow access for bats , but prevent human access may be used ) .

the greater horseshoe bat is classified as least concern ( lc ) on the iucn red list ( 1 ) . it is classified as endangered in the uk , listed under appendix ii of the bonn convention , appendix ii of the berne convention , annexes ii and iv of the ec habitats directive , schedule 2 of the conservation regulations 1994 and protected in the uk under schedule 5 of the wildlife and countryside act ( as amended ) .
south hams in south - west england is thought to hold the largest population of greater horseshoe bat rhinolophus ferrumequinum in the uk , and is the only one containing more than 1 , 000 adult bats ( 31 % of the uk species population ) . it contains the largest known maternity roost in the uk and possibly in europe . as the site contains both maternity and hibernation sites it demonstrates good conservation of the features required for survival .
park et al . ( 2002 ) studied torpor , arousal and activity in free - living greater horseshoe bats and found that arousal tends to be closely synchronized with dusk . as the temperature increased , the bats ' torpor bout duration decreased , probably because of the increased rate of water loss .

horseshoe bats are named after the shape of their noseleaves , a complex horseshoe - shaped fold of skin used to emit echolocational calls and help focus the sound . broad , round wings provide these bats with excellent manoeuvrability and agility in tight spaces , with many species actually able to hover and pick insects off surfaces and spiders ' webs . horseshoe bats also have a unique roosting posture , wrapping their wings around their body and enshrouding themselves . however , the 100 or so horseshoe species have an array of roosting habits , from large cave colonies to hanging in the open among tree branches .
this site in south - west england is selected on the basis of the size of population represented ( 3 % of the uk greater horseshoe bat rhinolophus ferrumequinum population ) and its good conservation of structure and function , having both maternity and hibernation sites . this site contains an exceptionally good range of the sites used by the population , comprising two maternity sites in lowland north somerset and a variety of cave and mine hibernation sites in the mendip hills .
) found a much greater effect of land - use compared to climate . however , the assessment of bat activity and species distributions across broader scales , such as across the british range of species has revealed the great importance of meteorological variables in addition to land - use and landscape characteristics ( walsh and harris

greater horseshoe bats appear in appendix ii of the berne convention ( convention on the conservation of european wildlife and natural habitats ) . this requires that they be strictly protected against deliberate killing , capture , damage / destruction of breeding and nesting sites , disturbance , trading ( including parts and derivatives ) , etc .

 duvergé and jones ( 1994 ) found that a range of high - quality foraging areas is essential for the survival of greater horseshoe bats . they therefore suggest the conservation of ancient semi - natural , deciduous and mixed woodlands . pasture with cattle grazing is also very important ( duvergé & jones , 1994 ) . thick hedgerows , treelines or fences along the field boundaries should be maintained as prey tends to accumulate on the leeward side of these structures and because they provide perch sites and travel routes for the bats . duvergé and jones ( 1994 ) suggest that key habitats within 4km of a greater horseshoe roost site are maintained or improved .
greater horseshoe bats often roost in buildings during the summer , and their presence can be detected by piles of excrement on the ground . they leave their roosts just after sunset , and during the summer , spend about an hour feeding before returning . they often feed again just before dawn . at the end of august they stay on the wing all night . greater horseshoe bats mate in autumn , sometimes in late winter or early spring . they form maternity roosts in may and the young are born in mid - july . this species reaches maturity at around three years old and they may live for 30 years . their preferred food is large beetles , such as cockchafers and dung beetles , large moths and caddis flies . they have been observed watching from a regular roost and then flying out to take passing insects . greater horseshoe bats hibernate in caves , cellars or disused mines , from late september to mid - may . they may emerge to feed during mild spells .

 foraging habitats may be lost through changes in land - use or farming practices or the removal of linear features such as hedgerows . greater horseshoe bats may also be at risk from chemicals used on nearby vegetation , if they either come into contact with that vegetation or consume insects that have been sprayed or eaten sprayed food . there is some indication that the use of avermectin worming compounds may impact on bat activity via its effects on insects in the cowpat community ( duvergé & jones , 2003 ) .

we studied the determinants of male and female reproductive success in wild greater horseshoe bats ( rhinolophus ferrumequinum ) by examining patterns of parentage over a 19 year period between 1993 and 2011 . based on a likelihood method , mothers were assigned to 99 . 5 % and fathers to 76 . 8 % of 924 pups born into the woodchester population .
this study demonstrates the value of long term , standardised monitoring of bat maternity roosts when assessing the impact of conservation management . in accordance to other studies ( duvergé and jones

 roost sites may be lost as buildings ( especially those associated with farms ) are converted or become derelict . a range of buildings are needed for activities such as mating , breeding and night roosting . greater horseshoe bats may also be at risk from chemicals used within roost sites , for example , remedial timber treatment ( duvergé & jones , 2003 ) .

greater horseshoe bats are a protected species in the u . k . and bats were caught and sampled under licences from english nature and the home office ( ppl 30 / 2513 ) . permission for access to catch bats at the maternity roost was granted by the woodchester mansion trust , and for access to catch bats in caves and mines on land that is privately owned , from the land owners .
although thomas ( 1997 , unpublished thesis ) found very high divergence in mitochondrial dna sequences , csorba et al . 2003 refrained from splitting japanese greater horseshoe bats ( rhinolophus nippon ) from r . ferrumequinum . several subspecies are identified over the range , of which two occur in the western palaearctic : r . f . creticus ( crete ) and r . f . ferrumequinum ( rest of western palaearctic range ) .

a female produces one baby which is typically born during june or july ( schober and grimmberger , 1997 ) . young open their eyes at 7 day and can fly during the third to fourth week . after seven to eight weeks , young are ready to leave the roost . females form maternity roosts in warmer places such as attics to care for the young ( schober and grimmberger , 1997 ) . greater horseshoe bats lose their milk teeth before birth ( nowak , 1994 ) .

summer roosts : nursery roosts are found in attics in old buildings which can be accessed by uninterrupted flight and contain up to 200 females ( greenaway & hutson , 1990 ) . greater horseshoe bats wrap their wings around their body and hang freely by the feet . hang with their offspring either singly or in small groups . adult males may be found in nursery roosts but leave when the young are born in mid summer . males hold the same territory each year , and females return here annually .
the timing of the births of greater horseshoe bats was studied by ransome and mcowat ( 1994 ) for three colonies in south - west wales and south - west england . birth timing was significantly correlated with spring temperature , with young being born earlier after warmer springs . cold springs and late births led to population declines and male - biased sex ratios at all three sites in 1986 , although all the colonies recovered following subsequent warm springs . births were approximately 18 days earlier when temperatures rose by 2°c .
the relationship between forearm length and paternity success among breeding males between 1993 and 2011 ; larger males had greater annual reproductive success . in addition , male forearm length significantly and positively influenced total male reproductive success over the 19 year period between 1993 and 2011 .
greater horseshoe bats have polygynous mating systems although rossiter et al . ( 2000a ) found that some females had offspring from the same male in separate years . fidelity for either individuals or mating sites is likely to explain this behaviour , although it could also be due to sperm competition . females mated with males from their natal colony as well as with males from outside the colony . rossiter et al . ( 2000a ) suggest that gene flow between colonies occurs through male and female dispersal during the mating period .
in contrast to males , analyses of a long - term dataset provided no evidence that maternity success was significantly skewed among breeding females . female reproductive skew is most commonly reported within cooperatively breeding species [ 21 ] , but has also been documented in populations of mammal species that , like the greater horseshoe bat , exhibit reversed sexual size dimorphism , such as the spotted hyena in which there is aggressive competition for males and female reproductive success is strongly correlated with social rank [ 15 ] . however , a lack of evidence of social hierarchy among female greater horseshoe bats , as well as the lack of skew documented among breeders and the observation that female reproductive success does not relate to body size . all suggest that there is little or no intra - sexual competition among females for males in this population . indeed , almost all females that reach breeding age ( ≥2 years ) do successfully breed . our results are more consistent with male - dominated polygynous breeding systems , where female success is less dependent on body size [ 71 ] . the fact that almost all females , but only a third of males , breed within the woodchester population , despite a relatively even sex ratio , supports the commonly held theory that females are more selective when it comes to choosing mates than males [ 64 ] .

this species is listed in the uk biodiversity action plans ( ukbaps ) , and has been included in english nature ' s species recovery programme . it belongs to a family of animals that have been much maligned over the centuries . however , more people are realising just how fascinating bats are , and they receive a high level of legal protection . the main effort in their conservation is to encourage landowners and farmers to manage their land in ways that benefit the bats . they are also being asked to limit the use of ivermectin insecticides , commonly used for treating cattle . the chemical in the insecticide also poisons the cattle ' s dung , and kills the larvae of dung beetles , one of the greater horseshoe bat ' s principal foods . as more people learn about bats , it is hoped that the efforts to conserve them as a breeding species will gain more support . they are an intriguing group of mammals , and undeserving of their sinister reputation . the bat conservation trust carries out work on surveys and monitoring , and employs many volunteers .

besides the extrinsic factors outlined above , intrinsic factors may also have led to the population increase . while it has received little attention in studies on bat populations , the demographic allee effect—defined as a positive relationship between fitness and population size or density ( courchamp et al .

the relationship between heterozygosity and maternity success among breeding females between 1993 and 2011 ; more heterozygous females had greater annual reproductive success . heterozygosity was also a significant predictor of , and positively correlated with , the total number of pups a breeding female gave birth to between 1993 and 2011 .
from other rhinolophids . the first premolar on the upper jaw protrudes from the row of teeth . often this premolar is very small or non - existent . the third and fourth metacarpal bones in the wings are shorter than those of its relatives ( koopman , 1994 ) . the tragus is absent ( simmons and conway , 1997 ) . the length of the head and body ranges from 57 to 71mm , the tail length ranges from 35 to 43 mm and the forearm from 54 to 61 mm . the wing span ranges from 350 to 400 mm , and the weight from 17 to 34 grams . the greater horseshoe bat can also be identified by its color . the back is brownish gray with a slight tint of red , while the underside is a lighter gray color . the membrane that connects the forearm and tail is brownish gray . young
) . these studies demonstrated that regardless of the species , the level of bat activity is not significantly different between matched conventional and aes fields . rather , the amount of particular habitat types within the surrounding landscape seems to be more important for bats ( fuentes - montemayor et al .
the advantage of large body size in greater horseshoe bats , which are not known to court aerially , suggests that males compete for access to females , and that larger males win these contests more often . however , intra - sexual contests between male greater horseshoe bats over females have not been observed ; instead it is thought females actively seek out and choose males in their underground mating territories . consequently females may choose mates either on the basis of their individual traits or on the basis of the quality of their territories , which might differ in their proximity to the maternity roost , suitability as a hibernaculum or the quality of the surrounding habitat for foraging [ 40 ] . taking these observations into account , the mating system of this species probably contains elements of both female choice and male - male competition , whereby any advantage of larger size to males comes from indirect competition for females via direct competition for mating sites . certainly individual sites are normally only occupied by a single male , who is replaced quickly on disappearance , implying strong competition for sites , and we have identified several important sites where the resident male has consistently high paternity success [ 38 ] .
greater horseshoe bats are also protected under annexes ii and iv of the european communities council directive on the conservation of natural habitats and wild fauna and flora . these cover species of community interest the conservation of which requires the designation of special areas of conservation ( sacs ) ; and species that are in need of strict protection respectively . damage or destruction of breeding sites or resting places is prohibited , and all life stages are protected against deliberate capture , killing or disturbance in the wild ; and keeping , transport , sale / exchange and offering for sale / exchange of specimens .
) , yet we found no relationship between amount of land under aes and colony size at the spatial scales and time period studied here . the ineffectiveness of aess for enhancing bat populations in farmland - dominated landscapes has also been reported elsewhere in the uk ( fuentes - montemayor et al .
) . as observed in other bat species , intraspecific competition for food may ( i ) increase flight distances to reach available foraging areas and ( ii ) reduce prey capture rates , both of which may reduce individual fitness . we further found light pollution to be negatively related to colony size .
in addition to catches at woodchester mansion , surveys of all known caves and mines – used as mating sites and hibernacula – within a 25 km radius of the maternity roost are performed during autumn , winter and spring as part of an on - going study of this population [ 35 ] , [ 36 ] , [ 41 ] . during these surveys , greater horseshoe bats present are recorded and , where necessary , ringed and tissue sampled . immigrant adults , especially males , in the population are usually found during these surveys . based on current recapture rates , we estimate that over 90 % of bats in this population have been ringed , including all breeding females [ 38 ] .
this study focused on a maternity colony that assembles each summer in the attic of woodchester mansion , gloucestershire , u . k . ( 51°43′n , 2°18′w ) . greater horseshoe bats have been caught and ringed at woodchester mansion for 54 years , and tissue samples have been collected annually from all offspring born into the colony since 1993 as well as their mothers . primary catches , during which new - born pups are ringed and sampled , take place in early to mid - july , at which time most pups are less than 20 days old and still attached to their mothers . july catches also afford an opportunity to sample any adult females in the breeding colony that have not been previously sampled or ringed .

the diet of the bat rhinolophus ferrumequinum was studied at the zhi’an village of ji’an city in china , from june to august 2004 . the bats were trained in a laboratory ( volume : 9x4x4 m 3 ) . foraging strategies of the bat were observed at night and prey remains were collected and identified . the results showed that the diet consisted mainly of lepidoptera in summer , including 11 families , more than 30 species of moths , such as noctuidae ( 36 . 6 % by number ) , sphingidae ( 24 . 1 % ) , geometridae ( 13 . 4 % ) and limacodidae ( 9 . 5 % ) . the length of culled wings ranged from 10–40 mm ( 97 . 7 % ) . pearson correlation analysis showed that the bat r . ferrumequinum foraged their prey selectively , but not opportunistically . from field studies , two ways were observed in which the bats retrieved their prey including aerial hawking during peak active period of the insects and flycatching during the insects’ non - peak activity period . the bats never gleaned prey from the ground , though they appeared to be well able to detect fluttering moths on the ground .
the 919 maternities assigned during the period between 1993 and 2011 were shared among 216 individual females . female greater horseshoe bats showed considerable variation in total reproductive success among breeding females across the 19 year period , which ranged from one to eighteen pups ( figure 1b ) . this apparent skew was not significant when maternity data for all 19 cohorts were pooled and reproductive success was corrected for the number of years each female was breeding during the 19 year period ( b index = −0 . 0009 , p = 1 , n = 216 ) . because females can only produce a maximum of one pup each year so there was no variance in reproductive success ( and therefore no reproductive skew ) among breeding individuals within years or among breeders of the same age ( figure 3b ) .
