amblycheila is a genus of flightless , nocturnal tiger beetles .

there are seven species distributed across the southwestern united states and mexico .

species include : amblycheila baroni rivers , 1890 – montane giant tiger beetle amblycheila cylindriformis ( say , 1823 ) – great plains giant tiger beetle amblycheila halffteri mateu , 1974 amblycheila hoversoni gage , 1990 – south texas giant tiger beetle amblycheila nyx sumlin , 1991 amblycheila picolominii reiche , 1839 – plateau giant tiger beetle amblycheila schwarzi w. horn , 1903 – mojave giant tiger beetle

amblycheila

…and the distinctly separated hooks on the 5th abdominal segment confirm it is amblycheila .

well , any tiger beetle larva snagged from its burrow is a sight to behold – amblycheila just does it the best .

step 7 . lastly , don’t forget to look at the hump in lateral profile—it is as alien a structure as any in the insect world . in the case of amblycheila larvae , the bed of hairs posterior to the hooks is comprised of much shorter , stouter , and more densely placed hairs than larvae of tetracha .
step 6 . another way to distinguish larvae of the genus amblycheila is by looking at the hooks on the hump of the 5th abdominal segment , best done with a hand lens ( or , even better , with an mp - e65 lens ! ) . all tiger beetle larvae have several pairs of large hooks that the larva uses to brace itself against the wall of its burrow when capturing prey to prevent the struggling prey from pulling the tiger beetle larva out of its burrow . larvae in the genus omus , restricted to the pacific region of north america , have three pairs of hooks ( referred to as the outer , middle , and inner hooks ) , while all other north american tiger beetle genera have two ( having lost the outer pair ) . in amblycheila and tetracha the hooks are simple and thornlike , while larvae of all other north american genera have much longer middle hooks that are curved and sickle - shaped ( e . g . , cylindera celeripes in this post ) . amblycheila larvae can be distinguished from tetracha larvae by the middle and inner hooks on each side being distinctly separated rather than touching at the base ( e . g . , tetracha floridana in this post ) . there is also a cluster of short , stout hairs around the base of each hook in amblycheila that is missing in tetracha ( e . g . , tetracha virginica in this post ) .
amblycheila have been reared in the lab ( a . cylindriformis and a . hoversoni , for example ) ; however , i can’t seem to find any published information with details of the technique . i’m just going by what little information i’ve been able to glean from these sources . contrary to what they have said , a . cylindriformis adults definitely do make burrows and spend much of their time in the burrows .
step 5 . if size alone isn’t enough , you can confirm that the larvae does indeed belong to the genus amblycheila by looking at its eyes—their are two pairs , and the 1st pair ( closest to the mandibles ) are distinctly larger than the 2nd pair . this isn’t clearly visible in the photo above because i doused the larva with water to remove the mud and dirt that encrusted it upon removal from its burrow .

when i pulled the larvae from the site i made sure i gathered enough of the soil they where in for them to burrow . i then set them up in about 1 foot high containers with the soil . they will burrow themselves but it is helpful if you start a small hole for them . then try to keep the conditions of the container as close to the natural conditions as possible , so for this species hot and pretty dry so not too difficult . i would feed them about 2 - 3 small crickets every week and dose them with water about once a month . to get them to pupate can be tricky as it is often environmental ques that cause them to start . i got pretty lucky and just dropped the temp about 10 degrees and then wet the container and it pupated . i am still working on perfecting my methods of rearing but one of the keys is to make sure you gather the soil fomr the larval sites .

step 1 . go to your favorite grassland habitat in the western half of the great plains anywhere from texas north to south dakota and look for barren soil amongst the vegetation . clay banks near streams or in ravines and even vertical clay bluff faces are also good ( although i have not myself observed the latter ) . “my” spot is in the glass mountains of northwestern oklahoma , where talus slopes in mixed - grass prairie beneath flat - topped mesas and the ravines that cut through them provide just enough slope for this species’ liking .
step 2 . look for large , almost perfectly round burrow entrances that go straight down from the surface . by large , i mean approximately 6–8 mm in diameter—as large a burrow as any tiger beetle in north america will make . many other insects create burrows , but tiger beetle burrows are generally recognizable by their almost perfectly circular shape and clean , beveled edge . look closely , and the burrow will be seen to actually be slightly d - shaped to match the shape of the tiger beetle larva’s head—the large , sickle - shaped , upward - facing jaws resting against the flat part of the d . in the case of this species , they tend to be found in clusters of several burrows in close proximity to each other . the burrow in these photos was found at the upper edge of a drainage ravine on the upper part of the talus slopes ( see diagram in this post ) .
dig around the burrow , carefully excavating along the grass stem , until the larva is reached .
step 3 . try this first—chew the end of a long , narrow grass stem ( frayed and sticky will be easier for the larva to grab hold of ) and stick it down the burrow until it hits bottom , tap lightly a few times to entice a bite , then yank ( and i mean yank ! ) the stem out . with luck , the larva will come flying out of the burrow and land somewhere on the ground in front of you . ( by the way , if you have never done this , you are missing one of the greatest treats that insect collecting has to offer . if you have done it , you owe it to yourself to show this to somebody else who has not ever seen it—their shocked reaction at the sight of the flying larva is beyond priceless ! ) larvae are not always in the mood to bite , however , so if the so - called “fishing” technique does not work then you will have to dig . stick the grass stem back down the burrow and begin excavating around the burrow , carefully prying away the soil adjacent to the burrow to prevent it from falling into and obscuring the burrow . keep excavating as you follow the grass stem down until , at least , you reach the larva . in the photo above you can see in the lower right - center area the burrow with the grass stem protruding from it and the larva placed on a clump of soil in front of the shovel ( for sense of scale ) . it seems i had an easy time of it with this larva , as literature sources report larval burrows extending down to depths of a meter or more .
step 4 . behold the beast ! there is nothing more that can be said—these larvae are ginormous ! this particular larva measured a full 62 mm from the tips of its mandibles to the tip of its abdomen—that’s 2½ inches ! no other tiger beetle larva in north america reaches this size , except perhaps the related a . hoversoni ( south texas giant tiger beetle ) .

ted , this was a great post . i’m a tiger beetle nut too and even reared a few when i was younger . but i’d love to see them snagged out of the burrow , as you described . that sounds too fun and hopefully , sometime i’ll get to a habitat where this species occurs and have the opp to try and fish for them… thanks for sharing .
fishing for larvae ? it sounds like the pilot episode for a new television series .
great post . i enjoyed your level of detail and accompanying photos . i feel compelled to go scout some omus and do some grass fishing .
yes , hemolymph . i knicked it while digging – wasn’t sure if i’d find another one so took the photos before pickling it . fortunately i was able to dig up another one w / o injury and am trying to rear it to adulthood .
just a large “critter carrier” filled with native soil to a depth of ~ 8 inches . i don’t know if it will work or not – i’ve already got another larva collected as a 2nd instar in 2009 that has made it to 3rd instar but spends months at a time with the burrow plugged . when it does open the burrow it is ravenous !
they sure look like they would be ! i wonder how long the species spends as a larva ? at that size , i would guess at least 4 years , maybe more . it would be cool if the 2009 one would emerge as an adult one of these days .
what a great idea for a post ! i’d love to do one in any way related to a . schwarzi once i stumble upon the first habitat . at the bean museum in utah , i recall seeing many specimens… i’m regreting not writing down their localites as it is one of the more uncommon species .
what an interesting blog ! tiger beetle larvae are truly bizarre . i saw them in costa rica ( monteverde reserve ) in an almost vertical sandy slope along a dirt road . their heads were in the holes , which lacked the beveled edges of this one . the heads were flat against the surface and almost invisible with the flatness of the heads and the dirt on them . it was night . we dug one out to see the whole larva and the hump and hooks . they are so vicious . i wonder what they can catch to eat on a vertical area . did your larvae ever pupate ? what does it look like ? did the adults emerge and how long did it take ? i was interested in the comments above that a tiger beetle larva might take 2 or more years to mature and that they plug their holes for long periods , even months . i was also interested in what you said about amblychelia cylindriformis adults making burrows . i had never heard before that adult tiger beetles make burrows . what do adult burrows look like ? i wish we had tried the bite - grab - yank technique on the ones in costa rica !
hi lauren . i ended up pickling the 2012 larvae , but the 2009 larva ended up pupating last year—unbeknownst to me , as the burrow stayed plugged all summer long . i figured it had died and set the container aside , but this spring a beautiful , fully - formed adult emerged—nearly four years after i collected it as a 2nd - instar larva !
lots of adult tiger beetles make burrows , especially those that live in sandy habitats ( see my post on cicindela arenicola for an example ) . this is the first “clay” species that i’ve seen doing it , and because of their large size the burrows are also quite large , with ragged openings that look nothing like the perfectly - shaped larval burrows .

the siberian tiger ( panthera tigris altaica ) , also called amur tiger , is a tiger subspecies inhabiting mainly the sikhote alin mountain region with a small population in southwest primorye province in the russian far east .

the siberian tiger once ranged throughout all of korea , north-eastern china , russian far east , and eastern mongolia .

in 2005 , there were 331 – 393 adult and subadult siberian tigers in this region , with a breeding adult population of about 250 individuals .

the population had been stable for more than a decade due to intensive conservation efforts , but partial surveys conducted after 2005 indicate that the russian tiger population was declining .

an initial census held in 2015 indicated that the siberian tiger population had increased to 480 – 540 individuals in the russian far east , including 100 cubs .

this was followed up by a more detailed census which revealed there was a total population of 562 wild siberian tigers in russia .

this tiger subspecies was also called korean tiger , manchurian tiger , and ussurian tiger , depending on the region where individuals were observed .

the siberian tiger and bengal tiger subspecies rank among the biggest living cats .

a comparison of data on body weights of siberian tigers indicates that up to the first half of the 20th century both males and females were on average heavier than post-1970 ones .

today 's wild siberian tigers are smaller than bengal tigers .

their reduced weight as compared to historical siberian tigers may be due to a combination of causes : when captured , they were usually sick or injured and involved in a conflict situation with people .

in terms of average adult weights , a male siberian tiger rivals a male asiatic lion ( 175 kg ( 386 lb ) ) .

results of a phylogeographic study comparing mitochondrial dna from caspian tigers and living tiger subspecies indicate that the common ancestor of the amur and caspian tigers colonized central asia from eastern china , via the gansu − silk road corridor , and then subsequently traversed siberia eastward to establish the amur tiger population in the russian far east .

together , the tigers of the far east , central asia and caucasus formed the northernmost group of tigers in mainland asia .

siberian tigers are considered to be polygamous . reproduction periods and birth giving are not confined to certain season . nevertheless , the siberian tigers usually produce offspring in april – june .
the siberian tiger is solitary and nocturnal . it is among those territorial animals that can be aggressive while meeting an intruder trespassing their territory marked by scent traces . despite its unfavorable reputation , the siberian tiger doesn’t attack people , it avoids them , unless it’s very hungry or sick and can’t hunt its usual prey . the bengal tiger ( panthera tigris tigris ) is more dangerous , although the siberian tiger is larger .
the siberian tiger ( panthera tigris altaica ) is found mainly in russian territory , in the east of siberia and north china .
the siberian tiger or amur tiger is the largest subspecies and the largest cat in the world . however , this has only happened with specimens in captivity as in the wild the bengal tiger is bigger .
the siberian tiger has a few other common names including the amur tiger and the king of taiga . there are only about 500 of these animals left in the world .
in fact , the siberian tiger should be titled as the king of animals , because the lion would be defeated in such a fight – more : lion vs tiger .

a seven - year - old tiger gave birth to a female cub on 25 july 2011 , which was the first successful breeding of a siberian tiger in the wild in china .
thanks to its coloration , the siberian tiger can easily hide in grass and on trees . if there is harmony in a given ecosystem , the tiger willingly hunts elks and boars .
in 1947 the siberian tiger was taken under protection and tiger hunting was fully prohibited . the siberian tiger is enlisted in the iucn red list of threatened species , the red book of russia as endangered species and listed in appendices ii of the convention on international trade in endangered species of wild fauna and flora ( cites ) .
the siberian tiger has particularly narrow black stripes on its rusty - coloured coat . in proportion to the rest of its strong , majestic body , the legs of the siberian appear short . however , they are very strong and well - developed .
the siberian tiger is at risk of extinction , despite many actions taken in order to protect it . the animal is hunted by poachers who want its fur . also the doctors specializing in traditional chinese medicine contribute to the killings of siberian tigers .

body size and morphology varies considerably among subspecies of tigers . siberian tigers , also know as amur tigers (
siberian tigers and amur leopards mainly live in east russia , northeast china and mountainous areas in north korea .
the siberian tiger is larger than the bengal tiger ; its pelage is thicker and brighter . reddish body covered with narrow black transverse stripes . pattern of every tiger is unique , as fingerprints : you won’t find two tigers with identic pattern .
the striped pattern of the siberian tiger is unique . it is like human fingerprints . no two individuals have the same pattern of stripes on their body .
the tragic incident began when a young woman got out of a car inside the siberian tiger enclosure to berate her partner in the driver ' s seat .
human impacts have since caused the extinction of three subspecies , the javan tiger , bali tiger and caspian tiger , and world tiger numbers could now have fallen to fewer than 3000 .
this is the most common subspecies of tiger and is almost as large as the siberian tiger . fewer than 2 , 500 bengal tigers remain in their native habitat of india , nepal , and pakistan .
as people continue to encroach on the tiger ' s original range , the siberian tiger finds more people and less prey . these tigers eat wild boar , sika deer and elk . as the forest is turned into farmland or urban centers , the tiger no longer has enough food to support itself . combined with poaching of its prey species , the siberian tiger may not have enough prey to subsist on .

the provincial forestry department set up about 1 , 000 far infrared cameras to monitor the activity of the siberian tigers and leopards since 2006 . there are 27 siberian tigers currently living in jilin province , according to the latest survey .
in buddhism , the tiger symbolizes anger . the tungus peoples , currently located in siberia , regard the siberian tiger as being close to a deity . this subspecies is the national animal of south korea , while the bengal tiger is from india and bangladesh .
the amur tiger , or siberian tiger as it is also known , is the largest subspecies which once lived across a large portion of northern china , the korean peninsula , and the southernmost regions of far east russia . the amur tiger most likely derived from the caspian tiger , recent research has shown .
siberian tigers are among the world ' s most endangered species . they mostly live in northeast china and eastern russia .
china is committed to next year conducting a similar census of siberian tigers on its territory , for the first time .
because of their size , strength and ferocity , the siberian tigers have no known wild predators in their dwelling regions .

despite the aforementioned numbers , tigers are long and lean . the average head and body length of an adult siberian tiger is approximately 10 . 75 feet . the adult male tiger’s lithe body can measure as long as 3 . 7 meters , or 12 feet . female siberian tigers grow to 2 . 4 meters , or nearly 8 feet , in length . the tail length of ranges between two and three feet , and the tiger stands roughly 3 . 5 feet tall at the shoulder . for comparison , the sumatran tiger is just over half of the size of the average siberian tiger .

siberian tiger 297 print is one in a series of 10 prints which make up his endangered species portfolio . the portfolio includes the african elephant , the pine barrens tree frog , the bald eagle , the giant panda , the siberian tiger , the san francisco silverspot , the orangutan , grevy’s zebra , the black rhinoceros and the bighorn ram .
habitat the siberian tiger favours forested areas and secluded mountain ranges . in its natural habitat in the russian far east , the siberian tiger enjoys a variety of different forests , from korean pine broadleaf forests to east asian coniferous areas and a vast variety in - between . this habitat is important as it is home to the ideal types of prey required by the siberian tiger to survive . in addition to the russian far east , a small number of this subspecies can also be found in china and north korea . snow - laden areas are not suitable for the siberian tiger as their natural prey cannot survive under these conditions , meaning that there is no food for the wild cats either .
other researchers have observed bears following tiger tracks to scavenge tiger kills and to potentially prey on tigers .

intimate photos of rare siberian tigers in the remote russian far east have been released by the land of the leopard national park .
there are estimated to be about 22 adult siberian tigers and seven cubs in the park , which spans 260 , 000 hectares .
the cameras were set up by rangers in the park to monitor the tigers and equally endangered leopards , the siberian times reported .
blog dedicated to the world largest cat spacey . here you ' ll learn everything you ever wanted to know about siberian tigers .
in the feline world , the tiger reigns as the largest of cats . there are currently only five of the original nine subspecies of tigers remaining in the wild today . the sumatran tiger is the smallest of these subspecies , and the superlative honor of the largest is conferred to russia’s siberian tiger , also known as the amur tiger .
conservationists said the video footage of a mother siberian tiger and her two cubs playing 30km from the russian border was a sign the endangered species could be making a comeback in china .
normally , in the wild , the life span of a siberian tiger is 10 - 15 years , however , in captivity , they can live for up to almost 20 years .

if you have ever fantasized about a tiger purring away on your lap on a cold winter’s evening , this figure will be sobering as you ponder the consequence of being squashed . as the largest of the tigers , the average weight for an adult siberian tiger is approximately 660 pounds . a male siberian tiger can weigh in as high as 423 kilograms , or 933 pounds . females , although considerably lighter , can tip the scales at 168 kilograms , or 370 pounds . that is a massive jump from the 1 . 7 to 3 . 5 - pound weight of a newborn siberian tiger cub .
the siberian tiger may be doomed because of its lack of genetic diversity . while these tigers have made a great comeback , the huge decrease in the 1940s means that these tigers have a very limited gene pool . the cats may be inbreeding , thus causing serious health problems that may doom the subspecies . the siberian tiger is very close genetically to already extinct tigers .
males of the largest subspecies , the amur ( siberian ) tiger , may weigh up to 660 pounds . for males of the smallest subspecies—the sumatran tiger—upper range is at around 310 pounds . within each subspecies , males are heavier than females .
siberian tigers are considered endangered by iucn’s red list . one cause of their dwindling population is loss of habitat due to deforestation . in addition , siberian tigers are poached , or illegally hunted , for their fur and for body parts that are used for traditional medicines .
artificially - bred ' next generation ' siberian tigers will breed in the wild , said the park ' s chief engineer liu dan .
they were about 3 kilometers from their village , talking about how they were going to enjoy the game , when a wild siberian tiger appeared behind them , just a few dozen meters away .
the siberian tiger’s ability to devour almost 100 pounds of meat at one sitting and hold their food helps them derive energy even when winter season lasts for months , and they can survive normally .
the siberian tiger has a tremendous physical strength and greatly developed sense organs . tigers spent a lot of time hunting . their main prey – hoofed animals . to catch prey tiger creeps upon it , humps the back , sets his rear legs against the ground and attacks . only one of ten attempts succeeds . if the attempt fails tiger prefers not to follow the prey but to search for a new one . when there’s not enough prey in forests the siberian tiger can attack cattle and dogs .
many people believe that lions weigh more than tigers . but this myth is actually wrong . because tigers are the ones which weigh more than lions . . very surprisingly , the male tiger out - weighs the male lion with a factor of nearly 100 pounds . these statistics are specifically true for the siberian tigers . siberian amur tiger weighs nearly 100 pounds more than a male african lion .
heilongjiang has bred more than 1 , 000 siberian tigers since its establishment in 1986 , when it had just eight of the large cats .
the amur tiger ( panthera tigris ssp . altaica ) , also known as the siberian tiger , is among the world’s rarest and most endangered cat species . the largest and northernmost tiger , it is believed only around 450 of these magnificent , 200kg , three - metre - long cats remain in the wild .
since the start of the 20th century , when world tiger populations were thought to be above 100 , 000 , three tiger sub - species have gone extinct : the caspian tiger ( which was so closely related to the amur tiger than some scientists believe them to be one and the same ) , the bali tiger , and the javan tiger .
siberian tiger is a subspecies of tiger known by the scientific name panthera tigris altaica . it is also commonly known as the amur tiger and is the largest tiger of all . their fur possesses the ability to change shades to help with camouflage . because of the high poaching rate of these tigers , they nearly went extinct in the 1940s with only about 40 of them left , but thanks to wwf ( world wide fund for nature ) and other conservation groups , the number of siberian tigers is kept around 400 .
the views expressed in the comments above are those of our readers . ' siberian times ' reserves the right to pre - moderate some comments .
sexual maturity occurs for females after three to four years and for males , it occurs after 4 to 5 years . half of the siberian tiger cubs can not survive more than two years of age .
the largest of all cats in the world is the siberian tiger or amur tiger . they are well known for their elegant walk and their purring sound . they are often found in books , movies , and various types of folklore . this is a type of tiger that many people are familiar with the appearance of .
) reserve that has been a stronghold for the amur tiger since its creation in 1935 , and which harbors over 30 tigers today . in 1992 wcs ( initially as the hornocker wildlife institute ) in cooperation with the sikhote - alin reserve began intensive studies of tiger ecology under the siberian tiger project , today the world’s longest running radio - telemetry based tiger research and conservation effort .
the siberian tiger , a subspecies of tiger , is the largest cat in the world . it averages about 3 . 3 m ( 11 ft . ) in length , with a tail measuring 1 m ( 3 ft . ) . adult male siberian tigers can weigh up to 320 kg ( 700 lb . ) , while females are significantly smaller , weighing up to 180 kg ( 400 lb . ) .
in short , you can say about the bengal tiger that it has a nasty character . it feels an overwhelming need of confrontation , and it has been observed many times , as a tiger caused fights with lions or siberian ( amur ) tigers in in zoos .
) , though smaller than siberian tigers in body size at 2 . 85 meters in length and 195 kg , have the longest skull of all tiger subspecies , measuring 319 to 365 mm . sumatran tigers (

jilin has banned commercial logging in key state - owned forest farms since april 1 this year , which improves the living environment for the siberian tigers .
however , siberian tigers have been frequently seen around china - russia border areas in recent years , due to joint protection efforts made by both countries .
with the decrease in the population of the siberian tiger , the population of the gray wolf increases . it has been proved by the stories of local inhabitants who claim that wolves haven’t been seen in sikhote alin before ; everything changed in 1930s , when the siberian tiger started being hunted , and its habitats were occupied by the colonization of those regions at the end of 19 th and the beginning of 20 th centuries .
one average siberian tigers kill about one person a year . many of them are trappers who approached to close to the tigers . unprovoked attacks by man - eaters occur about once every four years . provoked attacks are much more common . many of the victims are unsuccessful tiger poachers . dogs and livestock are frequently taken by siberian tigers . this occurs often enough that the government compensates people who lose animal to tiger attacks .
this month marks the one year anniversary of the biggest siberian tiger release in history . four of the five amur ( aka siberian ) tigers released last year in the russian far east have adapted successfully to life in the wild . newly released video captured by a camera trap positioned at the khingan nature reserve shows a healthy tigress , ilona , marking her territory .
historically , the average adult weight was 474 pounds for males and 300 pounds for females . in short , a siberian tiger can weigh up to 660 pounds , but one specimen raised in captivity reached 1025 lbs .
russia outlawed killing the siberian tiger in 1947 , but it hasn ' t stopped poachers . siberian tigers live in such remote locations that poachers can kill them without being caught . poachers hunt these tigers for the illegal wildlife market selling skins , meat and bones . they are also hunted for traditional asian medicines . local people often view tigers as threats to people and livestock and may kill a rare tiger if they see one .
breeding and living in the wild is key for the tigers to go back to the mountains , so restoring the species numbers and assisting in their survival . picture from heilongjiang siberian tiger park , china , by urltoken
an image of a gold siberian tiger is on the coat of arms and flag of primorsky krai – it is the symbol of prosperity , and draws attention to enormous variety of plants and animals of this region .
siberian tigers are found in the russian far east , korean pine , mongolian oak and near the russian border of northeast china . the siberian tigers have the most unregimented population out of all the tigers . most of the siberian tigers that roam free in the primorsky and khabarovsky krai , located in far east russia . a couple can be found on the northeast china border . they usually live in woodlands , boreal and temperate mixed areas , or the mountains . the siberian tiger distribution area was a lot larger before they became endangered . therefore , today most of the siberian tigers are held in reservations or zoos . [ 6 ] like all tigers , the siberian tiger is very territorial . male cubs leave their mother anywhere from 16 to 22 months , whereas , the daughter may remain with her mother . sometimes it takes a one hundred kilometer journey for a tiger to find an uninhabited land to claim . a siberian tiger’s territory does not stay stable for long despite the fact that they do not migrate . it may gain territory when its neighbor dies or lose territory if it losing a fight against an invader . [ 7 ] tigers need a territory large enough to provide for their nutrition needs . they siberian tigers main prey is elk , wild boar , and sika deer . their diet also consists of smaller animals like badgers and raccoons . during the summer time , they might even feed on black and brown bears . when the times are too difficult to find their usual prey , the siberian tiger may feed upon domestic animals like dogs , cows , horses , etc . when hunting the tigers’ size , strength , and claws help them with their defense . they are extremely silent when hunting and prefer to do it alone . like all tigers , the siberian tiger will take extreme measures , such as fighting to the death , to protect their habitat , territory and young . [ 8 ]
the largest of the tiger subspecies , males can be as long as a station wagon ! these tigers also have the palest orange coat and the fewest stripes , to help it blend in with its snow - covered habitat . as it lives in a very cold climate , the siberian tiger’s coat grows longer and thicker than other tiger subspecies , and it develops a layer of fat for insulation . there are less than 400 siberian tigers left in their home range of eastern russia and northeastern china .
the gestation period in siberian tigers is 3 - 3 . 5 months . female tigers give birth once every two years at any point during the year .
history records that , during the russian civil war , both the red army and the white army based in vladivostok almost wiped out the local siberian tigers .
tiger cubs growth rate specifically depends upon their weights . at the time of their birth tiger cubs are around 1 . 8 pounds . after 120 days tiger cubs are around 35 pounds . after 60 days tiger cubs are around 9 . 5 pounds .
unfortunately , the siberian tiger has faced difficult times , full of threats derived mainly from human activities . the international union for conservation of nature ( iucn ) has classified the siberian tiger as endangered , but in the 1990s it was critically endangered . one of its worst times was in the early twentieth century since in the 1930’s the population fell to about 20 - 30 individuals . a 2005 census estimated a small population of 360 specimens .
the siberian tiger can down an asian black bear ( ursus thibetanus ) and a brown bear ( ursus arctos ) , if the population of ungulates decreases . however , in such a situation , it more often attacks brown bears near their winter habitats . the siberian tiger is more willing to hunt the bears because they cannot climb trees , contrary to asian black bears , and they prefer more open spaces where they are easier to hunt .
the siberian tiger was once found all over far east russia , the korean peninsula , and northern china . however , many people hunted these animals not only for the meat , but also their fur for clothing , medicine , and home décor . this drove these tigers almost to extinction . by the 1940s only about 40 siberian tigers were left in the wild . the first country to pass a law that gave these tigers full protection was russia . since a majority of the siberian tigers lived ( and still live ) in russia , by the 1980s there were around 500 of them . when the soviet union fell , the poaching of these tigers grew , but the russian conservation efforts , along with the wwf , have attempted to stabilize the population , keeping the number now around 450 . the siberian tigers’ habitat is limited to the primorski and khabarovski provinces of far east russian and tiny areas of the chinese border . [ 9 ] the biggest threat to siberian tigers is deforestation . a couple other main threats are the excessive hunting of the tiger’s main prey , killing the animal for it body parts to be used in traditional medicines , and habitat loss , which results from fires , logging and development of cities . the wwf along with the russian animal conservation and scientist have been working on several ways to protect the siberian tigers and help the subspecies prosper . they have secured the siberian tigers’ habitats . these include protected areas and conservation leases . they have also found millions of acres that can sustainable manage the tigers . siberian tigers are also being placed into zoos and preserves where they can be watch , protected , and their reproduction can be managed . people are also working with hunting communities to protect the animals like deer , elk , and boar that the siberian tiger hunts . the wwf is trying to create better logging and hunting laws that will be reinforced to protect the tigers’ habitats . they also advocate the importance of saving the siberian tiger to people . they help host an annual “tiger day” in vladivostok and other cities in the primorskii provinces , where the siberian tiger population is high . [ 10 ]
siberian tigers are distinguishable by their striped fur . similar to people’s unique fingerprints , no two tigers have the same striped pattern . siberian tigers differ from other tigers because they have fewer , paler stripes , and they also have manes . the mane , in addition to their thick fur , helps keep them warm .
bengal tigers are second only to the siberian tiger in size . in fact , some bengal tigers from the indian state of assam are as large as siberian tigers . there is wide variation in their striping patterns . a specific feature of bengal tigers is their black ear . the large tiger weights around 160 - 260 kg . its ranges are in small protected areas in india , nepal , bhutan , bangladesh , and western forest of myanmar .
they ( the attacks ) were an avoidable tragedy ,
says wu zhigang , a researcher with the jilin provincial institute of forestry science and one of the foremost scholars in siberian tiger protection .
both the tiger and the farmers would have been safe if not for the snares .
size : length of the siberian tiger body , without tail – 160 - 200 cm , length of tail about 100 cm . weight of an adult animal can reach 300 kg . the largest weight recorded – 384 kg .
siberian tigers were once found throughout the russian far east , northern china and the korean peninsula . by the 1940s hunting had driven the tiger to the brink of extinction , with no more than 40 remaining in the wild .

tigers are special animals . they rule in asia . siberian tigers have really shown us any animal can survive and adapt in any climate .
environmental officials from china and russia have decided to work together to improve the protection of siberian tigers and amur leopards in order to save the two endangered species .
only 300 are believed to be living in the wild , with 20 in northeast china . siberian tigers are one of the world ' s rarest animal species .
the siberian tiger feeds on several animal species . an individual typically consumes musk deer , manchuria wapitis , gorals , moose , wild boars , siberian roe deer , sika deer , hares , rabbits , pikas and even salmon , and other species of ungulate animals . according to a study carried out in the 1990s , its distribution seems to be related to the distribution of its favorite prey .
we can save wild tigers . in 2010 , the 13 tiger range countries committed to tx2—to double wild tiger numbers by 2022 , the next year of the tiger . wwf is driving tx2 forward .
the siberian tiger is the largest of all of the wild cats in the world . also known as the amur tiger or by its scientific name , panthera tigris altaica , this magnificent animal is naturally found predominantly in the sikhote - alin mountain range in the far east of russia . of course , there are also siberian tigers in zoos , parks and conservation areas around the world . today , there are only about 400 siberians to be found in the wild .
the siberian tigers once wandered in tianqiaoling area but became extinct in the mid 1980s ,
said wu zhigang , a researcher with the provincial academy of forestry .
wwf’s conservation efforts to entice siberian tigers back to china over the last six to seven years have largely focused on bringing back the deer that the tigers prey on .

in the past , the siberian tiger was also considered to be shy and non - threatening towards people , unless it was provoked , although there were incidents when a tiger killed a woman collecting wood , and a defenseless officer when he was crossing a reed bed . we need to add the latest case , when an amur tiger killed a zoo keeper in germany .
in 1996 , the global survival network ( gsn ) was part of a multilateral effort to increase protection of the endangered siberian , or amur , tiger . the program , named the phoenix fund , was co - developed by the post

the siberian tiger , although it is more peaceful and doesn’t cause such encounters , always wins them . its size , weight , and range of arms are decisive factors . it is the largest cat and it is unrivalled among felids .
ligers are the biggest cats on earth ; they weigh 900 to 1200 pounds . siberian tigers are the second biggest cats with a weight of around 600 pounds and lions are the third biggest cats with a weight of around 500 pounds . bengal tigers and sumatran tigers also weigh more than lions even though they are smaller than siberian tigers .
there are currently an estimated 500 siberian tigers in the wild , of which only 20 or so can be found live in northeast china ' s jilin and heilongjiang provinces .
according to wwf , there are about 540 wild tigers around the world . from 2012 to 2014 at least 27 wild siberian tigers were spotted in north - east china .
fur : unlike the royal bengal tigers , the siberian tigers have dense fur and also manes , which help them stay warm in the cold snowy weather . their stripes are fewer and paler , which make them differentiable from other tiger species .
the weight of a male siberian tiger , normally about 550lb , increases by about 10 per cent in winter , mr liu said , adding that food intake for the big cats increases by about 30 per cent to 13 - 18lb daily .
the goal of the siberian tiger project is to collect the best possible scientific information on tiger ecology for use in conservation plans . through radio - tracking of more than 60 tigers since 1992 , wcs specialists have studied their social structure , land use patterns , food habits , reproduction , mortality , and relationship with other species , including humans . as a result we have consistently made sound conservation recommendations based upon comprehensive knowledge of tiger ecology and the role of tigers in the forested ecosystems of the russian far east . the siberian tiger project positions wcs as scientific leaders in russia , and gives us the credibility to engage policy - makers as scientists with a real understanding of tiger conservation needs .

tiger ( panthera tigris linnaeus , 1758 ) is a characteristic species of asia , which is in severe danger . siberian tiger ( panthera tigris altaica ) is the largest one of the five existent tiger subspecies . it is extremely endangered . one new way for tiger protection and rescue is to study interspecies cloning . but there is few research data about siberian tiger . in this study , we cultured siberian tiger fibroblasts in vitro , analyzed their biological characteristics , chromosomes , and cell cycles , to provide not only nuclear donors with good morphology , normal biological characteristics , and chromosome quantity for tiger interspecies cloning , but also reliable data for further studying siberian tiger . the results indicated that siberian tiger ear fibroblasts can be successfully obtained by tissue culture either with or without overnight cold digestion , the cultured cells were typical fibroblasts with normal morphology , growth curve , and chromosome quantity ; g0 / g1 percentage increased and s percentage decreased with the confluence of cells . g0 / g1 and s stage rate was significantly different between 40–50 % and 80–90 % , 95–100 % confluence ; there is no distinct difference between 80–90 % and 95–100 % confluence . the cells at the same density ( 80–90 % confluence ) were treated with or without 0 . 5 % serum starving , go / g1 rate of the former was higher than the latter , but the difference was not significant . go / g1 proportion of 95–100 % confluence was slightly higher than serum starving ( 80–90 % confluence ) , but no significant difference . therefore , the siberian tiger fibroblasts we cultured in vitro can be used as donor cells , and the donor cells do not need to be treated with normal serum starvation during nuclear transfer ; if we will just consider the rate of the g0 / g1 stage cells , serum starvation can be replaced by confluence inhibition when cultured cells were more than 80–90 % confluence .
the habitat of the siberian tigers is mostly the snow - covered hilly regions , where they actually belong . like all other tigers , these tigers prefer to live in the forest areas .
there have been several reports of captive tigers mauling humans in recent years . in a 2009 attack , chinese cops shot and killed two siberian tigers after they pounced on a zoo worker .
about 500 siberian or amur tigers are left in the wild , with 95 % of them in the russian far east . within the tiger’s range in russia , the largest protected area is the sikhote - alin biosphere reserve , a 400 , 000 ha ( 4000 km
size : the siberian tiger can reach a length of up to 10 feet , with the tail attaining an average length of about 3 feet . the height of these felids is 3 to 3 ½ feet ( . 9 – 1 . 1m ) at the shoulders .
a tigon is a hybrid bit cat that results from the crossbreeding of a tiger and lioness . tigons have a fur like lion and stripes like tiger .
the amur tiger is found mostly in the area of manchuria which is close to the amur river . around south central china is where you will find the south chinese tiger . the southeast of china is where you will find the indo - chinese tiger . around indonesia is the home of the sumatran tiger .
on november 21 - 24 , 2010 , st petersburg hosted the international tiger conservation forum which featured representatives of 13 countries that have wild tigers . the forum participants approved a global programme for the restoration of the tiger population and a declaration of tiger conservation . russia will enact a national amur tiger conservation strategy .
villagers in north - east china have long endured frigid winters , scorching summers and an occasional drought , but some now have something else to worry about : possible attacks by wild siberian tigers .

according to the world wildlife fund , the present population of these extremely rare mammals is 400 ( as of 2014 ) . the main cause of the rapid fall of the population of the siberian tiger is poaching . these tigers have frequently been hunted down for their skin .
siberian tigers have also been losing habitat to increasing human activity—primarily logging and road - building—as well as to changes brought about by global warming . drier , hotter conditions , along with frequent , devastating forest fires , have been a major effect of climate change on tiger habitat .

distributed from the balkan over turkey to the caucasus from 500 - 2000m , from hilly grasslands to subalpine zone .
there are several opinions on the status of this taxon , from being a subspecies of c . gardetta , a subspecies of c . leander to a species on its own . an article debating this can be found here .
a lowland species , mostly found < 500m , has declined seriously in europe . mostly found in wet grasslands , hence water management probably being one of the main reasons for the decline .
until the early nineties this species had a population in the south of belgium . changes in forest management , water level management , nitrification and maybe climate change have however induced a massive decline in the western distribution of this species so that nowadays - apart from a few populations in the very east of france - it has almost disappeared from france as well .
a species that has declined massively in nw - europe and has disappeared from belgium and parts of the netherlands and northern france . reasons for decline are probably a combination of nitrification , water level management , climate change , . . .
i have only seen it once in northern austria on a windy day so butterflies were difficult to get close by so i only have this vague picture . a variable species with lots of described local forms . the form depicted here is c . tullia tiphon .
the balkan mountain replacement of previous species and in debate if a species on its own . subalpine to alpine .
to be found in the western mediterranean area from central italy over the south of france and iberia to northwestern africa .
closely related to previous species and nowadays mostly seen as a subspecies of corsican heath . it is restricted to elba and some smaller islands but can also be found on the opposing tuscan coast where i could see the species .
species fromt the western palearctic still missing in this list are mainly far eastern species , island specialties and species from northern africa . all species i hope to see in the future . . .
