Siberian tiger

The Siberian tiger vs Bengal tiger sometimes known as the Amur tiger, is a subspecies of the tiger that is endemic to North Korea, Northeast China, and the Russian Far East. Its historical range included the all of the Korean Peninsula, but today it is primarily restricted to the Sikhote-Alin mountain range in the southwest of the Russian Far Eastern province of Primorye. Siberian tigers were present in this area in 2005 in numbers ranging from 331-393 adults and subadults, with a reproducing adult population of roughly 250 animals. Siberian tiger vs Bengal tiger due to extensive conservation efforts, the population had been constant for more than 10 years, however surveys that were only partially complete after 2005 show that the Russian tiger population was in decline. According to a preliminary census conducted in 2015, there were 480–540 Siberian tigers in the Russian Far East, including 100 cubs. A more thorough census was conducted afterward, and it turned out that there were 562 wild Siberian tigers living in Russia as a whole. In the international border region between Russia and China as of 2014, there were said to be roughly 35 people living there.
The now-extinct Caspian tiger has genetic ancestry with the Siberian tiger. The common ancestor of the Siberian and Caspian tigers colonised Central Asia from eastern China via the Gansu–Silk Road corridor, and later crossed Siberia to establish the Siberian tiger population in the Russian Far East, according to the results of a phylogeographic study comparing mitochondrial DNA from Caspian tigers and living tiger populations. The northernmost tiger populations in continental Asia were those in the Caspian and Siberian seas. Siberian tiger vs Bengal tiger the tiger from Siberia was Depending on the area in which individuals were sighted, they were also known as “Amur tiger,” “Manchurian tiger,” “Korean tiger,” and “Ussurian tiger.

The Panthera tiger subspecies, which has populations in North Korea, Northeast China, and the Russian Far East, includes the Siberian tiger, also referred to as the Amur tiger. While it once covered the whole Korean Peninsula, today’s distribution is mainly limited to the Sikhote-Alin mountain range in the southwest of the Primorye province in Russia’s Far East. In this region in 2005, there were 331-393 adults and subadults of the Siberian tiger, with a reproducing adult population of about 250 individuals. The population had been stable for more than 10 years due to strong conservation efforts, however studies that were only partially finished after 2005 indicate that the Russian tiger population was declining. an initial census performed in 2015 found that there were currently 100 cubs and 480–540 Siberian tigers residing in the Russian Far East. After that, a more complete count was made, and it was discovered that there were 562 wild Siberian tigers in all of Russia. As of 2014, it was estimated that 35 people lived in the area along the international border between Russia and China.

Siberian tiger Phylogeny

Since the 1990s, Siberian tiger vs Bengal tiger several studies on the genetics of the Siberian tiger and its connections to other populations have been released. The finding of little genetic variety in the wild population, particularly when it comes to maternal or mitochondrial DNA lineages, has been one of the most significant results. It appears that the maternal lineages of wild Siberian tigers are virtually entirely dominated by a single mtDNA haplotype. On the other hand, tigers kept in captivity seem to have more diverse mtDNA. Given that the founders of the captive population were taken while genetic variety was higher in the wild, this may indicate that the subspecies has undergone a fairly recent genetic bottleneck brought on by human pressure.
Beginning in the year 2000, researchers from the University of Tissue samples were taken from 20 of the 23 Caspian tiger specimens housed in museums around Eurasia by researchers from Oxford, the U.S. Siberian tiger vs Bengal tiger they analysed at least a portion of five mitochondrial genes and discovered that Caspian tigers’ mitochondrial DNA was less variable than that of other tiger subspecies. The Siberian tiger is the Caspian tiger’s genetically closest surviving relative, which strongly suggests a relatively recent shared ancestry. They reevaluated the evolutionary connections of tiger subspecies and discovered a surprising likeness between the two tigers. They hypothesised that the Caspian and Siberian tigers’ common progenitor entered Central Asia via the Gansu area of the Silk Road fewer than 10,000 years ago. Following a journey via eastern China, the Siberian tiger population in the Russian Far East was established. The Caspian and Siberian tigers were likely part of a single continuous population, but the Industrial Revolution’s events may have been a key role in their mutual separation.

95 wild Amur tigers were sampled across their natural habitat to answer questions about the demographics and genetic makeup of the population. In order to evaluate the genetic representation found in captivity, selected individuals from the North American ex situ population were sampled as well. In Russia, two groups that are divided by a development corridor have been clearly established by population genetic and Bayesian structural analysis. Despite their well-documented fall in the 20th century, the researchers were unable to identify any signs of a recent population bottleneck, however genetic A historical contraction’s telltale signs were found. This signal discrepancy might be caused by a number of factors, including past population genetic variation shortage brought on by postglacial immigration and probable gene flow from extinct Chinese populations. Similar levels and patterns of genetic diversity were present in both confined and wild populations, but ex situ remained gene variations that were lost in situ. Siberian tiger vs Bengal tiger Overall, their findings support a previous study that suggested the captive population may be a reservoir of gene variants lost in situ and highlight the need to maintain ecological connectivity between the two Russian populations to reduce genetic diversity loss and overall susceptibility to stochastic events.
The Siberian tiger’s whole genome was sequenced and published in 2013. mainland tigers Asia is divided into two clades: the southern clade includes all remaining continental tiger populations, while the northern clade includes the Siberian and Caspian tiger populations. A 2018 research that used whole-genome sequencing for analysis used 32 tiger specimens as its basis. According to the findings, there are six monophyletic tiger clades, and the most recent common ancestor lived around 110,000 years ago.

Siberian tiger Body size

The average weight of wild Siberian tigers was reported to be 100 to 167 kg (220 to 368 lb) for females and 180 to 306 kg (397 to 675 lb) for males in the 1980s. Hunters hunted and killed very enormous animals. An examination of historical and modern data on the body weights of wild and captive tigers, both female and male across all subspecies, was published in 2005 by a consortium of Russian, American, and Indian zoologists. The weights of tigers older than 35 months that were measured in the presence of the authors are included in the data. They found that, compared to post-1970, both male and female Siberian tigers were typically heavier in the first half of the 20th century. ones. The average wild Siberian tiger weighs 117.9 kg (260 lb) whereas the average wild male weighs 176.4 kg (389 lb), with an asymptotic limit of 222.3 kg (490 lb). Siberian tigers in the wild typically weighed between 215.3 kg (475 lb) for males and 137.5 kg (303 lb) for females. While modern Siberian tigers are typically lighter than Bengal tigers, historical Siberian tigers and Bengal tigers were the biggest. Concurrent factors, such as the decreased quantity of prey as a result of illegal hunting and the fact that the animals were typically sick or injured when seized in a struggle with humans, may be used to explain why the body weight of today’s Siberian tigers has decreased.
scientific measurements made by the Siberian Tiger Project Males in the Sikhote-Alin vary in head and body length from 178 to 208 cm (70 to 82 in), with an average 165 to 182 cm (66 to 72 in), with an average of 174 cm (69 in), and females between 167 and 182 cm (66 to 72 in). Males’ average tail length is 99 cm (39 in), while females’ average tail length is 91 cm (36 in). The longest male was 309 cm (122 in) long overall, with a tail length of 101 cm (40 in), and a chest circumference of 127 cm (50 in). The largest female was a 270 cm (110 in) overall length, with a tail that was 88 cm (35 in) long and a breast circumference of 108 cm. (43 in). The biggest male with a radio collar weighed 212 kg (467 lb), and a tiger seized by members of the Siberian Tiger Project weighed 206 kg (454 lb). The biggest tiger is frequently thought to be the Siberian.A wild male that was killed near the Sungari River in Manchuria in 1943 is said to have measured 350 cm (140 in) “over the curves” and had a tail that was approximately the same length.

Hunting and diet

The Manchurian wapiti (Cervus canadensis xanthopygus), Siberian musk deer (Moschus moschiferus), and long-tailed gorilla (Naemorhedus caudatus) are among the prey species that the tiger preys upon. Additionally, Siberian tigers eat salmon as well as smaller prey such as hares, rabbits, and pikas. Between November 2014 and April 2015, scat was collected along the international boundary between Russia and China; 115 scat samples from nine tigers comprised primarily wild boar, sika deer, and roe deer remnants.
11 tigers were kidnapped, equipped with radio collars, and tracked for more than 15 months in the eastern Himalayas between January 1992 and November 1994. the Sikhote-Alin mountain range’s slopes. The study’s findings show that while wild boar distribution was not a very good predictor of tiger distribution, their distribution is strongly related to that of Manchurian wapiti. Despite the fact that they hunt Siberian roe deer and sika deer, there was little overlap between these ungulates and tigers. The distribution of moose was not strongly correlated with that of tigers. An accurate predictor of the distribution of tigers was the distribution of important prey species’ preferred habitats. According to the findings of a three-year research on Siberian tigers, the average time between kills and estimated prey intake varied depending on the season: from 2009 to 2012, three adult tigers killed prey on average every 7.4 days in the summer and devoured an average of 7.89 kg per day. during the winter, they ingested an average of 10.3 kg (23 lb) per day and killed more large-bodied animals, making kills every 5.7 days.

Bengal tiger

Bengal tiger

The Bengal tiger is comprised of the Panthera tigris tigris subspecies of tigers and its population. It is one of the biggest wild cats that are still around. It is thought to be a charismatic megafauna member. Tigers are thought to have existed on the Indian subcontinent between 12,000 and 16,500 years ago, during the Late Pleistocene. Its current risks include poaching, habitat degradation, and fragmentation. In 2011, it was estimated that less than 2,500 wild animals remained. In its range, there are no Tiger Conservation Landscapes judged large enough to support a population of more than 250 adults. The ancient range of the Bengal tiger included practically all of India, Pakistan, and the Indus River basin until the early 19th century Bhutan, southern Nepal, Bangladesh, and western China. These days, it may be found living in India, Bangladesh, Nepal, Bhutan, and southwest China. By 2018, it was projected that there were 2,603–3,346 tigers living in India. Bangladesh is expected to have between 300 and 500 residents, 355 in Nepal by 2022, and 90 in Bhutan by 2015.

Bengal tiger Characteristics

The belly and inner portions of the limbs are white, the tail is orange with black rings, and the Bengal tiger’s coat ranges in colour from yellow to light orange with stripes that range in colour from dark brown to black. Recessive mutant white tigers are occasionally observed in the wild in Assam, Bengal, Bihar, and particularly in the old State of Rewa. Albinism does not, however, occur in this case. A real albino tiger has only ever been documented once, and there have never been any black tigers, with the probable exception of one deceased specimen inspected in Chittagong in 1846. The Natural History Museum in London’s collection has fourteen Bengal tiger skins with 21–29 stripes. The following recessive mutant is the golden tiger, which has red-brown stripes running through its light golden fur. In nature, mutants are quite uncommon. In male tigers, the greatest skull measures 351 mm (13.8 in) in length while in females, it measures 293 mm (11.5 in). It has teeth that are very thick. Its canines are the longest among all cats at 7.5 to 10 cm (3.0 to 3.9 in) length.

Body weight and size

Bengal tigers in the Panna Tiger Reserve reach head-to-body lengths of 164–193 cm (65–76 in) for females and 183-211 cm (72–83 in) for males, with a tail that can reach a length of up to 83 cm (72 in) is around 85–110 cm (33–43 in) long. Male tigers may grow to a total length of 283–311 cm (111–122 in), whereas female tigers can grow to a total length of 25–285 cm (100–112 in). Their usual shoulder height is between 90 and 110 cm (35 and 43 in).
Subadult males weigh between 80 and 100 kg (180 to 220 lb) and attain adult weights between 110 and 180 kg (240 and 400 lb), whereas subadult females weigh between 80 and 100 kg (180 to 220 lb). 42 mature male Bengal tigers weighed on in central India. In comparison, 39 adult female Bengal tigers weighed an average of 132 kg (291 lb) with a maximum of 156 kg (344 lb) and an average total length of between 239 and 277 cm (94 to 109 in), or 254 cm (100 in). Their average shoulder height was 99 cm (39 in), and their overall length ranged from 267 to 312 cm (105 to 123 in). According to some biologists, adult male Bengal tigers in the Terai regularly weigh more than 227 kg (500 lb). Early in the 1970s, seven mature males were taken in Chitwan National Park; their average weight was 235 kg (518 lb), and they ranged in size from Females ranged in weight from 116 to 164 kg (256 to 362 lb), while males ranged from 200 to 261 kg (441 to 575 lb). The two male tigers that were captured in Chitwan National Park in the 1980s were the biggest free-ranging tigers ever recorded, weighing more than 270 kg (600 lb).
Adult female Bengal tigers from the Bangladesh Sundarbans had the least known weights at 75 to 80 kg (165 to 176 lb). The average weight of three tigresses from the Bangladeshi Sundarbans was 76.7 kg (169 lb). The eldest female was captured weighing 75 kg (165 lb) and in quite bad shape. Their body weights and skull shapes were different from those of tigers in other settings, suggesting that they could have modified their behaviour to cope with the particular challenges of the mangrove ecosystem. Due to severe intraspecific rivalry and the smaller prey accessible to tigers in the Sundarbans than the bigger deer and other prey available to tigers in other areas, their diminutive sizes are most likely a result of these factors.
Shot in 1860 at Mussoorie, the enormous “Leeds Tiger” on exhibit at Leeds City Museum had a body length of 371 cm (12 ft 2 in) at the time of death. According to reports, two tigers killed towards the end of the 19th century in Kumaon District and close to Oude measured larger than 370 cm (12 feet). However, athletes at the time had not yet embraced a common method of measuring; some measured whereas others measured “over the curves,” or “between the pegs.” The largest tiger skull ever found measured 413 mm (16.25 in) “over the bone” and was killed in the area of Nagina in northern India.
A male tiger with a head and body length of 221 cm (87 in) between pegs, a chest circumference of 150 cm (59 in), a shoulder height of 109 cm (43 in), and a tail length of 81 cm (32 in) was shot in central India around the turn of the 20th century. The tail was likely bit off by a competitor male. It was not possible to weigh this specimen, although it was assumed to weigh roughly 272 kg (600 lb). The victim was a guy who weighed 259 kg (570 lb). the 1930s in northern India. A male tiger killed in Nepal measured 328 cm (10 ft 9 in) “over the curves” and weighed 320 kg (710 lb). Undoubtedly, a large male tiger slain in 1967 near the foothills of the Himalayas was the heaviest wild tiger ever recorded. After consuming a buffalo calf, it weighed 388.7 kg (857 lb) and had a total length between pegs and curves of 323 cm (127 in) and 338 cm (133 in). The calf would have weighed at least 324.3 kg (715 lb) if it hadn’t been eaten earlier. The Smithsonian Institution’s Mammals Hall currently has this specimen on display. A male tiger shot in India’s Central Provinces weighed 317 kg (699 lb) and stood 3.02 m (9 ft 11 in) tall.

Bengal tiger

Tiger (Panthera) subspecies that live in the marshes and forests of India, Bangladesh, Bhutan, and Nepal. The orange coat of the Bengal tiger, highlighted by distinct brownish-to-black stripes, sets it apart from other tiger subspecies. There is also a very rare white-coated Bengal tiger subspecies. Most experts believe the Bengal tiger to be the second largest tiger in the world, second only to the Siberian tiger in terms of size. While just 2,000 to 2,500 are still living in the wild, it is believed that many more live in zoos and private reserves around the world.

The greatest male Bengal tigers can reach lengths of up to 3.2 meters (10.5 feet) and weights of over 295 kg. They also have a 1-meter (3.3-foot) long tail 650 pounds or such. The largest females are smaller and can reach lengths of up to 2.7 meters (9 feet) and weights of up to 181 kg (400 pounds). Wild boars (Sus scrofa), gaurs, and ungulates (such as deer and antelope) are their main prey items. They are lone hunters. However, Bengal tigers often kill and devour a number of humans in Bangladesh and India after they come into contact with them.

Bengal tiger Distribution and habitat

In a prehistoric midden near Kuruwita in Sri Lanka, a sub-fossil right middle phalanx dating to around 16,500 years ago that is tentatively thought to be from a tiger was discovered in 1982. Prior to the last glacial maximum, which occurred around 20,000 years ago, the tiger population in Sri Lanka appears to have arrived during a pluvial era when sea levels were low. To colonise Sri Lanka, which had previously been connected to India by a land bridge, the tiger likely arrived in southern India too late.
The area in the Chittagong Hills and Brahmaputra River basin, bordering the Indian subcontinent, is thought to be the historical northeastern geographical limit of the Bengal tiger, according on results of a phylogeographic research utilising 134 samples from tigers throughout their worldwide range. range of the Indochinese tiger historically. Tigers live in a variety of habitats in the Indian subcontinent, including mangroves, subtropical and temperate highland forests, tropical wet evergreen forests, tropical dry forests, tropical and subtropical moist deciduous forests, and alluvial grasslands. The latter habitat, which formerly stretched across a sizable area of grassland, riverine habitat, and wet semi-deciduous forests along the Gangetic and Brahmaputra plains’ major river systems, has mostly been turned over to agriculture or has been badly degraded. Only a few number of blocks near the base of the outer foothills of the Himalayas have the largest examples of this habitat type today, including the transboundary Tiger Conservation Units (TCUs) Chitwan-Parsa-Valmiki, Dudhwa-Kailali, and Shuklaphanta-Kishanpur. These TCUs have high tiger concentrations in part because to the exceptional prey ungulate biomass. By the late 19th century, Khairpur in Pakistan was the tiger’s last refuge; the last animals were killed at Bahawalpur, in the Indus Riverine Jungles, in 1906.

Bengal tiger size comparison

A male Siberian Tiger can weigh up to 660 pounds, whereas the normal Bengal tiger weighs between 200 and 400 pounds. In general, the Bengal tiger is smaller and lighter than the Siberian, reaching a maximum length of 8 feet as opposed to the Siberian Tiger’s 10 feet.

amur tiger vs bengal tiger

East Russia, Korea, and northern China are home to birch and coniferous forest zones where Siberian tigers, often referred to as Amur tigers, can be found. Siberian tigers have thick, pale golden fur, while Bengal tigers have thin, light yellow fur. Siberian tigers occasionally also have rusty red fur.
