The asiatic lion

0

The Asian Lion is a Panthera Leo population of India. Its present range is limited to the Gir National Park and the surrounding areas in the Indian state of Gujarat. India Historically, it inhabited many parts of West Asia and the Middle East, from northern India. Under the IUCN Red List, its ancient scientific name, Panthera leo persica, is threatened with extinction due to its small population and population.

The first scientific description of the Asian lion was published in 1826 by the Austrian zoologist Johann N. Published by Meyer and named Felice Leo Perseus. Until the nineteenth century, it took place in eastern Turkey in Turkey, Iran, Mesopotamia, and the East of the Indus River in Bengal and the Narmada River in central India. Since the beginning of the twentieth century, it has been confined to the Gir Forest National Park and surrounding areas. This lion population has been steadily rising since 2010. In May 2015, the 14th Asian Lions Census was conducted over an area of ​​20,000 square kilometers (7,700 square miles); The lion population is estimated at 523, with 109 adult males, 201 adult females, and 213 cubs. In August 2017, surveyors counted 650 wild lions. The 15th Asian Lion Census could not be held in 2020 due to the COVID-19 epidemic. An estimated exercise in June 2020 counted 674 Asian lions in the Gir forest region, a 29 percent increase over the 2015 census.

Fossil fossils of Panthera spelia excavated at the Chromer platform indicate that it represents a genetically isolated and highly diverse lineage not closely related to Asian lions. Fossil lion remains have been found in Pleistocene deposits in West Bengal. Fossil excavations at Batadomba Cave show that Panthera leo sinhalius lived in Sri Lanka at the end of the Pleistocene and is thought to have become extinct about 39,000 years ago. In 1939, Deraniyagala explained that this lion was different from the current lion.


Lion Physics

The results of a phylogeographic analysis based on the MTDNA sequence of lions around the world, including an extinct population such as the Barbary Lions, show that sub-Saharan African lions are physically basal to all modern lions. These findings are supported by a center in East and South Africa of African origin in the Eastern Lion Evolution. During the last 20,000 years, lions may have migrated to West Africa, East North Africa, and the Arabian Peninsula to Turkey, Southern Europe, and northern India. The Sahara, tropical rainforests, and the Great Rift Valley are natural barriers to lion dispersal.

An ancient study of the genetic markers of 357 samples from captive and wild lions in Africa and India, including an endangered population, was examined in a study on lion evolution. The results show four lineages of lion population: one in Central and North Africa, one in Asia, one in Kenya, one in South Africa, and one in South and East Africa. It has been suggested that the first wave of lion expansion from East Africa to West Asia occurred about 118,000 years ago and that the second wave occurred during the late Pleistocene or the Holocene period from South Africa to East Africa.

The Asian lion is genetically closer to the North and West African lions than the group of East and South African lions. These two groups diverged about 186,000–128,000 years ago. The Asian lion is believed to have been associated with North and Central African lions until the extinction of lions in Western Eurasia and the Middle East during the Holocene disrupted genetic flow.

Asian lions are genetically less diverse than African lions, which may be a consequence of an early impact on the recent history of the remaining Gir forest population.

characteristics

An Asian lion

The fur of the Asian lion ranges from rough-dark to dark-black, sandy or gray, and sometimes some lamps have a silver coating. Males have only a moderate growth on the top of the head, then their ears are always visible. The cheeks and throat are very small, measuring only 10 cm (3.9 inches) in length. Infrared foramina divide about half of the skulls of Asian lions in the Gir forest, while African lions have one foramen on either side. The sagittal logo is more strongly developed and the posterior orbital region is shorter than that of the African lion. The skull length of adult males is approx. 330 to 340 (13 to 13 inches) and 292 to 302 mm (11.5 to 11.9 inches) for women. It differs from the African lion in having a larger tail and a lower-quoted auditory bullet. The most striking morphological feature of the Asian lion is the durable nature of the skin that runs along the abdomen.


The shoulder height of males is 107–120 cm (3.51–3.94 ft) and that of females is 80–107 cm (2.62–3.51 ft). The head and body measurements of two lions in the Gir Forest were 1.98 m (78 in), with a tail length of 0.79–0.89 (31–35 in) and a total length of 2.82–2.87 (111–113 in), respectively. The Gir lion is similar to the Central African lion and smaller than the larger African lions. Adult males weigh 160 to 190 kg (350 to 420 lb) and females weigh 110 to 120 kg (240 to 260 lb).

Manes

Asian (upper) and South African (lower) lions. Note the large tail, the sparse mane on the head, and the prominent folds of skin on the front abdomen

The color and growth of male lions' minds vary by region, population, and age of the lion. In general, the Asian lion differs in a less developed dimension than the African lion. Less developed and does not extend below the abdomen, sides, or ulna. Lions with such small manes were also known in the Syrian region, the Arabian Peninsula, and Egypt.

In contrast, Nineveh's rock relief in the Mesopotamian plain represents a lion with short hair. Therefore, it is suspected that the Mesopotamian lion may have been a special subspecies, and Panthera Leo suggested a scientific name for it, Mesopotamia.

Lions of exceptional size

The record length of a male Indian lion is 2.92 meters (115 inches), including the tail.
