The tiger is a member of the genus Panthera and the largest living cat species native to Asia. It has a powerful, muscular body with a large head and paws, a long tail and orange fur with black, mostly vertical stripes. It is traditionally classified into nine recent subspecies, though some recognise only two subspecies, mainland Asian tigers and the island tigers of the Sunda Islands.
Palawan is the largest island of the province of Palawan in the Philippines and fifth-largest by area and tenth-most populous island of the country, with a total population of 994,101 as of 2020 census. The northwest coast of the island is along the Palawan Passage in the eastern South China Sea, while the southeast coast forms part of the northern limit of the Sulu Sea. Much of the island remains traditional and is considered by some as under-developed. Abundant wildlife, jungle mountains, and some white sandy beaches attract many tourists, as well as international companies looking for development opportunities.
The American lion, with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 130,000 to 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion, with the American lion representing an offshoot from the lineage of the largely Eurasian cave lion, from which it is suggested to have split around 165,000 years ago. Its fossils have been found across North America, from Canada to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids to ever exist, and an important apex predator.
The Indochinese tiger is a population of the Panthera tigris tigris subspecies that is native to Southeast Asia. This population occurs in Myanmar and Thailand. In 2011, the population was thought to comprise 342 individuals, including 85 in Myanmar and 20 in Vietnam, with the largest population unit surviving in Thailand, estimated at 189 to 252 individuals during the period 2009 to 2014.
The Sumatran tiger is a population of Panthera tigris sondaica on the Indonesian island of Sumatra. It is the only surviving tiger population in the Sunda Islands, where the Bali and Javan tigers are extinct.
The Caspian tiger was a Panthera tigris tigris population native to eastern Turkey, northern Iran, Mesopotamia, the Caucasus around the Caspian Sea, Central Asia to northern Afghanistan and the Xinjiang region in western China. Until the Middle Ages, it was also present in southern Russia. It inhabited sparse forests and riverine corridors in this region until the 1970s. This population was regarded as a distinct subspecies and assessed as extinct in 2003.
The Javan tiger was a Panthera tigris sondaica population native to the Indonesian island of Java. It was one of the three tiger populations that colonized the Sunda Islands during the last glacial period 110,000–12,000 years ago. It used to inhabit most of Java, but its natural habitat decreased continuously due to conversion for agricultural land use and infrastructure. By 1940, it had retreated to remote montane and forested areas. Since no evidence of a Javan tiger was found during several studies in the 1980s and 1990s, it was assessed as being extinct in 2008.
The Malayan tiger is a tiger from a specific population of the Panthera tigris tigris subspecies that is native to Peninsular Malaysia. This population inhabits the southern and central parts of the Malay Peninsula, and has been classified as critically endangered. As of April 2014, the population was estimated at 80–120 mature individuals, with a continuing downward trend.
Niah National Park, located within Miri Division, Sarawak, Malaysia, is the site of the Niah Caves which are an archeological site.
Panthera tigris trinilensis, known as the Trinil tiger, is an extinct tiger subspecies dating from about 1.2 million years ago that was found at the locality of Trinil, Java, Indonesia. The fossil remains are now stored in the Dubois Collection of the National Museum of Natural History in Leiden, the Netherlands. Although these fossils have been found on Java, the Trinil tiger is probably not a direct ancestor of the Javan tiger. The Trinil tiger probably became extinct 50,000 years ago. The Bali tiger was also not closely related to the Trinil because of their time differences.
The Balabac Strait is one of the straits that connects the South China Sea with the Sulu Sea. It separates Balabac Island, Philippines, from Balambangan and the Banggi Islands north of Borneo that are a part of Malaysia's Sabah state.
Borneo is the third largest island in the world. In prehistoric times it was connected to the Asian mainland due to geological and climate changes. During the recent ice ages of the Pleistocene and the Holocene separation from the mainland caused extinctions and speciation of fauna on the island.
The Philippine deer, also known as the Philippine sambar or Philippine brown deer, is a vulnerable deer species endemic to the Philippines. It was first described from introduced populations in the Mariana Islands, hence the specific name.
The Calamian deer, also known as Calamian hog deer, is an endangered species of deer found only in the Calamian Islands of Palawan province in the Philippines. It is one of three species of deer native to the Philippines, the other being the Philippine sambar and the Visayan spotted deer.
The Palawan bearded pig is a pig species in the genus Sus endemic to the Philippines, where it occurs on the archipelago of islands formed by Balabac, Palawan, and the Calamian Islands. It is 1 to 1.6 m in length, about 1 m (3.3 ft) tall and weigh up to 150 kg (330 lb).
The Philippine long-tailed macaque is a subspecies of the crab-eating macaque, known in various Philippine languages as matching/matsing or the more general term unggoy ("monkey"). It is endemic to the Philippine forests and woodlands, but especially in the mangrove forests of western central Philippines— particularly in Palawan, the Visayas, and Mindanao. The names M. f. philippinensis and M. f. philippinenesis have also been used, but arise from orthographical error.
The island of Borneo is located on the Sunda Shelf, which is an extensive region in Southeast Asia of immense importance in terms of biodiversity, biogeography and phylogeography of fauna and flora that had attracted Alfred Russel Wallace and other biologists from all over the world.
Panthera tigris acutidens or Wanhsien tiger is an extinct tiger subspecies, which was scientifically described in 1928 based on fossils excavated near Wanhsien in southern China's Sichuan Province. Otto Zdansky named it Felis acutidens. After the fossils were re-examined in 1947, they were attributed to Panthera tigris acutidens by Dirk Albert Hooijer and Walter W. Granger.
Panthera tigris soloensis, known as the Ngandong tiger, is an extinct subspecies of the modern tiger species. It inhabited the Sundaland region of Indonesia during the Pleistocene epoch.
Dewil Valley, located in the northernmost part of Palawan, an island province of the Philippines that is located in the Mimaropa region, is an archaeological site composed of thousands of artifacts and features. According to the University of the Philippines Archaeological Studies Program, or UP-ASP, the closest settlement can be found in New Ibajay, which is covered by the town capital of El Nido, which is located around 9 km (5.6 mi) south-east of Dewil Valley. Physically it measures around 7 km (4.3 mi) long, and 4 km (2.5 mi) wide. It is in this place which the Ille Cave, one of the main archaeological sites, can be found. It is actually a network of 3 cave mouths located at its base. It has been discovered that this site in particular has been used and occupied by humans over multiple time periods.
