Robinson's Squirrel
''Sundasciurus robinsoni'', or Robinson's squirrel, is a species of rodent in the family Sciuridae. It is found in Indonesia, Malaysia and Thailand. The species ''Sundasciurus robinsoni'' has a Dorsum (anatomy), dorsum that ranges from medium brown with orange Agouti (coloration), agouti to dark brown (''S. r. vanakeni''), and its venter ranges from white to pale yellow/buff white, with a reduction in the extent of this pale coloration and a lack of distinct margins in the case of ''S. r. vanakeni''. Some populations (''S. r. balae'' and ''S. r. vanakeni'') have a grayish ventral coloration in limbs while others do not (''S. r. robinsoni''). It can be easily distinguished from other medium-sized western Sundaland ''Sundasciurus'' based on its ventral coloration and tail. All populations of ''Sundasciurus fraterculus, S. fraterculus'' except Siberut, ''Sundasciurus tahan, S. tahan'', and ''Sundasciurus altitudinis, S. altitudinis'' have a venter fur coloration homogeneously admixed ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Siberut
Siberut is the largest and northernmost of the Mentawai Islands, located 150 kilometres west of Sumatra in the Indian Ocean. It covers an area of 3,838.25 km2 including smaller offshore islands, and had a population of 35,091 at the 2010 Census and 40,220 at the 2020 Census; the official estimate as at mid 2023 was 41,899.Badan Pusat Statistik, Jakarta, 28 February 2024, ''Kabupaten Kepulauan Mentawai Dalam Angka 2024'' (Katalog-BPS 1102001.1301) A part of Indonesia, the island is the most important home for the Mentawai people. The western half of the island was set aside as the Siberut National Park in 1993. Much of the island is covered with rainforest, but is subject to commercial logging. Smaller islands adjacent to Siberut include Karamajet and Masokut which lie in the Bungalaut Strait to the south of the island. The island is known for its range of primates, including the Kloss gibbon (''Hylobates klossii''), pig-tailed langur (''Simias concolor''), Siberut lang ...

Syntopy
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and d ...

Sciuridae
Squirrels are members of the family Sciuridae (), a family that includes small or medium-sized rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin language">Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. ''Sciurus'' is also the name of one of its genuses. The native Old English language, Old English word for the squirrel, , only survived into Middle Eng ...
