DVCA
Danum Valley Conservation Area is a tract of relatively undisturbed lowland dipterocarp forest in Sabah, Malaysia. It has an extensive diversity of tropical flora and fauna, including species such as the rare Bornean orangutan, gibbons, mousedeer, clouded leopards and over 270 bird species. Visitor activities include jungle treks, river swimming, birdwatching, night jungle tours and excursions to nearby logging sites and timber mills. There were no human settlements within the area before it became a conservation area, meaning that hunting, logging and other human interference were non-existent, making the area almost unique. It is managed by Yayasan Sabah for conservation, research, education, and habitat restoration training purposes. There have been proposals to nominate the site as a UNESCO World Heritage Site. Geography The nearest town, Lahad Datu is about away, about a 2 hours' drive on mainly logging roads. Danum Valley Field Centre is a research establishm ...

Borneo
Borneo () is the List of islands by area, third-largest island in the world, with an area of , and population of 23,053,723 (2020 national censuses). Situated at the geographic centre of Maritime Southeast Asia, it is one of the Greater Sunda Islands, located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The island is crossed by the equator, which divides it roughly in half. The list of divided islands, island is politically divided among three states. The sovereign state of Brunei in the north makes up 1% of the territory. Approximately 73% of Borneo is Indonesian territory, and in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. Etymology When the sixteenth-century Portuguese explorer Jorge de Menezes made contact with the indigenous people of Borneo, they referred to their island as ''Pulu K'lemantang'', which ...

Dipterocarpus Caudatus
''Dipterocarpus condorensis'' is a species of plant in the evergreen or semi-evergreen family Dipterocarpaceae. It is an emergent tree, up to 50 m tall, in mixed dipterocarp forest on dry ridges. It is found in Sumatra, coastal Peninsular Malaysia, Singapore, and Borneo, the Philippines, and Vietnam. It is a medium hardwood sold under the trade names of Keruing. It was formerly most abundant along the coastal hills on sandy soils, but is endangered due to land conversion. ''D. condoriensis'' is found in at least one protected area ( Sepilok Forest Reserve). Subspecies There are two accepted subspecies: * ''Dipterocarpus condorensis'' subsp.

Dipterocarpus Acutangulus
''Dipterocarpus acutangulus'' is a species of tree in the family Dipterocarpaceae. The species name ''acutangulus'' is derived from Latin (''angulus'' = angle, ''acutus'' = sharp) and refers to the ribs of the fruit calyx tube. It is native to peninsular Thailand and Malaysia and also Borneo, where it is locally known as keruing merkah or keruing beludu. It is an emergent tree up to 60 m tall. The tree occurs in mixed dipterocarp forest Dipterocarpaceae is a family of flowering plants with 22 genera and about 695 known species of mainly lowland tropical forest trees.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Dipterocarpus
'' D. retusus'' in Köhler ''Dipterocarpus'' is a genus of flowering plants and the type genus of family Dipterocarpaceae. ''Dipterocarpus'' is the third-largest and most diverse genus among the Dipterocarpaceae. The species are well known for timber, but less acknowledged for use in traditional herbal medicine. The genus has about 70 species, occurring in South Asia and Southeast Asia, from Sri Lanka and India to the Philippines. It is an important component of dipterocarp forests. Its generic name comes from Greek and means "two-winged fruits". The greatest diversity of ''Dipterocarpus'' species occurs on Borneo, with many endemic to the island. The oldest fossil of the genus, and Dipterocarpaceae, is from the latest Cretaceous (Maastrichtian) Intertrappean Beds of India. Uses The genus is of considerable importance as timber trees and for producing resinous oil. The oil is sold under the trade names gurjun oil, kanyin oil, wood oil, and Keruing oil.

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial molluscs, terrestrial gastropod mollusks that have gastropod shell, shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a Polyphyly, polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum (gastropod), operculum. The largest clade of non-pulmonate land snails is the Cyclophoroidea, with more than 7,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bornean Rhinoceros
The Bornean rhinoceros (''Dicerorhinus sumatrensis harrissoni''), also known as the eastern Sumatran rhinoceros or eastern hairy rhinoceros, is one of three subspecies of Sumatran rhinoceros. The subspecies was feared to be functionally extinct, with only one individual, a female named Pahu, surviving in captivity, and held in the state of Sabah. In April 2015, the Malaysian government declared the Bornean rhinoceros to be extinct in the wild in the Malaysian portion of Borneo. However, in March 2016, a young female rhino was captured in East Kalimantan (in the Indonesian portion of Borneo), providing evidence of their continued existence. The International Union for Conservation of Nature (IUCN) classifies the subspecies as critically endangered. Taxonomy The Bornean subspecies ''Dicerorhinus sumatrensis harrissoni'', was named in honour of the British polymath Tom Harrisson, who worked extensively with Bornean zoology and anthropology in the 1960s.

Sun Bear
The sun bear (''Helarctos malayanus'') is a bear species in the Family (biology), family Ursidae found in the tropical forests of Southeast Asia. It is the only species in the genus ''Helarctos'' and the smallest bear species, standing nearly at the shoulder and weighing . It is stockily built, with large paws, strongly curved claws, small, rounded ears and a short snout. The fur is generally short and jet black, but can vary from grey to red. The sun bear gets its name from its characteristic orange to cream-coloured chest patch. Its unique Morphology (biology), morphology—inward-turned front feet, flattened chest, powerful forelimbs with large claws—suggests adaptations for climbing. The most Arboreality, arboreal (tree-living) of all bears, the sun bear is an excellent climber and sunbathes or sleeps in trees above the ground. It is mainly active during the day, though nocturnality might be more common in areas frequented by humans. Sun bears tend to remain solitary, b ...
