Shorea Exelliptica
''Shorea exelliptica'' is a species of plant in the family Dipterocarpaceae. This species has previously been confused with ''Shorea elliptica'' and the species name is derived to highlight this point (' = excluded from). ''S. exelliptica'' is found in Peninsular Malaysia and Borneo. It is an emergent tree, up to tall, found in mixed dipterocarp forest on yellow clay and sandy clay soils on sedimentary rock. It is found in at least two protected areas ( Lambir Hills and Gunung Mulu Mount Mulu () is a sandstone and shale mountain. At 2376 m, it is the second highest mountain in the state of Sarawak, after Mount Murud. It is located within the boundaries of Gunung Mulu National Park, which is named after it. History I ...

Meijer returned to Europe on leave again in 1966. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dipterocarpaceae
Dipterocarpaceae is a family (biology), family of flowering plants with 22 genera and about 695 known species of mainly lowland tropical forest trees. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. The greatest diversity of Dipterocarpaceae occurs in Borneo.Ashton, P.S. Dipterocarpaceae.

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere.

Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Lambir Hills National Park
The Lambir Hills National Park () is a national park in Miri Division, Sarawak, Malaysia, on the island of Borneo. It is a small park, at , and is composed largely of mixed dipterocarp forest, with some small areas of 'kerangas' (heath forest). The park is above sea level. Animal life Biologists have recorded 237 species of birds, 64 species of mammals, 46 species of reptiles and 20 species of frogs in the national park. Large mammals such as gibbons and sun bear are absent or very rare due to the small size of the forest and illegal hunting. More recent surveys (2003–2007), however, failed to find 20% of the park's resident bird species and 22% of the mammal species, losses that include half of the park's primate species and six out of seven hornbill species. Collapse in population of large mammals and birds is an ecological disaster in Lambir. The park's invertebrates include the Rajah Brooke's Birdwing butterfly ('' Trogonoptera brookiana'') and more than 300 species of ...

Gunung Mulu National Park
The Gunung Mulu National Park, also known simply as the Mulu National Park is a national park in Miri Division, Sarawak, Malaysia. It is a UNESCO World Heritage Site that encompasses caves and Karst topography, karst formations in a mountainous tropical rainforest, equatorial rainforest setting. The park is famous for its caves and the expeditions that have been mounted to explore them and their surrounding rainforest, most notably the Royal Geographical Society Expedition of 1977–1978, which saw over 100 scientists in the field for 15 months. This initiated a series of over 20 expeditions now named the Mulu Caves Project. The national park is named after Mount Mulu, the second highest mountain in Sarawak. History The earliest reference to the Mulu caves was in 1858 when Spenser St. John (British Consul in Brunei) mentioned the "detached masses of limestone, much water-worn, with caverns and natural tunnels” in his book ''Life in the Forests of the Far East''.

List Of Shorea Species
''Shorea'' is a large genus in family Dipterocarpaceae, and has been subject to substantial revision over the decades. Prior to 2022 the genus included nearly 200 genera. Based on phylogenomic analyses showing that genus ''Shorea'' sensu Ashton (1982) was polyphyletic, in 2022 Ashton and Heckenhauer proposed reviving the former genera ''Doona'' Thwaites, ''Pentacme'' A.DC., and ''Richetia'' F.Heim, raising ''Shorea'' sections ''Anthoshorea'' and ''Neohopea'' to genus rank, and combining ''Shorea'' sections ''Brachyptera'', ''Mutica'', ''Ovalis'', ''Pachycarpae'', and ''Rubella'' into the new genus ''Rubroshorea'', with two sections, ''Shorea'' and ''Barbata'', remaining in genus ''Shorea''.Ashton, P.S., Heckenhauer, J.

Forest Research Institute Malaysia
The Forest Research Institute Malaysia (FRIM; Malay: ''Institut Penyelidikan Perhutanan Malaysia'') is a statutory agency of the Government of Malaysia, under the Natural Resources and Environmental Sustainability (NRES). FRIM promotes sustainable management and optimal use of forest resources in Malaysia by generating knowledge and technology through research, development and application in tropical forestry. FRIM is located in Kepong, near Kuala Lumpur. FRIM is the world's oldest and largest re-created tropical rain forest. History In 1926, the chief conservator of the forest (equivalent to today's director of forestry), G.E.S Cubitt, asked F.W. Foxworthy to establish a separate forest research unit for the Forestry Department. It was Foxworthy who selected the present site, at Kepong. He was also to become the institute's first chief research officer. The site comprised an area that was practically stripped of its original forest cover except for a few remnant trees ...

Trees Of Peninsular Malaysia
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
