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.

Julien Joseph Vesque
Julien Joseph Vesque (8 April 1848, in Luxembourg – 25 July 1895, in Paris), was a French naturalist, noted for his work on the agricultural and horticultural benefits deriving from the study of plant physiology. He was the father of Marthe and Juliette, the celebrated circus aficionados known as the Vesque Sisters. Vesque received his early education at the ''Athénée grand-ducal'', moved to Paris in 1871, living and working there for the rest of his life. He held the position of professor from 1880 at the ''Muséum national d'Histoire naturelle'' and from 1883 he was professor at the '' Paris Agricultural Institute'', teaching at the Sorbonne during the same period. His main area of study was water transportation in plants. In 1880 he stated that the movement of water in plants is due to both transpiration and root pressure. He was also interested in the effect of temperature on root absorption of water from the soil. Vesque proved that water moved through the cavities ...

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.

Sepilok
Sepilok Orangutan Rehabilitation Centre is located about 25 kilometres west of Sandakan in the state of Sabah, Malaysia. The centre opened in 1964 as the first official orangutan rehabilitation project for rescued orphaned baby orangutans from logging sites, plantations, illegal hunting or kept as pets. The orphaned orangutans are trained to survive again in the wild and are released as soon as they are ready. The sanctuary is located within the Kabili-Sepilok Forest Reserve which covers an area of , much of which is virgin rainforest. The reserve has been designated an Important Bird Area by BirdLife International BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats. BirdLife International's priorities include preventing extinction of bird species, identifying and safeguarding i .... Today around 60 to 80 orangutans are living free in the reserve.

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] |
