Sumatran Peat Swamp Forests
The Sumatran peat swamp forests ecoregion (WWF ID: IM0160) covers the low-lying peat swamp forests along the northeast coast of the island of Sumatra in Indonesia. As is typical for peat swamp forests, this ecoregion lies between a thin strip of saltwater-affected mangroves on the coast, and freshwater swamps and lowland rainforest forest on better drained soils further inland. Because the peat soil has relatively low nutrient levels, this ecoregion has been less used for agriculture, but burning and clearance has degraded half of the forest. Location and description The ecoregion stretches for about 1,000 km down the south-eastern side of Sumatra, averaging 75 km wide, and separated from the sea by only a few kilometers of mangroves. It also covers the islands of Rupat, Bengkalis, Tebing Tinggi, Rangsang, and Mendol off the northeast coast of Sumatra. The peat swamps are ombrogenous (rain fed), and form where sediments have piled up behind the tangled brush of the mangroves ...

Indomalayan
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Fabaceae. Major ecolog ...

Tropical Rainforest Climate
A tropical rainforest climate, humid tropical climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, USA, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the Köppen climate classification. A tropical rainforest climate is typically hot, very humid, and wet. Description Tropical rain forests have a type of tropical climate in which there is no dry season—all months have an average precipitation value of at least . There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night ...

Berbak National Park
The Berbak National Park in Sumatra island, Jambi province of Indonesia, forms part of the largest undisturbed swamp forest in southeastern Asia,Indonesian Ministry of Forestry"Berbak National Park", retrieved 04-12-2009 and the peat swamp forest with the greatest number of palm species. Protected since 1935 under Dutch colonial law and later declared a national park, it has been also recognised as a wetland of international importance. Geography Berbak National Park occupies part of the vast alluvial plain of East Sumatra, which comprises approximately one quarter of the island. The region is predominantly flat, being dissected by a number of meandering rivers that drain in a northeasterly direction toward the coast. Along the coast and lower sections of the rivers, extensive beach ridges and intertidal mudflats occur. The area contains 600 km2 of freshwater swamp forest and 1,100 km2 of undisturbed peatswamp forest. Its eastern boundary is bordered by muddy coast an ...

Ploiarium
''Ploiarium'' is a genus of three species of woody plants in the family Bonnetiaceae. It is native to tropical forests and peat swamp forests in Southeast Asia including southern Indochina, Malay Peninsula, Sumatra, and Borneo. Species are generally slow growing with irregular flowering and fruiting cycles. Colonization of plants by arbuscular mycorrhizal fungi is known to improve growth and biomass. Chemistry Species of ''Ploiarium'' are used in medicine as they contain compounds that possess antimicrobial activity. Several xanthones have been discovered in the stems and bark of '' P. elegans'' including: ploiarixanthone, euxanmodin A, and euxanmodin B. The anthraquinones emodin, ploiariquinone A, and 1,8-dihydroxy-3-methoxy-6- methyl-anthraquinone have also been reported from the genus. Triterpenoid benzoates are also reported from the bark of '' P. elegans''. Leaf extracts contain a diverse array of terpenoids, alkaloids, polyphenols, flavonoids, steroids, and saponins ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropical And Subtropical Moist Broadleaf Forests
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
