Thymelaeaceae
The Thymelaeaceae are a cosmopolitan family (biology), family of flowering plants composed of 50 genera (listed below) and 898 species.Zachary S. Rogers (2009 onwards)A World Checklist of Thymelaeaceae (version 1) Missouri Botanical Garden Website, St. Louis. It was established in 1789 by Antoine Laurent de Jussieu.Antoine Laurent de Jussieu ''Genera Plantarum'', page 76. Herrisant & Barrois, Paris. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants. Description Several conspicuous or unusual traits are characteristic of the family (when ''Tepuianthus'' is excluded). The bark is usually shiny and fibrous, with strips of bark peeling down the side of broken stems.Ernst Schmidt, Mervyn Lotter and Warren McCleland The number of stamens is usually once or twice the number of calyx (botany), calyx lobes; when twice, they often occur in two well separated series. Exceptions include ''Gonystylus'', which may have up to 100 stamens, and ''Pimelea'', w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submontane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...

Kerangas
The Sundaland heath forests, also known as ''Kerangas'' forest, is a type of tropical moist forest found on the island of Borneo, which is divided between Brunei, Indonesia, and Malaysia, as well as on the Indonesian islands of Belitung and Bangka, which lie to the west of Borneo. Setting The word ''Kerangas'', which means "land which cannot grow rice", comes from the Iban language. Heath forests occur on acidic sandy soils that are the result of the area's siliceous parent rocks. Permanently waterlogged heath forests are known as ''kerapah'' forests.Wikramanayake, Eric; Eric Dinerstein; Colby J. Loucks; et al. (2002).

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of reevaluating near-threatened taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Those designated since 2001 that depend on conservation efforts to not become threatened are no longer separately considered conservation-dependent species. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependent", LR/cd). With this category system, Near Threatened and Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Palm Oil
Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. Palm oils are easier to stabilize and maintain quality of flavor and consistency in ultra-processed foods, so they are frequently favored by food manufacturers. Globally, humans consumed an average of of palm oil per person in 2015. Demand has also increased for other uses, such as cosmetics and biofuels, encouraging the growth of palm oil plantations in tropical countries. The mass production of palm oil in the tropics has attracted the concern of environmental and human rights groups. The palm oil industry is a significant contributor to deforestation in the tropics where palms are grown and has been cited as a factor in social problems due to allegations of human rights violations among growers. In 2018, a repor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Sumatra
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that 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 around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
