Conifer
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpaceae
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 19 genera if '' Phyllocladus'' is included and '' Manoao'' and '' Sundacarpus'' are recognized. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and '' Nageia'' into southern China and southern India. Two genera also occur in sub-Saharan Africa, the widespread ''Podocarpus'' and the endemic ''Afrocarpus''. '' Parasitaxus usta'' is ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trinidad
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of , it is also the fifth largest in the West Indies. Name The original name for the island in the Arawaks' language was which meant "Land of the Hummingbird". Christopher Columbus renamed it ('The Island of the Trinity'), fulfilling a vow he had made before setting out on his third voyage. This has since been shortened to ''Trinidad''. History Caribs and Arawaks lived in Trinidad long before Christopher Columbus encountered the islands on his third voyage on 31 July 1498. The island remained Spanish until 1797, but it was largely settled by French colonists from the French Caribbean, especially Martinique.Besson, Gerard (2000-08-27).

Central Range, Trinidad And Tobago
The Central Range is a mountain range on the island of Trinidad. It extends diagonally across the island and is a low-lying range rising from swampy areas into rolling hills. The tallest hills in the range are Mount Tamana (307 mDay, M.J. and Chenoweth, M.S. 2004. The karstlands of Trinidad and Tobago, their land use and conservation. ''The Geographical Journal'' 170:256–266), Mount Harris and Brigand Hill; all located in the northeastern portion of the range. The Central Range mountains are biodiverse, and are home to the Tamana Caves - the site of Trinidad's largest bat roost. Howler monkeys can be found here and numerous species of birds as well. There are numerous streams and clean springs that flow from the Central Range. However there are few waterfalls. The most prominent of these falls are the Brasso Venado falls in Brasso Venado, and Gran Couva falls, or Carmelita falls, located in Gran Couva. To the north of the range are the Northern Lowlands ( East–West Corridor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Range
The Northern Range is the range of tall hills across north Trinidad, the major island in the Republic of Trinidad and Tobago. The hills range from the Chaguaramas peninsula on the west coast to Toco in the east. The Northern Range covers approximately twenty-five percent of the land area of Trinidad. Geography The Northern Range runs from the Chaguaramas Peninsula in the west to Toco in the east. The eastern Northern Range (areas east of Arima) remain most heavily forested. Portions west of Arima, especially the southern slopes and valleys, have been extensively deforested, since they lie immediately north of the most heavily populated parts of the island. At the western end of the Northern Range, the capital city, Port of Spain, climbs into the hills and the valleys are settled and largely deforested. The Arima Valley remains as the westernmost valley that is still primarily forested, in a large part due to the presence of the Asa Wright Nature Centre in this valley. T ...

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 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 re-evaluating near-threatened taxon 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. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocarpus
''Podocarpus'' () is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς (poús, “foot”) + καρπός (karpós, “fruit”). ''Podocarpus'' species are evergreen shrubs or trees, usually from tall, known to reach at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.Earle, Chris J.''Podocarpus''.The Gymnosperm Database. 2013. Species are cultivated as ornamental plants for parks and large gardens. The cultivar 'County Park Fire' has won the Royal Horticultural Society's Award of Garden Merit. Names and etymology Common names for various species include "yellowwood" and "pine", as in the plum pine ('' Podoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern Plants
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Trinidad And Tobago
The endemic flora of Trinidad and Tobago includes a total of 59 species of vascular plants belonging to 34 plant families. This is less than 3% of the total vascular plant flora of Trinidad and Tobago. Thirty-nine of these species are endemic to Trinidad, 12 are Tobagonian endemics, and six are present on both islands. Island systems tend to be rich centres of endemism as a result of their isolation. The islands of the Greater Antilles have rates of endemism which range from 12-50% of their flora. Trinidad and Tobago has a far lower rate of endemism, probably as a result of its geological history. The islands of Trinidad and Tobago lie on the South American continental shelf, and were both connected to the mainland during the Pleistocene. Tobago was separated from the mainland about 13,000 years ago; Trinidad was connected until more recently, and may only have become separated about 1,500 years ago. The flora of Trinidad and Tobago has been estimated to include about 2,5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
