Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possibl ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispaniolan Moist Forests
The Hispaniolan moist forests are a tropical moist broadleaf forest ecoregion on the island of Hispaniola. They cover , around 60% of the island's area. Geography Moist forests occur on most of the eastern half the Dominican Republic, stretching from the coast all the way to high elevations in the mountains. In Haiti, they are found in the Tiburon Peninsula in the southern part of the country as well as the Massif du Nord. The drainage basins for the island's main rivers, the Yaque del Norte and Yaque del Sur, Yuna, and Artibonite, occur in this ecoregion. The forests cover diverse topography, including flatlands, valleys, plateaus, slopes and foothills up to an altitude of about . Soils are either calcareous (neutral or somewhat alkaline) or acidic. Climate Mesic forests receive of annual rainfall, while more than falls in wet forests. The rainy season lasts from April to December. Temperature varies from in open areas near the coast and averages around in higher areas. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical And Subtropical Dry Broadleaf Forests
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispaniolan Dry Forests
The Hispaniolan dry forests are a tropical dry broadleaf forest ecoregion on the island of Hispaniola (split between the Dominican Republic and Haiti). They cover , around 20% of the island's area. Geography The dry forests are found mostly on the southern and western portions of the island of Hispaniola, covering portions of both the Dominican Republic and Haiti. The ecoregion covers the southern and western coastal lowlands, the Cul-de-Sac–Enriquillo lowland, and the Cibao Valley in the north-central portion of the island. Flora Plant communities include high dry forest and cactus scrub dominated by species of ''Prosopis, Pilosocereus, Hippomane, Cylindropuntia, Agave'', and ''Bursera'', as well as '' Melocactus lemairei''.Cano-Ortiz, Ana & Musarella, Carmelo & Piñar Fuentes, José Carlos & Gomes, Carlos & Cano, Eusébio.

Tropical And Subtropical Coniferous Forests
Tropical and subtropical coniferous forests are a tropical forest habitat type defined by the World Wide Fund for Nature. These forests are found predominantly in North and Central America and experience low levels of precipitation and moderate variability in temperature. Tropical and subtropical coniferous forests are characterized by diverse species of conifers, whose needles are adapted to deal with the variable climatic conditions. Most tropical and subtropical coniferous forest ecoregions are found in the Nearctic and Neotropical realms, from the Mid-Atlantic states to Nicaragua and on the Greater Antilles, Bahamas, and Bermuda. Other tropical and subtropical coniferous forests ecoregions occur in Asia. Mexico harbors the world's richest and most complex subtropical coniferous forests. The conifer forests of the Greater Antilles contain many endemics and relictual taxa. Many migratory birds and butterflies spend winter in tropical and subtropical conifer forests. This bio ...

Hispaniolan Pine Forests
The Hispaniolan pine forests are a subtropical coniferous forest ecoregion found on the Caribbean island of Hispaniola, which is shared by Haiti and the Dominican Republic. The ecoregion covers , or about 15% of the island. It lies at elevations greater than in the mountains of Hispaniola, extending from the Cordillera Central of the Dominican Republic and into the Massif du Nord of Haiti. It is surrounded at lower elevations by the Hispaniolan moist forests and Hispaniolan dry forests ecoregions, which cover the remainder of the island. Annual rainfall is . Flora The natural vegetation of the region consists primarily of stands of pino criollo ('' Pinus occidentalis''). Pines are mixed with other conifers, including sabina (''Juniperus gracilior'') and ''Podocarpus aristulatus'' (syn. ''P. buchii''). Below , pine forests are found on lateritic soils and are interspersed with areas of wet montane forest. Important broad-leaved species are '' Garrya fadyenii'' and '' Vaccini ...

Flooded Grasslands And Savannas
Flooded grasslands and savannas is a terrestrial biome of the WWF biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions. Large congregations of migratory and resident waterbirds may be found in these regions. However, the relative importance of these habitat types for these birds as well as more vagile taxa typically varies as the availability of water and productivity annually and seasonally shifts among complexes of smaller and larger wetlands throughout a region. This habitat type is found on four of the continents on Earth. Some globally outstanding flooded savannas and grasslands occur in the Everglades, Pantanal, Lake Chad flooded savanna, Zambezian flooded grasslands, and the Sudd. The Everglades, with an area of , are the world's largest rain-fed flooded grassland on a limestone substrate, and feature some 11,000 species o ...

Mangrove
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of w ...
