Morne Trois Pitons National Park
Morne Trois Pitons National Park is a national park in Dominica established in July 1975, the first to be legally established in the country. It became a World Heritage Site in 1997. The park is named after its highest mountain, Morne Trois Pitons, meaning mountain of three peaks. The park is an area of significant volcanic activity. Features within the park include the Valley of Desolation, a region of boiling mud ponds and small geysers; the Boiling Lake; Titou Gorge; and Emerald Pool. The mountain is the second-highest peak in Dominica, being exceeded only by Morne Diablotins (). Background The park was established in 1975 and was designated a UNESCO World Heritage Site in 1997. Its area is about , and it is dominated by the Morne Trois Pitons volcanoes (), from which it gets its name. The three major types of geological formations found in the park are volcanic cones, glacis slopes, and soufrières (sulphur deposits). The landscape consists of steep-sided volcanic hills sepa ...

Dominica
Dominica ( or ; Kalinago: ; french: Dominique; Dominican Creole French: ), officially the Commonwealth of Dominica, is an island country in the Caribbean. The capital, Roseau, is located on the western side of the island. It is geographically situated as part of the Windward Islands chain in the Lesser Antilles archipelago in the Caribbean Sea. Dominica's closest neighbours are two constituent territories of the European Union, the overseas departments of France, Guadeloupe to the northwest and Martinique to the south-southeast. Dominica comprises a land area of , and the highest point is Morne Diablotins, at in elevation. The population was 71,293 at the 2011 census. The island was settled by the Arawak arriving from South America in the fifth century. The Kalinago displaced the Arawak by the 15th century. Columbus is said to have passed the island on Sunday, 3 November 1493. It was later colonised by Europeans, predominantly by the French from the 1690s to 1763. The Frenc ...

Geothermal Energy
Geothermal energy is the thermal energy in the Earth's crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. The high temperature and pressure in Earth's interior cause some rock to melt and solid mantle to behave plastically. This results in parts of the mantle convecting upward since it is lighter than the surrounding rock. Temperatures at the core–mantle boundary can reach over 4000 °C (7200 °F). Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since ancient Roman times. More recently geothermal power, the term used for generation of electricity from geothermal energy, has gained in importance. It is estimated that the earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, although only a very small fraction is currently being ...

Dwarf Forest
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal temperate and montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines. High-elevation tropical dwarf forest High-elevation tropical locations in cloud forests contain mossy wet elfin forests due to high-elevation precipitation. These regions are characterized by low rainfall, with most of the wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Rainforest
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, montane grasslands, 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 al ...

Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called abscissio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Tropical Rainforest
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as ''lowland equatorial evergreen rainforest''. True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a sub-set of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical moist broadleaf forest (or tropical wet forest) that also includes the more extensive seasonal tropical forests. Overview Tropical rainforests are characterized by two words: hot and wet. Mean monthly temperatures exceed during all months of the year. Average annual rainfall is no less than and can exceed although it typically lies betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Lift
An aerial lift, also known as a cable car or ropeway, is a means of cable transport in which ''cabins'', ''cars'', ''gondolas'', or open chairs are hauled above the ground by means of one or more cables. Aerial lift systems are frequently employed in a mountainous territory where roads are relatively difficult to build and use, and have seen extensive use in mining. Aerial lift systems are relatively easy to move and have been used to cross rivers and ravines. In more recent times, the cost-effectiveness and flexibility of aerial lifts have seen an increase of gondola lift being integrated into urban public transport systems. Types Cable Car A cable car (British English) or an aerial tramway, aerial tram (American English), uses one or two stationary ropes for support while a separate moving rope provides propulsion. The grip of an aerial tramway is permanently fixed onto the propulsion rope. Aerial trams used for urban transport include the Roosevelt Island Tramway ( New Yor ...
