Usumacinta Mangroves
The Usumacinta mangroves ecoregion (WWF ID: NT1437) covers the mangrove forests ont the Gulf Coast of Mexico, around the margins of the Laguna de TĂ©rminos ("Lagoon of Ends"). The "Ends" in the name refer to the mouths of the rivers that empty into the lagoon, including the Usumacinta River. This region, which is due south of the mouth of the Mississippi River across the Gulf of Mexico, receives an estimated one-third of the wintering birds migrating on the Mississippi Flyway. It is estimated that the lagoon supports 90 endangered species. Location and description The lagoon and surroundings are in Campeche State of Mexico. The mangroves cover the river deltas of the Usumacinta River and Grijalva River. They also cover the margins of the lagoon and inland for 5 km or so where the balance of saline and fresh water supports mangrove species. The lagoon is a RAMSAR wetland of international importance. The surrounding inland ecoregion is the Pantanos de Centla ecoregion. Climate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pantanos De Centla
The Pantanos de Centla (Centla swamps) are wooded wetlands along the coast in state of Tabasco in Mexico. They have been protected since 2006 with the establishment of the Pantanos de Centla Biosphere Reserve. It is also a World Wildlife Fund ecoregion. WWF Ecoregion The ecoregion covers an area of in the states of Tabasco and Campeche. The Centla swamps occupy the delta of the Usumacinta and Grijalva rivers, which empty into the Gulf of Mexico and the Laguna de Términos through numerous distributaries. The ecoregion includes year-round wetlands, and freshwater swamp forests which are inundated during the summer rainy season. The Usumacinta mangroves lie in the brackish-water zone between the Centla swamps and the open water of the Laguna de Términos and the Gulf. The Petén–Veracruz moist forests lie to the west and south, and the Yucatan moist forests lie to the east. A 2017 assessment found that 5,644 km2, or 33%, of the ecoregion is in protected areas.

Ecoregions Of Mexico
The following is a list of ecoregions in Mexico as identified by the World Wide Fund for Nature (WWF). A different system of ecoregional analysis is used by the Commission for Environmental Cooperation, a trilateral body linking Mexican, Canadian and United States environmental regime. Terrestrial ecoregions The terrestrial ecoregions of Mexico span two biogeographic realms - the Nearctic and Neotropic - which together constitute the entire biogeography of the Americas. Veracruz is the most biodiverse state with 10 ecoregions across 5 biomes and 2 realms. Chiapas comes in a close second with 10 ecoregions across 4 biomes in the same realm. By contrast, Morelos and Mexico City are the least biodiverse states with just 2 ecoregions each.

Neotropical Ecoregions
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dalbergia
''Dalbergia'' is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic ''Dalbergia'' clade (or tribe): the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia. Fossil record A fossil †''Dalbergia phleboptera'' seed pod has been found in a Chattian deposit, in the municipality of Aix-en-Provence in France. Fossils of †''Dalbergia nostratum'' have been found in rhyodacite tuff of Lower Miocene age in Southern Slovakia near the town of Lučenec. Fossil seed pods of †''Dalbergia mecsekense'' have been found in a Sarmatian deposit in Hungary. †''Dalbergia lucida'' fossils have been described from the Xiaolongtan Formation of late Miocene age in Kaiyuan County, Yunnan Province, China.

Avicennia Germinans
''Avicennia germinans'', the black mangrove, is a shrub or small tree growing up to 12 meters (39 feet) in the acanthus family, Acanthaceae. It grows in tropical and subtropical regions of the Americas, on both the Atlantic and Pacific Coasts, and on the Atlantic Coast of tropical Africa, where it thrives on the sandy and muddy shores where seawater reaches. It is common throughout coastal areas of Texas and Florida, and ranges as far north as southern Louisiana and coastal Georgia in the United States. Like many other mangrove species, it reproduces by vivipary. Seeds are encased in a fruit, which reveals the germinated seedling when it falls into the water. Unlike other mangrove species, it does not grow on prop roots, but possesses pneumatophores that allow its roots to breathe even when submerged. It is a hardy species and expels absorbed salt mainly from its leathery leaves. The name "black mangrove" refers to the color of the trunk and heartwood. The leaves often appear ...

Laguncularia Racemosa
''Laguncularia racemosa'', the white mangrove, is a species of flowering plant in the leadwood tree family, Combretaceae. It is native to the coasts of western Africa from Senegal to Cameroon, the Atlantic Coast of the Americas from Bermuda and Florida to the Bahamas, Mexico, the Caribbean, and south to Brazil; and on the Pacific Coast of the Americas from Mexico to northwestern Peru, including the Galápagos Islands. It is a mangrove tree, growing to tall. The bark is gray-brown or reddish, and rough and fissured. Pneumatophores and/or prop roots may be present, depending on environmental conditions. The leaves are opposite, elliptical, long, and broad, rounded at both ends, entire, smooth, leathery in texture, slightly fleshy, without visible veins, and yellow-green in color. The petiole is stout, reddish, and long, with two small glands near the blade that exude sugars. The white, bell-shaped flowers are mostly bisexual and about long. The fruit is a reddish-brown dr ...

Rhizophora Mangle
''Rhizophora mangle'', the red mangrove, is distributed in Estuary, estuarine ecosystems throughout the tropics. Its Vivipary, viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows. ''Rhizophora mangle'' grows on Aerial root#Aerial roots as supports, aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree ''(Schinus terebinthifolius)''. The red mangrove itself is considered an invasive species in some locations, such as Hawaii, where it forms dense, monoculture, monospecific thickets. ''R. mangle'' thickets, however, provide nesting and hunting habitat for a diverse array of organisms, including fish, birds, and cro ...

Tropical Savanna Climate With Dry-winter Characteristics
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Savanna Climate
Tropical savanna climate or tropical wet and dry climate is a tropical climate sub-type that corresponds to the Köppen climate classification categories ''Aw'' (for a dry winter) and ''As'' (for a dry summer). The driest month has less than of precipitation and also less than 100-\left (\frac \right)mm of precipitation. This latter fact is in a direct contrast to a tropical monsoon climate, whose driest month sees less than of precipitation but has ''more'' than 100-\left (\frac \right) of precipitation. In essence, a tropical savanna climate tends to either see less overall rainfall than a tropical monsoon climate or have more pronounced dry season(s). In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year. Tropical savanna climates often feature tree-studded grasslands due to its dryness, rather than thick jungle. It is this widespread occurrence of tall, coarse grass (called savanna) which has led to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
