Petenes Mangroves
The Petenes mangroves ecoregion (WWF ID: NT1428) covers mangrove habitat along the Gulf of Mexico coast of southern Mexico, where Campeche state and Yucatan state meet, centering on the Celestun Lagoon inland from the barrier-island town of Celestún. Because the region has relatively little rainfall and no rivers feeding the lagoons, the freshwater to support the mangrove ecosystem springs from underground aquifers. The area is important for migratory birds (there are five areas in this one small ecoregion that have been designated as important bird areas), and as a nesting area for sea turtles. The area around the Celestun Lagoon is protected by the Ría Celestún Biosphere Reserve, a UNESCO Biosphere Reserve. Location and description The ecoregion stretches along 150 km of coastal, from the town of Campeche City to Sisal, Yucatán. The ecoregion only reaches about 10 km inland, to where the salt water influence ends. The region is surrounded inland by the Yucatan ...

Celestún
Celestún is a town in Yucatán, Mexico. It is located in the northwest corner of the state, just north of the border with the state of Campeche, on the Gulf of Mexico coast at . In 2000, it had a population of just under 6,000 people; however, the population swells to 10,000 during the octopus hunting season. It is mostly a fishing town, with a 19th-century lighthouse (as well as a more modern one) and an abandoned historic hacienda. Besides fishing, Celestún also produces salt, as it has done from pre-Columbian times. Tourism is also making up an increasing portion of the town's economy, as the community has many kilometers of sand beaches and abundant wildlife. Surrounding the town is the 147,500-acre (600 km²) Ría Celestún Biosphere Reserve, a wetland reserve that is the winter home to vast flocks of flamingos, as well as many herons and other bird species. This location is set within the Petenes mangroves ecoregion. In addition, more than 200 species of birds p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicornia Bigelovii
''Salicornia bigelovii'' is a species of flowering plant in the family Amaranthaceae known by the common names dwarf saltwort and dwarf glasswort. It is native to coastal areas of the eastern and southern United States, Belize, and coastal Mexico (both the east and west coasts). It is a plant of salt marshes, a halophyte which grows in saltwater. It is an annual herb producing an erect, branching stem which is jointed at many internodes. The fleshy, green to red stem can reach about 60 cm in height. The leaves are usually small plates, pairs of which are fused into a band around the stem. The inflorescence is a dense, sticklike spike of flowers. Each flower is made up of a fused pocket of sepals enclosing the stamens and stigmas, with no petals. The fruit is an utricle containing tiny, fuzzy seeds. The southern part of the species range is represented by the Petenes mangroves of the Yucatán, where it is a subdominant plant associate in the mangroves. Uses This plant is gai ...

Phoenicopterus Ruber
The American flamingo (''Phoenicopterus ruber'') is a large species of flamingo closely related to the greater flamingo and Chilean flamingo native to the Neotropics. It was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is also present in the Galápagos Islands. It is the only flamingo that naturally inhabits North America. Distribution The American flamingo breeds in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago, Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and Cameron Parish, Lou ...

Typha Domingensis
''Typha domingensis'', known commonly as southern cattail or cumbungi, is a perennial herbaceous plant of the genus ''Typha''. Distribution and habitat It is found throughout temperate and tropical regions worldwide. It is sometimes found as a subdominant associate in mangrove ecosystems such as the Petenes mangroves ecoregion of Yucatán. Uses In the Mesopotamian Marshes of southern Iraq, Khirret is a dessert made from the pollen of this plant. In Turkish folk medicine the female inflorescences of this plant and other ''Typha'' are used externally to treat wounds such as burns. Extracts of ''T. domingensis'' have been demonstrated to have wound healing properties in rat models. Water extracts of the fruit, female flower and male flower of ''Typha domingensis'' exhibit iron chelating activity as well as superoxide and nitric oxide Nitric oxide (nitrogen oxide or nitrogen monoxide) is a colorless gas with the formula . It is one of the principal oxides of nitroge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ría Celestún Biosphere Reserve
A ria (; gl, ría) is a coastal inlet formed by the partial submergence of an unglaciated river valley. It is a drowned river valley that remains open to the sea. Definitions Typically rias have a dendritic, treelike outline although they can be straight and without significant branches. This pattern is inherited from the dendritic drainage pattern of the flooded river valley. The drowning of river valleys along a stretch of coast and formation of rias results in an extremely irregular and indented coastline. Often, there are naturally occurring islands, which are summits of partly submerged, pre-existing hill peaks. (Islands may also be artificial, such as those constructed for the Chesapeake Bay Bridge-Tunnel.) A ria coast is a coastline having several parallel rias separated by prominent ridges, extending a distance inland.Goudie, A. (2004) ''Encyclopedia of Geomorphology.'' Routledge.

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'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of The Yucatán Peninsula
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batis Maritima
''Batis maritima'', the saltwort or beachwort (also known as ''turtleweed'', ''pickleweed'', ''barilla'', ''planta de sal'', ''camphire'', ''herbe-à-crâbes'', and ''akulikuli-kai''), is a halophyte. It is a C3-plant, long-lived perennial, dioecious, succulent shrub. The plant forms dense colonies in salt marshes, brackish marshes, and mangrove swamps and frequently is found on the margins of saltpans and wind-tidal flats. Batis maritima is a pioneer plant, covers quickly areas where hurricanes have destroyed the natural vegetation. So far, ''Batis maritima'' has not been used commercially for food production but the seeds have a high oil content with high nutritional value.Massimo F. Marcone, 2003.
