Tulum Municipality
Tulum Municipality (, ) is one of the eleven municipalities that make up the Mexican state of Quintana Roo. It became a municipality when it was formed on 13 March 2008, at which time it was separated from Solidaridad Municipality. Tulum is home to the Maya archaeological sites of Tulum and Cobá. Geography The municipality of Tulum borders the municipalities of Solidaridad to the north and Felipe Carrillo Puerto to the south, in the state of Quintana Roo. It also borders Chemax Municipality and Valladolid Municipality in the state of Yucatán on the northwest, and the Caribbean Sea on the east. Orography and hydrography Like most of the Yucatan Peninsula Tulum is entirely flat with a gentle slope towards the sea, so from west to east, the area never reaches an altitude higher than above sea level. The municipality is above sea level on average. Like the rest of the peninsula's surface the land has a limestone base that does not allow the formation of surface water ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, ...

Crocodylus Acutus
''Crocodylus'' is a genus of true crocodiles in the family Crocodylidae. Taxonomy The generic name, ''Crocodylus'', was proposed by Josephus Nicolaus Laurenti in 1768. ''Crocodylus'' contains 13–14 extant (living) species and 5 extinct species. There are additional extinct species attributed to the genus ''Crocodylus'' that studies have shown no longer belong, although they have not yet been reassigned to new genera. Extant species The 13–14 living species are: Fossils ''Crocodylus'' also includes five extinct species: * † '' Crocodylus anthropophagus'' is an extinct crocodile from Plio-Pleistocene of Tanzania. * † '' Crocodylus checchiai'' is an extinct crocodile from Late Miocene of Kenya. * † '' Crocodylus falconensis'' is an extinct crocodile from Early Pliocene of Venezuela. * † '' Crocodylus palaeindicus'' is an extinct crocodile the Miocene to the Pleistocene of southern Asia. * † '' Crocodylus thorbjarnarsoni'' is an extinct crocodile from Plio-Pleistoc ...

Crax Rubra
The great curassow (''Crax rubra'') is a large, pheasant-like bird from the Neotropical rainforests, its range extending from eastern Mexico, through Central America to western Colombia and northwestern Ecuador. Male birds are black with curly crests and yellow beaks; females come in three colour morphs, barred, rufous and black. These birds form small groups, foraging mainly on the ground for fruits and arthropods, and the occasional small vertebrate, but they roost and nest in trees. This species is monogamous, the male usually building the rather small nest of leaves in which two eggs are laid. This species is threatened by loss of habitat and hunting, and the International Union for Conservation of Nature has rated its conservation status as " vulnerable". Taxonomy The great curassow is the most northerly ''Crax'' species. It is part of a clade that inhabited the north of South America since about 9 mya (Tortonian, Late Miocene). As the Colombian Andes were uplifted around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caracara Plancus
The crested caracara (''Caracara plancus'') is a bird of prey (raptor) in the falcon family, Falconidae. It was formerly placed in the genus ''Polyborus'' before being given in its own genus, '' Caracara''. It is native to and found in the southern and southeastern United States, Mexico (where it is present in every state) and the majority of mainland Latin America, as well as some Caribbean islands. The crested caracara is quite adaptable and hardy, for a species found predominantly in the neotropics; it can be found in a range of environments and ecosystems, including semi-arid and desert climates, maritime or coastal areas, subtropical and tropical forests, temperate regions, plains, swamps, and even in urban areas. Documented, albeit rare, sightings have occurred as far north as Minnesota and the Canadian provinces of Ontario and Prince Edward Island. The southern extent of the crested caracara's distribution can reach as far as Tierra del Fuego and Magallanes Region, Chile. ...

Ateles Geoffroyi
Geoffroy's spider monkey (''Ateles geoffroyi''), also known as the black-handed spider monkey or the Central American spider monkey, is a species of spider monkey, a type of New World monkey, from Central America, parts of Mexico and possibly a small portion of Colombia. There are at least five subspecies. Some primatologists classify the black-headed spider monkey (''A. fusciceps''), found in Panama, Colombia, and Ecuador as the same species as Geoffroy's spider monkey. It is one of the largest New World monkeys, often weighing as much as . Its arms are significantly longer than its legs, and its prehensile tail can support the entire weight of the monkey and is used as an extra limb. Its hands have only a vestigial thumb, but long, strong, hook-like fingers. These adaptations allow the monkey to move by swinging by its arms beneath the tree branches. Geoffroy's spider monkey lives in fission–fusion societies that contain between 20 and 42 members. Its diet consists pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ardea Herodias
The great blue heron (''Ardea herodias'') is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North and Central America, as well as far northwestern South America, the Caribbean and the Galápagos Islands. It is occasionally found in the Azores and is a rare vagrant to Europe. An all-white population found in south Florida and the Florida Keys is known as the great white heron. Debate exists about whether these white birds are a color morph of the great blue heron, a subspecies of it, or an entirely separate species. Taxonomy The great blue heron was one of the many species originally described by Carl Linnaeus in his 18th-century work, ''Systema Naturae''. The scientific name comes from Latin , and Ancient Greek (), both meaning "heron". The great blue heron's niche in the Old World is filled by the congeneric grey heron (''Ardea cinerea''), which is somewhat smaller (), and sports a pale gray neck and legs, ...

Riviera Maya
The Riviera Maya () is a tourism and resort district south of Cancun, Mexico. It straddles the coastal Federal Highway 307, along the Caribbean coastline of the state of Quintana Roo, located in the eastern portion of the Yucatán Peninsula. Originally the name applied narrowly, focusing on the area of coastline between the city of Playa del Carmen and Tulum. The designation has since expanded up and down the coast, now including the towns of Puerto Morelos, situated to the north of Playa del Carmen, as well as the town of Felipe Carrillo Puerto, situated to the south of Tulum. This larger region is what is currently being promoted as part of the Riviera Maya tourist corridor. Once the area was originally only called the "Cancun–Tulum corridor", but in 1999 it was renamed as the Riviera Maya, analogous to the Italian and French Riviera, with the instigation of among others, Miguel Ramón Martín Azueta. At the time, he was the municipal president of Solidaridad, Quin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is 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 one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decauville Railway Vigía Chico-Santa Cruz
The Decauville railway Vigía Chico-Santa Cruz (Spanish Ferroaril Decauville de Vigía Chico) was a nearly long gauge railway line, which was built during the Caste War of Yucatán at Santa Cruz (now Felipe Carrillo Puerto) in Mexico and operated from 1905 to 1932. History On 13 December 1901, the material for the railway was ordered in New Orleans. On 16 April 1902, a shipload of 250 tons of narrow-gauge railway material was delivered to the General Vega Camp at the port of Vigía Chico. The track was officially opened on 4 September 1905. Between 1905 and 1912, the Mayas carried out continuous harassment and attacks on the military railway. When General Ignacio A. Bravo (1837–1918) was expelled from Santa Cruz, the Mayas began to destroy the railway. In 1913, the governor of the territory, General Arturo Gracilazo Juárez, ordered its reconstruction. In 1918, General Venustiano Carranza granted the Mayan leader Francisco May a license to use the narrow-gauge railway t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
