Tabasco
Tabasco (), officially the Free and Sovereign State of Tabasco ( es, Estado Libre y Soberano de Tabasco), is one of the 32 Federal Entities of Mexico. It is divided into 17 municipalities and its capital city is Villahermosa. It is located in the southeast of the country, bordering the states of Campeche to the northeast, Veracruz to the west, and Chiapas to the south and the Petén department of Guatemala to the southeast. It has a coastline to the north with the Gulf of Mexico. Most of the state is covered in rainforest as, unlike most other areas of Mexico, it has plentiful rainfall year-round. The state is also home to La Venta, the major site of the Olmec civilization, considered to be the origin of later Mesoamerican cultures. It produces significant quantities of petroleum and natural gas.

Least Concern Biota Of North America
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in Semi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Yucatán Peninsula
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Cyanocorax
''Cyanocorax'' is a genus of New World jays, passerine birds in the family Corvidae. The generic name is derived from the Greek words κυανος (''kuanos''), meaning "dark blue," and κοραξ (''korax''), meaning "raven". It contains several closely related species that primarily are found in wooded habitats of Mexico and Central and South America, with the green jay just barely entering the United States. The genus ''Cyanocorax'' was introduced by the German zoologist Friedrich Boie in 1826, with the plush-crested jay as the type species. Species The genus contains 17 species: Some ornithologists treat the green jay and the Inca jay as conspecific Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organis ..., with ''C. yncas luxuosus'' as the green jay and ''C. yncas yncas'' as t ...

Palenque
Palenque (; Yucatec Maya: ), also anciently known in the Itza Language as Lakamhaʼ ("Big Water or Big Waters"), was a Maya city state in southern Mexico that perished in the 8th century. The Palenque ruins date from ca. 226 BC to ca. 799 AD. After its decline, it was overgrown by the jungle of cedar, mahogany, and sapodilla trees, but has since been excavated and restored. It is located near the Usumacinta River in the Mexican state of Chiapas, about 130 km (81 mi) south of Ciudad del Carmen, above sea level. It averages a humid 26°C (79°F) with roughly of rain a year. Palenque is a medium-sized site, smaller than Tikal, Chichen Itza, or Copán, but it contains some of the finest architecture, sculpture, roof comb and bas-relief carvings that the Mayas produced. Much of the history of Palenque has been reconstructed from reading the hieroglyphic inscriptions on the many monuments; historians now have a long sequence of the ruling dynasty of Palenque in the 5th century ...

Flight Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
