Coiba
Coiba () is the largest island in Central America, with an area of , off the Pacific coast of the Panamanian province of Veraguas. It is part of the Montijo District of that province. History Coiba separated from continental Panama between 12,000 and 18,000 years ago when sea levels rose. Plants and animals on the new island became isolated from mainland populations and over the millennia most animals have diverged in appearance and behaviour from their mainland counterparts. The island is home to many endemic subspecies, including the Coiba Island howler monkey, and the Coiba spinetail. In 1919, a penal colony was built on the island and during the years that Panama was under the dictatorships of Omar Torrijos and Manuel Noriega, the prison on Coiba was a feared place with a reputation for brutal conditions, extreme torture, executions and political murders. Nobody knows exactly how many people were killed in the prison during that period, but sources claim that the number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Submarine Canyon
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to , from canyon floor to canyon rim, as with the Great Bahama Canyon. Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor. Turbidity currents are flows of dense, sediment laden waters that are supplied by rivers, or generated on the seabed by storms, submarine landslides, earthquakes, and other soil disturbances. Turbidity currents travel down slope at great speed (as much as ), eroding the continental slope and finally depositing sediment onto the abyssal plain, where the particles settle out.Continental Margin Sedimentation: From Sediment Transport to Sequence Stratigraphy (Special Publication 37 of the IAS) March 2009, by Charles ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an "''insular shelf''." The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores ...

Brown Pelican
The brown pelican (''Pelecanus occidentalis'') is a bird of the pelican family, Pelecanidae, one of three species found in the Americas and one of two that feed by diving into water. It is found on the Atlantic Coast from New Jersey to the mouth of the Amazon River, and along the Pacific Coast from British Columbia to Peru, including the Galapagos Islands. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. The brown pelican mainly feeds o ...

Brown Booby
The brown booby (''Sula leucogaster'') is a large seabird of the booby family Sulidae, of which it is perhaps the most common and widespread species. It has a pantropical range, which overlaps with that of other booby species. The gregarious brown booby commutes and forages at low height over inshore waters. Flocks plunge-dive to take small fish, especially when these are driven near the surface by their predators. They nest only on the ground, and roost on solid objects rather than the water surface. Taxonomy The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his ''Histoire Naturelle des Oiseaux'' in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine ecosystem, marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding ecological niche, niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous geological period, period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, Reproduction, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in Bird colony, colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual bird migration, migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colony (biology)
In biology, a colony is composed of two or more Biological specificity#Conspecific, conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be Modularity, modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bananaquit
The bananaquit (''Coereba flaveola'') is a species of passerine bird in the tanager family Thraupidae. Before the development of molecular genetics in the 21st century, its relationship to other species was uncertain and it was either placed with the buntings and New World sparrows in the family Emberizidae, with New World warblers in the family Parulidae or its own monotypic family Coerebidae. This small, active nectarivore is found in warmer parts of the Americas and is generally common. Its name is derived from its yellow color and the English word '' quit'', which refers to small passerines of tropical America; cf. grassquit, orangequit. Taxonomy The bananaquit was formally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Certhia flaveola''. Linnaeus based his description on the "black and yellow bird" described by John Ray and Hans Sloane, and the "Black and Yellow Creeper" described and illustrated by George Edwards in 1751. The ...

Rufous-tailed Hummingbird
The rufous-tailed hummingbird (''Amazilia tzacatl'') is a medium-sized hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found from east-central Mexico through Central America and Colombia into Ecuador and Venezuela. Taxonomy The rufous-tailed hummingbird was formally described in 1833 by the Mexican naturalist Pablo de La Llave. He placed it in the genus '' Trochlilus'' and coined the binomial name ''Trochilus tzacatl''. The rufous-tailed hummingbird is now placed in the genus ''Amazilia'' and was introduced in 1843 by the French naturalist René Lesson. The genus name comes from the Inca heroine in Jean-François Marmontel's novel ''Les Incas, ou la destruction de l'Empire du Pérou''. The specific epithet is from Aztec mythology: Tzacatl was a warrior chief. The rufous-tailed hummingbird has these five recognized subspecies: *''A. t. tzacatl'' ( La Llave, 1833) *''A. t. handleyi'' Wetmore, 1963 *''A. t. fuscicaudata'' (Fraser, 1840) *''A. ...
