Priotelus Roseigaster
The Hispaniolan trogon (''Priotelus roseigaster'') is a species of bird in the family Trogonidae. It is endemic to Hispaniola (both Haiti and the Dominican Republic) in the Caribbean. It is one of the only two trogon species found in the Caribbean. It is the national bird of Haiti. Identification Trogons are brightly coloured birds with long, strongly graduated tails, small feet, and short, thick bills. The Hispaniolan trogon has metallic green upperparts, a gray throat and breast, and a red belly and is separated from the closely related Cuban trogon by the more typical tail of this species. The underside of the tail is dark, but each rectrix is broadly tipped with white. Males and females look similar but the females' wing coverts and secondaries lack the narrow white bars. The male average measurements for wing, tail, culem from base and tarsus are 135.2, 154, 17.3, 16.8 mm respectively. The female averages are 136.6, 154, 16.5, 16.4 mmGerbracht, Jeff. 2011.

Sierra De Bahoruco National Park
The Sierra de Bahoruco National Park is an environmentally protected national park located in the South-western region of Dominican Republic. It was created in 1983 by Presidential Decree (No. 1315/83) during the presidency of Salvador Jorge Blanco. Geography The park is bordered by Lake Enriquillo and Jaragua National Park. Together with the two parks, it constitutes the Jaragua-Bahoruco-Enriquillo biosphere reserve, created on November 6, 2002. The park is located within the provinces of Pedernales Province, Independencia Province and Barahona Province and borders Haiti. It has an area of approximately 1126 km². Part of the park includes the Bahoruco Mountain Range. Also located South-west of the Bahoruco Peninsula is La Bahia de las Aguilas (Bay of Eagle's), a bay which stretches out 8.5 km in length, 5.4 km of which constitutes beach area in its central region, and is a highly protected part of the Biosphere-reserve for its concentration of endemic and endan ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Cordillera Central, Dominican Republic
The Cordillera Central is the highest mountain range in the Dominican Republic and in all of the Caribbean, running through the heart of the island of Hispaniola. Geography The Cordillera Central is home to the highest peaks in the Caribbean: Pico Duarte (3,098 m or 10,164 ft) (the highest point in the Caribbean), La Pelona (3,094 m or 10,150 ft) and La Rucilla (3,049 m or 10,003 ft). Connected to the smaller Massif du Nord in Haiti, it gradually bends southwards and finishes near the town of San Cristóbal on the Caribbean coastal plains. Because of its altitude, cool temperature, and scenic vistas, the Cordillera Central is also known as the " Dominican Alps". Parks José Armando Bermúdez National Park (Parque Nacional Armando Bermúdez) is located in the range, protecting a diversity of flora and fauna species. The pale magnolia tree (''Magnolia pallescens''), an endangered species endemic to the Dominican Republic, grows in the park. Other ranges In the so ...

Forest Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habitat ...

Forest Degradation
Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition. "The forest is still there, but with fewer trees, or less species of trees, plants or animals, or some of them affected by plagues. This degradation makes the forest less valuable and may lead to deforestation. Forest degradation is a type of the more general issue of land degradation. Deforestation and forest degradation continue to take place at alarming rates, which contributes significantly to the ongoing loss of biodiversity. Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breeding Season
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species. Related sexual interest and behaviors are expressed and accepted only during this period. Female seasonal breeders will have one or more estrus cycles only when she is "in season" or fertile and receptive to mating. At other times of the year, they will be anestrus, or have a dearth of their sexual cycle. Unlike reproductive cyclicity, seasonality is described in both males and females. Male seasonal breeders may exhibit changes in testosterone levels, testes weight, and fertility depending on the time of year. Seasonal breeders are distinct from opportunistic breeders, that mate whenever the conditions of their environment become favorable, and continuous breeders that mate year-round. T ...

Anole
Dactyloidae are a family of lizards commonly known as anoles () and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloidae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with ''Polychrus'' (bush anoles), but the latter genus is not closely related to the true anoles. Anoles are small to fairly large lizards, typically green or brownish, but their color varies depending on species and many can also change it. In most species at least the male has a dewlap, an often brightly colored flap of skin that extends from the throat/neck and is used in displays. Anoles share several characteristics with geckos, including details of the foot structure (for climbing) and the ability to voluntarily break off the tail (to escape predators), but they are only very distantly related, anoles being part of Iguania. ...

Sierra De Baoruco
The Bahoruco Mountain Range—Sierra de Bahoruco (or Sierra de Bahoruco) is a mountain range located in the far southwestern region of the Dominican Republic. It is within Pedernales Province, Pedernales, Independencia Province, Independencia, Barahona Province, Barahona, and Bahoruco Provinces. A large part of the area is protected within the Sierra de Bahoruco National Park (''Parque Nacional Sierra de Bahoruco''), also a Biosphere reserve. Its name is mentioned for the first time by Bartolomé de las Casas in his "Brief History of the Indies", who takes it from the phonetic sound used by the Taino Indians to describe that region. It is rich in deposits of salt and gypsum, and also has a lagoon in the southern part (Oviedo lagoon) and between this mountain range and the Neiba mountain range is Lake Enriquillo, the largest in the Antilles.
