Eleutherodactylus Jugans
The La Selle dusky frog or Mable's robber frog (''Eleutherodactylus jugans'') is a species of frog in the family Eleutherodactylidae. It is endemic to Hispaniola and known from the Massif de la Selle, both in the Dominican Republic and in Haiti. Its natural habitats are mesic pine and broadleaf forests. It is threatened by habitat loss. It is moderately common in suitable habitat, but threatened by habitat loss caused by logging and agriculture. It is known from both La Visite National Park (Haiti) and 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 ... (Dominican Republic), but habitat degradation is occurring in these areas too.

Doris Mable Cochran
Doris Mable Cochran (May 18, 1898 – May 22, 1968) was an American Herpetology, herpetologist and custodian of the American Natural Collection at the Smithsonian Institution in Washington, D.C., for many years. Life Born in North Girard, Pennsylvania, she grew up in Washington, D.C., after her father transferred there for a government job. While an undergraduate student at George Washington University (A.B. 1920, M.S. 1921), she worked for the United States Department of War, War Department and became Aide in the Division of Herpetology at the United States National Museum. Although the museum was under the curatorship of Leonhard Stejneger, Cochran was responsible for the administration of the herpetological collections. In 1927 she became Assistant Curator, and in 1942, Associate Curator just prior to Stejneger's death.

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 ...

Amphibians Of Haiti
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Endemic Fauna Of Hispaniola
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

Eleutherodactylus
''Eleutherodactylus'' is a genus of frogs in the family Eleutherodactylidae.Hedges, S. B., W. E. Duellman, and M. P. Heinicke . 2008. New World direct-developing frogs (Anura: Terrarana): molecular phylogeny, classification, biogeography, and conservation. Zootaxa 1737: 1-182. Many of the 200 species of the genus are commonly known as "rain frogs" or "robber frogs", due to their sharp, high-pitched, insect-like calls. The best-known species is the common coquí (''E. coqui''), which is both a national symbol of Puerto Rico and a notorious invasive species in Hawaii. Two ''Eleutherodactylus'' species, '' E. limbatus'' and '' E. iberia'', are among the smallest known frogs, measuring only 8.5 mm in length (only slightly larger than ''Paedophryne amauensis'', which measures around 7.7 mm). Etymology The name "Eleutherodactylus" is derived from the Greek words for ‘free-toed’, composed of the Ancient Greek ' (, ‘free, unbound’) and ' (, ‘finger, toe’). Most sp ...

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 ...

La Visite National Park
La Visite National Park (french: Parc National La Visite) is one of the two largest national parks of the Republic of Haiti. La Visite is a part of the Massif de la Selle mountain range. Its highest peak is 2275 meters in elevation. The park covers approximately 11,419 hectares of land with 1897 hectares above 2000 meters in elevation, and consists mainly of pine forest, grasslands, and some montane broadleaf forest at an altitude above . The Haitian government established the La Visite National Park in 1983. The capital, Port-au-Prince, is only 22 kilometers north from the park. The northern boundary of La Visite National Park is the east-west running escarpment of the Massif de la Selle. Vegetation The park's vegetation is broadleaf forest, grasslands and pine trees. The Hispaniolan Pine (''Pinus occidentalis'') is the most widespread tree in the park. Other type of forests that cover the park include karst broadleaf and wet broadleaf montane. Avifauna The park offers excel ...

Mesic Habitat
In ecology, a mesic habitat is a type of habitat with a moderate or well-balanced supply of moisture, e.g., a mesic forest, a temperate hardwood forest, or dry-mesic prairie. Mesic habitats transition to xeric shrublands in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat. The others are xeric and hydric. Further examples of mesic habitats include streamsides, wet meadows, springs, seeps, irrigated fields, and high elevation habitats. These habitats effectively provide drought insurance as land at higher elevations warms due to seasonal or other change. Healthy mesic habitats act like sponges in that they store water in such a way that it can be deposited to neighboring habitats as needed. They are common in dryer regions of the western United States, and can be a good water source to neighboring desert habitats. Healthy mesic habitats also provide forb and insects for organisms belonging t ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ...

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 interior ...
