Eleutherodactylus Nortoni
The spiny giant frog or Norton's robber frog (''Eleutherodactylus nortoni'') is a species of frog in the family Eleutherodactylidae. It is named after James W. Norton who accompanied Albert Schwartz (zoologist), Albert Schwartz in his 1974 expedition to Hispaniola and collected the holotype. Distribution It is endemic to Hispaniola and known from the Massif de la Hotte, Massif de la Selle, and Sierra de Baoruco, occurring in both the Dominican Republic and Haiti. Description The five adult males in the type series measure in snout–vent length. The colouration is green with darker green, irregular blotches. These blotches become nearly diagonal laterally. The fore- and hindlimbs have subcircular blotches; the thighs have three bars. The Sexual selection in amphibians#Vocal signaling in frogs, male advertisement call is a series of about five rising glissando trills, ending in a semi-whistle. Habitat and conservation The species' natural habitats are sinkhole caves in upland bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Schwartz (zoologist)
Albert Schwartz (September 13, 1923 – October 18, 1992) was an American zoologist who worked extensively with the herpetofauna of Florida and the West Indies, and later with butterflies. One magazine article once dubbed him as one of the "Kings of West Indian Anole Taxonomy". Career Schwartz obtained his PhD from the University of Michigan in mammalogy in 1952. Already at that time, he had a keen interest in amphibians and reptiles, as well as in warmer climates. Schwartz spent most of his professional working life at Miami-Dade Community College; he was also supported by a family trust, which he used to fund his own activities as well as field expeditions by others. He was a Research Associate of the Carnegie Museum of Natural History, and also an associate of the Florida Museum of Natural History, the National Museum of Natural History (Smithsonian Institution), and the ''Museo Nacional de Historia Natural'', Santo Domingo, Dominican Republic. Starting in 1954, he worke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1976
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 decline ...

Frogs Of Haiti
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an exte ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pic Macaya National Park
Pic Macaya National Park (french: Parc National Pic Macaya) is one of two national parks of the Republic of Haiti. It is located in the country's southern peninsula, within the Massif de la Hotte. Featuring the country's last stand of virgin cloud forest, it encompasses more than 8,000 hectares. Elevations in the rugged park reach a maximum height of above sea level at Pic Macaya (''Macaya Peak''), the second highest point in Haiti behind Pic la Selle. A majority of the park is composed of two tall peaks: Pic Macaya and Pic Formon. The park was founded in 1984, under the administration of Jean-Claude Duvalier. Originally composed of about 2,000 hectares, the park was expanded to more than 8,000 hectares in March 2013 as part of the Macaya Project. In December 2012, $12 million was pledged through 2017 in agreements with several international development agencies, including the Inter-American Development Bank and the Norwegian Agency for Development Cooperation.

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 ...
