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] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleutherodactylidae
The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under the common name rain frogs. Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species (as of 2014, 206 or 207 species). Eleutherodactylid frogs vary considerably in size, from the minuscule ''Eleutherodactylus iberia'' (female snout–vent length ) to the relative giant '' E. inoptatus'' (female snout–vent length ). Except for the ovoviviparous '' E. jasperi'', these frogs have direct development: no free-living tadpole stage exists; instead, eggs develop directly into small froglets. Subfamilies and genera The two subfamilies and four genera are: * Eleutherodactylinae Lutz, 1954 (216 species) ** ''Diasporus'' Hedges, Duell ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artibonite (department)
Artibonite ( French) or Latibonit (Haitian Creole) is one of the ten departments of Haiti located in central Haiti. With an area of 4,887 km2 it is Haiti's largest department. As of 2015, its estimated population was 1,727,524. The region is the country's main rice-growing area. The main cities are Gonaïves (the capital) and Saint-Marc. In February 2004 an insurgency tried unsuccessfully to declare Artibonite's independence. Etymology The name L'Artibonite is derived from the Artibonite River the longest river on the Quisqueya island. L'Artibonite is derived from the Taino worJa'tibonicu'meaning The Great High Place of the Sacred Waters. Under Toussaint's administration of the island, the department was known as Toussaint's Department. History Taino Period During that period the actual department seats between the three casicas of Marien, Maguana, and Xaragua. The border between those chiefdoms is assumed to be the Artibonite River. Although the department's capital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haiti
Haiti (; ht, Ayiti ; French: ), officially the Republic of Haiti (); ) and formerly known as Hayti, is a country located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean Sea, east of Cuba and Jamaica, and south of The Bahamas and the Turks and Caicos Islands. It occupies the western three-eighths of the island which it shares with the Dominican Republic. To its south-west lies the small Navassa Island, which is claimed by Haiti but is disputed as a United States territory under federal administration."Haiti" ''Encyclopædia Britannica''. Haiti is in size, the third largest country in the Caribbean by area, and has an estimated population of 11.4 million, making it the most populous country in the Caribb ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

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 ...

Small-scale Agriculture
A smallholding or smallholder is a small farm operating under a small-scale agriculture model. Definitions vary widely for what constitutes a smallholder or small-scale farm, including factors such as size, food production technique or technology, involvement of family in labor and economic impact. Smallholdings are usually farms supporting a single family with a mixture of cash crops and subsistence farming. As a country becomes more affluent, smallholdings may not be self-sufficient, but may be valued for the rural lifestyle. As the sustainable food and local food movements grow in affluent countries, some of these smallholdings are gaining increased economic viability. There are an estimated 500 million smallholder farms in developing countries of the world alone, supporting almost two billion people. Small-scale agriculture is often in tension with industrial agriculture, which finds efficiencies by increasing outputs, monoculture, consolidating land under big agricu ...

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 ...
