Eleutherodactylus Parabates
''Eleutherodactylus parabates'', also known as Independencia robber frog and Neiba whistling frog, is a species of frog in the family Eleutherodactylidae. It is endemic to Hispaniola and found along the crest of the , near the border between the Dominican Republic and Haiti. The specific name ''parabates'' is Greek for "transgressor" and refers to this species being the first Hispaniolan member of the "''Eleutherodactylus dimidiatus'' species group" recorded north of the Plain of the Cul-de-Sac–Valle de Neiba (the southern species are ''Eleutherodactylus jugans'' and '' E. ventrilineatus''). Description Adult females measure and adult males, based on a single specimen, in snout–vent length. The snout is rather pointed. The tympanum is relatively large. The fingers and toes have moderately well-developed discs but lack webbing. The dorsal coloration consists of a brown longitudinal band running from the snout to the groin; some individuals have a median tan dorsal line. Th ...

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 wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Because tails are often missing or absent, especially in juveniles, SVL is seen as more invariant than total length. Even in the case of crocodiles, tail tips may be missing. Methods The measurements may be taken with dial calipers or digital calipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Albert Schwartz (zoologist)
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 dramat ...

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 ...

Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte '' Tillandsia'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 obje ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum wo ...

Frog
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 ...
