Sphaerodactylus Nicholsi
''Sphaerodactylus nicholsi'', also known commonly as Nichols least gecko, Nichols dwarf sphaero or the Puerto Rican crescent sphaero, is a species of lizard in the family Sphaerodactylidae . The species is endemic to Puerto Rico. Etymology The specific name, ''nicholsi'', is in honor of American ichthyologist John Treadwell Nichols.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Sphaerodactylus nicholsi'', p. 190). Habitat The preferred habitats of ''S. nicholsi'' are forest, shrubland, and marine intertidal, but it may also be found in introduced vegetation. Reproduction ''Sphaerodactylus nicholsi'' is oviparous. References Further reading *Grant C (1931). "The sphaerodactyls of Porto Rico, Culebra and Mona Islands".

Intertidal Zone
The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life, such as sea stars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or '' seashore'', although those can be defined as a wider region. The intertidal zone also includes steep rocky cliffs, sandy beaches, bogs or wetlands (e.g., vast mudflats). This area can be a narrow strip, such as in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in the intertidal zone are well-adapted to their environment, facing high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Puerto Rico
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Reptiles Of Puerto Rico
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Sphaerodactylus
''Sphaerodactylus'' is a genus of geckos from the Americas that are distinguished from other Gekkota by their small size, by their round, rather than vertical, eye pupils, and by each digit terminating in a single, round adhesive pad or scale, from which their name (''Sphaero'' = round, ''dactylus'' = finger) is derived. All species in this genus are rather small, but two species, '' S. ariasae'' and '' S. parthenopion'', are tiny, and – with a snout-vent length of about – the smallest reptiles in the world. Fossil record Fossil remains referred to ''Sphaerodactylus'' have been recovered from Dominican amber. Species The following 108 species are recognized as being valid. *'' Sphaerodactylus alphus'' - Guanaja large-scaled geckolet *'' Sphaerodactylus altavelensis'' - Alto Velo least gecko, Alto Velo sphaero *'' Sphaerodactylus argivus'' - Cayman least gecko *'' Sphaerodactylus argus'' - ocellated gecko, ocellated sphaero, stippled sphaero *''Sphaerodactylus ariasae' ...

Carnegie Museum Of Natural History
The Carnegie Museum of Natural History (abbreviated as CMNH) is a natural history museum in the Oakland (Pittsburgh), Oakland neighborhood of Pittsburgh, Pennsylvania. It was founded by List of people from the Pittsburgh metropolitan area, Pittsburgh-based industrialist Andrew Carnegie in 1896. Housing some 22 million specimens, the museum features one of the most extensive paleontological and entomological collections in the world. Description and history The museum consists of organized into 20 galleries as well as research, library, and office space. It holds some 22 million specimens, of which about 10,000 are on view at any given time and about 1 million are cataloged in online databases. In 2008 it hosted 386,300 admissions and 63,000 school group visits. Museum education staff also actively engage in outreach by traveling to schools all around western Pennsylvania. The museum gained prominence in 1899 when its scientists unearthed the fossils of ''Diplodocus carnegi ... [...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.

Oviparity
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or f ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...
