Alexander Grant Ruthven
Alexander Grant Ruthven (April 1, 1882 – January 19, 1971) was a herpetologist, zoologist and the President of the University of Michigan from 1929 to 1951. Biography Alexander Grant Ruthven was born in 1882 in Hull, Iowa. He graduated from Morningside University, Morningside College in 1903. In 1906, he received a Ph.D. in zoology from the University of Michigan. He worked as a professor, director of the University Museum, and Dean. He became the President in 1929. As such, he promoted a corporate administrative structure. He also approved of police raids against rum-running, bootleggers at fraternities. He was elected to the American Philosophical Society in 1931. He retired in 1951, and died in 1971. He is buried at Forest Hill Cemetery (Ann Arbor, Michigan), Forest Hill Cemetery which is adjacent to the university. The work of Ruthven on the familiar garter snakes, published in 1908, may regarded as founding an essentially new school of herpetology in the United States. T ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphaerodactylidae
The Sphaerodactylidae are a Family (biology), family of geckos (Gekkota) distributed in North America, Central America, South America, and the Caribbean, as well as in Southern Europe, North Africa, the Middle East, and into Central Asia. The family contains 12 living genera and over 200 living species. The family name comes from the ball shape of their finger joints.

Endemic
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 bec ...

Magdalena Department
Magdalena () is a Departments of Colombia, department of Colombia, located in the north of the country by the Caribbean Sea, with more than 1.3 million people.

Pseudogonatodes
''Pseudogonatodes'' is a genus of sphaerodactylid geckos, often known as South American clawed geckos, containing seven described species. Like most sphaerodactylines (South American sphaerodactylids), ''Pseudogonatodes'' are miniaturized geckos and among the smallest living lizards. They are diurnal and terrestrial, foraging among leaf litter and rotting wood on the ground. Prey items are primarily small arthropods such as springtails, insect larvae, and orthopterans (crickets and kin). Though locally common and not strongly threatened with extinction, most species occupy restricted ranges in remote tropical forests. The most widespread and well-studied species, '' Pseudogonatodes guianensis'', is found throughout the Amazon rainforest.

Taxa Named By Alexander Grant Ruthven
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
