Strecker's Pocket Gopher
''Geomys streckeri'', also known as Strecker's pocket gopher, is a species of pocket gopher found in Texas. It was formerly considered a subspecies of the Texas pocket gopher. Chromosomal analyses have proven this species to be distinct. Analysis of its mitochondrial cytochrome b points to this species being a sister clade to '' Geomys personatus'', '' Geomys attwateri'', and ''Geomys tropicalis''. Other evidence, using a Bayesian analysis of ribosomal RNA and certain proteins Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, re ..., points to it being embedded within the ''G. personatus'' clade and being a sister species to ''G. attwateri''. It is named after John Kern Strecker, an American herpetologist and namesake of the Strecker Museum. References Endemic rodents of the Unite ...

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] |
Geomys Tropicalis
The tropical pocket gopher (''Geomys tropicalis'') is a species of rodent in the family Geomyidae. It is endemic to Mexico. Its natural habitat is hot deserts. It is threatened by habitat loss. Description The tropical pocket gopher is cinnamon to brown on its back and head. Its underparts have white fur, and its tail is mostly naked. They have large front feet, along with small eyes and a thick body. Males are on average larger than females. Distribution and habitat The distribution of the tropical pocket gopher is restricted to a small area of the Veracruz moist forests, near the southeastern corner of Tamaulipas, Mexico. Genetics The tropical pocket gopher has a diploid number of 38. This is low compared to similar species. This could help them adapt to their restricted habitat. Since their numbers are low there is a high risk of them losing too much genetic variability to survive.Davis et al. 1971. Chromosomal studies of Geomys. Jour. Mammal.52:617-620. References Tr ...

Endemic Fauna Of Texas
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 ...

Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid ...

Ribosomal RNA
Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes. Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form SSU rRNA, small and LSU rRNA, large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and Translation (biology), translate the latter into proteins. Ribosomal RNA is the predominant form of RNA found in most cells; it makes up about 80% of cellular RNA despite never being translated into proteins itself. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins, though this ratio differs between Prokaryote, prokaryotes and Eukaryote, eukaryotes. Structure Although the primary structure of rRNA sequences can vary across organisms, Base pair, base-pairing within these sequ ...

Pocket Gopher
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 speciesSearch results for "Geomyidae" on thASM Mammal Diversity Database are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens. The name "pocket gopher" on its own may refer to any of a number of genera within the family Geomyidae. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called "gophers", as well. The origin of the word "gopher" is uncertain; the French , meaning waffle, has been suggested, on account of the gopher tunnels resembling the honeycomb-like pattern of holes in a waffle; another suggestion is that the word is of Muskogean origin. Description Pocket gophers weigh around , and are about in body length, with a tail long. A few species reach weights approaching . Within any p ...

Geomys Personatus
The Texas pocket gopher (''Geomys personatus'') is a species of rodent in the family Geomyidae. It is found in Tamaulipas in Mexico and in Texas in the United States. Description Males grow to a length of about including a tail of about . Females are slightly smaller and both sexes weigh about . The dorsal surface is a dull greyish-brown and the ventral surface is whitish with darker patches. There is very little hair on the tail especially near the tip. The upper incisors have a pair of grooves. Distribution The Texas pocket gopher is found in southern Texas as far north as Val Verde County and San Patricio County, and the state of Tamaulipas, the most north-easterly part of Mexico. Its range is patchy and disjointed, similarly to other ''Geomys'' species. It is common in the sand drifts on Mustang and Padre islands in the Gulf of Mexico. The population around Maverick County, Zavala County, and Dimmit County was recently recognized as a distinct species, Strecker's ...

Sister Clade
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...
