Ecuadorian Little Yellow Bat
''Rhogeessa velilla'', also called the Ecuadorian little yellow bat, is a species of vesper bat in the genus ''Rhogeessa''. It is found in Northwestern Peru and parts of Ecuador. The species was previously included in '' R. io'', but is now recognized as a separate species. Very little is known about this species, though it is generally considered to be insectivorous. Taxonomy ''Rhogeessa velilla'' was described as a new species in 1903 by British zoologist Oldfield Thomas. The holotype was collected by Perry O. Simons on Puná Island in 1898. In 1958, George Gilbert Goodwin published that he considered it a subspecies of the little yellow bat (''R. parvula''). In 1973, R. K. LaVal published that it should instead be considered a subspecies of the black-winged little yellow bat (''R. tumida''). In 1996, Hugh H. Genoways and Robert James Baker elevated Thomas's yellow bat (''R. io'') from a subspecies of the black-winged little yellow bat; ''R. velilla'' was then considered syn ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British imperialism. "You and I in our scientific lives have seen the ...

Karyotype
A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well u ...

Taxa Named By Oldfield Thomas
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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

El Oro Province
El Oro (; ''oro'' = gold) is the southernmost of Ecuador's coastal provinces. It was named for its historically important gold production. Today it is one of the world's major exporters of bananas. The capital is Machala. History The area was settled by the Inca, who inhabited the area at the time Spanish settlement began in 1549. The Spanish found gold there and mined it, carrying the gold to Spain. The province was named for its historically important gold production. The gold was mined by the Spanish mainly in the late 16th and 17th centuries in the village of Zaruma in the Zaruma Canton. In the 18th century, the earthquake of January 1749 destroyed the mining area. A local rebellion stopped the mining until the Spanish agreed to allow the native people to benefit from the mining. Spain imported gold from the area until the area gained its independence from Spain in 1820. Philip II of Spain granted the village the title of "Villa de Sant Antonio del Zerro de Oro de Zaruma" ...

Thomas's Yellow Bat
Thomas's yellow bat (''Rhogeessa io'') is a species of bat from the family Vespertilionidae. Taxonomy Thomas's yellow bat was given its binomial nomenclature by Oldfield Thomas in 1903 as ''Rhogeessa io''. Synonyms for the species include ''Rhogeessa bombyx'' (Thomas, 1913), ''Rhogeessa riparia'' (Goodwin, 1958), and '' Rhogeessa velilla'' (Thomas, 1903). The Thomas's yellow bat was formerly included as a subspecies of the black-winged little yellow bat, but was considered distinct in 1996. The species needs taxonomic review for a number of reasons. One of these reasons includes the possibility that subspecies of the Thomas's yellow bat may be their own species. Range and conservation Thomas's yellow bat is native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Nicaragua, Panama, Suriname, Trinidad and Tobago, and Venezuela. It is listed as "Least Concern" by the IUCN Red List due to its wide distribution, presumed large population, occurrence i ...
