Trident Bat
The trident bat or trident leaf-nosed bat (''Asellia tridens'') is a species of bat in the family Hipposideridae. It is widely distributed in the West, South and Central Asia, and North, East, and Central Africa. Its natural habitats are subtropical or tropical dry forests, dry savanna, subtropical or tropical dry shrubland, caves and hot deserts. Description Individuals weigh and have forearm lengths of approximately . Taxonomy The trident bat was described as a new species in 1813 by French naturalist Étienne Geoffroy Saint-Hilaire. Geoffroy placed it in the genus '' Rhinolophus'', with a scientific name of ''Rhinolophus tridens''. Biology After a gestation length of 10 weeks, females give birth in a three-week period in the end of June and beginning of July. The litter size for each female is one offspring, called a pup. Pups are relatively large at birth, weighing up to 30% of their mothers' weights (). Though hairless at birth with closed eyes, a sign of altricial o ...

Rhinonycteridae
Rhinonycteridae is a family of bats, within the suborder Yinpterochiroptera. The type species, the orange nose-leafed species group ''Rhinonicteris aurantia'', is found across the north of Australia. Description The family accords with the description to the type genus ''Rhinonicteris'', and its classification of the morphology of the rhinarium. The revision of Hill in 1982 follows Gray to describe the features of the nose-leaf for the subfamilial group, and these provide diagnosis to distinguish the species from other families. Molecular analysis also provides a distinctive retrotransposon insertion expressed in a gene fragment. Taxonomy The alliance resurrects John Edward Gray's 1866 arrangement of known microbat taxa, first published as subtribe Rhinonycterina, and elevating this to the taxonomic rank, rank of family. The taxon combined the poorly known genera ''Cloeotis'' and ''Triaenops'' in a 1982 revision that compared the nose-leaf morphology of the species. This name ...

Pharaoh Eagle-owl
The Pharaoh eagle-owl (''Bubo ascalaphus'') is a Middle Eastern and North African species of owl in the family Strigidae. Description The Pharaoh eagle-owl has a mottled plumage and large orange-yellow eyes. The head and upperparts are tawny and densely marked with black and creamy-white streaks and blotches, while the underparts are pale creamy-white, with black streaks on the upper breast and fine reddish-brown vermiculations on the lower breast and belly. The face has the disc-like form typical of most owls, defined by a dark rim, the robust bill is black and hooked, and the head is crowned with small ear tufts. With a body length of , it is one of the smaller eagle-owl species. Two subspecies have been named, ''B. a. ascalaphus'' and ''B. a. desertorum'', the latter formerly cited as being smaller and paler with sandier colour; they are no longer accepted as distinct, as the variation is continuous and without geographic basis, so the species now regarded as monotypic.

Taxa Named By Étienne Geoffroy Saint-Hilaire
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] |
Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Mammals Described In 1813
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews).

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...
