Ozimops Lumsdenae
''Ozimops lumsdenae'' is a species of molossid bat found in Australia, the largest of the genus ''Ozimops''. Taxonomy It is a species of genus ''Ozimops'', both taxa emerging in the publication of new species and generic combinations of mostly Australian molossid bats. Prior to this, an analysis of populations in the regions in 1988 had identified this group as ''Mormopterus'' species 1'. Specimens have previously been described as '' Mormopterus beccarii'', at least in part.. The generic combination of this species was inferred by the elevation of a subgenus to genus ''Ozimops''. The first publication of the species was in 2014, allying it to a subgenus of the group under revision as ''Mormopterus'' (''Ozimops'') ''lumsdenae''. The synonymy of the new species was recognised as, * ''Mormopterus'' species 1 Adams et al. 1988 * ''Mormopterus beccarii'' Peters, 1881 * ''Mormopterus beccarii astrolabiensis'' Meyer, 1899 The type specimen, a male, was obtained on 13 September 2002 ...

Molossid
The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels. Common ancestry The family's scientific name comes from the type genus '' Molossus'', which in turn is from the Molossus breed of dogs. The family's common name is derived from a length of "free" tail, projecting beyond the end of the uropatagium—the membrane that connects the base of the tail to the hi ...

Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formations, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 2014
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saurops ...

Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% ...

IUCN Redlist
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species 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 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozimops Petersi
''Ozimops petersi'', the inland free-tailed bat is a species of bat found in Australia. It is notable for being able to tolerate the most extreme body temperature range of any known mammal. Taxonomy It was initially described in 1884 by Swedish zoologist Dr. Wilhelm Leche. Leche had acquired a collection of specimens from Gustav Schneider, a Swiss natural history dealer, and used to describe a new species that was distinguishable from the rest of the series. In 1906, Oldfield Thomas published a paper in which he considered ''N. petersi'' as synonymous with an earlier description of species ''Mormopterus planiceps'' ('' Ozimops planiceps'', in part). This status was largely maintained until 2014, although greater diversity had previously been identified, when a study examining the morphology and genetics of the bats of Australia showed that it was distinct enough to be considered a full species. This description removed the name from a synonymy of ''M. planiceps'', publishin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozimops Halli
''Ozimops halli'', also referred to as the Cape York free-tailed bat, is a species of molossid bat found at the Cape York Peninsula in Australia. Taxonomy A species of genus ''Ozimops'', both taxa emerging in the publication of new species and generic combinations of mostly Australian molossid bats. Prior to this, an analysis of populations in the regions in 1988 had identified this group as ''Mormopterus'' species 5 (populations S and T)'. Specimens have previously been described as '' Mormopterus ridei'', at least in part, or other uncertainty in paraphyletic groups once referred to as the ''planiceps'' complex. The generic combination of this species was inferred by the elevation of a subgenus to genus ''Ozimops''. The first publication of the species was in 2014, allying it to a subgenus of the group under revision as ''Mormopterus'' (''Ozimops'') ''halli''. The common names also include Cape York free-tailed bat. The type specimen, a male, was obtained on 7 November 2006 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozimops Cobourgianus
''Ozimops cobourgianus'' is a species of molossid bat, insectivorous flying mammals known as freetail bats, which are found in north and west coastal regions of Australia. First described in 1959, the group were later recognised as species ''Mormopterus cobourgianus'' and soon placed with a new genus. They are associated with mangrove habitat and roost in the hollows of those trees, and known to seek food there and in eucalypt or melaleuca woodland or other coastal habitat. A smaller bat of genus ''Ozimops'', ''O. cobourgianus'' are around fifty millimetres (two inches) long and weigh six to ten grams. Little is known of their habits. Taxonomy A species of genus ''Ozimops'', established to separate new species and generic combinations of mostly Australian molossid bats. The population has been described as subspecies ''Tadarida loriae cobourgiana'' by David H. Johnson in 1959, the result of examination of mammal specimens the author collected on a 1948 scientific expedition bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ozimops Ridei
''Ozimops ridei'' is a species of molossid bat found in eastern Australia. Taxonomy and etymology A species of genus ''Ozimops'', established to separate new species and generic combinations of Australian molossid bats. The population has been described as a subspecies of '' Mormopterus loriae'', Loria's mastiff bat. In 2008, it was elevated for the first time to species rank—a view that was further corroborated in 2014 when a review of systematics and morphological characters of Australian ''Mormopterus'' was published. The generic combination of this species was inferred by the elevation of the subgenus to genus ''Ozimops''. The eponym for the species name "''ridei''" is likely William Ride, who was an accomplished Australian zoologist. Description It is a smaller member of its genus, with a body mass of . Its forearm is long. Fur color is highly variable among individuals, with some bats a light brownish-gray while others are darker brown. Biology and ecology It is n ...

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not ...
