Sahyadris Forest Rat
The Sahyadris forest rat (''Rattus satarae'') is a species of rat belonging to the family Muridae. It is native to the northern Western Ghats in India where it is split between three regions, Satara in Maharashtra, the Nilgiri mountains in Tamil Nadu and Kodagu district in Karnataka. Vulnerability ''R. satarae'' is listed as vulnerable by the IUCN due to it being restricted to less than 2,000 km2 of forest habitat that remains. The locations it is found in are highly fragmented and it is vulnerable to changes in its habitat. The species is facing a decline in the quality of its habitat and the number of mature individuals in the population. It is highly sensitive to changes in its habitat. The main threats faced by the species include loss of forests to plantations, logging, pesticide use, and planting of exotic species. Habitat The species has only been seen in the moist deciduous and evergreen forests of the northern Western Ghats are of India, between 700 and 2,150& ...

Martin Hinton
Martin Alister Campbell Hinton FRS (29 June 1883 – 3 October 1961) was a British zoologist. Career Hinton joined the staff of the Natural History Museum in 1910, working on mammals, in particular rodents. He became Deputy Keeper of Zoology in 1927 and Keeper in 1936, retiring in 1945. Hinton is among those associated with the Piltdown Man The Piltdown Man was a paleoanthropological fraud in which bone fragments were presented as the fossilised remains of a previously unknown early human. Although there were doubts about its authenticity virtually from the beginning, the remains ... hoax, a composite of an altered human skull and ape jawbone planted, and subsequently 'discovered', at a dig in Piltdown, England, and presented as a missing link between man and ape.

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas '' homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to parallel evo ...

Endemic Fauna Of The Western Ghats
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodents Of India
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose ...

Rats Of Asia
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include ''Neotoma'' ( pack rats), ''Bandicota'' (bandicoot rats) and ''Dipodomys'' ( kangaroo rats). Rats are typically distinguished from mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms ''rat'' and ''mouse'' are not taxonomically specific. There are 56 known species of rats in the world. Species and description The best-known rat species are the black rat (''Rattus rattus'') and the brown rat (''Rattus norvegicus''). This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over in the wild. The term ''rat'' is also used in the names of other small mammals th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rattus
''Rattus'' is a genus of muroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus. Species and description The best-known ''Rattus'' species are the black rat (''R. rattus'') and the brown rat (''R. norvegicus''). The group is generally known as the Old World rats or true rats and originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over in the wild. Taxonomy of ''Rattus'' The genus ''Rattus'' is a member of the giant subfamily Murinae. Several other murine genera are sometimes considered part of ''Rattus'': ''Lenothrix'', ''Anonymomys'', ''Sundamys'', ''Kadarsanomys'', ''Diplothrix'', ''Margaretamys'', ''Lenomys'', ''Komodomys'', ''Palawanomys'', ''Bunomys'', ''Nesoromys'', ''Stenomys'', ''Taeromys'', ''Paruromys'', ''Abditomys'', ''Tryphomys'', ''Limnomys'', ''Tarsomys'', '' Bullimus'', ''Apomys'', ''Millardia'', '' Srilankamys'', ''Niviventer'', ''Maxomy ...

Ecological Niche
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

Muridae
The Muridae, or murids, are the largest family of rodents and of mammals, containing approximately 1,383 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia. The name Muridae comes from the Latin ' (genitive '), meaning "mouse", since all true mice belong to the family, with the more typical mice belonging to the genus '' Mus''. Distribution and habitat Murids are found nearly everywhere in the world, though many subfamilies have narrower ranges. Murids are not found in Antarctica or many oceanic islands. Although none of them are native to the Americas, a few species, notably the house mouse and black rat, have been introduced worldwide. Murids occupy a broad range of ecosystems from tropical forests to tundras. Fossorial, arboreal, and semiaquatic murid species occur, though most are terrestrial animals. The extensive list of niches filled by murids helps to explain their relative abundance. Diet and dentiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Western Ghats Moist Deciduous Forests
The North Western Ghats moist deciduous forests is a tropical moist broadleaf forest ecoregion of southwestern India. Geography The North Western Ghats moist deciduous forests lies in the northern portion of the Western Ghats (Sahyadri) range. It extends from southeastern Gujarat through Dadra and Nagar Haveli, Maharashtra, Goa, and Karnataka. It covers the eastern and western slopes of the range between 250 and 1000 meters elevation, and surrounds the North Western Ghats montane rain forests ecoregion, which lies above 1000 meters elevation. The ecoregion has an area of . It is bounded on the west by the Malabar Coast moist forests ecoregion, which lies between the 250 meter elevation and the Arabian Sea. At its northern end, the ecoregion extends to the Narmada River, and borders the Khathiar-Gir dry deciduous forests to the northwest and the Narmada Valley dry deciduous forests to the northeast. The Wayanad forests at the southern end of the ecoregion mark the transition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, includin ...
