Nilgiri Marten
The Nilgiri marten (''Martes gwatkinsii'') is the only marten species native to southern India. It lives in the hills of the Nilgiris and parts of the Western Ghats. With only around a thousand members left it is listed as Vulnerable on the IUCN Red List. Taxonomy The Nilgiri marten was described by Thomas Horsfield based on a skin in the museum of the East India Company; it is named after the collector Reynolds Gwatkins. Characteristics The Nilgiri marten is deep brown from head to rump, with the forequarters being almost reddish, with a bright throat ranging in colour from yellow to orange. It has a prominent frontal concavity and is larger than the yellow-throated marten. It is about long from head to vent and has a tail of . It weighs about . Distribution and habitat The Nilgiri marten mainly inhabits the shola grasslands and South Western Ghats montane rain forests, and occasionally the adjacent South Western Ghats moist deciduous forests and commercial plantat ...

Thomas Horsfield
Thomas Horsfield (May 12, 1773 – July 24, 1859) was an American physician and natural history, naturalist who worked extensively in Indonesia, describing numerous species of plants and animals from the region. He was later a curator of the East India Company Museum in London. Early life Horsfield was born in Bethlehem, Pennsylvania, and studied medicine at the University of Pennsylvania. He was the grandson of Timothy Horsfield, Sr. (1708-1773), who was born in Liverpool and emigrated to New York in 1725. The Horsfield family converted from the Church of England to Moravianism, a Protestant denomination with a strong emphasis on education. In 1748, he moved his family to Bethlehem, Pennsylvania and joined them the next year. Horsfield's father was Timothy Horsfield, Jr. and he married Juliana Sarah Parsons in 1738. Thomas Horsfield was born in Bethlehem on May 12, 1773. He was educated at the Moravian schools in Bethlehem and Nazareth, Pennsylvania, Nazareth. He studied medicin ...

Mammals Of Tamil Nadu
There are more than 2000 species of fauna in Tamil Nadu. This rich wildlife is attributed to the diverse relief features as well as favorable climate and vegetation in the Indian state. Recognizing the state's role in preserving the current environment, the state government has established several wildlife and bird sanctuaries as well as national parks, which entail stringent protective measures. Tamil Nadu is also included in the International Network of Biosphere Reserves, which facilitates international recognition and additional funding. There are five national parks and 17 wildlife sanctuaries that serve as homes to the wildlife. Mammals Tamil Nadu is known for the diversity of its mammals due to the varying environments that sustain both dry and moist deciduous forests. Notable species include arboreal animals distributed in its hills, grasslands, mangroves, scrubs and forests. These also include vulnerable species like the Bengal tiger, Nilgiri tahr, and the lion-tail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of India
This list of mammals of India comprises all the mammal species alive in India today. Some of them are common to the point of being considered vermin while others are exceedingly rare. Many species are known from just a few zoological specimens in museums collected in the 19th and 20th centuries. Many of the carnivores and larger mammals are restricted in their distribution to forests in protected areas, while others live within cities in the close proximity of humans. They range in size from the Eurasian pygmy shrew (''Sorex minutus'') to the Asian elephant (''Elephas maximus''). They include nocturnal small mammals endemic to India such as the Malabar large-spotted civet (''Viverra civettina''). While the status of many of these species is unknown, some are definitely extinct. Populations of many carnivores are threatened. The tiger (''Panthera tigris''), dhole (''Cuon alpinus''), and Malabar large-spotted civet (''Viverra civettina'') are some of the most endangered carnivore spe ...

Martens
A marten is a weasel-like mammal in the genus ''Martes'' within the subfamily Guloninae, in the family (biology), family Mustelidae. They have bushy tails and large paws with partially retractile claws. The fur varies from yellowish to dark brown, depending on the species; it is valued by Animal trapping, animal trappers for the fur trade. Martens are slender, agile animals, which are adapted to living in the taiga, and inhabit coniferous and northern deciduous forests across the Northern Hemisphere. Classification Results of DNA research indicate that the genus ''Martes'' is paraphyletic, with some studies placing ''Martes americana'' outside the genus and allying it with ''Tayra, Eira'' and ''Gulo'', to form a new New World clade. The genus first evolved up to seven million years ago during the Miocene epoch. Fossils Several fossil martens have been described, including: *†''Martes campestris'' (Pliocene) *†''Martes wenzensis'' (Pliocene) *†''Martes ...

Cicada
The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species Taxonomy (biology)#Taxonomic descriptions, described from around the world; many species remain Undescribed taxon, undescribed. Nearly all cicada species are annual cicadas with the exception of the few North American periodical cicada species, genus ''Magicicada'', which in a given region emerge en masse every 13 or 17 years. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drum-like tymbals. The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prey
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunistic or omnivorous and only practice predation occasionally. Most obligate carnivores are specialized for hunting. They may ha ...

Omnivorous
An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. ...

Arboreal
Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species. Cartmill, M. (1985). "Climbing". pp. 73–88 ''In'': Hildebrand, Milton; Bramble, Dennis M.; Liem, Karel F.; Wake, David B. (editors) (1985). ''Functional Vertebrate Morphology''. Cambridge, Massachusetts: Belknap Press. 544 pp. . Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as tree snails. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in ...

Diurnal Animal
Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
