Endangered Mammals Of India
Endangered mammals of India are the mammal species in India that are listed as threatened in the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Animals Background In India, mammals comprise 410 species, 186 genera, 45 families and 13 orders of which nearly 89 species are listed as threatened in the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Animals (IUCN 2006). This includes two species that are locally extinct from India viz. ''Acinonyx jubatus'' and ''Rhinoceros sondaicus''. The mammals are the class of vertebrate animals characterized by the presence of mammary glands, which in females produce milk for the nourishment of young; the presence of hair or fur; specialized teeth; the presence of a neocortex region in the brain; and endothermic or "warm-blooded" bodies. The brain regulates endothermic and circulatory system, including a four-chambered heart. Mammals e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature And Natural Resources
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] |
Neocortex
The neocortex, also called the neopallium, isocortex, or the six-layered cortex, is a set of layers of the mammalian cerebral cortex involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning and language. The neocortex is further subdivided into the true isocortex and the proisocortex. In the human brain, the neocortex is the largest part of the cerebral cortex (the outer layer of the cerebrum). The neocortex makes up the largest part of the cerebral cortex, with the allocortex making up the rest. The neocortex is made up of six layers, labelled from the outermost inwards, I to VI. Etymology The term is from ''cortex'', Latin, " bark" or "rind", combined with ''neo-'', Greek, "new". ''Neopallium'' is a similar hybrid, from Latin ''pallium'', "cloak". ''Isocortex'' and ''allocortex'' are hybrids with Greek ''isos'', "same", and ''allos'', "other". Anatomy The neocortex is the most developed in its organisat ...

Banteng
The banteng (''Bos javanicus''; ), also known as tembadau, is a species of cattle found in Southeast Asia. The head-and-body length is between . Wild banteng are typically larger and heavier than their domesticated counterparts, but are otherwise similar in appearance. The banteng shows extensive sexual dimorphism; adult bulls are generally dark brown to black, larger and more sturdily built than adult cows, which are thinner and usually pale brown or chestnut red. There is a big white patch on the rump. Horns are present on both sexes, and are typically long. Three subspecies are generally recognised. Banteng are active during the day as well as at night, though activity at night is more in areas frequented by humans. Herds comprise two to forty individuals, and generally a single bull. Herbivores, banteng feed on vegetation such as grasses, sedges, shoots, leaves, flowers and fruits. Banteng can survive without water for long stretches during droughts, but drink regularly i ...

Bengal Tiger
The Bengal tiger is a population of the ''Panthera tigris tigris'' subspecies. It ranks among the biggest wild cats alive today. It is considered to belong to the world's charismatic megafauna. The tiger is estimated to have been present in the Indian subcontinent since the Late Pleistocene, for about 12,000 to 16,500 years. Today, it is threatened by poaching, Habitat loss, loss and Habitat fragmentation, fragmentation of habitat, and was estimated at comprising fewer than 2,500 wild individuals by 2011. None of the ''Tiger Conservation Landscapes'' within its range is considered large enough to support an effective population of more than 250 adult individuals. The Bengal tiger's historical range covered the Indus River valley until the early 19th century, almost all of India, Pakistan, southern Nepal, Bangladesh, Bhutan and southwestern China. Today, it inhabits India, Bangladesh, Nepal, Bhutan and southwestern China. India's tiger population was estimated at 2,603–3,346 ...

Dhole
The dhole (''Cuon alpinus''; ) is a canid native to Central, South, East and Southeast Asia. Other English names for the species include Asian wild dog, Asiatic wild dog, Indian wild dog, whistling dog, red dog, red wolf, and mountain wolf. It is genetically close to species within the genus ''Canis'', but distinct in several anatomical aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars sport only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, Europe and North America but became restricted to its historical range 12,000–18,000 years ago. The dhole is a highly social animal, living in large clans without rigid dominance hierarchies and containing multiple breeding females. Such clans usually consist of about 12 individuals, but groups of over 40 are known. It is a diurnal pack hunter which preferentially targets large and medium-sized ungulates. I ...

Asiatic Lion
The Asiatic lion is a population of ''Panthera leo leo'' that today survives in the wild only in India. Since the turn of the 20th century, its range has been restricted to Gir National Park and the surrounding areas in the Indian state of Gujarat. Historically, it inhabited much of southwest Asia to northern India. The first scientific description of the Asiatic lion was published in 1826 by the Austrian zoologist Johann N. Meyer, who named it ''Felis leo persicus''. On the IUCN Red List, it is listed under its former scientific name ''Panthera leo persica'' as Endangered because of its small population size and area of occupancy. Until the 19th century, it occurred in Saudi Arabia, eastern Turkey, Iran, Mesopotamia, Pakistan, and from east of the Indus River to Bengal and the Narmada River in Central India. The population has steadily increased since 2010. In May 2015, the 14th Asiatic Lion Census was conducted over an area of about ; the lion population was estimated at 523 ...

Asiatic Golden Cat
The Asian golden cat (''Catopuma temminckii'') is a medium-sized wild cat native to the northeastern Indian subcontinent, Southeast Asia and China. It has been listed as Near Threatened on the IUCN Red List since 2008, and is threatened by poaching and habitat destruction, since Southeast Asian forests are undergoing the world's fastest regional deforestation. The Asian golden cat's scientific name honours Coenraad Jacob Temminck. It is also called Temminck's cat and Asiatic golden cat. Taxonomy ''Felis temmincki'' was the scientific name used in 1827 by Nicholas Aylward Vigors and Thomas Horsfield who described a reddish brown cat skin from Sumatra. ''Felis moormensis'' proposed by Brian Houghton Hodgson in 1831 was a young male cat caught alive by Moormi hunters in Nepal. ''Felis tristis'' proposed by Alphonse Milne-Edwards in 1872 was a spotted Asian golden cat from China. It was subordinated to the genus ''Catopuma'' proposed by Nikolai Severtzov in 1853.

Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically moder ...

Heart
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
