The cubs stay with their mother until they reach adulthood at about 2 to 3 years of age (Ward and Kynasaton, 1995; Blomstrom, 2000). Reasons for the destruction include agricultural and developmental plans. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. "Bear Species Descriptions" (On-line). Sanderson, I.
Not much is known about their social systems but evidence suggests they are solitary except for mothers with cubs. Ward, P., S. Kynaston. Sloth bears live mainly in tropical areas. Termites are a very secure food source, as they are present all year round. They are more frequently found at lower elevations and seem to prefer drier forests and areas with rocky outcrops (Ward and Kynaston, 1995; IBA, 1999). While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control.

Bies, L. 2002. Contributor Galleries Projects focused on gene expression profiling of ageing and of dietary manipulations of ageing, such as caloric restriction. breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. They do not hibernate, but do have a period of inactivity during the rainy season (Sanderson, 1972; Ward and Kynaston, 1995; IBA, 1999; Blomstrom, 2000). Sloth bear cubs develop quickly compared to most other bear species: they start walking a month after birth, become independent at 24-36 months, and become reproductively mature at the age of 3 years. They are excellent climbers, but do not climb trees to escape danger. This gave rise to the name "bear sloth." The gall bladders and fat of M. ursinus are used in traditional medicine (Ward and Kynaston, 1995). Behaviour Sloth bears are not territorial and do not appear to be aggressive towards other bears.
Young cubs ride on their mother's back when she walks, runs, or climbs trees until they reach a third of her size. Early explorers observed that M. ursinus hung upside down in trees. Comments, suggestions, ideas, and bug reports are welcome. Sloth bears are mainly nocturnal. October 30, 2001 Blomstrom, D. 2000. © WSPA 2010 | Working towards a world where animal welfare matters and animal cruelty ends. A curated database of genes associated with dietary restriction in model organisms either from genetic manipulation experiments or gene expression profiling. the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south. Bears of the World. Summer 2000. Software for ageing research, including the Ageing Research Computational Tools (ARCT) perl toolkit. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Record longevity in captivity belongs to one wild born female that was 33.3 years of age when she died . Sloth bears are not territorial and do not appear to be aggressive towards other bears. This species is typically black in colour, although occasionally brown or reddish brown. They also have a reputation for being unpredictable and aggressive (although this may be an unfair description) toward humans. Sloth bears: they eat ants, but take on tigers.
Range lifespan Status: captivity 40 (high) years; Average lifespan Status: captivity 30.0 years Max Planck Institute for Demographic Research; Average lifespan Status: captivity 40.0 years Max Planck Institute for Demographic Research; Behavior. Cubs often ride on the mother's back (Ward and Kynaston, 1995). an animal that mainly eats all kinds of things, including plants and animals. Sri Lanka has lost about 1.85 million hectacres of natural high forest between 1956-1983. Adults measure 60 to 90 cm at the shoulder. In other words, India and southeast Asia.
Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Some studies have them mating mostly between May and July, whereas others report mating and giving birth at any tiime of year.
These bears have also been hunted because of their reputation for aggression and crop destruction (Ward and Kynaston, 1995). Taxon Information Information on the reproductive behavior of M. ursinus varies.
Males are not reported to participate in parental care. The interval between litters varies from two to three years. In captivity, a pair only mates for about 1 to 2 days.
The average litter size is two, but occasionally one to three cubs are born in a single litter.
It has been reported that these animals can live up to 40 years in captivity , which has not been verified. Sloth bears will enter crop fields such as maize.
Sloth bears are classified as âVUâ (vulnerable) on the IUCN 2006 Red List â a result of significant population decline across their range associated with the loss of habitat and a decline in its quality. The muzzle is long and grayish-coloured with lips that can be thrust forward and a long, flat tongue.
The breeding season for sloth bears occurs primarily from May to July and births occur mainly from November to January (although have been observed as early as September in Nepal). 1972. HAGR may be freely used for all purposes under some conditions. After a 6-7 month gestation period, Sloth bears normally give birth to a litter of two cubs in an underground den. Sloth bears tend to be very noisy during mating (Blomstrom, 2000). These bears have a light "U" or "Y" shaped patch on their chests. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Distribution The distribution of the species is restricted to the Indian subcontinent, including India, Nepal, Bhutan, Bangladesh and the island of Sri Lanka. Their sense of smell is well developed but their sight and hearing are poor. the area in which the animal is naturally found, the region in which it is endemic. The lifespan of a sloth bear in the wild is estimated to be 20 to 30 years, whereas those in the captivity can live from 30 to 40 years. Surprisingly, these bears are described as shy. When nearby populated areas sloth bears feed on cultivated crops like sugar cane and maize (Ward and Kynaston, 1995; Sanderson, 1972). uses smells or other chemicals to communicate, a substance used for the diagnosis, cure, mitigation, treatment, or prevention of disease. Sloth bear Lifespan, ageing, and relevant traits Maximum longevity 33.3 years (captivity) Source ref. Garden City, New York: Doubleday & Company.
Their shaggy fur does not have an undercoat, so it keeps them relatively cool in their native, warm climate and protects them from tropical insects. This sucking action is also accompanied with a series of puffings and belchings which can be heard up to 185 m away. at http://www.geobop.com/Mammals/Carnivora/Ursidae/Ursus_ursinus/.

Sloth Bear Shaggy, dusty, and unkempt, the reclusive sloth bear makes its home in the forests of South Asia.
Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. The benchmark genome assembly and annotation of the long-lived, cancer-resistant naked mole-rat (Heterocephalus glaber). For example, they live in the tropics but have long, dark, shaggy coats suggesting they are susceptible to cold stress. Studies focused on cancer, in particular using genomics and bioinformatics approaches.
They can be found in forested areas and grasslands. Record longevity in captivity belongs to one wild born female that was 33.3 years of age when she died [0671]. The distribution of the species is restricted to the Indian subcontinent, including India, Nepal, Bhutan, Bangladesh and the island of Sri Lanka.

The sloth bear is medium sized bear; adult males average 80â145 kg, while females usually weigh 55â95 kg. October 30, 2001 Sloth bears are nevertheless capable of galloping faster than a person can run. A cream-colored V or Y shape usually marks their chests. Sloth bears have two characteristic physical features that have been evolved for feeding on ants and termites: very long, ivory coloured front claws (measuring 7 cm) and a distinct dental arrangement lacking the usual two upper, medial incisors. Their diet includes leaves, honey, flowers, and fruits.
