The increasing demand for resources to meet the needs of our society has transformed environment and increased likelihood human-wildlife interactions. Romania highest density brown bears in Europe, with more than 7000 individuals populating Carpathian Mountains neighboring areas. large bear population inhabits ever-increasing human-dominated landscapes, which frequently results conflict humans....
a new reservoir host of trichinella was identified as: herpestes auropunctatus, (mangoose) in province of khuzestan, south west of iran. wild swine, brown bear jackal and wild cat have been reported as natural host for trichinella so far. the larvae obtained from the mongoose was infective for rat and white mouse, but the latter was more sensitive comparatively (this study was carried out in th...
Hailer et al. (1) sequenced 14 independent nuclear loci across the genomes of polar (Ursus maritimus), brown (U. arctos), and American black bears (U. americanus). The Bayesian multilocus coalescent approach showed one species tree in which polar bears split from brown bears before the diversification of brown bear lineages. The divergence of polar bears was estimated to have occurred 603 thous...
protected areas are major tourism assets for a nation, particularly for developing countries providing sustainable benefit to the local community while funding for the maintenance and rehabilitation of the protected areas themselves. valley of flowers national park is naturally meant for the conservation and study of western himalayan flora. it became national park in 1982 and after that livest...
this study was conducted to investigate theallometric growth pattern and sexual dimorphism in the skull of both sexes ofiranian brown bear (ursus arctos) in thealborz mountains using geometric morphometric and traditional morphometric techniques. morphometric parameters were obtained from 2d pictures of skulls using the software imagej and allometric growth pattern was calculated as a power fun...
The polar bear has become the flagship species in the climate-change discussion. However, little is known about how past climate impacted its evolution and persistence, given an extremely poor fossil record. Although it is undisputed from analyses of mitochondrial (mt) DNA that polar bears constitute a lineage within the genetic diversity of brown bears, timing estimates of their divergence hav...
Delineating protected areas for sensitive species is a growing challenge as changing climate alters the geographic pattern of habitats as well as human responses to those shifts. When human impacts are expected within projected ranges of threatened species, there is often demand to demarcate the minimum habitat required to ensure the species' persistence. Because diminished or wide-ranging popu...
