  • Audubon Nature Institute 2016
    CONSERVATION Celebrating Audubon Nature Institute Each day, our partners here at the Wonders home and around the globe of Nature work with us on fulfilling our 2016 shared goals. All eight objectives of the Audubon Nature Institute mission have conservation at their core, particularly our pledges to preserve native Louisiana habitats and to enhance the care and survival of wildlife through research and conservation. That’s why we wanted to show you the scope of Audubon’s conservation commitment through this report. These projects are top of mind for us every day, and we work on them together—donors, members, guests, employees, and peer organizations around the world. From the smallest act of recycling a piece of paper to multi-national coalitions saving species oceans away, we know we must keep pushing forward. The stakes are high, and together, we are making progress.

Wayne5* Protection of populations comprising admixed genomes is a challenge under the Endangered Species Act (ESA), which is regarded as the most powerful species protection legislation ever passed in the United States but lacks specific provisions for hybrids. The eastern wolf is a newly recognized wolf-like species that is highly admixed and inhabits the Great Lakes and eastern United States, a region previously thought to be included in the geographic Downloaded from range of only the gray wolf. The U.S. Fish and Wildlife Service has argued that the presence of the eastern wolf, rather than the gray wolf, in this area is grounds for removing ESA protection (delisting) from the gray wolf across its geographic range. In contrast, the red wolf from the southeastern United States was one of the first species pro- tected under the ESA and was protected despite admixture with coyotes. We use whole-genome sequence data to demonstrate a lack of unique ancestry in eastern and red wolves that would not be expected if they represented long divergent North American lineages.

Recent genetic studies have revealed the existence of three lineages of wolves in the Indian sub-continent. Of these, the Himalayan wolf, Canis lupus chanco, has been reported to be the most ancient lineage histori- cally distributed within the Nepal Himalaya. These wolves residing in the Trans-Himalayan region have been suggested to be smaller and very different from the European wolf.

In the South, the tropical green will be at its height with very special encounters with the Asiatic Elephant and bird life of the region. The wildlife of Central India one of India and the world’s most densely forested regions, attracts a large number of wildlife enthusiasts, researchers, and ornithologists from different parts of the world. Wildlife in Central India includes the Royal Bengaltiger, the asiatic leopard, the caracal or desert cat, langur and rhesus monkey, the chital or spotted deer, nilgai or the blue bull, the sambharstag, and the Gaur or Indian bison. Also included are adiverse species of birdlife. These wildlife sanctuaries in the heart of India’s Kipling country offer visitorsan opportunity of discovering the rich and varied flora and fauna of India’s middle animal kingdom. The famous albino or white tigers also came from Central India. Bandhavgarh National Park located in Madhya Pradesh is one of the best and most picturesque tiger reserves of India. Set in the picturesque surroundings of the eastern edge of the Satpura and Vindhya hill ranges, Bandhavgarh National Park is famous for its Tiger population.

One of the canids was a sub-adult captive maned wolf Chrysocyon brachyurus (Illiger, 1815), revealing skull damaged by canine tooth perforation and several bruises along the body. Examination of the wounds and the killing site provided reasonable details on how the attack was conducted. The mountain lion grabbed the maned wolf from behind with both forepaws, and killed it with a bite at the nape of the neck and at the back of the skull.
