Perfluorinated compounds (PFCs) are used in a variety of industrial applications. We tested the hypothesis that, in Amur tigers (Panthera tigris altaica), captivity in industrialized areas increases PFC levels, potentially presenting a health risk to these animals. Serum samples were collected from 100 tigers from industrialized or nonindustrialized regions in China with nonpoint sources of PFC...

Background Large carnivores influence ecosystem functions at various scales. Thus, their local extinction is not only a species-specific conservation concern, but also reflects on the overall habitat quality and ecosystem value. Species-habitat relationships at fine scale reflect the individuals' ability to procure resources and negotiate intraspecific competition. Such fine scale habitat choic...

This paper examines the ramifications of late twentieth century water management schemes–especially those initiated by the Republic of Turkey–for the riparians of the Tigris and Euphrates rivers. The Turks’ geographical position, and their ability to construct large water storage systems, has essentially given them command of the headwaters of the Euphrates and, to a lesser degree, the Tigris. ...

In the current study, for first time, Oxynoemacheilus angorae samples were caught from Per?embe Plateau Meandering Streams in Ordu-Turkey (Middle Black Sea Region). field studies, fifteen O. individuals sampled using electrofishing gear. After captured photographed, they placed fish transfer containers and transferred to laboratory. Some metric numbers meristic characteristics of brought labora...

Analysis of skulls and mandibles of the fossil Beringian lion demonstrate that the small lion that inhabited Yakutia (Russia), Alaska (USA), and the Yukon Territory (Canada) is a new subspecies described here as Pu~ltl lcra spelncu z~erc.sl7c-llugirri n. subsp. It differs from the European cave lion P. spelacu (terra typica: Gailenreutl~ Cave, Germany, Late Pleistocene) by its smaller size and ...
