Bu araştırma ile Manisa İlindeki memeli faunasının ve bu türler üzerindeki tehditlerin belirlenmesi hedeflenmiştir. Arazi çalışmaları 2018 2019 yıllarında toplamda 45 gün boyunca gerçekleştirilmiştir. Çalışmalar sonucunda 36 farklı karasal iç su türü tespit edilmiştir. Mevcut içinden özellikle büyük etçil olan Çakal (Canis aureus), Kurt lupus), Bozayı (Ursus arctos), Karakulak (Caracal caracal)...
The right third eyelid of an adult female brown bear (Ursus arctos) was swollen and removed. Histopathology revealed a tumor exhibiting proliferation with mild infiltration, consisting of multi-stratified glandular structures of the innermost laminal neoplastic cells and the basaloid neoplastic cells, and with eosinophilic thick basal lamina material around the glandular structures. Both types ...
Mitochondrial DNA analysis of Iranian brown bears (Ursus arctos) reveals new phylogeographic lineage
Abstract Stable isotope analysis of animal tissue samples is increasingly used to study the trophic ecology target species. The isotopic signatures respond type diet, but also environmental conditions their habitat. In case omnivorous, seasonal or opportunistic feeding species, interpretation values more complex, as it largely determined by food selection, either due individual choice because a...
Cave bears (Ursus spelaeus) existed in Europe and western Asia until the end of the last glaciation some 10,000 years ago. To investigate the genetic diversity, population history, and relationship among different cave bear populations, we have determined mitochondrial DNA sequences from 12 cave bears that range in age from about 26,500 to at least 49,000 years and originate from nine caves. Th...
