Early waking from hibernation in some amphibian and reptile species from Gümüşhane Province of Turkey

Öz

It is a fact that the amphibians and reptiles respond to unfavourable weather conditions by searching a refuge for living underground during winter. The current literature has shown that some species of reptilian and amphibian may have been active before their known hibernate periods, especially in the lowland areas. In the present study, we reported that the changing weather conditions can cause similar effects on some species of amphibian and reptile that share the same habitats, in a highland area. The early activity of Lacerta media, Bufo bufo and Rana macrocnemis in Gümüşhane Province of Turkey were reported in this study. One of the reasons of the early activity before their known hibernate periods in some amphibian and reptile species may be highly sensitive to the altered temperatures. Effects of global warming on amphibians and reptiles are clearly seen, and they can be active during winter. Our findings bring to mind that L. media, B. bufo and R. macrocnemis can be active as long as air temperatures allow them at the highland areas.

Türkiye’nin Gümüşhane İlindeki Bazı Amfibi ve Sürüngen Türlerinin Kış Uykusundan Erken Uyanması

Öz

Amfibi ve sürüngenlerin kış mevsimi boyunca yaşayabilmek için olumsuz hava koşullarına toprak altında bir sığınak arayarak yanıt verdiği bir gerçektir. Mevcut literatür, bazı sürüngen ve amfibi türlerinin bilinen hibernasyon dönemlerinden önce özellikle de düşük rakımlarda aktif olabildiğini göstermiştir. Bu çalışmada, yüksek rakımda değişen hava koşullarının aynı habitatları paylaşan bazı amfibi ve sürüngen türleri üzerinde benzer etkilere neden olabileceğini rapor ettik. Bu çalışmada Lacerta media, Bufo bufo ve Rana macrocnemis'in erken aktivitesi Türkiye’nin Gümüşhane ilinde rapor edilmiştir. Bazı amfibi ve sürüngen türlerinde bilinen kış uykusu dönemlerinden önceki aktivitelerinin nedenlerinden birisi söz konusu türlerin değişen sıcaklıklara karşı çok hassas olmaları olabilir. Küresel ısınmanın amfibiler ve sürüngenler üzerindeki etkileri açıkça görülmektedir ve kış aylarında aktif olabilirler. Bu durum akla, L. media, B. bufo ve R. macrocnemis'in hava sıcaklıkları izin verdiği sürece aktif olabileceklerini getirmektedir.
