Turkey husbandry domestication are confirmed two these regions (Mesoamerica American Southwest), but human-turkey interactions Eastern North (eastern Canada) not fully explored. We apply stable isotope (δ 13 C, δ 15 N) ancient mitoch...

In this paper, we assess the environmental impact of urbanization in three freshwater biotopes, using levels fluctuating asymmetry (FA) 10 meristic morphological traits Marsh Frog (Pelophylax ridibundus (Pallas, 1771)). Two studied biotopes are located boundaries city Plovdiv (one central part, other a suburban residential area), and third is vicinity village Orizare. Our working hypothesis bas...

The role of facilities and associated services for amphibians has recently undergone diversification. Amphibians traditionally used as research models adjust well to captivity and thrive with established husbandry techniques. However, it is now necessary to maintain hundreds of novel amphibian species in captive breeding, conservation research, and biomedical research programs. These diverse sp...

There is increasing evidence that the globe is currently warming, with changes being more pronounced in northern latitudes. Understanding the ecological effects of climatic variability is therefore important. There is recent support for the idea that a large-scale atmospheric phenomenon, the North Atlantic Oscillation (NAO), through its effects on vegetation and regional weather conditions, inf...
