▪ Abstract Declines and losses of amphibian populations are a global problem with complex
local causes. These may include ultraviolet radiation, predation, habitat modification …

As potential to adapt to environmental stress can be essential for population persistence,
knowledge on the genetic architecture of local adaptation is important for conservation …

Water pH is an important factor affecting the general water quality as well as quality traits in
fishes, and the magnitude of the effect varies among species. The massive and negative …
