Developmental plasticity of cardiorespiratory physiology in response to chronic hypoxia is poorly understood in larval fishes, especially larval airbreathing fishes, which eventually in their development can at least partially ...

The stress response of Oncorhynchus mykiss in high-altitude farms in central Mexico was investigated over two seasons: the cool (9⋅1–13⋅7∘ C) dry winter season, and the warmer (14⋅7–15⋅9∘ C), wetter summer season. Fish ...

Recent global declines and disappearances of amphibian populations have increased the need for information concerning the adversities affecting amphibian populations worldwide. Some of the most alarming cases include the ...
