Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...
