Native amphibian larvae exhibit higher upper thermal limits but lower performance than their introduced predator Gambusia affinis

Information on the thermal limits and physiology of ectothermic amphibians is crucial to our understanding of their ecology in the natural environment, particularly with predicted global changes in climate. We documented the thermal limits of larvae of three amphibian species native to Hong Kong, and their introduced, invasive predator, the mosquitofish (Gambusia affinis). We then used larvae of the brown tree frog Polypedates megacephalus as a...
