Global warming allows prey to better avoid predators

Posted · Add Comment

Increasing atmospheric and oceanic carbon dioxide (CO2) levels, as well as changing temperatures, is altering the physiology and behaviour of species in many different ways. For one lucky aphid, at least, climate change and global warming is allowing it to better avoid its predator, a wasp parasitoid.

Via measurements of resting metabolic rate (RMR) with the Unisense MicroRespiration system, scientists at VU University Amsterdam, The Netherlands, and Université de Rennes, France, were able to discover that the aphid, at 5 degrees temperature warming, was better able to avoid the wasp.
