Fitness effects of spontaneous mutation in a warming world

Jeffry L. Dudycha, Elizabeth S. Davenport, Trenton C. Agrelius & Krista B. Harmon
Spontaneous mutations fuel evolutionary processes and differ in consequence, but the consequences depend on the environment. Biophysical considerations of protein thermostability predict that warm temperatures may systematically increase the deleteriousness of mutation. We sought to test whether mutation reduced fitness more when measured in an environment that reflected climate change projections for temperature. We investigated the effects of spontaneous mutations on life history, size, and fitness in 21 mutation accumulation lines and 12 control lines...
