Parasites may get nastier with climate swings: study - Yahoo! News
In one experiment, frogs kept at a temperature of 25 degrees Celsius (77F) for four weeks suffered far more infections when they were shifted to incubators at 15C (59F) and exposed to the fungus than frogs already used to living at 15C.
"If you shift the temperature a frog is more susceptible to infection than a frog that is already adapted to that temperature," Raffel said.
In another test, frogs that were exposed to predictable daily temperature variations between 15 and 25 Celsius, typical of shifts from night to day, were much better at resisting the fungus.
