December 2013: Rain is proving deadly for young peregrine falcons in Canada's Arctic says scientists from the University of Alberta. The study, recently published in Oecologia, has found that an increase in the frequency of heavy rain brought on by warmer summer temperatures is posing a threat not seen in this species since before pesticides such as DDT were banned from use in Canada in 1970.
A nestbox experiment at the heart of a study co-authored by U of A researcher Alastair Franke and colleagues at the Université du Québec has provided "unequivocal evidence" that gradual changes in Arctic temperature and precipitation are responsible for a long-term decline in reproduction for the peregrine, a top predator in the Arctic.
