Murre sensitivity to changes in temperature
Hugo Ahlenius, UNEP/GRID-Arendal
Annual rates of population change of individual murre colonies during 12 years after the 1977 climatic regime shift in the North Pacific and during 9 years after the 1989 shift, in relation to changes in sea surface temperatures around the colonies from one decadal regime to the next. Population data are from 32 U. aalge and 21 U. lomvia colonies, encompassing the entire circumpolar region. Ten sites supported both species, so 43 different study areas were represented.
