Many seabirds in the Northern Hemisphere are struggling to breed -- and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.
The international team of scientists -- led by William Sydeman at the Farallon Institute in California -- discovered that reproductive success decreased in the past half century for fish-eating seabirds north of the equator. The Northern Hemisphere has suffered greater impacts from human-caused climate change and other human activities, like overfishing.
