Study Shows Change in Oceanic Food Web

摘要

A study on the endangered Hawaiian Petrel by scientists from Michigan State University, the Smithsonian Institution and eight other organizations has found a shift in bird foraging habits that is likely linked to industrial fishing in the Pacific. The research looked at the chemistry of feathers and bones of modern Hawaiian Petrels, as well as bones from subfossils up to 4,000 years old, to determine where on the food chain and in the Pacific Ocean the birds have been foraging throughout the centuries.
