Deeper understanding of species roles in ecosystems

A species' traits define the role it plays in the ecosystem in which it lives—this is the conclusion of a study carried out by researchers at Linköping University, Sweden. New methods can make it easier to predict the ...

Key biological mechanism is disrupted by ocean acidification

A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide added to the atmosphere ...

Study shows how a tiny sea animal feeds itself and the ocean

Dime-sized ocean organisms thought to graze on any particles in their path are actually picky eaters, and their food-filtering process may be vital to how organic materials are distributed from surface waters to the ocean ...

Climate shifts shorten marine food chain off California

Environmental disturbances such as El Niño shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant ...

Old fish few and far between under fishing pressure

Like old-growth trees in a forest, old fish in the ocean play important roles in the diversity and stability of marine ecosystems. Critically, the longer a fish is allowed to live, the more likely it is to successfully reproduce ...
