A study led by Associate Professor Kelton McMahon at University of Rhode Island's Graduate School of Oceanography has found that food webs on tropical reefs are more fragile than we once thought.

Caribbean reef food webs have compressed by up to 70% over the past 7,000 years as fish diets converge and ecosystems become ...

For several years now, one question has held the key to understanding just how much we should worry about the hundreds of tons of DDT that had been dumped off the coast of Los Angeles: How, exactly, ...

The conversion of rainforest into plantations erodes and restructures food webs and fundamentally changes the way these ecosystems function, according to a new study published in Nature. The findings ...
