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.

A baby coral, freshly settled on a reef surface, faces terrible odds. Predators graze over it. Sediment smothers it. And as ...

A new study links grazing halo patterns in coral reefs, as well as those in other patchy habitats, to the spatial patterns of the shelter habitat itself. The researchers found that grazing halos are ...

Living by the sea in the tropics means being exposed to some of nature's most powerful forces. Hurricanes can bring storm ...

A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became ...

Coral reefs make up a tenth of one percent of the ocean’s surface area but support up to a third of multicellular ocean species. The reefs provide valuable shelter from predators and ocean currents ...

Lancaster University marine biologist Sally Keith and her colleagues were looking into how the behaviour of butterflyfish might vary geographically — but then a mass coral bleaching event hit, and the ...

Grazing halos at Heron Island, Australia, are distinct where coral are clustered (outlined with a white box) but merge where coral are dispersed (outlined with a black box). In coral reefs throughout ...
