Most coral reefs differ from those visited by explorers in the 15th century and described by ecologists in the 195s, and reports of degraded reefs and hypotheses regarding the implications of the changes abound. Tests of these hypotheses require decad . . .

Interactions between scleractinian corals and benthic algae can be an important process structuring reef communities, yet interaction dynamics are not fixed and may be influenced by abiotic factors such as sedimentation, a process often underlying ree . . .

Structural refuges within which prey can escape from predators can be an important limiting resource for the prey. In a manner that resembles the childhood game of musical chairs, many prey species rapidly retreat to shared, unguarded refuges whenever . . .

Field experiments provide rigorous tests of ecological hypotheses but are typically of short duration and use small spatial replicates. We assessed empirically whether the results of experiments testing for density dependence applied at larger spatial . . .
