Impact of coral predators on tropical reefs
The role of corallivores in reef trophodynamics is more complex than appreciated previously, and there is a growing body of evidence to support that even limited removal of tissue or skeletal structures has growth and/or fit- ness consequences for a scleractinian coral colony.
Selective predation by parrotfishes on the reef coral Porites astreoides
Comparison of C:N ratios among possible dietary components suggests that macroborer consumption could potentially provide nutritional benefits to mainly herbivorous parrotfishes, and provides a novel explanation for selective coral predation by parrotFishes.
Crawling to Collapse: Ecologically Unsound Ornamental Invertebrate Fisheries
The number of grazers now exceeds, by two-fold, the number of specimens collected for curio and ornamental purposes altogether, representing a major categorical shift in the Florida Marine Life Fishery.
Parrotfish abundance and selective corallivory on a Belizean coral reef
A Connection between Colony Biomass and Death in Caribbean Reef-Building Corals
Increased sea-surface temperatures linked to warming climate threaten coral reef ecosystems globally. To better understand how corals and their endosymbiotic dinoflagellates (Symbiodinium spp.)…
Chronic parrotfish grazing impedes coral recovery after bleaching
The results suggest that chronic predation may exacerbate the influence of environmental stressors and, by altering the coral-zooxanthellae symbiosis, such abiotic-biotic interactions may contribute to spatial variation in bleaching processes.
Free-Living Tube Worm Endosymbionts Found at Deep-Sea Vents
These findings support environmental transmission as a means of symbiont acquisition for deep-sea tube worms.

It is determined that PIPA is a spawning area for skipjack, bigeye, and yellowfin (Thunnus albacares) tunas, and both focal taxa spawned inside PIPa in all 3 study years, demonstrating that P IPA is protecting viable tuna spawning habitat.
Temperature and symbiosis affect lesion recovery in experimentally wounded, facultatively symbiotic temperate corals
