Project: Mechanisms and Consequences of Fish Biodiversity Loss on Atlantic Coral Reefs Caused by Invasive Pacific Lionfish (BiodiversityLossEffects_lionfish)

This dataset contains results from a field experiment to test for the effect of lionfish and native fish presence on settlement of coral-reef fishes. Native and invasive predators were placed in cages next to small artificial reefs and new recruits settling to reefs were counted and removed daily. Treatments were also rotated daily.  Two rounds of the experiment were run, bracketing the new moon (when settlement rates are highest) in July and August 2014. Sampling took place off the leeward coast of Bonaire, Dutch Caribbean (12°09'13.0"N 68°16'42.8"W) at a 5-meter depth.

These data were utilized in the following publication (Benkwitt 2017)
