Abstract

Experimental results testing Janzen-Connell hypothesis in brooding corals: whether juvenile corals experienced distance-dependent mortality near adult conspecifics.

Experiment testing Janzen-Connell hypothesis in brooding corals - whether juvenile corals experienced distance-dependent mortality near adult conspecifics.

To determine the spatial distribution of P. damicornis and S. hystrix at smaller scales, we conducted 2 m radius circular surveys around focal P. damicornis and S. hystrix colonies that i) were the largest colony of that species within 4 m (to reduce the effects of conspecifics), and ii) occurred where >75% of the substrate within 2 m was suitable habitat for P. damicornis and S. hystrix, again to equalize the likelihood of colonies occurring everywhere in the survey.
