Monster Seminar JAM - Populational and community consequences of possessing pelagic larvae: musings from a coral reef lagoon
Dr. Peter F. Sale, Dept. of Biolocial Sciences, University of Windsor.
Ecologists who study coral reefs have always known that their organisms possess pelagic larvae, and that larval dispersal and settlement are essential parts of population dynamics. This knowledge has not greatly influenced our general belief, along with most other ecologists, in the existence of communities as objective entities, worthy of study, with their own structure and dynamics. Nor, for the most part, has it affected our understanding of population regulation and species interactions. But perhaps it should have. This seminar explores the consequences of larval dispersal, settlement and recruitment for our understanding of the nature of populations and communities of fish on coral reefs. I review work over the past 25 years that should suggest our ideas about structure and dynamics of these populations and communities have been too complex, inferring capacities to maintain, to repair, or to recover structure that these populations and communities have been too complex, inferring capacities to maintain, to repair, or to recover structure that probably do not exist. Whether reef fish are a model for other kinds of organisms is left for others to decide.
