Start year: 2003

Summary: Settlement and early establishment (recruitment) are major determinants of population viability of marine organisms, and can vary greatly among oceans and latitudes. We will compare the recruitment dynamics of populations of reef fishes across their range, including at range boundaries where populations may be more vulnerable to environmental impact. We will test the hypothesis that a combination of highly erratic settlement, poor physiological condition of incoming larvae, and poor recruit growth and survivorship will occur at range boundaries. Outcomes of the study will help in prediction of the viability of fish populations which will improve their management and protection.''
