Brief synopsis of current research:
We study the nature and properties of ecological complexity by detail examination of invertebrate communities inhabititing miniature coastal rock pools in Jamaica. Various questions currently investigated include (a) dependency of biodiversity assessments on the scale of the habitat, its variability, and species composition; (b) spatial habitat hierarchy and its effects of species variation, abundance structure, community stability, and meta-community dynamics and (c) experimental assessment of habitat heterogeneity. To answer some of these questions, we also use coral reef fish communities in the same area.
