Building bridges across subdisciplines in marine ecology

Abstract

Ecology has evolved many subdisciplines whose members do not necessarily communicate regularly through attending the same meetings or reading and publishing in the same journals. As a result, explanations of ecological processes are often limited to a single factor, process, or group of organisms, and this limited approach may fail to provide the best understanding of how communities and ecosystems are assembled and function. Specifically, there is a need to bring together information on the interplay of top-down and bottom-up influences on complete communities consisting of both macroorganisms and microorganisms. A number of examples from the recent literature illustrate the problems encountered in achieving this goal. These include declining fish populations, estuarine eutrophication, the complex origin of a toxic dinoflagellate bloom, and the interactions of microorganisms and macrooorganisms in marine planktonic food webs.
