          Abstract

          When ecologists study organisms with multiphasic life cycles, they must often confront the problem of which phase to scrutinize. In principle, the dynamics and interactions of all stages could play a major role in the regulation of adult populations and species assemblages. In practice, however, the roles of larger and more sedentary phases - being easier to count and manipulate than motile propagules - have been emphasized. Nonetheless, several recent studies on the small, dispersing larval phase of marine invertebrate life cycles reach the conclusion that the spatial distribution and supply of propagules can control the distribution and abundance of populations of benthic adults. To some, the present emphasis on planktonic propagules amounts to a resurrection of ideas developed during a long and rich history of larval biology. To others, studies of demographic and ecological connections between larval and adult populations represent a substantial revision of ecological paradigms. Copyright © 1992.
