The importance of planktonic larvae of seafloor-dwelling invertebrates is usually overlooked because they are only temporary members of the plankton. However, these larvae can be crucial components of the planktonic food web considering that the time they spend as plankton is often longer than the life spans of many copepods that remain plankton all their lives. Also, larvae can affect the diversity of planktonic and benthic ecosystems since they take over new habitats and add to adult popula...

Dispersal strategies of the biota on an oceanic seamount: implications for ecology and biogeography.
The Biological Bulletin ; Introduction The study of marine biogeography requires an appreciation of the dispersal capabilities of component species at various stages in their life histories. Recognition of vicariant events can reveal large-scale patterns, but differential dispersal capabilities among species modify those
The distribution of marine invertebrate larvae near vertical surfaces in the Rocky subtidal zone.
Ecology ; INTRODUCTION The question of how far larvae disperse away from their point of release is fundamental to understanding community dynamics in marine benthic systems (Connell 1985, Sebens 1985). Three questions are relevant: (1) how long does a larva remain in the plankton? (2) how much influence, by

Pacific Science ; Abstract: Dispersal distance of planktonic larvae of coral reef organisms is influenced by their ecological characteristics and environmental factors such as current flow and physical structure of reefs. This study reviews the degree and pattern of genetic differentiation in scleractinian corals in

Size, growth, development, and survival of the planktonic larvae of Pomatomus saltatrix (Pisces: Pomatomidae).
Ecology ; INTRODUCTION Size-spectrum theory proposes that the concentration of organisms in pelagic ecosystems decreases as size increases (Sheldon et al. 1972, 1973, Conover 1978, Platt and Denman 1978). Coinciding with this decrease in concentration, mortality rate decreases as organism size increases,
