Energetic constraints, size gradients, and size limits in benthic marine invertebrates.
Populations of marine benthic organisms occupy habitats with a range of physical and biological characteristics. In the intertidal zone, energetic costs increase with temperature and aerial exposure, and prey intake increases with immersion time, generating size gradients with small individuals often found at upper limits of distribution. Wave action can have similar effects, limiting feeding t...
متن کاملEnergetic Constraints, Size Gradients, and Size Limits in Benthic Marine Invertebrates1
SYNOPSIS. Populations of marine benthic organisms occupy habitats with a range of physical and biological characteristics. In the intertidal zone, energetic costs increase with temperature and aerial exposure, and prey intake increases with immersion time, generating size gradients with small individuals often found at upper limits of distribution. Wave action can have similar effects, limiting...
متن کاملSize and Performance of Juvenile Marine Invertebrates: Potential Contrasts Between Intertidal and Subtidal Benthic Habitats
SYNOPSIS. Newly settled or hatched juveniles of marine benthic invertebrates generally experience very high mortality. Juvenile mortality can profoundly affect adult populations, but little is known about how individual variation in juvenile quality affects performance. Several recent studies have demonstrated that differences in size, larval nutrient stores, or larval feeding history can stron...
متن کاملThe evolutionary ecology of offspring size in marine invertebrates.
Intraspecific variation in offspring size is of fundamental ecological and evolutionary importance. The level of provisioning an organism receives from its mother can have far reaching consequences for subsequent survival and performance. In marine systems, the traditional focus was on the remarkable variation in offspring size among species but there is increasing focus on variation in offspri...
متن کاملReproductive Strategies of Marine Benthic Invertebrates : A Settlement - Timing Hypothesis
Evidence for nudibranch molluscs is presented which shows a clear relationship between egg-size and developmental mode (planktotrophic, lecithotrophic and direct development), egg-size and development time, and thereby larval strategy and development time. Egg-to-juvenile periods differ significantly according to strategy, with lecithotrophic pelagic development being the briefest, and planktot...
