The interactive influence of temperature and salinity on larval and juvenile growth in the gastropod Crepidula fornicata (L.)

Estimates of planktonic larval mortality using the marine gastropods Crepidula fornicata and C. plana

Estimates of planktonic larval mortality rates have varied widely over the past 50 yr, from about 0% d–1 to 80% min–1. Convincing estimates from field sampling programs have proved difficult to obtain. This study considered the impact of predation pressure on larval growth rates for 2 species of the gastropod genus Crepidula whose larvae grow linearly over time. We reasoned that slow-growing la...

Relationship between larval and juvenile growth rates in two marine gastropods, <Emphasis Type="Italic">Crepidula plana</Emphasis> and <Emphasis Type="Italic">C. fornicata</Emphasis>

Previous studies on various marine mollusc species have shown that both larval and juvenile growth rates are substantially heritable, but few workers have examined the extent to which larval and juvenile growth rates covary. We examined the relationship between larval and juvenile growth rates in seven laboratory experiments conducted between 1986 and 1993, using the prosobranch gastropods Crep...

Relationships between larval nutritional experience, larval growth rates, juvenile growth rates, and juvenile feeding rates in the prosobranch gastropod Crepidula fornicata

Planktonic larvae experiencing short periods of starvation or reduced food supply often grow and develop more slowly, have poor survival, fail to metamorphose, metamorphose at smaller sizes, or grow slowly as juveniles. In this study, we examined the impact of short periods of food limitation at various stages of larval development on larval and juvenile growth in Crepidula fornicata. In additi...

The importance of larval supply, larval habitat selection and post-settlement mortality in determining intertidal adult abundance of the invasive gastropod Crepidula fornicata

Seasonal Variations in Maternal Provisioning of Crepidula fornicata (Gastropoda): Fatty Acid Composition of Females, Embryos and Larvae

Recruitment success of marine invertebrate populations not only depends on the number of recruits but also on their quality which affects their survival. In species characterized by a mixed development (encapsulated embryonic development and release of planktotrophic larvae), the offspring quality depends on both maternal provisioning and larval feeding. Here, we investigated potential changes ...
