The protandrous marine snail Crepidula fornicata has been a theoretical and empirical model for studies of sex change for many decades. We investigated the social conditions under which sex change occurs in this species by manipulating physical and chemical contact with conspecifics. Male snails were either in physical and chemical contact with females or in chemical contact with, but physically isolated from, females. Males were tested both with living females and with empty, sterilized shells… Expand
The relationship between sex change and reproductive success in a protandric marine gastropod
The results supported expectations showing that male competitive ability for access to the female, time spent by males in the copulatory position, and sibling cannibalism affect reproductive success and influence time to sex change, with less successful males hastening sex change. Expand
Sex Determination, Sexual Development, and Sex Change in Slipper Snails.
The calyptraeid gastropods are presented as a model for the study of the evolution of sex determination in a sequentially hermaphroditic system and the embryonic origins and earliest expression of the germ line are considered. Expand
Fecundity of the invasive marine gastropod Crepidula fornicata near the current northern extreme of its range
Contrary to expectations, size-related fecundities were significantly higher for Norwegian females than for Rhode Island females, with Norwegian females producing larger egg capsules and a greater number of embryos per capsule, but not a greaternumber of egg capsules per brood. Expand
Beyond the sea: Crepidula atrasolea as a spiralian model system.
A developmental transcriptome for C. atrasolea is presented, covering early cleavage through late organogenesis stages, as a useful tool for future studies of gene expression and function, and is provided to the broader developmental community to facilitate widespread use of this system. Expand
Molluscan models: Crepidula fornicata.
Progress towards developingastropod snails in the genus Crepidula as models for evolutionary, developmental, and ecological studies is highlighted, with key insights into the molecular underpinnings of early development. Expand


Effects of conspecific associations on size at sex change in three species of calyptraeid gastropods
The laboratory experiments showed that the response to interactions with conspecifics is generally similar and the differences in size at sex change between the treatments is small and the treatment effect explains more of the variation in size in C. onyx and C. incurva. Expand
Social control of sex change in the shelf limpet, Crepidula norrisiarum : size-specific responses to local group composition
In gastropods the presence of relatively permanent small local mating populations is the critical factor associated with social control of sex change, rather than mode of larval development and dispersal. Expand
Effects of stress on sex change in Crepidula cf. marginalis (Gastropoda: Calyptraeidae)
The results of the desiccation treatment are consistent with theoretical predictions that higher mortality rates should decrease size at sex change and the starvation treatment seems to indicate that animals reduce the allocation to reproduction under extreme stress by entering a non-reproductive transitional stage earlier. Expand
Experimental test of socially mediated sex change in a protandric simultaneous hermaphrodite, the marine shrimp Lysmata wurdemanni (Caridea: Hippolytidae)
The number and complexity of social interactions in large groups may be necessary to stimulate labile sex change in this species and size-ratio induction of sex change by small MPs was suggested but not confirmed. Expand
It is indicated that sex change appears to occur at smaller sizes when large individuals (presumably females) are rare, and the fact that P. ferruginea may exhibit environmentally mediated sex change could influence population management decisions. Expand
Variation in size at sex-change among natural populations of the protandrous hermaphrodite, Crepidula fornicata (Gastropoda, Calyptraeidae)
The data support the conclusions that size at sex-change is not fixed for these hermaphrodites and that individual size, social conditions and population differences all influence variation in relative fitness. Expand
Effects of food availability on sex change in two species of Crepidula (Gastropoda: Calyptraeidae)
The results are consistent with the idea that, as more resources become available, time dedicated to active sexual phases is maximized and the duration of the non-reproductive transitional phase is minimized. Expand
Effects of protandric sex change on radula, pedal morphology, and mobility in Crepidula fecunda (Gastropoda: Calyptraeidae)
A complex interaction was observed between size, mobility, histological changes in the foot, activity, and tooth‐wear of the radula, which have been related to the sessile habit, sex change, and the oviposition process in this species. Expand
Gregariousness and protandry promote reproductive insurance in the invasive gastropod Crepidula fornicata: evidence from assignment of larval paternity
It was pointed out that mating behaviours and patterns of gender allocation varied in concert across sites suggesting that multiple paternities might enhance sex reversal depending on sperm competition intensity. Expand
Sex, Size, and Position: A Test of Models Predicting Size at Sex Change in the Protandrous Gastropod Crepidula fornicata
Three models that predict the size at sex change using estimates of immediate reproductive potential based on individual size and interactions with conspecifics showed that an individual's sex could be predicted as well by its size alone as by the combination of each group member's size. Expand
