Body mass index does not decline during winter for the sedentary marine gastropod Crepidula fornicata
<p><span>Extremes in environmental conditions can limit growth and reproduction of animals. Sedentary marine animals are particularly susceptible to winter food limitation since they cannot relocate to more favorable conditions. Winter conditions have been linked to tissue mass declines as high as 70% in several temperate-zone suspension-feeding bivalve species; however, no comparable studies have been conducted on intertidal gastropods. Here, we investigate whether the suspension-feeding intertidal marine gastropod Crepidula fornicata also loses substantial tissue mass during the winter. We calculated body mass index (BMI; mg dry weight/(cm shell length)3) for individuals collected at different times of year for seven years from 2009-2019 and determined whether winter or environmental conditions influenced BMI. Remarkably, C. fornicata body mass did not decline during winter months; indeed, a relatively poorer body condition was associated with higher seawater temperature, higher air temperature and higher chlorophyll concentration. In a laboratory experiment, we found that C. fornicata that were starved for three weeks at 6 °C (local winter seawater temperature) showed no detectable declines in BMI compared to field collected individuals. Future studies should document energy budgets of sedentary marine animals at low winter seawater temperatures, and the impact of short-term elevated temperatures on those energy budgets.</span></p>

Data from: Contrasting patterns of genome-wide polymorphism in the native and invasive range of the marine mollusk Crepidula fornicata
Selection processes are believed to be an important evolutionary driver behind the successful establishment of non-indigenous species, however evidence is still scarce. Genome-scans have often identified loci with atypical patterns of genetic differentiation (i.e. outliers) indicative of selection processes. Using microsatellite- and AFLP-based genome-scans, we looked for evidence of post-introduction selection in the mollusk Crepidula fornicata, native from the northwestern Atlantic and introduced in the northeastern Atlantic and northeastern Pacific during the 19th and 20th centuries. We examined 683 individuals from 7 native and 15 introduced populations spanning the latitudinal introduction and native ranges of the species. Our results showed the high genetic diversity in all populations with little genetic structure between the two ranges, a pattern typical of marine invaders. Analyzing 344 loci, no outliers were detected between introduced and native populations or within introduced populations. The genomic sampling may have been insufficient to reveal selection especially if it acts on traits determined by a few genes. Eight outliers were however identified within the native range, underlining a genetic singularity congruent with a well-known biogeographic break along the Florida. Our results call into question the relevance of AFLP genome-scans in detecting adaptation on the time-scale of biological invasions: genome-scans often reveal long-term adaptation involving numerous genes throughout the genome but seem less effective in detecting recent adaptation from pre-existing variation on polygenic traits. This study advocates other methods to detect selection effects during biological invasions – on phenotypic traits, although genome-scans may remain useful for elucidating introduction histories.
Data from: The size advantage model of sex allocation in the protandrous sex-changer Crepidula fornicata: role of the mating system, sperm storage, and male mobility
Sequential hermaphroditism is adaptive when the reproductive value of an individual varies with size or age, and this relationship differs between males and females. In this case, theory shows that the lifetime reproductive output of an individual is increased by changing sex (a hypothesis referred to as the size-advantage model). Sex-linked differences in size-fitness curves can stem from differential costs of reproduction, the mating system, and differences in growth and mortality between sexes. Detailed empirical data is required to disentangle the relative roles of each of these factors within the theory. Quantitative data are also needed to explore the role of sperm storage, which has not yet been considered with sequential hermaphrodites. Using experimental rearing and paternity assignment, we report relationships between size and reproductive success of Crepidula fornicata, a protandrous (male-first) gastropod. Male reproductive success increased with size due to the polygamous system and stacking behavior of the species, but females nonetheless had greater reproductive success than males of the same size, in agreement with the size-advantage theory. Sperm storage appeared to be a critical determinant of success for both sexes, and modeling the effect of sperm storage showed that it could potentially accelerate sex change in protandrous species.
