Abstract. When juveniles must tolerate harsh environments early in life, the disproportionate success of certain phenotypes across multiple early life stages will dramatically influence adult community composition and dynamics. In many species, large offspring have a higher tolerance for stressful environments than do smaller conspecifics (parental effects). However, we have a poor understanding of whether the benefits of increased parental investment carry over after juveniles escape harsh environments or progress to later life stages (latent effects). To investigate whether parental effects and latent effects interactively influence offspring success, we determined the degree to which latent effects of harsh abiotic conditions are mediated by offspring size in two stony coral species. Larvae of both species were sorted by size class and exposed to relatively high-temperature or low-salinity conditions. Survivorship was quantified for six days in these stressful environments, after which surviving larvae were placed in ambient conditions and evaluated for their ability to settle and metamorphose. We subsequently assessed long-term post-settlement survival of one species in its natural environment. Following existing theory, we expected that, within and between species, larger offspring would have a higher tolerance for harsh environmental conditions than smaller offspring. We found that large size did enhance offspring performance in each species. However, large offspring size within a species did not reduce the proportional, negative latent effects of harsh larval environments. Furthermore, the coral species that produces larger offspring was more, not less, prone to negative latent effects. We conclude that, within species, large offspring size does not increase resistance to latent effects. Comparing between species, we conclude that larger offspring size does not inherently confer greater robustness, and we instead propose that other life history characteristics such as larval duration better predict the tolerance of offspring to harsh and variable abiotic conditions. Additionally, when considering how stressful environments influence offspring performance, studies that only evaluate direct effects may miss crucial downstream (latent) effects on juveniles that have significant consequences for long-term population dynamics.

“…Latent effects have been observed in this species in response to larval nutritional stress (Pechenik et al, 1996a,b), but no latent effects were found from larval exposure to low salinity stress (Diederich et al, 2011). In the latter study, Diederich et al (2011) reared the postmetamorphic juveniles in stress-free, control salinity conditions.…”

“…Previous research has demonstrated that C. fornicata juveniles can separately tolerate salinities as low as 15 and temperatures as high as 32°C (Pechenik and Eyster, 1989), while larvae can tolerate salinity at least as low as 15 (Diederich et al, 2011) and temperatures up to at least 30°C (Lucas and Costlow, 1979;Pechenik and Lima, 1984). A number of studies have documented that C. fornicata larvae grow faster at higher temperatures (Klinzing and Pechenik, 2000;Lucas and Costlow, 1979;Pechenik, 1984;Pechenik and Heyman, 1987;Pechenik and Lima, 1984) but no studies have investigated the interactive effects of temperature and salinity on the growth of C. fornicata larvae and juveniles.…”

“…Transport of the free-swimming larvae with ballast water may also occur during the relatively long pelagic larval phase of *2-4 weeks (Pechenik 1980(Pechenik , 1984. The larvae, juveniles, and adults are relatively euryhaline and eurythermal (Pechenik and Lima 1984;Pechenik and Eyster 1989;Rigal 2009;Diederich et al 2011;Schubert 2011), hence increasing the chances of survival when exposed to the changeable environmental conditions between the donor region, the transport vector, and release into the new environment. This also enables C. fornicata to thrive in a variety of environmental conditions and habitat types, predominantly shallow estuaries and bays (Loomis and Van Nieuwenhuyze 1985;Blanchard 1997), but also relatively deep high-energy environments .…”

The distribution of the invasive non-native gastropod Crepidula fornicata in the Milford Haven Waterway, its northernmost population along the west coast of Britain

The invasive non-native gastropod Crepidula fornicata is well established in the Milford Haven Waterway (MHW) in south-west Wales, UK, since its first introduction to this ria in 1953. Whilst it reaches high densities within the MHW and has extended its range to the south of this ria, there has been very little northward expansion. Here, we report findings of a series of intertidal and subtidal surveys in 2009 and 2010 where we monitored the population density and the vertical distribution of C. fornicata at its northern range limit in Wales (the MHW). We also characterised the composition of the surface substrata of the seabed in the MHW to provide some insight into how the availability of certain settlement substrata may limit its distribution along the west coast of Britain. We found locally very dense aggregations (maximum 2748 ± 3859 individuals m -2 , mean ± SD) in the shallow subtidal and low intertidal of the MHW. Subtidally, highest densities were found in areas of high gravel content (grain sizes *16-256 mm), suggesting that the availability of this substrata type is beneficial for its establishment at a site. In the intertidal, on the other hand, high gravel content was indicative of low C. fornicata abundance, possibly because gravelly shores are an indicator of very exposed conditions that, at least in the intertidal, may result in high levels of early post-settlement mortality and low recruitment. C. fornicata was absent from the entrance of the MHW, possibly due to the lack of suitable settlement substrata. The presence of substantial populations in the MHW suggests that C. fornicata's population growth and potential expansion in Welsh coastal waters is not fully limited by prevailing environmental conditions in the region, but that other processes may affect its local distribution.
