“…Therefore, it is not surprising that variation among females is common (e.g. echinoids: Lessios, 1987; Berger & Jelinski, 2008; bivales: Phillips, 2007; gastropods: Collin, 2010). Lessios (1987) found significant differences in egg size between females in each of 13 species of tropical echinoids that were spawned immediately after collection.…”

Intraspecific variation in egg size and hatching size, and the genetic and environmental trade-offs that contribute to variation, are the basis of the evolution of life histories. The present study examined both univariate and multivariate temperature-mediated plasticity of life-history traits, as well as temperature-mediated trade-offs in egg size and clutch size, in two planktotrophic species of marine slipper limpets, Crepidula. Previous work with two species of Crepidula with large eggs and lecithotrophic development has shown a significant effect of temperature on egg size and hatching size. To further examine the effect of temperature on egg size in Crepidula, the effects of temperature on egg size and hatching size, as well as the possible trade-offs with other the life-history features, were examined for two planktotrophic species: Crepidula incurva and Crepidula cf. marginalis. Fieldcollected juveniles were raised at 23 or 28°C and egg size, hatching size, capsules/brood, eggs/capsule, time to hatch, interbrood interval, and final body weight were recorded. Consistent with results for the lecithotrophic Crepidula, egg size and hatching size decreased with temperature in the planktotrophic species. The affects of maternal identity and individual brood account for more than half of the intraspecific variation in egg size and hatching size. Temperature also showed a significant effect on reproductive rate, with time to hatch and interbrood interval both decreasing with increasing temperature. However, temperature had contrasting effects on the number of offspring. Crepidula cf. marginalis has significantly more eggs/capsule and therefore more eggs per brood at 28°C compared to 23°C, although capsules/brood did not vary with temperature. Crepidula incurva, on the other hand, produced significantly more capsules/brood and more eggs per brood at the lower temperature, whereas the number of eggs/capsule did not vary with temperature. The phenotypic variance-covariance matrix of life-history variables showed a greater response to temperature in C. incurva than in C. cf. marginalis, and temperature induced trade-offs between offspring size and number differ between the species. These differences suggest that temperature changes as a result of seasonal upwelling along the coast of Panama will effect the reproduction and evolution of life histories of these two co-occurring species differently.

“…Schick and Urban (2000) noted that, despite a terrestrial bias, the techniques of landscape ecology are germane to marine applications, and demonstrated this in an analysis of the spatial components of bowhead whale (Balaena mysticetus) distributions. Berger and Jelinski (2008) examined spatial patterns in maternal investment in red sea urchins (Strongylocentrotus franciscanus) along a near-shore marine terrestrial gradient. Stable isotope data show a winter shift in increasing amounts of refractory terrestrial detritus to mysid (order Mysida) diets in coastal British Columbia, Canada (Mulkins et al 2002).…”

“…A New Zealand fjord with high input and long residence time of forest litter has strong incorporation of terrestrial carbon into the marine food web, particularly by subsurface deposit feeders (sea urchin and polychaetes) (McLeod and Wing, 2009). Similarly, a sea urchin population in a sound off British Columbia showed no variation in 13 C along the sound, suggesting that terrestrial organic matter was relatively unimportant (Berger and Jelinski, 2008). Other members of the fjord benthos were supported by marine carbon sources, despite the heavy input of leaf litter from rain forests into the fjord.…”
