“…This effect is more likely to occur in the inner edge, where vermetids are exposed to air during low tide for a longer period than the outer edge, and recruits may not benefit from wave splashing, which occurs more frequently on the outer edge of the reef under calm sea conditions. Russell and Phillips (2009) support our hypothesis, reporting that embryos of rocky intertidal species may be at risk of high mortality particularly during summer when elevated ultraviolet (UV) radiation and high temperatures coincide with low tide cycles, which are conditions that presumably have occurred at the inner edge in this study. In addition, research by Przeslawski (2005) found that solar radiation, desiccation time and oxygen deficiency affect the mortality and the developmental rate of early stage intertidal gastropods.…”

In the Mediterranean, the gastropod Dendropoma cristatum (sin. D. petraeum (Monterosato, 1884)) is the primary builder of the vermetid reef, an intertidal bioconstruction of exceptional ecological importance. Despite awareness of the need for conservation of this key species, the biology of D. cristatum remains poorly understood. The recruitment of D. cristatum deserves particular attention because the absence of a planktonic larval stage limits its dispersal ability. We examined the temporal pattern of recruitment during the breeding season of D. cristatum from June to September in 2013. Specifically, we compared the two portions of the vermetid reef (i.e. the inner edge and the outer edge) at localities with different exposures to wave motion. The number of recruits peaked in July, when it was significantly higher in the outer than in the inner edge. No differences emerged between localities with different wave exposures; however, the width of the reef was significantly related to the exposure index. Although there are still several gaps in our knowledge of the recruitment dynamics of D. cristatum, this study contributes to characterising recruitment rate variation at small spatial and temporal scales.

“…All studies were conducted in the laboratory although four studies included complementary field experiments. Of these four studies, three found similar overall effects of stressors between field and laboratory experiments (Preston, ; Russell & Phillips, ,b). However, Przeslawski () found that desiccation in the field caused significant mortality to embryos of two gastropod species, while desiccation showed no effect on these species in the laboratory.…”

Marine organisms are simultaneously exposed to anthropogenic stressors with likely interactive effects, including synergisms in which the combined effects of multiple stressors are greater than the sum of individual effects. Early life stages of marine organisms are potentially vulnerable to the stressors associated with global change, but identifying general patterns across studies, species and response variables is challenging. This review represents the first meta-analysis of multistressor studies to target early marine life stages (embryo to larvae), particularly between temperature, salinity and pH as these are the best studied. Knowledge gaps in research on multiple abiotic stressors and early life stages are also identified. The meta-analysis yielded several key results: (1) Synergistic interactions (65% of individual tests) are more common than additive (17%) or antagonistic (17%) interactions. (2) Larvae are generally more vulnerable than embryos to thermal and pH stress. (3) Survival is more likely than sublethal responses to be affected by thermal, salinity and pH stress. (4) Interaction types vary among stressors, ontogenetic stages and biological responses, but they are more consistent among phyla. (5) Ocean acidification is a greater stressor for calcifying than noncalcifying larvae. Despite being more ecologically realistic than single-factor studies, multifactorial studies may still oversimplify complex systems, and so meta-analyses of the data from them must be cautiously interpreted with regard to extrapolation to field conditions. Nonetheless, our results identify taxa with early life stages that may be particularly vulnerable (e.g. molluscs, echinoderms) or robust (e.g. arthropods, cnidarians) to abiotic stress. We provide a list of recommendations for future multiple stressor studies, particularly those focussed on early marine life stages.

“…Lesser et al (1990) and Hoffman et al (2003) have shown a dramatic interaction between UVR and temperature stress that can alter organismal responses to other abiotic environment. Studies by Przeslawski (2004), Przeslawski et al (2005) and Russell and Phillips (2009) have highlighted the dramatic underestimation the effect of multiple stressors has on development of marine invertebrate embryos including osmotic, temperature and UVR stress.…”

iv EXPOSURE TO ULTRAVIOLET RADIATION CAUSES PROTEOMIC CHANGES IN EMBRYOS OF THE PURPLE SEA URCHIN, STRONGYLOCENTROTUS PURPURATUS Joseph Paul CampanaleThe amount of solar ultraviolet radiation (UVR, 290-400 nm) reaching Earth's surface is increasing due to ozone depletion and global climate change. Embryos of the purple sea urchin, Strongylocentrotus purpuratus, provide an ideal system for examining how UVR affects developing marine organisms and cells in general. To model the protein-mediated cell cycle response to UV-irradiation, six batches of S. purpuratus embryos were exposed to UVR, monitored for delays in the first mitotic division and examined for global proteomic changes. Embryos from each batch were exposed to or protected from artificial UVR for 25 or 60 min. Embryos treated with UVR for 60 min cleaved an average of 23.24 min (±1.92 s.e.m) later than the UVprotected embryos. Protein expression of UV-protected and UV-treated embryos was examined at 30 and 90 min post-fertilization using two dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (2D SDS-PAGE) and mass spectrometry (MS). Proteins were isoelectrically focused (pH 4-7) and separated by molecular weight using SDS-PAGE. At least 1,306 protein spots were detected in all gels. A total of 171 protein spots (13% of the detected proteome) migrated differently in UVtreated embryos at 30 min post-fertilization and 187 spots (14%) at 90 min postfertilization (2-way ANOVA, P= 0.03, n=6). Our results identify the differential migration of proteins from multiple cellular pathways and are the first to indicate that the mechanisms involved in the protein mediated UV-induced developmental delay are integrated among pathways for cellular stress, protein turnover and translation, signal transduction, general metabolism and involve the cytoskeleton.
