Temperature, but not pH, compromises sea urchin fertilization and early development under near-future climate change scenarios
The thermotolerance and pH resilience of fertilization and embryogenesis within predicted climate change scenarios are confirmed, with negative effects at upper limits of ocean warming. Expand

The results show that projected near-future climate change will have deleterious effects on development with differences in vulnerability in the two species, and Haliotis development was most sensitive with no interaction between stressors. Expand
Impact of Ocean Warming and Ocean Acidification on Larval Development and Calcification in the Sea Urchin Tripneustes gratilla
This study of the effects of ocean warming and CO2 driven acidification on development and calcification of marine invertebrate larvae reared in experimental conditions from the outset of development shows the positive and negative effects of these stressors. Expand
Fertilization in a suite of coastal marine invertebrates from SE Australia is robust to near-future ocean warming and acidification
Climate change driven ocean acidification and hypercapnia may have a negative impact on fertilization in marine organisms because of the narcotic effect these stressors exert on sperm. In contrast,Expand
Sea urchin fertilization in a warm, acidified and high pCO2 ocean across a range of sperm densities.
The results indicate that sea urchin fertilization is robust to climate change stressors, however, developmental stages may be vulnerable to ocean change. Expand
Experimental manipulation of shade, silt, nutrients and salinity on the temperate reef sponge Cymbastela concentrica
This work makes a significant contribution to the understanding of the mechanisms that underpin the changes in patterns observed when sponges are exposed to physical factors associated with a sewage plume. Expand
Genetic evidence for contrasting patterns of dispersal in solitary and colonial ascidians
It is estimated (via Wright's “island model”) that gene flow within this set of local populations is 125 effective migrants per generation, which is very similar to estimates obtained for other broadcast-spawning taxa in this region and implies that local populations are effectively closed to immigration. Expand
Differences in soft-sediment macrobenthic assemblages invaded by Caulerpa taxifolia compared to uninvaded habitats
It is suggested that infauna may be particularly vulnerable to invasion because of changes to sediment chemistry, and differences in redox potential (and associated chemical changes) may explain patterns in abundance of infauna among habitats. Expand
Epibiosis of Marine Algae and Benthic Invertebrates: Natural Products Chemistry and Other Mechanisms Inhibiting Settlement and Overgrowth
Chemical and physical mechanisms by which non-motile marine invertebrates and marine algae inhibit the fouling of their surfaces are reviewed and ecological and evolutionary considerations are placed. Expand
Synergistic effects associated with climate change and the development of rocky shore molluscs
Exposure of encapsulated embryos of three common rocky shore gastropods to simultaneous combinations of ecologically realistic levels of ultraviolet radiation, water temperature stress and salinity stress detected synergistic effects with increases in mortality and retardation in development associated with the most physiologically stressful conditions.
