“…Our multistressor study showed, however, that interactive effects of these stressors influenced the outcome for development in a warmer and higher pCO 2 ocean. A 28C warming diminished the negative influence of lowered pH on juvenile calcification in H. erythrogramma, similar to that seen for echinoplutei of Tripneustes gratilla reared in similar multifactoral experiments [9]. Owing to the interdependence between temperature, mineral saturation state and pH, the mechanism of this facilitation is likely to be complex.…”

“…These juveniles were thus able to maintain a high calcium carbonate saturation state at the calcification site to make the test and spines. Owing to enhanced maternal provisioning and deletion of the echinopluteus larva, a developmental stage negatively affected by ocean acidification [9,16,20], H. erythrogramma is independent of the need to produce a functional larval skeleton [38]. Development of the lecithotrophic larvae of the sea star Crossaster papposus is also robust to low pH conditions [12].…”

The most fragile skeletons produced by benthic marine calcifiers are those that larvae and juveniles make to support their bodies. Ocean warming, acidification, decreased carbonate saturation and their interactive effects are likely to impair skeletogenesis. Failure to produce skeleton in a changing ocean has negative implications for a diversity of marine species. We examined the interactive effects of warming and acidification on an abalone (Haliotis coccoradiata) and a sea urchin (Heliocidaris erythrogramma) reared from fertilization in temperature and pH/pCO 2 treatments in a climatically and regionally relevant setting. Exposure of ectodermal (abalone) and mesodermal (echinoid) calcifying systems to warming (þ28C to 48C) and acidification (pH 7.6 -7.8) resulted in unshelled larvae and abnormal juveniles. Haliotis development was most sensitive with no interaction between stressors. For Heliocidaris, the percentage of normal juveniles decreased in response to both stressors, although a þ28C warming diminished the negative effect of low pH. The number of spines produced decreased with increasing acidification/pCO 2 , and the interactive effect between stressors indicated that a þ28C warming reduced the negative effects of low pH. At þ48C, the developmental thermal tolerance was breached. Our results show that projected near-future climate change will have deleterious effects on development with differences in vulnerability in the two species.

“…First, the effects of ocean acidification are exacerbated in the presence of elevated temperature (Reynaud et al 2003;Metzger et al 2007;Anthony et al 2008;Byrne et al 2009;Gooding et al 2009;Martin and Gattuso 2009;Munday et al 2009). Second, the effects of ocean acidification are ameliorated in the presence of elevated temperature (Brennand et al 2010). Higher temperature and higher salinity mitigated the impacts of reduced pH (-0.5 pH unit) on the calcification of juvenile C. virginica (Waldbusser et al 2011b).…”

Impacts of ocean acidification on marine shelled molluscs

Over the next century, elevated quantities of atmospheric CO 2 are expected to penetrate into the oceans, causing a reduction in pH (-0.3/-0.4 pH unit in the surface ocean) and in the concentration of carbonate ions (so-called ocean acidification). Of growing concern are the impacts that this will have on marine and estuarine organisms and ecosystems. Marine shelled molluscs, which colonized a large latitudinal gradient and can be found from intertidal to deep-sea habitats, are economically and ecologically important species providing essential ecosystem services including habitat structure for benthic organisms, water purification and a food source for other organisms. The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of a general picture. This is, however, not the case for pteropods, with all species tested so far, being negatively impacted by ocean acidification. The blood of shelled molluscs may exhibit lower pH with consequences for several physiological processes (e.g. respiration, excretion, etc.) and, in some cases, increased mortality in the long term. While fertilization may remain unaffected by elevated pCO 2 , embryonic and larval development will be highly sensitive with important reductions in size and decreased survival of larvae, increases in the number of abnormal larvae and an increase in the developmental time. There are big gaps in the current understanding of the biological consequences of an Communicated by S. Dupont.Frédéric Gazeau and Laura M.

“…Aragonite saturation horizons will occur at shallower depths in future, especially in the Antarctic and Australian southern margins, threatening a wide range of larval and adult benthic and pelagic calcifying organisms (e.g. Przeslawski et al 2008;Sheppard Brennand et al 2010).…”

Abstract. Changes in the physical environment of aquatic systems consistent with climate change have been reported across Australia, with impacts on many marine and freshwater species. The future state of aquatic environments can be estimated by extrapolation of historical trends. However, because the climate is a complex non-linear system, a more process-based approach is probably required, in particular the use of dynamical projections using climate models. Because global climate models operate on spatial scales that typically are too coarse for aquatic biologists, statistical or dynamical downscaling of model output is proposed. Challenges in using climate projections exist; however, projections for some marine and freshwater systems are possible. Higher oceanic temperatures are projected around Australia, particularly for south-eastern Australia. The East Australia Current is projected to transport greater volumes of water southward, whereas the Leeuwin Current on the western coast may weaken. On land, projections suggest that air temperatures will rise and rainfall will decline across much of Australia in coming decades. Together, these changes will result in reduced runoff and hence reduced stream flow and lake storage. Present climate models are particularly limited with regard to coastal and freshwater systems, making the models challenging to use for biological-impact and adaptation studies.
