“…Several of the major space-occupying taxa characteristic of the rocky intertidal zone (mussels, barnacles, coralline algae) are negatively impacted by OA (Kroeker et al, 2013;Kroeker et al, 2014;Ordoñez et al, 2014), which could have significant implications for community succession ( Wootton et al, 2008). Our analysis of the ONP intertidal taxa is consistent with the paradigm that taxa with calcium carbonate structures are more vulnerable to OA than their non-coralline, fleshy algal neighbors (Guinotte and Fabry, 2008;Kroeker et al, 2010).…”

Ocean acidification (OA) will have a predominately negative impact on marine animals sensitive to changes in carbonate chemistry. Coastal upwelling regions, such as the Northwest coast of North America, are likely among the first ecosystems to experience the effects of OA as these areas already experience high pH variability and naturally low pH extremes. Over the past decade, pH off the Olympic coast of Washington has declined an order of magnitude faster than predicted by accepted conservative climate change models. Resource managers are concerned about the potential loss of intertidal biodiversity likely to accompany OA, but as of yet, there are little pH sensitivity data available for the vast majority of taxa found on the Olympic coast. The intertidal zone of Olympic National Park is particularly understudied due to its remote wilderness setting, habitat complexity, and exceptional biodiversity. Recently developed methodological approaches address these challenges in determining organism vulnerability by utilizing experimental evidence and expert opinion. Here, we use such an approach to determine intertidal organism sensitivity to pH for over 700 marine invertebrate and algal species found on the Olympic coast. Our results reinforce OA vulnerability paradigms for intertidal taxa that build structures from calcium carbonate, but also introduce knowledge gaps for many understudied species. We furthermore use our assessment to identify how rocky intertidal communities at four long-term monitoring sites on the Olympic coast could be affected by OA given their community composition. the park's general management plan (NPS, 2007). The 65-mile coastline is a UNESCO Biosphere Reserve and World Heritage Site that hosts one of the most biodiverse assemblages of marine invertebrates and seaweeds along the west coast of North America (Schoch et al., 2006). The intertidal zone is comprised of rocky reefs, sandy beaches, and cobble boulder fields and is valued regionally and nationally for its ecological, economic, and cultural significance. The loss of species in the intertidal zone that rely on a particular pH threshold or the availability of CO 3 2− could fundamentally alter one or all of these interests (Cooley et al., 2009;Lynn et al., 2013) and have resounding reverberations for marine food webs (Gaylord et al., 2015). Over the past decade, ocean pH off the Olympic coast has declined an order of magnitude faster than predicted by accepted conservative climate change models (Feely et al., 2004;Wootton and Pfister, 2012) and has impacted marine aquaculture in the region (Barton et al., 2015). These observations spurred the Governor of Washington to form a Blue Ribbon Panel on Ocean Acidification. The panel's report (Washington Department of Ecology, 2012) recommended expanded pH monitoring and an assessment of marine resource sensitivity to OA. Although OA-associated impacts are documented for several cosmopolitan species, a major limitation for resource managers is determining how those impacts will be experience...

“…When exposed to acidified seawater, marine calcifiers often allocate more energy to essential physiological processes, such as acid-base homeostasis, which will negatively affect the growth, reproduction and defence of these species (Kroeker et al, 2014;Wood et al, 2008). The disturbance of ion and acid-base regulation indirectly inhibits biomineralization by influencing energy and ion supplies for CaCO 3 deposition processes.…”

“…On the one hand, the mechanical properties of the shell are critical in protecting the shelled molluscs from damage caused by predation and environmental changes. Changes in M. edulis shells are likely to influence predator-prey dynamics in coastal ecosystems (Kroeker et al, 2014). On the other hand, changes in amino acids will alter the nutritional component of the edible parts, which might also influence predator-feeding behaviour at higher trophic levels in the marine food chain.…”

Seawater acidification and warming resulting from anthropogenic production of carbon dioxide are increasing threats to marine ecosystems. Previous studies have documented the effects of either seawater acidification or warming on marine calcifiers; however, the combined effects of these stressors are poorly understood. In our study, we examined the interactive effects of elevated carbon dioxide partial pressure (P CO2 ) and temperature on biomineralization and amino acid content in an ecologically and economically important mussel, Mytilus edulis. Adult M. edulis were reared at different combinations of P CO2 ( pH 8.1 and 7.8) and temperature (19, 22 and 25°C) for 2 months. The results indicated that elevated P CO2 significantly decreased the net calcification rate, the calcium content and the Ca/Mg ratio of the shells, induced the differential expression of biomineralization-related genes, modified shell ultrastructure and altered amino acid content, implying significant effects of seawater acidification on biomineralization and amino acid metabolism. Notably, elevated temperature enhanced the effects of seawater acidification on these parameters. The shell breaking force significantly decreased under elevated P CO2 , but the effect was not exacerbated by elevated temperature. The results suggest that the interactive effects of seawater acidification and elevated temperature on mussels are likely to have ecological and functional implications. This study is therefore helpful for better understanding the underlying effects of changing marine environments on mussels and other marine calcifiers.

Tropical coral reef organisms are predicted to be especially sensitive to ocean warming because many already live close to their upper thermal limit, and the expected rise in ocean CO 2 is proposed to further reduce thermal tolerance. Little, however, is known about the thermal sensitivity of a diverse and abundant group of reef animals, the gastropods. The humpbacked conch (Gibberulus gibberulus gibbosus), inhabiting subtidal zones of the Great Barrier Reef, was chosen as a model because vigorous jumping, causing increased oxygen uptake (Ṁ O2 ), can be induced by exposure to odour from a predatory cone snail (Conus marmoreus). We investigated the effect of present-day ambient (417-454 µatm) and projected-future (955-987 µatm) P CO2 on resting (Ṁ O2,rest ) and maximum (Ṁ O2,max ) Ṁ O2 , as well as Ṁ O2 during hypoxia and critical oxygen tension (P O2,crit ), in snails kept at present-day ambient (28°C) or projectedfuture temperature (33°C). Ṁ O2,rest and Ṁ O2,max were measured both at the acclimation temperature and during an acute 5°C increase. Jumping caused a 4-to 6-fold increase in Ṁ O2 , and Ṁ O2,max increased with temperature so that absolute aerobic scope was maintained even at 38°C, although factorial scope was reduced. The humpbacked conch has a high hypoxia tolerance with a P O2,crit of 2.5 kPa at 28°C and 3.5 kPa at 33°C. There was no effect of elevated CO 2 on respiratory performance at any temperature. Long-term temperature records and our field measurements suggest that habitat temperature rarely exceeds 32.6°C during the summer, indicating that these snails have aerobic capacity in excess of current and future needs.
