“…A negative effect on reproduction, however, was reported only for conditions above 5,000 latm (Kurihara and Ishimatsu 2008). The mortality of larval stages was also found to increase with increasing pCO 2 and decreasing pH in some cases (Kurihara et al 2004). It therefore appears that the younger stages of copepods are the most vulnerable, both to the direct (acidification) and the indirect (food quality) effects of increased pCO 2 .…”

“…Several studies have investigated the direct effects of ocean acidification on copepods, although effects varied between species copepods were affected by high pCO 2 , especially after longer exposure (Watanabe et al 2006). While elevated pCO 2 did not seem to affect the adult copepods tested (Kurihara and Ishimatsu 2008;Kurihara et al 2004;Mayor et al 2007), hatching rates were negatively affected by high pCO 2 and low pH (Kurihara et al 2004;Mayor et al 2007). A negative effect on reproduction, however, was reported only for conditions above 5,000 latm (Kurihara and Ishimatsu 2008).…”

Increased carbon dioxide availability alters phytoplankton stoichiometry and affects carbon cycling and growth of a marine planktonic herbivore

et al. 2012

Rising levels of CO 2 in the atmosphere have led to increased CO 2 concentrations in the oceans. This enhanced carbon availability to the marine primary producers has the potential to change their nutrient stoichiometry, and higher carbon-to-nutrient ratios are expected. As a result, the quality of the primary producers as food for herbivores may change. Here, we present experimental work showing the effect of feeding Rhodomonas salina grown under different pCO 2 (200, 400 and 800 latm) on the copepod Acartia tonsa. The rate of development of copepodites decreased with increasing CO 2 availability to the algae. The surplus carbon in the algae was excreted by the copepods, with younger stages (copepodites) excreting most of their surplus carbon through respiration and adult copepods excreting surplus carbon mostly as DOC. We consider the possible consequences of different excretory pathways for the ecosystem. A continued increase in the CO 2 availability for primary production, together with changes in the nutrient loading of coastal ecosystems, may cause changes in the trophic links between primary producers and herbivores.

“…An increase in larval mortality and a decrease in hatching success under elevated seawater PCO 2 have been observed in two species of marine copepods (Kurihara et al 2004). Other crustacean larvae showed altered growth and calcification rates at high seawater CO 2 concentrations at 1,200-3,000 latm (Arnold et al 2009, Walther et al 2010.…”

Tolerance of Hyas araneus zoea I larvae to elevated seawater PCO2 despite elevated metabolic costs

et al. 2012

Early life stages of marine crustaceans respond sensitively to elevated seawater PCO 2 . However, the underlying physiological mechanisms have not been studied well. We therefore investigated the effects of elevated seawater PCO 2 on oxygen consumption, dry weight, elemental composition, median developmental time (MDT) and mortality in zoea I larvae of the spider crab Hyas araneus (Svalbard 79°N/11°E; collection, May 2009; hatch, December 2009). At the time of moulting, oxygen consumption rate had reached a steady state level under control conditions. In contrast, elevated seawater PCO 2 caused the metabolic rate to rise continuously leading to a maximum 1.5-fold increase beyond control level a few days before moulting into the second stage (zoea II), followed by a pronounced decrease. Dry weight of larvae reared under high CO 2 conditions was lower than in control larvae at the beginning of the moult cycle, yet this difference had disappeared at the time of moulting. MDT of zoea I varied between 45 ± 1 days under control conditions and 42 ± 2 days under the highest seawater CO 2 concentration. The present study indicates that larval development under elevated seawater PCO 2 levels results in higher metabolic costs during premoulting events in zoea I. However, H. araneus zoea I larvae seem to be able to compensate for higher metabolic costs as larval MDT and survival was not affected by elevated PCO 2 levels.

Studies to date have demonstrated a number of potentially important effects including reduced growth rates (Gazeau et al, 2007), decreased reproductive success (Kurihara et al, 2004b), shell dissolution (Bamber, 1990) as well as acidification of internal body fluids , compromise of induced defences (Bibby et al, 2007), increased susceptibility to infection (Holman et al, 2004) and impairment of immune function (Bibby et al, 2008). Unfortunately the majority of these studies have investigated short-term responses with most attention being paid to effects on adult organisms alone.…”

Effect of CO<sub>2</sub>-related acidification on aspects of the larval development of the European lobster, <i>Homarus gammarus</i> (L.)

et al. 2009

Abstract. Oceanic uptake of anthropogenic CO 2 results in a reduction in pH termed "Ocean Acidification" (OA). Comparatively little attention has been given to the effect of OA on the early life history stages of marine animals. Consequently, we investigated the effect of culture in CO 2 -acidified sea water (approx. 1200 ppm, i.e. average values predicted using IPCC 2007 A1F1 emissions scenarios for year 2100) on early larval stages of an economically important crustacean, the European lobster Homarus gammarus. Culture in CO 2 -acidified sea water did not significantly affect carapace length of H. gammarus. However, there was a reduction in carapace mass during the final stage of larval development in CO 2 -acidified sea water. This co-occurred with a reduction in exoskeletal mineral (calcium and magnesium) content of the carapace. As the control and high CO 2 treatments were not undersaturated with respect to any of the calcium carbonate polymorphs measured, the physiological alterations we record are most likely the result of acidosis or hypercapnia interfering with normal homeostatic function, and not a direct impact on the carbonate supply-side of calcification per se. Thus despite there being no observed effect on survival, carapace length, or zoeal progression, OA related (indirect) disruption of calcification and carapace mass might still adversely affect the competitive fitness and recruitment success of larval lobsters with serious consequences for population dynamics and marine ecosystem function.
