“…Reports from the North Sea suggest that increasing pCO 2 will benefit gelatinous zooplankton (Attrill et al 2007), but these conclusions are based on environmental correlation rather than experimental observations, and therefore cannot illustrate causality (Haddock 2008). Data for copepods from other parts of the world show that high pCO 2 (2000-2300 latm) did not influence survival, size, development, or egg production of Acartia steueri (Kurihara et al 2004) or of Acartia tsuensis (Kurihara and Ishimatsu 2008), but that extreme values (8000 latm) did influence development (though not growth and egg production) of Calanus finmarchicus (Mayor et al 2007). Modeling suggests that the copepod Pseudocalanus sp.…”

How will Ocean Acidification Affect Baltic Sea Ecosystems? An Assessment of Plausible Impacts on Key Functional Groups

Increasing partial pressure of atmospheric CO 2 is causing ocean pH to fall-a process known as 'ocean acidification'. Scenario modeling suggests that ocean acidification in the Baltic Sea may cause a B3 times increase in acidity (reduction of 0.2-0.4 pH units) by the year 2100. The responses of most Baltic Sea organisms to ocean acidification are poorly understood. Available data suggest that most species and ecologically important groups in the Baltic Sea food web (phytoplankton, zooplankton, macrozoobenthos, cod and sprat) will be robust to the expected changes in pH. These conclusions come from (mostly) single-species and single-factor studies. Determining the emergent effects of ocean acidification on the ecosystem from such studies is problematic, yet very few studies have used multiple stressors and/or multiple trophic levels. There is an urgent need for more data from Baltic Sea populations, particularly from environmentally diverse regions and from controlled mesocosm experiments. In the absence of such information it is difficult to envision the likely effects of future ocean acidification on Baltic Sea species and ecosystems.

“…At acute worst case scenario CO 2 exposures ranging between 72 hours to 9 days there was no reduction in hatching success in the copepod Acartia tsuensis and little sensitivity to elevated CO 2 during any stage of their early development [50], but there was decreased hatching success and increased naupliar mortality of the copepods Acartia erythraea [86] and decreased hatching success of Calanus finmarchicus [95] Table S2. The shrimp Palaemon pacificus also displayed variable responses at different developmental stages, pH and length of exposure [87].…”

Predicting the impact of warming and acidifying on oceans on the early development life history stages of invertebrates although difficult, is essential in order to anticipate the severity and consequences of future climate change. This review summarises the current literature and meta-analyses on the early life-history stages of invertebrates including fertilisation, larval development and the implications for dispersal and settlement of populations. Although fertilisation appears robust to near future predictions of ocean acidification, larval development is much more vulnerable and across invertebrate groups, evidence indicates that the impacts may be severe. This is especially for those many marine organisms which start to calcify in their larval and/or juvenile stages. Species-specificity and variability in responses and current gaps in the literature are highlighted, including the need for studies to investigate the total effects of climate change including the synergistic impact of temperature, and the need for long-term multigenerational experiments to determine whether vulnerable invertebrate species have the capacity to adapt to elevations in atmospheric CO 2 over the next century.

“…This implies that bubbling CO 2 has a much greater effect on egg respiration than using HCl to lower pH, and is in agreement with the results obtained here in which CO 2 had a small yet significant effect at 922 ppm. Mayor et al (2007) showed that elevated CO 2 (8000 ppm) was associated with nearly an 86% reduction in hatching success of copepods despite apparently normal growth and reproduction of adults. In our experiments, there was no impact of elevated CO 2 on hatching success; however, there was an estimated 19 d delay in reaching hatching stage.…”

The effects of CO 2 -induced acidification on survival, shell mineralogy, embryonic development and the timing of larval release were investigated in the intertidal barnacle Semibalanus balanoides using an intertidal microcosm system. Compared to that in the control (CO 2 = 344 ppm, pH = 8.07), adult survival was 22% lower in the high-CO 2 treatment (CO 2 = 922 ppm, pH = 7.70) and significant changes in the mineral structure of the adult shell were observed. Embryonic development rate was significantly slower in the high-CO 2 treatment than in the control but still resembled 'natural' rates seen in populations found in similar locations. There was an estimated 19 d delay in development under high-CO 2 conditions, which resulted in a 60% reduction in the number of nauplii reaching hatching stage at the time when over 50% of the control nauplii had hatched. We conclude that ocean acidification could potentially further compromise embryonic development in a species already stressed by temperature, which could in turn impact naupliar development and recruitment. S. balanoides, the adults of which live in a highly variable environment, has been shown to be detrimentally impacted by a chronic change in chemical conditions (pH lowered beyond the current range) over a crucial period in their life cycle. Under experimental high-CO 2 conditions, some adults were able to survive and larvae were able to hatch. This may indicate that there is still potential for organisms to find suitable habitats and for populations to develop and survive.
