“…Both adult and larvae of M. galloprovincialis seem to be sensitive to temperatures higher than [24][25][26] • C, after which the growth decreases and mortality increases [14,95,100]. Adaptation of M. galloprovincialis populations to temperatures of their respective habitats could explain the observed difference between previous studies [94][95][96][97] and our results.…”

Larval stages are among those most vulnerable to ocean acidification (OA). Projected atmospheric CO 2 levels for the end of this century may lead to negative impacts on communities dominated by calcifying taxa with planktonic life stages. We exposed Mediterranean mussel (Mytilus galloprovincialis) sperm and early life stages to pH T levels of 8.0 (current pH) and 7.6 (2100 level) by manipulating pCO 2 level (380 and 1000 ppm). Sperm activity was examined at ambient temperatures (16-17• C) using individual males as replicates. We also assessed the effects of temperature (ambient and ≈20• C) and pH on larval size, survival, respiration and calcification of late trochophore/early D-veliger stages using a cross-factorial design. Increased pCO 2 had a negative effect on the percentage of motile sperm (mean response ratioR = 71%) and sperm swimming speed (R = 74%),Water 2013, 5 1891 possibly indicating reduced fertilization capacity of sperm in low concentrations. Increased temperature had a more prominent effect on larval stages than pCO 2 , reducing performance (R Size = 90% andR Survival = 70%) and increasing energy demand (R Respiration = 429%). We observed no significant interactions between pCO 2 and temperature. Our results suggest that increasing temperature might have a larger impact on very early larval stages of M. galloprovincialis than OA at levels predicted for the end of the century.

“…Our results also suggest that the interaction of seawater acidification and elevated temperature led to further depression of amino acid metabolism. Exposure to high temperatures that exceed optimum growth conditions can result in metabolic depression in the mussels Modiolus barbatus (Anestis et al, 2008) and M. galloprovincialis (Anestis et al, 2010). In our study, long-term temperature exposure cumulatively increased the inhibitory effects of seawater acidification on amino acid metabolism in M. edulis.…”

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.

“…After vortexing for 15 min and subsequent centrifugation for 10 min at 1,500 g, we transferred the supernatants into microcentrifuge tubes and stored them at Ϫ20ЊC until assayed (Ganswindt et al 2010b). We determined the organic content of each sample according to the procedure described by Anestis et al (2010). After the extracted fecal pellets were air-dried at room temperature under a fume cupboard for at least 48 h, we weighed (AT261 Delta Range; Mettler-Toledo) the dried fecal material again (initial weight).…”

We evaluated two different enzyme immunoassays (EIAs) for the noninvasive evaluation of adrenocortical activity in ground-feeding aardwolves (Proteles cristata) and tested the influence of soil content in aardwolf feces on the interpretation of fecal glucocorticoid metabolite data. Using adrenocorticotropic hormone (ACTH) challenges for validation, we successfully identified a cortisol EIA suitable for assessing adrenocortical activity in aardwolves. An alternatively tested 11-oxoetiocholanolone EIA failed to detect a biologically relevant signal after ACTH administration. Although the proportion of inorganic content in aardwolf feces did not alter qualitative conclusions from the endocrine data, the data related to mass of organic content had a larger amount of variance attributed to relevant biological contrasts and a lower amount of variance attributed to individual variation, compared with data related to total dry mass of extracted material. Compared with data expressed as dry mass of extracted material, data expressed as mass of organic content may provide a more refined and statistically powerful measure of endocrine activity in species that ingest large amounts of indigestible material.
