Temperature But Not Ocean Acidification Affects Energy Metabolism And Enzyme Activities In The Blue Mussel, Mytilus Edulis, Omera B. Matoo, Gisela Lannig, Christian Bock, Inna M. Sokolova

School of Biological Sciences: Faculty Publications

1. In mosaic marine habitats, such as intertidal zones, ocean acidification (OA) is exacerbated by high variability of pH, temperature, and biological CO2 production. The nonlinear interactions among these drivers can be context-specific and their effect on organisms in these habitats remains largely unknown, warranting further investigation. 2. We were particularly interested in Mytilus edulis (the blue mussel) from intertidal zones of the Gulf of Maine (GOM), USA, for this study. GOM is a hot spot of global climate change (average sea surface temperature (SST) increasing by >0.2°C/year) with >60% decline in mussel population over the past 40 years. 3. …

Temperature Alters Food Web Body-Size Structure, Jean P. Gibert, John P. Delong

School of Biological Sciences: Faculty Publications

The increased temperature associated with climate change may have important effects on body size and predator– prey interactions. The consequences of these effects for food web structure are unclear because the relationships between temperature and aspects of food web structure such as predator–prey body-size relationships are unknown. Here, we use the largest reported dataset for marine predator–prey interactions to assess how temperature affects predator–prey body-size relationships among different habitats ranging from the tropics to the poles. We found that prey size selection depends on predator body size, temperature and the interaction between the two. Our results indicate that (i) predator–prey …
