AH51A:
Assessing the Cumulative Effects of Complex Ocean Change on Marine Biota I


Session ID#: 11388

Session Description:
Oceanic conditions are changing at an unprecedented rate due to anthropogenically-driven changes. Life in the ocean will increasingly have to contend with a complex matrix of concurrent shifts in properties that set their physiology and control their life histories. This matrix of change will have a combined influence on marine biota, due to both the individual effects of altered properties such as warming, but also due to the interactions between these properties. A further challenge to studying the cumulative effects of anthropogenic change will be the identification of the interactions of local, regional and global scales of such change. We invite abstracts to this session from studies which highlight how this multiplicity of factors can be addressed and will alter organismal physiology, biogeochemical cycles and/or food-webs. Theoretical, experimental and modelling approaches are welcome.
