Complexity, Connectivity, and Change in Southern Ocean Food Webs I
Session ID#: 93116
Session Description:
Changes in ice, ocean and ecosystem dynamics in the Southern Ocean are affecting biodiversity at all trophic levels, from plankton to whales. These reflect multiple drivers of change and the complexity and heterogeneity of ecosystems and ecological responses. Food-web processes are fundamental in maintaining the structure, functioning and resilience of ecosystems and hence in ecological responses to change. Improved understanding of Southern Ocean food webs is crucial for developing models to project the impacts of future change and informing decision making for conservation and management. An international and interdisciplinary approach is required to link studies of food webs with analyses of biogeochemical cycles and physical and chemical processes at multiple scales. This session is intended to bring together studies on emerging areas of research including the spatial and temporal variability and connectivity of food webs, food web resilience properties and biodiversity, interactions between pelagic, sea-ice or benthic food webs, importance of food-web processes in biogeochemical cycles (including carbon budgets) and combined effects of past and current harvesting and climate-related changes on individual species and their food web interactions. Presentations that report field, data syntheses and modelling studies that elucidate the structure and dynamics of Southern Ocean food webs are encouraged.
