Session 6. FIS/BIOTopic Session
Observations of ecosystem mixing under climate change

Co-Convenors: Sanae Chiba (Japan), John Field (U.S.A), Jin-Yeong Kim (Korea), Franz Mueter (U.S.A.) and Laura Richards (Canada)

As the ocean environment changes, we expect species to respond by changing their distribution. Species could expand into habitats newly made available to them and avoid or shrink their abundance in habitats that are no longer viable. Because species respond to these environmental changes at different rates, previously isolated species now interact. We coin the term "ecosystem mixing" to describe the pulling apart and re-mixing of ecosystems and species interactions in a changing environment. For example, Humboldt squid, expanded their range northward along the west coast of North America in 2009, encountering new prey species, potentially including important stocks of juvenile salmon. In this session, we consider the consequences of ecosystem mixing. Papers are invited that describe case studies of ecosystem mixing from a physical, biological and/or socio-economic perspective, especially as they impact the predators and/or prey of key species (such as those important for fishery harvests). Selected oral and poster presentations will be considered for publication in a peer-reviewed journal.
