TITLE: Zooplankton links to fisheries in a changing ocean
Globally, analyses of long term observational datasets are revealing large shifts in zooplankton communities in response to changes in climate, with important implications for fisheries and ecosystems. My research focuses on diagnosing the effects of environmental change on zooplankton distribution, behavior, species composition, and growth, along with the associated changes in food webs. Physical and chemical changes in the ocean that act on marine ecosystems through bottom-up processes are occurring across a wide variety of scales. I will present results of my research that demonstrate the importance of time series observations, in combination with short term process studies, to form hypotheses and test specific pathways of ecosystem change—from global changes in ocean pH, regional changes in horizontal advection, and local changes in seasonal oxygen dynamics. These studies provide mechanistic frameworks for understanding how climate variability can affect fisheries and ecosystems through changes in zooplankton.
