A public lecture by Dr Craig Purchase, Associate Professor of Biology, Memorial University of Newfoundland and IAS Visiting Fellow.
About 30 years ago, the Northwest Atlantic Ocean foodweb was uprooted with the collapse of cod stocks, and continues to undergo substantial change. Capelin are the most important fish in the region, converting zooplankton protein to forage for larger fish, seabirds and marine mammals. Major shifts in life history characteristics of capelin occurred in the early 90s concomitant with a biomass collapse, which has not recovered. In this talk, Dr Purchase will discuss his research on capelin reproduction, and how evolutionary constraints may underpin the observed changes in ecosystem functioning.
