Wayne Trivelpiece
Winter temperatures in the Antarctic Peninsula region have increased over the last fifty years, affecting the periodicity of sea ice cover in the region. This climatic change, and its associated reduction in winter sea-ice cover, has profoundly impacted the Antarctic krill-based food web. In his lecture Wayne Trivelpiece will present a conceptual model linking increasing temperatures and decreasing sea ice cover in the Antarctic Peninsula region to declines in krill and Adelie and Chinstrap Penguin populations. He will also discuss his findings suggesting that predator populations, already at risk from climate-driven changes in the food web, are under increasing pressure from recovering whale and seal populations and outdated fisheries quotas.
Trivelpiece is a wildlife biologist with the Antarctic Ecosystem Research Division of the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center.
