Gulf Apex Predator-Prey Project

Current Researchers

Kate Wynne

Professor, Marine Advisory Program Marine Mammal Specialist

Ms. Wynne is responsible for integrating marine mammal research objectives into GAP's overall goals and coordinating collaboration with particular focus on pinniped foraging ecology. She continues to collaborate with state and federal biologists studying Steller sea lion, harbor seal, and cetacean populations and their interactions with fisheries in the Aleutians and Gulf of Alaska.

Briana Witteveen, Ph.D.

Assistant Research Professor, Marine Advisory Program Marine Mammal Specialist

Dr. Witteveen earned her M.S. through the GAP project and has continued to work for the project as a technician, postdoc, and now a research professional. She is responsible for GAP projects relating to the foraging ecology and population dynamics of large whales. Additionally, she synthesizes previously collected data on species at upper trophic levels from GAP and other studies for input into ecosystem models to address questions regarding the impact of changes in the abundance of and consumption by baleen whale populations throughout defined time scales.

Lei Guo, Ph.D.

Postdoctoral Fellow

Dr. Guo earned his Ph.D. through the GAP project and began his work as a postdoc in March 2011. The goals of his postdoc are twofold:

  1. To continue monitoring seasonal distribution of forage fishes and macro-zooplankton in waters around the Kodiak archipelago through field surveys and laboratory analyses. Surveys are designed to spatially overlap with concurrent GAP studies of marine mammals, such as Stellar sea lions and humpback whales.
  2. To synthesize previously collected data on physical oceanography and species at lower trophic levels from GAP and other relevant studies. Output will be interfaced with synthesized data on apex predators in local ecosystems to establish conceptual models.
