Dr. Jeremy Kiszka

Summary

Dr. Kiszka studies the ecological roles and importance of marine mammals and other large marine vertebrates (sea turtles, elasmobranchs) in a variety of marine ecosystems. More specifically, he investigates how they use habitats and resources (their ecological roles) and how ecosystems can be affected by the presence of these animals, which includes their top down effects on resources and behavior, as well as nutrient dynamics. Empirical studies and a rich theoretical framework also demonstrate marine megafauna can affect ecosystems through more diverse pathways, including those that are driven by behavior.

For example, Dr. Kiszka studies the roles of cetaceans, green turtles and several species of elasmobranchs in facilitating access to resources to other species (e.g. teleosts, seabirds), and how mixed-species associations can affect community dynamics. His work implies the use and development of new and innovative research tools and methods to study marine megafauna ecology and conservation issues, particularly since these species are so challenging to observe. Through research and education, he also creates outreach tools and works on providing opportunities for students from minority groups and developing countries to build capacity.

Previously

Expertise

Dr. Kiszka has advised the International Union for the Conservation of Nature, the International Whaling Commission, the US Marine Mammal Commission, and the Indian Ocean Tuna Commission among others. He has also written several IUCN Red List Assessments for cetaceans, as part of his activities within the Cetacean Specialist Group of IUCN. He regularly attends the Working Party on Ecosystems and Bycatch at the Indian Ocean Tuna Commission, particularly to address marine mammal threats and management issues in the Indian Ocean.
