Workshop 1. Top predators as indicators of climate change: Statistical techniques, challenges and opportunitiess

Steven J. Bograd (USA)
Elliott Hazen (USA)
Takashi Yamamoto (Japan)

Invited Speakers:
Emanuele Di Lorenzo (Georgia Institute of Technology, USA)
Jeffrey Polovina (Pacific Islands Fisheries Science Center, NOAA-Fisheries, USA)
William J. Sydeman (Farallon Institute for Advanced Ecosystem Research, USA)
Kevin Weng (University of Hawaii at Manoa, USA)

Top predators such as fish, turtles, marine mammals, and seabirds integrate multiple lower trophic level processes and can also exert top-down control of marine food webs. Climate change and variability affect the timing and productivity of pelagic ecosystems. This variability is integrated into the life histories of top predators, potentially affecting their breeding patterns, migration strategies, diets, and ultimately fitness and reproductive success. Pan-Pacific data about top predators are generated by surveys, animal tracking studies, dietary analyses, and measurements of reproductive performance. Environmental and climate data can be synthesized and compared to ecosystem responses in many locations. This workshop invites participants to present and to discuss topics that address: (1) oceanographic and top predator datasets that can be used to examine responses to climate variability and change, (2) statistical techniques that can be used in differentiating top predator responses to climate variability and climate change, (3) identification of sentinel species that respond directly to climate effects and can be used as leading indicators of ecosystem state, and (4) synthetic approaches to understanding how climate variability and change is incorporated in top predator distribution, abundance, or foraging datasets. From the workshop, a pan-Pacific meta-analysis and review paper examining this subject are planned.
