Our program focuses on the study of marine turtles, with emphasis in four primary disciplines including determination of (1) sea turtle population vital rates, (2) sea turtle population genetics, (3) sea turtle movements and habitat use, and (4) anthropogenic impacts to sea turtle populations. These efforts focus on the eastern Pacific, western Pacific, and western North Atlantic, although we also address biological questions in other areas as dictated by agency needs. In addition to empirical data collection, researchers conduct status assessments under the US Endangered Species Act and IUCN Red List. Where appropriate, we develop novel analytical approaches and quantitative tools to describe marine turtle population status and trends. These efforts invoke multiple lines of evidence (e.g., genetics, stable isotopes, vital rates, satellite telemetry, and climate) and integrate anthropogenic impacts to develop spatially explicit marine turtle stock assessments. Our program would like to further characterize the vital rates of sea turtle populations in the Pacific and Atlantic Oceans through use of tools such as fatty acid analysis, hormone analysis, skeletochronology, and stable isotope analysis (e.g., Avens et al. 2013, Allen et al. 2015). Therefore, we invite proposals that examine novel approaches to study sea turtle vital rates such as age, sex ratio, somatic growth, age-to-maturity, and age-at-neritic-recruitment. Efforts outlining integrative approaches to assessing vital rates would be especially appropriate for an Associate.
