You can use the Project Search Tool below to browse over the staff’s research projects, including their brief summaries, that are currently under way, or planned for the near future and funded under the 5-year Strategic Science Plan (2019-2023). The summaries include, for each project, background information, a work plan, and a progress report, as well as details of its relevance and purpose, external collaborators, duration, and deliverables; also, for existing projects, an update on activities since the previous year’s report.

4 Project(s)N.2.a - Develop models of the effects of climate change on pre-recruit life stages of tropical tunas01 Jan 2018 - 31 Dec 2022FundedObjectives:
Investigate experimentally the effects of important climate change factors on early life stages of tropical tunas, and incorporate those results into models that can predict climate change effects on the distribution and abundance of tropical tunasO.2.a - Develop and implement analytical tools for understanding the trophic ecology of apex predators01 Jun 2018 - 01 Apr 2019FundedObjectives:
O.2.b - An updated ecosystem model of the tropical EPO for providing standardized ecological indicators for monitoring of ecosystem integrity01 Jun 2018 - 30 May 2021FundedObjectives:
- To further develop and validate statistical tools for the analysis of complex datasets in trophic studies of apex predators.
- To enhance external collaborations and professional development through the analysis of Atlantic bluefin tuna diets in relation to biological and environmental variables.
01 May 2021 - 31 May 2023FundedObjectives:
- Update the Ecopath ecosystem model developed for the eastern tropical Pacific Ocean (ETP) by Olson and Watters (2003).
- Convert the model to Ecopath with Ecosim (EwE) software version 6.5.
- Update the model with annual catch, discards, fishing mortality and fishing effort data for each functional group from 1993 to present.
- Calibrate the model with new catch and effort time series to improve the reliability of model forecast outputs.
- Produce annual ecological indicators for inclusion in the Ecosystems Considerations report as standardized measures of ecosystem integrity.
- Investigate the connectivity among bycatch species caught in the purse-seine fishery and how the structure of these community relationships changes over time and space (if feasible) in the eastern Pacific Ocean (EPO).
- Investigate the vulnerability of those connections and the role of key bycatch species for the community/network
