Conservation physiology of marine fishes: linking individual movement with populations and community dynamics in a changing climate
Marine ecosystems are highly size-structured. Fish grow several orders of magnitude in their lifetime, feeding on organisms that are a fraction of their own size. As fish grow larger, their environmental tolerances and movement rates also change influencing the spatial distributions we observe. The environment individual fish experience is also undergoing rapid climatic driven change. The aim of this project is to develop and test new mathematical and statistical approaches to understanding the complex interplay between size-structure and environmental change. Currently, our work focuses on using telemetry data (both tagging and mark-recapture) from a variety of species, most notably cod and porbeagle to test the allometric movement assumptions of these size-structured models. Further work will aim to build on my background of individual based modelling to produce stochastic individual based frameworks that correctly incorporate explicit movement. The results of which will allow us to incorporate more biological realistic movement into size-structure community models. Application will then capture the importance of spatial movement in both past and future change and ultimately evaluate management implications under climate and fishing scenarios.
This project will address the following key questions:
1. Can individual-movement data validate the theoretical assumptions of marine size-structured modelling?
2. Can individual-level processes of movement give rise to patterns in abundance-size-distribution that are consistent with those observed in nature?
3. Does integrating individual-level movement data with dynamic size-structured models help to improve predictions of abundance and distribution for fish assemblages and changes that have occurred at regional and local scales?
4. Does environment-mediated spatial movement affect the coexistence of species and sizes of organisms in local marine communities?
