Research project: Trophic and Spacial Ecology of Marine Predators

Currently Active: 
Yes

Stable isotopes (e.g. C, N, O, H, S) provide a wealth of ecological information on diet, location and physiological condition of animals. We are interested in all applications of stable isotopes to ecology, particularly in marine systems.

Project Overview

Spatial Ecology

We have pioneered the use of co-varying time series of carbon isotopes and environmental drivers to identify feeding grounds and migration routes in pelagic marine predators.

Historic trends in ecosystem function

Tissues of high trophic level animals integrate an isotopic record of ecosystem structure and function.

We are exploring the use of stable isotope time series to identify bottom-up controls on ecosystem function.

Modelling Marine Isoscapes

We are developing global models to predict spatial distribution and temporal variability in stable isotopes in primary producers. These models will be used to track marine animals and explore the predicted effects of climate change on tissue isotopes.
