Restoration of marine ecosystems under the impacts of fisheries and climate

My research aims to assess and mitigate the impacts of fisheries on aquatic ecosystems; exploitation in aquatic food webs shifts the balance between schooling pelagic fishes and demersal fish, and hence affects the long-term sustainability of human fisheries. New approaches, methodologies and tools are employed as hypothesis testing engines. In particular my research focusses on how historical reconstruction of past ecosystem states provides quantitative long-term management goals and a template against which management options can be evaluated. The work employs several types of dynamic numerical ecosystem modelling, including spatial models, that allows tests of hypotheses about how fisheries alter the trophic structure, habitat, species diversity, keystone species and life history characteristics of organisms in aquatic ecosystems. This methodology makes it possible to carry out thought-experiments, since real ones are both impractical and
