Dispersal is a key ecological process that enables local populations to form spatially extended systems called metapopulations. In the present study, we investigate how dispersal affects the linear stability of a general single-species metapopulation model. We discuss both the influence of local within-patch dynamics and the effects of various disp...
This article examines the role of risk aversion on the sustainable management of mixed fisheries. We consider a bio-economic model of multiple species harvested by a single fleet with uncertain costs of effort. We assume that the regulatory agency aims at reaching MMEY (Multispecies Maximum Economic Yield) by maximizing the expected utility of tota...
As marine ecosystems are under pressure worldwide, many scientists and stakeholders advocate the use of ecosystem-based approaches for fishery management. In particular, management policies are expected to account for the multispecies nature of fisheries. However, numerous fisheries management plans remain based on single-species concepts, such as...
La surpêche affecte les structures et dynamiques de nombreux écosystèmes marins, ainsi que les services écosystémiques qui en dépendent. En réponse, scientifiques et gestionnaires plaident pour une gestion écosystémique des pêches, intégrant la complexité des écosystèmes exploités, et fondée sur des objectifs de durabilité écologiques comme économi...

Many world fisheries display a declining mean trophic level of catches. This "fishing down the food web" is often attributed to reduced densities of high-trophic-level species, reflecting changes in the structure of harvested food webs. However, this pattern can also result from a restructuring of the fishery, that shifts from a focus on depleted u...
This paper examines the role of risk aversion on the sustainable management of multispecies fisheries with technical interactions. We consider a bio-economic dynamic model of multiple species harvested by a single fleet with uncertain costs of effort. We assume that the regulatory agency aims at reaching MMEY (Multispecies Maxi-mum Economic Yield)...
The global overexploitation of fish stocks is endangering many marine food webs. Scientists and managers now call for an ecosystem-based fisheries management, able to take into account the complexity of marine ecosystems and the multiple ecosystem services they provide. By contrast, many fishery management plans only focus on maximizing the product...
