1. MODELING PREDATION BY TRANSIENT LEOPARD SEALS FOR AN ECOSYSTEM-BASED MANAGEMENT OF SOUTHERN OCEAN FISHERIES

   Abstract:  Correctly quantifying the impacts of rare apex marine predators is essential to ... species and their dependent predators. This requires modelling the uncertainty in such processes as ... prey vulnerability. We combined these uncertainties to evaluate the predatory impact of transient ... assess the implications for an ecosystem-based management. The mesopredators are highly dependent on ...
