The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning with a planning...
Microbial communities in Arctic coastal lagoons drive biogeochemical cycles at the terrestrial-marine interface and help to determine the fate and form of resources like nitrogen (N) and carbon (C) as they are delivered to the Arctic Ocean. Though rising rates of primary production in the Arctic Ocean are well-characterized, the...
There is increasing concern among fisheries scientists and managers over
the ecosystem effects of fisheries exploitation. This concern has been
motivated by several publications inferring that the structure of marine
ecosystems has been dramatically altered by historical patterns of fishing.
Among the most cited studies is the paper by Pauly...
Modern fisheries management is strongly based on ecosystem theory. Ecosystem management involves direct manipulation of the habitat and population as well as human activity in order to optimize sustainable returns to humans. The ecosystems approach is widely viewed as a new concept in management of fisheries and aquaculture. Ecosystems based...
Marine scientists and policymakers are encouraging ecosystem-based fishery management (EBFM), but there is limited guidance on how to operationalize the concept. We develop a method for EBFM based on financial asset management that uses the joint probability distribution of species in an ecosystem. Illustrating our method with the Chesapeake Bay,...
Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
Large-scale ecosystem assessments aim to assist ecosystem management by synthesizing current scientific knowledge on an area, and by providing a foundation for policy discussions and decisions on land management. These assessments go beyond traditional research efforts by moving away from narrow scope, system, and institutional boundaries, and by attempting to...
