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...
Trends in greater sage-grouse breeding populations are typically indexed by determining the peak number of males attending a lek in a lekking season. Numerous studies have estimated negative trends in sage-grouse breeding populations over time via data collected for the last 50 years. However, the inherent bias in data collection...
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...
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,...
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...
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...
Explains terms and concepts used to discuss ecosystem management (biodiversity, habitat fragmentation, edge effects, interior species, corridors, population dynamics), including a glossary. Describes the importance of private forest lands in the stewardship of forest ecosystems. Provides suggestions for managing private property for wildlife.
