Possible ecosystem impacts of applying MSY policies from single-species assessment
Ecosim models have been fitted to time-series data for a wide variety of ecosystems for which there are long-term data that confirm the models’ ability to reproduce past responses of many species to harvesting. We subject these model ecosystems to a variety of harvest policies, including options based on harvesting each species at its maximum sustainable yield (MSY) fishing rate. We show that w...
متن کاملPossible impacts of Brexit on EU development and humanitarian policies
Brexit could have a major impact on EU development and humanitarian policies. However, although Brexit is highly likely to happen, there are still uncertainties about the UK’s new foreign policy approach and its repercussions on aid. The UK may act under three different scenarios (nationalist, realist, cosmopolitan) with different consequences for EU aid. The UK’s leaving would challenge the EU...
متن کاملMechanisms of plant species impacts on ecosystem nitrogen cycling
J. M. H. Knops,* K. L. Bradley and D. A. Wedin School of Biological Sciences, School of Natural Resource Sciences, University of Nebraska, 348 Manter Hall, Lincoln, NE 68588, USA. *Correspondence: E-mail: [email protected] Abstract Plant species are hypothesized to impact ecosystem nitrogen cycling in two distinctly different ways.

متن کاملTrait divergence and the ecosystem impacts of invading species.
are induced in plants by a variety of plant-associated rootcolonizing microbes, including plant growth-promoting rhizobacteria, P. indica and mycorrhizal fungi, as summarized in Shoresh et al. (2010). This is, apparently, an example of convergent evolution by very dissimilar organisms. Presumably, the ability of these microbes to induce changes in plants, resulting in a large number of healthy ...
متن کاملApplying the Rapid Management Assessment (rma) Methodology to Ecosystem Management
In the fall of 2002, approximately sixty undergraduate students from a broad range of disciplines at Acadia University enrolled in an interdisciplinary course entitled Sustainable Nova Scotia. While the theoretical and practical implications of this pedagogical approach are to be discussed elsewhere, this paper focuses on one course project that tested the feasibility of the Rapid Management As...
