Conference and workshops Ecopath 30 years – Modelling ecosystem dynamics: beyond boundaries with EwE, 4-14 November 2014, Barcelona, Spain.-- 1 page The need to consider changes in natural resources as well as human activities when analysing and managing marine ecosystems highlights the necessity to adopt an integrated view. Since the productivity of marine resources depends on the ecological state of communities and ecosystems, and on external drivers, not only the dynamics of target species, but also the dynamics of non-target organisms, trophic relationships and energy flows, environmental factors and human impacts have to be considered to manage our seas properly. In the last decade, the scientific community made substantial progress in the identification and quantification of multiple human threats that impact marine diversity, habitats, and ecosystems. Currently, there is increasing knowledge on the identification and quantification of these multiple drivers. However, the way these drivers may interact and combine to impact productivity patterns of marine ecosystems is not well known. Multiple drivers may interact and their effects may cause impacts that accumulate in an additive way or may act synergistically or antagonistically at different ecological levels. A comprehensive understanding of these impacts and their interactions is mostly lacking. In addition, multiple impacts are distributed in a heterogeneous way spatially and temporally, and their interactions do not occur the same way everywhere, affecting productivity differently. Moreover, future changes of current human activities (such as climate change, fishing or the invasion of new species), and the appearance and spread of new activities (such as deep sea exploitation), will likely challenge our current understanding. To tackle some of these scientific challenges there is a growing need to develop and use novel methodologies of data integration, assimilation and modelling at different scales, taking into account uncertainties in data and processes. Here we provide an overview of the challenges the scientific community is currently facing to model these cumulative dynamics, on the progress achieved in the last decade and on how novel modelling approaches within the Ecopath with Ecosim approach can contribute to this progress Peer Reviewed 2015-05-18T12:02:19Z 2015-05-18T12:02:19Z 2014-11-11 2015-05-18T12:02:24Z artículo http://purl.org/coar/resource_type/c_6501 issn: 1198-6727 Fisheries Centre Research Reports 22(3): 128 (2014) Ecopath 30 Years Conference Proceedings: Extended Abstracts: 128 (2014) http://hdl.handle.net/10261/115338 http://ewe30.ecopathinternational.org/proceedings/ none |
