| Summary: | No abstracts are to be cited without prior reference to the author.The Marine Strategy Framework Directive requires EU states to develop indicators characterizing marine environmental status. As acknowledged by the EU Commission in 2010, there is a need to develop indicators that capture the structure of foodwebs. To allow informed management, it is essential that chosen indicators are sensitive to anthropogenic pressures. We consider three species‐resolved foodweb indicators and assess their sensitivity to an increasing fishing mortality rate F, using a multi‐trophic species‐resolved model parameterized for the Northeast Atlantic. This model uses a special algorithm mimicking community assembly, which generates communities with hundreds to thousands of dynamically coexisting model species, reflecting the species richness of real marine foodwebs. Thus, this modelling approach is a highly appropriate method for projecting future states of fished foodwebs to assess the sensitivity of species‐resolved foodweb ... |
