    Targets and limits for long-term management are used in fisheries advice to operationalize the way management reflects societal priorities on ecological, economic, social and institutional aspects. This study reflects on the available published literature as well as new research presented at the international ICES/Myfish symposium on targets and limits for long term fisheries management. We examine the inclusion of ecological, economic, social and institutional objectives in fisheries management, with the aim of progressing towards including all four objectives when setting management targets or limits, or both, for multispecies fisheries. The topics covered include ecological, economic, social and governance objectives in fisheries management, consistent approaches to management, uncertainty and variability, and fisheries governance. We end by identifying ten ways to more effectively include multiple objectives in setting targets and limits in ecosystem based fisheries management

    A generic approach to develop a trait-based indicator of trawling-induced disturbance

    Biological trait analysis has become a popular tool to infer the vulnerability of benthic species to trawling-induced disturbance. Approaches using multiple traits are being developed, but their generic relevance across faunal components and geographic locations remains poorly tested, and the importance of confounding effects are poorly recognised. This study integrates biological traits of benthic species that are responsive to instantaneous effects of trawling (i.e. sensitivity) and traits expressing recoverability over the longer term (i.e. years). We highlight the functional independence between these 2 components in response to trawling, test the behaviours of single and combined traits and account for potential confounding effects of environment and trawling intensity on benthic communities through variation partitioning. Two case studies are considered: epibenthos from the Bay of Biscay and endobenthos of the Dutch sector of the North Sea. The response to trawling is most pronounced when multiple traits covering different aspects that determine population dynamics (i.e. sensitivity and recoverability) are combined, despite confounding effects between gradients of benthic production and trawling intensity, especially for endobenthos. The integration of traits reflecting both sensitivity and recoverability provides complementary information on the faunal response to trawling, bridging the gap between fishing impact assessments and benthic community status assessment

    Lysine glutarylation, a new protein posttranslational modification (PTM), was recently identified and characterized in both prokaryotic and eukaryotic cells. To explore the distribution of lysine glutarylation in <i>Mycobacterium tuberculsosis</i>, by using a comprehensive method combining the immune affinity peptide enrichment by the glutaryl-lysine antibody with LC–MS, we finally identified 41 glutarylation sites in 24 glutarylated proteins from <i>M. tuberculosis</i>. These glutarylated proteins are involved in various cellular functions such as translation and metabolism and exhibit diverse subcellular localizations. Three common glutarylated proteins including 50S ribosomal protein L7/L12, elongation factor Tu, and dihydrolipoamide succinyltransferase are shared between <i>Escherichia coli</i> and <i>M. tuberculosis</i>. Moreover, comparison with other PTMs characterized in <i>M. tuberculosis</i>, 15 glutarylated proteins, are found to be both acetylated and succinylated. Notably, several stress-response-associated proteins including HspX are glutarylated. Our data provide the first analysis of <i>M. tuberculosis</i> lysine glutarylated proteins. Further studies on the role of the glutarylated proteins will unveil the molecular mechanisms of glutarylation underlying <i>M. tuberculosis</i> physiology and pathogenesis
