Technical mitigation measures to reduce the bycatch of sharks: there is no silver bulletNARA Subscribed
Incidental catch (bycatch) of sharks in commercial fisheries is driving global population declines. In this review we assess the efficacy of a comprehensive list of technical bycatch mitigation measures for all major commercial fishing gears. We structured our review around the three stages of capture where opportunities exist to mitigate bycatch: preventing capture; increasing escape probability; and decreasing at-vessel/post...
Introduction Seagrass sediments are important ‘blue carbon’ reservoirs which store climatically significant quantities of organic carbon (C org ) at the global scale. Seagrass meadows that overly these sediments also provide a range of critical ecosystem services including shoreline stabilization, storm surge protection, and fisheries nursery grounds. However, the controls over accumulation and the sources of organic C to thes...
Horizontal genetic transfer (HGT) is a common phenomenon in eukaryotic genomes. However, the mechanisms by which HGT‐derived genes persist and integrate into other pathways remain unclear. This topic is of significant interest because, over time, the stressors that initially favoured the fixation of HGT may diminish or disappear. Despite this, the foreign genes may continue to exist if they become part of a broader stress resp...
Summary Peramine is a non‐ribosomal peptide‐derived pyrrolopyrazine (PPZ)‐containing molecule with anti‐insect properties. Peramine is known to be produced by fungi from genus Epichloë , which form mutualistic endophytic associations with cool‐season grass hosts. Peramine biosynthesis has been proposed to require only the two‐module non‐ribosomal peptide synthetase (NRPS) peramine synthetase (PerA), which is encoded by the 8.3...
Deficiencies in estimating the extinction date of the thylacine with mixed certainty dataNARA Subscribed
Article impact statement :Due to reporting biases, it is premature to conclude that thylacine extinction occurred soon after the last captive specimen died.
Phytoplankton primary production is at the base of the marine food web; changes in primary production have direct or indirect effects on higher trophic levels, from zooplankton organisms to marine mammals and seabirds. Here, we present a new time‐series on gross primary production in the North Sea, from 1988 to 2013, estimated using in situ measurements of chlorophyll and underwater light. This shows that recent decades have s...
