Connectivity matrices for seven benthic species

These are connectivity matrices calculated from the results of Lagrangian models (GITM forced with GETM) for the period 2001-2010 and for seven benthic species: Alcyonium digitatum, Echinus esculentus, Lophelia pertusa, Metridium senile var. dianthus, Porifera, Mythilus edulis and Crepidula fornicata. The paper describing the calculation of these matrices and the analysis can be found in: https://www.nature.com/articles/s41598-018-32912-2.The data were produced by analysing the results of the Lagrangian model GITM. The connectivity was calculated between the sectors...

Data from: Projected impacts of warming seas on commercially fished species at a biogeographic boundary of the European continental shelf

Katherine Maltby, Louise Rutterford, Jonathan Tinker, Martin Genner & Stephen Simpson
1. Projecting the future effects of climate change on marine fished populations can help prepare the fishing industry and management systems for resulting ecological, social and economic changes. Generating projections using multiple climate scenarios can provide valuable insights for fisheries stakeholders regarding uncertainty arising from future climate data. 2. Using a range of climate projections based on the Intergovernmental Panel on Climate Change A1B, RCP4.5 and RCP8.5 climate scenarios, we modelled abundance of eight commercially...

Data from: Disentangling structural genomic and behavioral barriers in a sea of connectivity

Julia M. I. Barth, David Villegas-Ríos, Carla Freitas, Even Moland, Bastiaan Star, Carl André, Halvor Knutsen, Ian Bradbury, Jan Dierking, Christoph Petereit, David Righton, Julian Metcalfe, Kjetill S. Jakobsen, Esben M. Olsen, Sissel Jentoft & Julia M.I. Barth
Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing effects of gene flow to allow for adaptation and speciation. Chromosomal inversions act as an important mechanism maintaining isolating barriers, yet their role in sympatric populations and divergence with gene flow is not entirely understood. Here, we revisit the question whether inversions play a role...

Consistent concentrations of critically endangered Balearic shearwaters in UK waters revealed by at-sea surveys

Jessica Ann Phillips, Alex N. Banks, Mark Bolton, Tom Brereton, Pierre Cazenave, Natasha Gillies, Oliver Padget, Jeroen Van Der Kooij, James Waggit & Tim Guilford
Aim: Europe’s only globally critically endangered seabird, the Balearic shearwater (Puffinus mauretanicus), is thought to have expanded its post-breeding range northwards into UK waters, though its distribution there is not yet well understood. This study aims to identify environmental factors associated with the species’ presence, and map the probability of presence of the species across the western English Channel and southern Celtic Sea, and estimate the number of individuals in this area. Location: The western...

Data from: Identification and characterization of Cyprinid Herpesvirus-3 (CyHV-3) encoded microRNAs

Owen H. Donohoe, Kathy Henshilwood, Keith Way, Roya Hakimjavadi, David M. Stone & Dermot Walls
MicroRNAs (miRNAs) are a class of small non-coding RNAs involved in post-transcriptional gene regulation. Some viruses encode their own miRNAs and these are increasingly being recognized as important modulators of viral and host gene expression. Cyprinid herpesvirus 3 (CyHV-3) is a highly pathogenic agent that causes acute mass mortalities in carp (Cyprinus carpio carpio) and koi (Cyprinus carpio koi) worldwide. Here, bioinformatic analyses of the CyHV-3 genome suggested the presence of non-conserved precursor miRNA (pre-miRNA)...

Data from: Quantifying physiological influences on otolith microchemistry

Anna M. Sturrock, Ewan Hunter, J. Andrew Milton, Edinburgh Ion Microprobe Facility, Rachel C. Johnson, Colin P. Waring & Clive N. Trueman
1. Trace element concentrations in fish earstones (“otoliths”) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor, and thus variations in otolith elemental chemistry primarily reflect changes in ambient water chemistry. 2. We carried out a long-term (1-yr) experiment, serially sampling seawater, blood plasma and otoliths of mature and immature European plaice (Pleuronectes platessa L.) to test...
