Modular chromosome rearrangements reveal parallel and nonparallel adaptation in a marine fish

Genomic architecture and standing variation can play a key role in ecological adaptation, and contribute to the predictability of evolution. In Atlantic cod (Gadus morhua), four large chromosomal rearrangements have been associated with ecological gradients and migratory behaviour in regional analyses. However, the degree of parallelism , the extent of independent inheritance, and functional distinctiveness of these rearrangements remains poorly understood. Here, we use a 12K single nucleotide polymorphism (SNP) array to demonstrate extensive individual...

Data from: Sex and occupation time influence niche space of a recovering keystone predator

Predators exert strong effects on ecological communities, particularly when they re-occupy areas after decades of extirpation. Within species, such effects can vary over time and by sex, and cascade across trophic levels. We used a space-for-time substitution to make foraging observations of sea otters (Enhydra lutris) across a gradient of re-occupation (1–30 yrs), and nMDS analysis to ask if 1) sea otter niche space varies as a function of occupation time, and 2) if niche...

Data from: Chromosome polymorphisms track trans‐Atlantic divergence and secondary contact in Atlantic salmon

Sarah J. Lehnert, Paul Bentzen, Tony Kess, Sigbjorn Lien, John B. Horne, Marie Clément & Ian R. Bradbury
Pleistocene glaciations drove repeated range contractions and expansions shaping contemporary intraspecific diversity. Atlantic salmon (Salmo salar) in the western and eastern Atlantic diverged >600,000 YBP, with the two lineages isolated in different southern refugia during glacial maxima, driving trans-Atlantic genomic and karyotypic divergence. Here, we investigate genomic consequences of glacial isolation and trans-Atlantic secondary contact using 108,870 single nucleotide polymorphisms (SNPs) genotyped in 80 North American and European populations. Throughout North America, we identified extensive...

Integrating climate adaptation and biodiversity conservation in the global ocean

The impacts of climate change and the socioecological challenges they present are ubiquitous and increasingly severe. Practical efforts to operationalize climate-responsive design and management in the global network of marine protected areas (MPAs) are required to ensure long-term effectiveness for safeguarding marine biodiversity and ecosystem services. Here, we review progress in integrating climate change adaptation into MPA design and management and provide eight recommendations to expedite this process. Climate-smart management objectives should become the default...

Data from: An approach to incorporating inferred connectivity of adult movement into marine protected area design with limited data

Sarah K. Friesen, Rebecca Martone, Emily Rubidge, Jacopo A. Baggio & Natalie Ban
Marine protected areas (MPAs) are important conservation tools that can support the resilience of marine ecosystems. Many countries, including Canada, have committed to protecting at least 10% of their marine areas under the Convention on Biological Diversity’s Aichi Target 11, which includes connectivity as a key aspect. Connectivity, the movement of individuals among habitats, can enhance population stability and resilience within and among MPAs. However, little is known about regional spatial patterns of marine ecological...
