Multiple, coordinated goals and holistic actions are critical
We examine estimates of dispersal in a broad range marine species through an analysis published values, and evaluate how well these values represent global patterns comparison with correlates dispersal. Our indicates historical focus studies on low-dispersal/low-latitude species, we hypothesize that are not generally applicable representative patterns. Large-scale were examined using database such as planktonic larval duration (PLD, 318 species) genetic differentiation ( F ST , 246 species)....
Despite the enormous economic and ecological importance of marine organisms, spatial scales adaptation biocomplexity remain largely unknown. Yet, preservation local stocks that possess adaptive diversity is critical to long-term maintenance productive stable fisheries ecosystems. Here, we document genomic evidence range-wide differentiation in a broadcast spawning fish, Atlantic cod ( Gadus morhua ), using genome survey single nucleotide polymorphisms. Of 1641 gene-associated polymorphisms...
The deep ocean below 200 m water depth is the least observed, but largest habitat on our planet by volume and area. Over 150 years of exploration has revealed that this dynamic system provides critical climate regulation, houses a wealth energy, mineral, biological resources, represents vast repository diversity. A long history deep-ocean observation led to initial concept for Deep-Ocean Observing Strategy (DOOS), under auspices Global Ocean System (GOOS). Here we discuss scientific need...
Abstract The deep sea plays a critical role in global climate regulation through uptake and storage of heat carbon dioxide. However, this regulating service causes warming, acidification deoxygenation waters, leading to decreased food availability at the seafloor. These changes their projections are likely affect productivity, biodiversity distributions deep‐sea fauna, thereby compromising key ecosystem services. Understanding how change can lead shifts species is critically important...
Monitoring and assessment must underpin development of a new international agreement
As populations diverge, genomic regions associated with adaptation display elevated differentiation. These islands of adaptive divergence can inform conservation efforts in exploited species, by refining the delineation management units, and providing tools for more precise effective population monitoring successful assignment individuals products. We explored heterogeneity its impact on resolution spatial structure Atlantic cod, Gadus morhua, using genome wide expressed sequence derived...
Summary 1. Environmental variables are often used as indirect surrogates for mapping biodiversity because species survey data scant at regional scales, especially in the marine realm. However, environmental measured on arbitrary scales unlikely to have simple, direct relationships with biological patterns. Instead, may respond nonlinearly and interactions between variables. 2. To investigate role of environment driving patterns composition large regions, we collated multiple sets from...
Cryptic multispecies genetic structure reflects ocean climate and is associated with response to change.
Abstract Climate change manifestation in the ocean, through warming, oxygen loss, increasing acidification, and changing particulate organic carbon flux (one metric of altered food supply), is projected to affect most deep‐ocean ecosystems concomitantly with direct human disturbance. drivers will alter deep‐sea biodiversity associated ecosystem services, may interact disturbance from resource extraction activities or even climate geoengineering. We suggest that ensure effective management...
Understanding patterns of dispersal and connectivity among marine populations can directly inform fisheries conservation management. Advances in high-throughput sequencing offer new opportunities for estimating connectivity. We used restriction-site-associated DNA to examine realized the sea scallop Placopecten magellanicus, an economically important bivalve. Based on 245 individuals sampled rangewide at 12 locations from Newfoundland Mid-Atlantic Bight, we identified genotyped 7163 single...
