Parallel adaptive evolution of Atlantic cod on both sides of the Atlantic Ocean in response to temperature
Despite the enormous economic and ecological importance of marine organisms, the spatial scales of adaptation and biocomplexity remain largely unknown. Yet, the preservation of local stocks that
Global patterns in marine dispersal estimates: the influence of geography, taxonomic category and life history
TLDR
Examination of estimates of dispersal in a broad range of marine species through an analysis of published values indicates a historical focus in dispersal studies on low-dispersal/low-latitude species, and it is hypothesized that these studies are not generally applicable and representative of global patterns.
Trans-oceanic genomic divergence of Atlantic cod ecotypes is associated with large inversions
TLDR
Overall, this work identifies several large genomic regions—each containing hundreds of genes—likely involved in the maintenance of genomic divergence in Atlantic cod on both sides of the Atlantic Ocean and suggests that migratory behaviour is derived from more stationary, ancestral ecotypes.
Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
TLDR
This work demonstrates the utility of genome scans for adaptive divergence in the delineation of stock structure, the traceability of individuals and products, and ultimately a role for population genomics in fisheries conservation.
Conservation genomics of anadromous Atlantic salmon across its North American range: outlier loci identify the same patterns of population structure as neutral loci
TLDR
The most comprehensive genetic and genomic database for Atlantic salmon to date is used, covering the entire North American range of the species, and neutral and putatively selected loci are used to integrate adaptive information in the definition of conservation units.
Identifying patterns of dispersal, connectivity and selection in the sea scallop, Placopecten magellanicus, using RADseq‐derived SNPs
TLDR
The hypothesis that limited effective dispersal structures scallop populations along eastern North America are supported, which can help refine the appropriate scale of management and conservation in this commercially valuable species.
megasat: automated inference of microsatellite genotypes from sequence data
TLDR
The results show that with appropriate selection of loci, automatedgenotyping of microsatellite loci can be achieved with very high throughput, low genotyping error and very low genotypes costs.
Applications of random forest feature selection for fine‐scale genetic population assignment
TLDR
A role for machine‐learning approaches in marker selection across large genomic data sets to improve assignment for management and conservation of exploited populations is demonstrated.
Otolith elemental composition and adult tagging reveal spawning site fidelity and estuarine dependency in rainbow smelt
TLDR
It is concluded that population structure in anadromous smelt is maintained by small-scale habitat associations limited to a single estuary, supporting a hypothesis of demographic isolation among estuaries.
