Selective breeding for production traits has yielded relatively rapid successes with high-fecundity aquaculture species. Discovering the genetic changes associated selection is an important goal understanding adaptation and can also facilitate better predictions about likely fitness of selected strains if they escape farms. Here, we hypothesize domestication as a change induced by inadvertent in culture. Our premise that standardized culture protocols generate parallel effects across independent strains. Using eastern oyster model newly developed 600K SNP array, this study tested multiple lines compared their progenitor wild populations. A single contrast was made between pooled (1-17 generations culture) all samples combined. Population structure analysis indicated rank order levels differentiation [wild - wild] < cultured] [cultured cultured]. genome scan to captive environment applied two methodologically distinct outlier tests versus strain identified total 1174 candidate SNPs.

ABSTRACT Local adaptation represents the balance of selection and gene flow. Increasingly, studies find that can occur on spatial scales much smaller than scale dispersal, resulting in balanced polymorphisms within populations. However, microgeographic might be facilitated or hindered by large‐scale environmental heterogeneity, such as across latitude. Marine systems present a special case, many marine species have high dispersal capacity so ‘neighbourhoods’ may encompass heterogeneity over both small large scales. Here, we leverage fine‐scale sampling California range Pacific purple sea urchin ( Strongylocentrotus purpuratus ), with previous evidence local extremely We despite complete absence neutral population structure, satellite‐based surface temperature tidal zone are associated subtle genetic differences among populations, suggesting lead to (latitudinal) (subtidal vs. intertidal) In fact, some same variants differentiate populations at scales, potentially because parameters related temperature. Further, genes expressed single tissue life history stage more divergent expected latitudinal comparisons, these specific functions generate phenotypic variation important for adaptation. Together, results suggest even little sorted varying complex mosaics.

Barnacle adhesive primarily composed proteins, but knowledge how proteome varies across tree life unknown due to lack genomic information. Here, we supplement previous mass spectrometry analyses barnacle with recently sequenced genomes compare proteomes Pollicipes pollicipes (Pedunculata) Amphibalanus amphitrite (Sessilia).

The interaction between selection and gene flow can determine to what degree populations are able adapt local environmental conditions. This presents a particular conundrum in marine systems, as many species have high dispersal capacity resulting nearly panmictic populations.

However we just beginning understand which variables might be strongest drivers functional outcomes genetic variants candidates for selection.
