However, in other cases bottlenecks have likely reduced genetic diversity and may have restricted adaptation rates.
Additionally, sequencing mRNAs from specific tissues, developmental time points, or experimental conditions allows for rapid profiling of transcript abundance at a global scale [ 1] and analyzing phylogenetically restricted adaptations (e.g., social phenotypes in ants [ 10] and the capsaicinoid pathway in peppers [ 11]).
Overall, Rollie et al. show that selection by Cas1 plays an important role in restricting the adaptation process to particular DNA sites.
However, exclusion from their grazing areas is increasing pastoralists vulnerability to climate change, as it restricts their adaptation.
This pattern would be predicted if populations do not acclimate to the local thermal environment and high gene flow between populations restricts local adaptation to a thermal gradient.
On the unit level, extensive standardization and centralized decision-making restricts local adaptation.
These results indicate that loss of VDR restricts the adaptation to cholestasis and diminishes bile duct integrity in the setting of biliary-type liver injury.
Other factors will act to oppose or restrict local adaptation, in particular the level of gene flow between populations, plus genetic drift, environmental variability, and limited adaptive genetic variation (Gandon and Michalakis 2002; Laine et al. 2011).
The QTN programme can also clarify the role of aspects of genomic architecture chromosomal inversions, translocations, 'supergenes' in areas of suppressed or restricted recombination in adaptation (Kirkpatrick and Barton 2006; Scoville et al. 2009; Yeaman 2013).
Aitken (unpublished manuscript) found that geographically isolated populations of Sitka spruce are better adapted to their environments in terms of growth rate and phenology combined than peripheral populations from the continuous species range, suggesting that gene flow restricts local adaptation in the latter.
Restricting the basis adaptation to a specific subdomain affords finding a locally accurate solution.
