Adaptive and maladaptive genetic diversity in small populations: Insights from the Brook Charr (Salvelinus fontinalis) case study
This study compares lake, river and anadromous brook charr populations to examine the accumulation of potentially beneficial or harmful genetic variants. It relates connectivity, diversity and evolutionary processes, without reducing the consequences of isolation to a single indicator.
- The question
- What role do demographic and selective processes play in the variants present in more or less connected populations?
- The approach
- Comparison of SNP markers in fish from 50 populations and annotation of the potential effects of variants.
- What the article brings
- Drift and selection both contribute to the patterns observed; lower diversity does not simply translate into more deleterious variants.
- The limits
- The effects of mutations are partly predicted by computation. The full text consulted is the preprint, earlier than the published article.
