This study shows that strong sexual selection reduces deleterious mutations and extinction risk in beetle populations without decreasing genetic diversity.

This study examines inbreeding depression in Seychelles warblers after a population bottleneck, finding a polygenic load reduces lifespan and offspring production by 17.9% and 15.1% per 10% inbreeding increase.

This study identifies genomic regions and candidate genes associated with dispersal behavior in Tribolium castaneum using artificial selection and genome-wide association analysis.

The paper uses genetic pedigree data from Seychelles warblers to assess how life-history traits predict individual genetic contributions 15 years later, finding that lifetime reproductive success is the strongest predictor.

The paper tests if genetic rescue disrupts local adaptation in Tribolium castaneum by introducing thermally adapted lines into inbred populations and measuring productivity changes.

The paper uses path analysis on Seychelles warbler data to examine factors influencing delayed offspring dispersal, finding territory quality and helper presence significantly affect dispersal decisions.

This study shows that genetic rescue effectiveness depends on rescuer sexual selection background, but its benefits decline over generations in Red Flour Beetle populations.
