Climate warming weakens local adaptation

The paper quantifies how climate change impacts population performance by analyzing temperature and precipitation effects, finding that local adaptation to temperature is critical and deviations reduce performance.

Variation in adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion

This study uses transplant data to show that populations at geographic range edges have varying adaptation levels, with poleward edges showing lower fitness and equatorial edges showing higher fitness relative to foreign populations.

Geographic variation in reproductive assurance of Clarkia pulchella

The paper investigates geographic and climatic factors influencing reproductive assurance in Clarkia pulchella by manipulating pollinator access across eight sites.

Biotic interactions affect fitness across latitudes, but only drive local adaptation in the tropics

The paper examines how biotic interactions influence local adaptation across latitudes, finding they affect fitness but only strongly drive adaptation in tropical regions.

Gene flow improves fitness at a range edge under climate change

This study shows gene flow from warmer populations improves fitness at a species range edge under climate change, with benefits both from climate adaptation and reduced homozygosity.
