From common gardens to candidate genes: exploring local adaptation to climate in red spruce

Thibaut Capblancq et al.

Summary: This study combines genomic methods and common gardens to investigate local adaptation in red spruce. It identifies environmental gradients and loci involved in climate adaptation and uncovers phenotypic evidence of local adaptation to climate.

Evolution of polygenic traits under global vs local adaptation

Sam Yeaman

Summary: Observations of alleles associated with complex traits should be interpreted in the context of evolutionary processes. Genetic architecture can significantly impact evolutionary outcomes and provide insights into how evolution works. Local adaptation can lead to concentrated genetic architectures enriched for alleles of larger effect, but evolution of such architectures may be limited by various factors.

Linking evolutionary potential to extinction risk: applications and future directions

Brenna R. Forester et al.

Summary: Extinction-risk assessments are crucial for prioritizing conservation action, but quantifying extinction risk, especially incorporating evolutionary potential, is challenging. Disregarding evolutionary potential can lead to inadequate resource allocation and recovery planning. Fortunately, proxies for evolutionary potential can be estimated from environmental, phenotypic, and genetic data.

Adaptive evolution in a conifer hybrid zone is driven by a mosaic of recently introgressed and background genetic variants

Mitra Menon et al.

Summary: The genetic architecture of adaptive evolution in a conifer hybrid zone was revealed, with introduced variants favored in freeze-related environments and background variants favored in water availability-related environments. The mosaic of allelic variants within conifer hybrid zones may provide greater resilience to ongoing and future environmental change.
