Genomic Insights into Neutral and Adaptive Variation in Sage-Grouse: Implications for Ecology and Conservation

Identifying and preserving unique genetic adaptations is an important consideration for conservation and management strategies, particularly for species with geographic distributions that span diverse ecological conditions. Contemporary sequencing technology has now made it possible to probe the genome for potential genetic adaptations with unprecedented resolution in species of conservation concern. We recently completed sequencing the genomes of both Gunnison Sage-grouse (Centrocercus minimus) and Greater Sage-grouse (C. urophasianus). We are leveraging these new genomic resources to investigate differentiation of satellite populations, as well as metabolic adaptations to different types of sagebrush diets within and among both sage-grouse species. Using whole-genome resequencing from birds sampled across the West, we have identified several promising candidate genes underlying sage-grouse dietary adaptations. We also present results of whole-genome scans to examine regions within the genome with elevated divergence between populations and species. We discuss potential implications of these analyses for common management practices including translocation of birds, and sagebrush restoration efforts.
