We are pleased to recognize two Honorable Mentions for the SSE Presidents’ Award this year: Skylar Berardi and Miles Roberts for their papers in Evolution Letters! shorturl.at/CpcoY @evolletters.bsky.social

Text: Society for the Study of Evolution, SSE Presidents' Award Honorable Mentions: Skylar Berardi, Drosophila melanogaster pigmentation demonstrates adaptive phenotypic parallelism over multiple spatiotemporal scales, Miles Roberts, k-mer-based diversity scales with population size proxies more than nucleotide diversity in a meta-analysis of 98 plant species.

Thrilled to finally share the magnum opus of my PhD that focuses on the genetic basis of evolutionary change! Specifically, we know we can map the genetic basis of a trait, but can we tell which genes will underlie the trait shift when it evolves? doi.org/10.1101/2025...

High-resolution mapping of a rapidly evolving complex trait reveals genotype-phenotype stability and an unpredictable genetic architecture of adaptation

The extent to which adaptation can be predicted, particularly for traits with complex genetic bases, is unknown. Here, we leveraged a model complex trait, model species, and high-powered longitudinal ...

Check out our paper in Evolution Letters! We used D. melanogaster pigmentation as a focal trait to explore parallelism in phenotypic and genomic responses to environmental change - read more at the link below 👇

Figure showing the experimental overview as a graphic. Remaining alt text taken from the figure caption in the paper: (A) we sampled flies from six wild orchard populations ranging from Homestead, FL, to Lancaster, MA, and established isofemale lines in the laboratory. (B) We returned to a focal orchard in Media, PA, at early- and late-season timepoints and collected flies to capture evolutionary patterns following winter and summer conditions. (C) We then seeded outdoor mesocosms (N = 9) with an outbred population originating from early-season collections in Media, PA, and sampled flies at the end of summer (mid-season) and fall (late-season) to determine if seasonal patterns are recapitulated in experimental populations controlled for migration, drift, and cryptic population structure. (D) Across each wild or experimental context, we sampled flies, established lines in the lab, completed common garden treatment to remove environmental effects, and scored females for abdominal pigmentation. We also conducted pooled DNA sequencing on additional flies sampled from each population to map genomic patterns for candidate pigmentation SNPs.
