GBE | Complex Patterns of Hitchhiking Mutation Load Among Stickleback Populations

Nickel, Laine & @andrewfoote.bsky.social studied whether adaptation in threespine sticklebacks is associated with a deleterious mutation load through hitchhiking, and find that hitchhiking mutation load patterns do not conform to model predictions.

(Top right) The logo for this project, which started with a crowdfunding effort to assemble a reference genome in collaboration with 10X Genomics. (Bottom) Using DNA and RNA data from six individuals (three males and three females), we investigated Gila monster sex chromosomes (ZW in females and ZZ in males) and their evolution, finding incomplete dosage balance between the sexes and a lack of dosage compensation.

The first draft of the Gila monster genome was used to study whether there is equal expression of genes on the Z chromosome between males (who have two Z chromosomes) and females (who have a single Z chromosome). academic.oup.com/gbe/article/... #2026MMM

Stephens, Kulczyk & @bhattacharyalab.bsky.social suggest that dark genes (those with no ascribable biological function) in stony corals originated via bursts of lineage-specific duplication, often from genes with known functions.

GBE remains committed to fair and inclusive publishing practices, including working to discourage parachute science—research conducted by external teams with little or no meaningful collaboration with local scientists, institutions, or communities.

The rapid decline of global biodiversity represents one of the most pressing challenges of our time, and evolutionary genomic research has a crucial role to play. With this collection, we call out to researchers working on conservation genomics to submit their newest research.
