GBE | The Genomics of Convergent Adaptation to Intertidal Gravel Beaches in Mediterranean Clingfishes Endemic Mediterranean gravel beach clingfish (Gouania ssp.) in a dynamic gravel environment. Using an integrative genomic and morphological approach, this study investigates how similar body shapes repeatedly evolve and what this reveals about the genomic basis of phenotypic convergence.

Wagner et al. combined phenotypic and genomic data to study convergence in Mediterranean gravel beach clingfishes, revealing convergence at the level of individual genes, variants, and biological pathways, but not across genomes.

Genome Biology and Evolution | March 2026 cover Bacot et al. combined whole-genome pool-sequencing and RNA-sequencing to study insecticide resistance in the Asian tiger mosquito (Aedes albopictus) from La Réunion island. The map shows sampling locations in La Réunion. The heatmap indicates log-fold changes in gene expression of candidate genes over-transcribed in association with deltamethrin resistance.

The March cover of Genome Biology and Evolution features the study by Bacot et al. on the genetic mechanisms underlying the Asian tiger mosquito's adaptation to insecticides on the island of La Réunion.

Emergence and Tandem Repeat-Mediated Elongation of a Translated De Novo Open Reading Frame in Human Oncogenic RNA Gene VPS9D1-AS1 (MYU) Abstract. New protein-coding genes can arise de novo from ancestrally noncoding regions when open reading frames (ORFs) outside existing genes are exposed

Chou et al. reconstructed the evolutionary history of c16riboseqorf143 (orf143), one of the longest unannotated human translated ORFs. This study reveals stop codon disruption and TR array expansion as the mechanisms of orf143 elongation.
