The frequency and importance of polyploidy in tropical rainforest tree radiations
New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Climate and hybridization shape stomatal trait evolution in Populus
New Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...
