Large mobile genetic elements known as Starships act as vehicles for transferring transposable elements (TEs) between fungi. Here, Griem-Krey et al. show that these ‘hitchhiking’ TEs can drive rapid e...

Using a species-specific reference genome significantly improves the accuracy of population genetic analyses, as exemplified by mapping gray fox sequence data to genomes of several canid species. Mapp...

Traits that affect organismal fitness are often very genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature (...

Twenty years after the first publication that used the term microplastic, we review current understanding, refine definitions, and consider future prospects. Microplastics arise from multiple sources,...

Abstract. Methods for detecting gene flow between populations often rely on asymmetry in the average length of particular genealogical branches, with the A

Recent time-calibrated amphibian phylogenies agree on the family-level relationships among extant salamanders but had disparate sampling regimes and i…

Abstract. In many species, polymorphic genomic inversions underlie complex phenotypic polymorphisms and facilitate local adaptation in the face of gene flo

Interspecific hybrids tend to show a sex-specific reduction in fitness, thus limiting gene flow to loci inherited through the homogametic sex. Here, the authors identify a rare Y-chromosome introgress...

In evolutionary biology, we often think about the phylogeny of a group, the underlying relationships between the samples. When the comparison is of species (particularly those that are distantly relat...
