University Overview The University of Pennsylvania, the largest private employer in Philadelphia, is a world-renowned leader in education, research, and innovation. This historic, Ivy League school co...

The ecological and economic threat posed by invasive pests demands proactive mitigation. Species distribution models (SDMs) are widely used in efforts to predict where invasive species might spread af...

Telomeres are nucleoprotein structures that protect chromosome ends and are maintained by the Telomerase Reverse Transcriptase (TERT) protein that uses a noncoding Telomerase RNA (TR) as a template. I...

Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

Complete, haplotype-resolved genome assemblies have provided unprecedented insight into the evolution of structurally complex, rapidly evolving regions of human genomes; however, population-scale pang...

Biodiversity Postdoctoral Fellowship, 2-year (2026-2028) - 2 positions OPENAt UBC, we believe that attracting and sustaining a diverse workforce is key to the successful pursuit of excellence in resea...

The nature of standing genetic variation remains a central debate in population genetics, with differing perspectives on whether common variants are almost always neutral as suggested by neutral and n...

Summary · Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biod...

Understanding evolutionary repeatability is a central question in biology, as it informs how predictably organisms respond to similar selection pressures. However, the extent to which phenotypic repea...

One of the most devastating diseases finally has a treatment that could transform lives, tearful doctors tell BBC

New fruit fly research provides the first direct evidence of “dominance reversal,” revealing why pesticide resistance is so hard to eliminate in changing environments.

Measuring selection and dominance in fitness of the insecticide-resistant Ace alleles in Drosophila melanogaster, the authors show evidence for beneficial reversal of dominance, a mechanism that can s...

Your slides are not your talk.

Structurally complex regions of the genome are increasingly recognized as engines of evolutionary convergence due to their propensity to generate recurrent gene duplications that give rise to similar ...

How do new species arise? This is among the most fundamental questions in evolutionary biology. The first genetic model for how reproductive barriers …

Ecologists often leverage patterns observed across spatial climate gradients to predict the impacts of climate change (space-for-time substitution). We highlight evidence that this can be misleading n...
