Humans, selection, evolution and ecological timescales … a potent cocktail

It’s been awhile since I last was able to write for TME. But, finally, I’ve stolen away some time to write about a recent study in Ecology Letters that I couldn’t put down once I started reading it. Yes, it’s about mating … Continue reading

Still ruffling feathers after all these years: Darwin’s finches and a molecular view of adaptive radiation

One of the many lovely things about molecular ecology is its ability to shine new light on old stories. The well-known case of Darwin’s finches is a classic example of adaptive radiation. These finches demonstrate a clear instance where over time, … Continue reading

Conifer convergence

Convergent local adaptation is typically studied within a species or between closely related species. In these cases, it is perhaps not unexpected to observe parallel evolution due to common genetic variation, constraints, etc. Convergence between species is somewhat less studied, … Continue reading

Divergence and Linked Background Selection

We have widely discussed the reduction in neutral diversity due to demography and linked selection effects (e.g. selective sweeps and hitchhiking, or background selection) in several previous posts (e.g see here, here, and here). However, how linked selection affects neutral divergence … Continue reading

Building bridges across the chaos

In a new review, Eldon and co-authors (in press) attempt to build a bridge across the chaos of genetic patchiness in the sea. They i) describe the patterns characterized as chaotic genetic patchiness, ii) discuss the potential causes of these patterns and … Continue reading

The Genomics of Rapid Adaptation

Phenology (the timing of life cycle events such as growth, breeding, or migration) is among the most sensitive organismal traits to climate and environmental change. In recent years, phenological shifts have been documented in numerous taxa, in traits such as … Continue reading

New insight into the genetic basis of industrial melanism

The evolution of coloration in peppered moths during the industrial revolution is one of the most well known examples of natural selection in action. Part of the appeal of the system is the apparent simplicity. The once-abundant light colored morph … Continue reading
