Incorporating phenotype and genotype in model-based species delimitation

  Species are the fundamental unit of biology but identifying them is a challenging task that receives a lot of theoretical and empirical attention. In a recent Evolution paper, Solís‐Lemus et al. (2015) introduce a new model-based method that integrates phenotypic and genetic data … Continue reading

Species and sensibility

Pante et al. (2014) performed a literature review of marine population connectivity in order to illustrate the biased estimates of connectivity which can result from the failure to recognize an evolutionary-relevant unit, such as a species. When exploring the connectivity … Continue reading

The Evolution of Recombination

In a recent publication, Lesecque et al (2014). provide key evidence that fills in some of the blanks to an age old question – how do recombination hotspots evolve? Their analyses of major PRDM9 (a polymorphic zinc finger protein with … Continue reading

Identifying and quantifying fitness effects across loci

The following guest post by Ethan Jewett is cross-posted from the is cross-posted from the CEHG blog at Stanford. Enjoy! The degree to which similarities and differences among species are the result of natural selection, rather than genetic drift, is … Continue reading

For viruses, ecology shapes the speed of evolutionary change

Molecular ecologists are interested in understanding what patterns in genetic variation across and among populations can tell us about the ecology of the living things we study. But a paper published in the latest issue of The American Naturalist demonstrates … Continue reading

Want to share your code?

In this line of work, we have all encountered tasks that are tedious, time consuming, and repetitive.  (Or if not, maybe give it a bit more time.) When confronted with these situations, people tend to fall into one of two … Continue reading

Evolution 2013 Recap

As we all slowly trickle back from the recent SSE meeting in Snowbird, we’ll each be posting our own thoughts and summaries of the conference. I personally had a fantastic time, met a lot of great people, and saw a … Continue reading

Speciation with gene flow and the virtual beanbag: Genome-level effects increase divergence during ecological speciation, but linkage is not required

This post is a guest contribution by Dylan Goldade, Kathryn Theiss, and Chris Smith, from the Biology Department at Willamette University. See below for the coauthors’ afflilations and research interests. In a famous address given on the hundredth anniversary of the … Continue reading
