Check out our new review paper on the ‘Analysis of Population Genomic Data from Hybrid Zones‘, which is now available on-line early from the Annual Review of Ecology, Evolution and Systematics.
This is a bit late, but several folks from the lab gave talks at the Evolution meeting in Portland this June. In case you missed them, here are links to video recordings on YouTube.
Samridhi Chaturvedi. The predictability of genomic changes underlying a recent host shift.
Amy Springer. Inbreeding depression in an ecological context.
Our paper on speciation in stick insects made the cover of Nature Ecology and Evolution (image by Moritz Muschick). In this paper we show how multiple factors come together for speciation to move from early to late stages of isolation and genomic differentiation, and we identify a distinct gap in genomic differentiation between con- and hetero-specific populations in sympatry.
You can read more about the paper in these blog and news articles:
We recently published a paper in Molecular Ecology Resources describing a method to determine ploidy in mixed ploidy samples from low to modest coverage GBS-like data (paper). This relies on both estimates of heterozygosity and allele specific read depth. The method we describe is implemented in the R package, gbs2ploidy. You can read more about it in this informative blog from the Molecular Ecologist.
Lauren’s paper on patterns and rates of gene flow within four narrowly endemic, spring-associated species is now out in Freshwater Biology. An image from the study of the amphipod Stygobromu made the cover (see above). The paper makes nice use of approximate Bayesian computation to contrast rates and models of gene flow among distantly related sympatric taxa.
Vladmir Nabokov is probably best known for his work in fiction (he wrote Lolita, among other things), but he was also a Lepidopterist. In fact, he was responsible for much of the early systematic work on the butterflies we study, Lycaeides. Lauren’s book (she contributed a chapter, Stephen Blackwell and Kurt Johnson were the editors) connects his work in art and literature to his science. Its out now (you can get it here)! Her chapter highlights how our own research has been influenced by Nabokov. Vladmir Lukhtanov wrote a nice review of the book for Nature.
Molecular Ecology published a special issue on detecting selection in natural populations. It included our paper, which introduced a new method for estimating selection from genetic time-series data (allele frequencies), along with interesting papers on detecting polygenic selection (Stephan 2016), promises of combing experimental evolution with population genomics (Bailey & Bataillon 2016), and considerations for conducting genome scans (Haasl & Payseur 2016) (along with many interesting empirical papers).
