What we’re reading


As we head into the weekend, here are a few things we’ve noticed that might be worth your screen-time.

In the journals

Bell, G. 2013. The phylogenetic interpretation of biological surveys. Oikos. doi: 10.1111/j.1600-0706.2013.00405.x.

I describe a method of nested sister-group analysis for estimating ecological similarity based on landscape features or on co-distribution. The phylogeny is dissected into triplets, each comprising two sister taxa and their outgroup. For a triplet at any phylogenetic level, the similarity of sister groups with respect to some given character can be compared with their joint similarity to the outgroup to give a single test of similarity by descent.

Poisot, T., Péquin, B. & Gravel, D. 2013. High-throughput sequencing: A roadmap toward community ecology. Ecology and Evolution. doi: 10.1002/ece3.508.

Here, we showcase how HTS can be put in practice by revisiting classical questions pertaining to the distribution and dynamics of ecological diversity. In particular, we start from characterization of α-diversity, and scale up to the integration of species interactions in species distribution. Doing so, we highlight how these techniques can rapidly transform modern ecology by bringing new answers general ecologists are concerned about.

Linnen, C.R., Poh, Y.-P., Peterson, B.K., Barrett, R.D.H., Larson, J.G., Jensen, J.D., et al. 2013. Adaptive evolution of multiple traits through multiple mutations at a single gene. Science 339: 1312–1316. doi: 10.1126/science.1233213.

We identified distinct regions within the Agouti locus associated with each color trait and found that only haplotypes associated with light trait values have evidence of selection. Thus, local adaptation is the result of independent selection on many mutations within a single locus, each with a specific effect on an adaptive phenotype, thereby minimizing pleiotropic consequences.
