I gave a talk today on doing very basic phylogenetics in R, including getting sequence data, aligning sequence data, plotting trees, doing trait evolution stuff, etc. Please comment if you have code for doing bayesian phylogenetic inference in R. I know phyloch has function mrbayes, but can’t get it to work… Phylogenetics in R View more presentations from schamber

FigShare - I very much like this idea of a place to put your data online that is NOT published. Dryad is a nice place for datastes linked with published papers, but there isn’t really a place for datasets that perhaps did not make the cut for a published paper, and if known to the scientific community, could potentially help resolve the “file-drawer” effect in meta-analyses.
