Comparative Phylogenetic Methods
Honestly, the only thing I read this week were the well written tutorials for the Bodega Bay Phylogenetics Workshop. If you’re interested in getting started with tree building, divergence date estimation, model selection, and evolution of discrete and continuous traits check out the tutorials. Complementary resource include: BEAST Google Group and R Phylo Wiki.
This open access article discuss the results of a study of human telomere shortening related to varying to lifestyle. The study sampled the same people 10 years apart and found shortening of telomeres at the second sampling point, but not related to some lifestyle factors. Measuring telomere length is of high interest as a non-invasive way to determine age of wildlife; however, accurate estimation remains elusive and requires baseline studies similar to this paper.
