In their most recent paper published in Systematic Biology, Phillip Mitteroecker, Michael L. Collyer and Dean C. Adams introduce a new system to measure phylogenetic signal in multivariate phenotypes. Phylogenetic signal is the tendency of closely related species to resemble each other more than distant ones. The authors approach a long-standing challenge in the statistical estimation of phylogenetic signal in mutivariate phenotypes, as phylogenetic signal until now have been mostly designed for univariate traits. However, biological traits are often multivariate, and univariate measures are therefore inadequate, and not meaningful on their own. The authors propose a novel method where the multivariate data is decomposed into linear combinations with the most or least phylogenetic signal, which is measured by Blomberg’s K. These components, called K-components, can be interpreted biologically, and scatterplots can show the data in a way that preserves phylogenetic signal. (Click on title to continue.)

Summer heralds conferences and workshops, and our KLI Fellows will be participating in many of them around the world. Let’s take a look at who’s is presenting what and where this summer! (watch this space for more as the list progresses…)
