Dear all
I am currently analyzing a community dataset of two continuous traits survival and disease resistance. I ran two regressions: (1) considering each species independent data points, and (2) phylogenetic independent contrasts. Both regressions were significant. Blombergs K also significant and ~ 0.38, and 0.34, respectively. However, I am interested in the slope of these regressions. For regression 1, slope = 0.142, for regression 2 slope = 0.105. I am interested in saying how much (in %) the evolutionary relationships contributed to the slope. My question is: Can I say that evolutionary relationships accounted for 74% (0.105/0.142) of the observed slope? Or is it only 26%? Thanks in advance for your help, since I don't have any experience running these types of analyses. Best regards, Ana [[alternative HTML version deleted]]
