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
