In addition to the references to papers by Hansen and Bartoszek, and by Ives, Midford and Garland, I would biasedly suggest this paper:
Felsenstein, J. 2008. Comparative methods with sampling error and within-species variation: contrasts revisited and revised. American Naturalist 171: 713-725. The method estimates the within-species phenotypic variation (which, when you are analysing species means is the relevamt "measurement error" and also includes actual measurement error) and corrects for it. The software announced there is not in R, but I believe that Liam Revell's phytools package can call our program.
