-------- Original Message -------- Subject: population divergence Date: Wed, 13 Apr 2011 09:57:44 -0400 From: johannes schied <[email protected]> To: [email protected] Dear all, I am want to test and quantify the similarity/disparity of populations of the same species in different habitats. The hypothesis is that certain habitats reinforce population divergence and certain do not. The plan is to sample two population of each habitat (~ 20 males, genitals structes will be used) and to do a procrustes analysis. Further on I would use the partial warp scores in a MANCOVA to test on significant differences between populations of the same habitat and use the formula for morphological disparity given in the book of Zelditch et al. 2004 (p. 297, 12.2.) to quantify morphological population divergence. So at the end I should have the values for population divergence for each habitat and should be able to conclude which habitat reinforce divergence of populations. My questions: (1) Is morphological disparity the proper procedure to quantify population divergence (intraspecific!)? (2) Is it right to use partial warp scores in a MANCOVA? (3) Do you have any suggestions to improve the design and analysis? Thanks a lot for your time & help, Johannes Schied Institute of Ecology University of Innsbruck
