Dear morphometricians,
I have a pretty big dataset of specimens for most species of pythons encompassing most of the size range for every species. I have been projecting the allometric trajectories and doing pairwise slope comparisons and things like that in Geomorph. However, it seems very obvious that the is a very strong phylogenetic signal in the data, as species within the same clade tend to have parallel trajectories. I have been trying to find a way to analyse this data in a phylogenetic framework, and so far I know there is no straightforward solution. I know in Adams and Nistri 2010 the trajectories where coded ad isometric and allometric and then reconstructed the ancestral states but the case it not so binary with my data. Would there be a way, for example, to extract a value for the slope and do an ancestral state reconstruction on that? Also, is there a way to incorporate phylogeny in slope comparison models? Any help would be greatly appreciated Damien Esquerré PhD Student, Keogh Lab Division of Evolution, Ecology and Genetics, Research School of Biology The Australian National University 44 Daley Road, ACTON ACT 2601, Australia -- MORPHMET may be accessed via its webpage at http://www.morphometrics.org --- You received this message because you are subscribed to the Google Groups "MORPHMET" group.
