[MORPHMET] Microscribe Digitizers - 6th degree of motion

2015-09-16 Thread Katrina Jones
Dear Morphometricians, Does anyone have opinions on Microscribe digitizers with 5 versus 6 degrees of freedom? We are getting a digitizer for the lab, and noticed that some styles have additional rotation of the stylus (6th degree of motion). Is this a useful feature? There seem to be attachable

[MORPHMET] new phylogenetic comparative method for shape data

2015-09-16 Thread Adams, Dean [EEOBS]
Colleagues, I wish to alert you to a new method John Denton and I just published in Evolution. The approach enables one to compare rates of phenotypic evolution between two or more multivariate traits in a phylogenetic context under Brownian motion. The method is described in our paper "A new
