The Predictable Complexity of Evolutionary Allometry

Webplot.procD.allometry: Plot Function for geomorph Description The following are brief descriptions of the different plotting methods, with references. If "method=CAC" (the default) the function calculates the common allometric component of the shape data, which is an estimate of the average allometric trend within groups (Mitteroecker et al. 2004). WebEvolutionary allometry was quantified by regressing the shape coordinates on log(CS) using PGLS under a Brownian model using the function procD.pgls of geomorph. Allometry was tested by 10 000 permutations. We visualized the evolutionary allometry by deformation grids in the same way as for the ontogenetic allometry. how to use windows boot manager https://qbclasses.com

WebThis allometry is detected as β ≠ 1, where β is the slope of a model II regression of log (male size) on log (female size). Most frequently, β exceeds 1, indicating that SSD increases with size where males are the larger sex, but decreases with size where females are larger, a trend formalized as “Rensch's rule.”
