in craniomandibular traits directly related to biting ability. Univariate and multivariate analyses of 12 craniomandibular traits showed that size is the primary axis of skull variation , whereas only a handful ...
precise local adaptation and extreme evolutionary diversification [26–29]. In mammals, several craniodental traits are associated with generating and sustaining maximal bite force. First , the incisor ...
trait size , and body size . In each PCA, PC1 explained the majority of variation in overall trait size (focal trait size : 53%; reference trait size : 44%; body size : 57%) and was used as an estimate ...
are generally well known, but the biomechanical relevance of this variation remains limited for some groups. By integrating geometric morphometric and biomechanical analyses, we test the hypothesis that skull ...
variation along the phylogeny, we used a node-by-node approach in the framework proposed by Gould & MacFadden (2004; see Giannini et al., 2012). For this purpose, body size information was incorporated ...
for all American marsupials, and Australidelphia for all the Australian forms plus Dromiciops and fossil microbiotheres (but see Hershkovitz 1992, 1995, 1999). Although all the information generated after ...
(< 5 kg) will average larger body size relative to mainland forms . A similar lack of support for ecogeographic rules has been noted in T. glis (Diard, 1820), suggesting that these “rules” are poor ...
and Jurassic non-mammalian cynodonts occupy the two smallest orders of vertebrate size magnitude, and it was not until the Cenozoic that the independent evolution of large body size began to characterize various ...
(Antoine et al. 2012). In terms of species diversity, occupied habitats, locomotor modes, and range of body sizes , caviomorph rodents are one of the most diverse mammalian clades (Ojeda et al. 2016 ...
to anterolaterally oriented ridge (‘vri’ in Fig 3) separates the anterior body from the parietal wing. The ridge arches slightly posterolaterally and continues anteriorly to form part of the lateral margin ...
