Data from: A three-dimensional analysis of the morphological evolution and locomotor behaviour of the carnivoran hind limb

Alberto Martín-Serra, Borja Figueirido & Paul Palmqvist
Background: The shape of the appendicular bones in mammals usually reflects adaptations towards different locomotor abilities. However, other aspects such as body size and phylogeny also play an important role in shaping bone design. We used 3D landmark-based geometric morphometrics to analyse the shape of the hind limb bones (i.e., femur, tibia, and pelvic girdle bones) of living and extinct terrestrial carnivorans (Mammalia, Carnivora) to quantitatively investigate the influence of body size, phylogeny, and locomotor...

Data from: A three-dimensional computer simulation of feeding behaviour in red and giant pandas relates skull biomechanics with dietary niche partitioning

Borja Figueirido, Zhijie Jack Tseng, Francisco J. Serrano-Alarcón, Alberto Martín-Serra & Juan F. Pastor
The red (Ailurus fulgens) and giant (Ailuropoda melanoleuca) pandas are mammalian carnivores convergently adapted to a bamboo feeding diet. However, whereas Ailurus forage almost entirely on younger leaves, fruits and tender trunks, Ailuropoda rely more on trunks and stems. Such a difference in foraging mode is considered as strategy for resource partitioning where they are sympatric. Here we use FEA to test for mechanical differences and similarities in skull performance between Ailurus and Ailuropoda related...

Data from: Patterns of morphological integration in the appendicular skeleton of mammalian carnivores

Alberto Martín-Serra, Borja Figueirido, Juan Antonio Pérez-Claros & Paul Palmqvist
We investigated patterns of evolutionary integration in the appendicular skeleton of mammalian carnivores. The findings are discussed in relation to performance selection in terms of organismal function as a potential mechanism underlying integration. Interspecific shape covariation was quantified by 2B-PLS analysis of 3D landmark data within a phylogenetic context. Specifically, we compared pairs of anatomically connected bones (within-limbs) and pairs of both serially homologous and functional equivalent bones (between-limbs). The statistical results of all the...
