Assessing the Jarman-Bell Principle: Scaling of intake, digestibility, retention time and gut fill with body mass in mammalian herbivores.
Traditional explanations for herbivore niche differentiation along a BM gradient should not be based on allometries of digestive physiology, and differences in the scaling of wet gut contents and dry matter gut contents confirm a previous finding that the dry matter concentration of gut contents decreases with body mass.
The Gavialis–Tomistoma debate: the contribution of skull ontogenetic allometry and growth trajectories to the study of crocodylian relationships
Findings concur with a morphological hypothesis that places Gavialis separate from Brevirostres, and Tomistoma closer to other crocodylids, and provides an additional, and independent, data set to inform on this ongoing phylogenetic discussion.
Bergmann's rule in mammals: a cross-species interspecific pattern
It is shown, in a dataset comprising 3561 mammal species from 26 orders, that while there is no significant correlation between latitude and body mass using conventional methods, this correlation is highly significant when the phylogenetic structure of the dataset is accounted for, thus supporting Bergmann's claim that the rule only applies to closely related species.
The shape of the mandibular corpus in large fissiped carnivores: allometry, function and phylogeny
Large fissiped carnivores show extensive functional convergence in mandibular corpus shape although the evolutionary routes leading to such functional convergence are different.
Humeral epiphyseal shape in the felidae: The influence of phylogeny, allometry, and locomotion
The shape of the proximal and distal humeral epiphyses in extant species of the felids, based on two‐dimensional landmark configurations, is investigated, with marked differences in epiphyseal shape between felid lineages.
Inconstancy in predator/prey ratios in Quaternary large mammal communities of Italy, with an appraisal of mechanisms
The course of predator/prey ratio in communities of large Plio-Pleistocene mammals in Italy is studied to suggest that this stepwise dynamic in PPR indicates changes in ecosystem functioning.
The impact of large terrestrial carnivores on Pleistocene ecosystems
It is argued that Pleistocene carnivores had the capacity to, and likely did, limit megaherbivore population sizes and that young proboscideans at their most vulnerable age fall within the predicted prey size ranges of many of the Pleiades large carnivores.
Bite of the cats: relationships between functional integration and mechanical performance as revealed by mandible geometry.
There is significant correlation between integration at the clade level and per-clade averaged stress values, on both original data and by partialling out interclade allometry from shapes when calculating integration, which suggests a strong interaction between natural selection and the evolution of developmental and functional modules at theClade level.
Cats in the forest: predicting habitat adaptations from humerus morphometry in extant and fossil Felidae (Carnivora)
Abstract Mammalian carnivores are rarely incorporated in paleoenvironmental reconstructions, largely because of their rarity within the fossil record. However, multivariate statistical modeling can
Ecogeographical variation in skull shape of capuchin monkeys
Skull shape in capuchins is significantly related to both environment and skull size, and is significantly associated with shape differences between species.
