Organismal performance abilities occupy a central position in phenotypic evolution; they are determined by suites of interacting lower‐level traits (e.g., morphology and physiology) and they are aExpand

Ecomorphological analysis of trophic niche partitioning in a tropical savannah bat community
The exceptional diversity of neotropical bat communities is sustained by an intricate partitioning of available resources among the member species. Trophical specialization is considered an importantExpand

Fight versus flight: physiological basis for temperature-dependent behavioral shifts in lizards
SUMMARY Previous studies have demonstrated that a behavioral shift from flight to aggressive behavior occurs at low temperatures in some lizards. Our data for the agamid lizard Trapelus pallidaExpand

Spatio-temporal gait characteristics of level and vertical locomotion in a ground-dwelling and a climbing gecko.
The effects of incline (vertical versus horizontal) on spatio-temporal gait characteristics (stride and step length, frequency, duty factor, degree of sprawling) were measured over a range of speedsExpand

Spatio-temporal gait characteristics of the hind-limb cycles during voluntary bipedal and quadrupedal walking in bonobos (Pan paniscus).
Spatio-temporal gait characteristics (step and stride length, stride frequency, duty factor) were determined for the hind-limb cycles of nine bonobos (Pan paniscus) walking quadrupedally andExpand

Rapid large-scale evolutionary divergence in morphology and performance associated with exploitation of a different dietary resource
Although rapid adaptive changes in morphology on ecological time scales are now well documented in natural populations, the effects of such changes on whole-organism performance capacity and theExpand

Bipedalism in lizards: whole-body modelling reveals a possible spandrel.
This paper illustrates how simple mechanical models based on morphological, ethological, ecological and phylogenetic data can add to discussions in evolutionary biology. Bipedal locomotion hasExpand

Abstract Morphological and physiological considerations suggest that sprinting ability and endurance capacity put conflicting demands on the design of an animal's locomotor apparatus and thereforeExpand

Omnivory in lacertid lizards: adaptive evolution or constraint?
Feeding specializations such as herbivory are an often cited example of convergent and adaptive evolution. However, some groups such as lizards appear constrained in the evolution of morphologicalExpand

Convexity Preserving Interpolatory Subdivision Schemes
Abstract. We construct local subdivision schemes that interpolate functional univariate data and that preserve convexity. The resulting limit function of these schemes is continuous and convex forExpand
