The evolution of jumping performance in anurans: morphological correlates and ecological implications
(Wiley-Blackwell, 2009-05-01)
We investigated the evolution of anuran locomotor performance and its morphological correlates as a function of habitat use and lifestyles. We reanalysed a subset of the data reported by Zug (Smithson. Contrib. Zool. 1978; ...

Reassessment of the postcranial anatomy of Prozostrodon brasiliensis and implications for postural evolution of non-mammaliaform cynodonts
(Society of Vertebrate Paleontology, 2018-10)
Postcranial anatomical studies on non-mammaliaform cynodonts are essential for understanding postural and locomotor advances in mammalian evolution and provide information about the transition from the sprawling posture ...
Locomotion in rodents and small carnivorans: Are they so different?
(Springer, 2020-08-04)
Rodents and carnivorans constitute two diverse clades with variable life habits. To analyze the common ecomorphological aspects of their limbs in relation to their different substrate uses, the shape of humerus and femur ...
