▪ Abstract We use a comparative approach to examine some of the physiological traits that
make flight possible. Comparisons of related fliers and runners suggest that fliers generally …

The evolution of flight is the most important feature of birds, and this ability has helped them
become one of the most successful groups of vertebrates. However, some species have …

Humans and birds use very different running styles. Unlike humans, birds adopt “grounded
running” at intermediate speeds—a running gait where at least one foot always maintains …

We developed a three-dimensional, biomechanical computer model of the 36 major pelvic
limb muscle groups in an ostrich (Struthio camelus) to investigate muscle function in this, the …

Long‐distance seed dispersal may have important consequences for species range,
migration rates, metapopulation dynamics, and gene flow. Plants have evolved various …

Physicochemical characteristics and oxidative stability during storage were determined in
Gastrocnemius pars interna (GN) and Iliofiburalis (IF) muscles of Rhea americana. Glycolytic …

The functional significance of the uncinate processes to the ventilatory mechanics of birds
was examined by combining analytical modeling with morphological techniques. A …

The volumetric method of 'convex hulling'has recently been put forward as a mass prediction
technique for fossil vertebrates. Convex hulling involves the calculation of minimum convex …

Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites
with some similar biomechanical characteristics to humans. Their growth rates are …

ABSTRACT Hindlimb segmental kinematics and stride characteristics are quantified in
several quail locomoting on a treadmill over a six‐fold increase in speed. These data are …
