| Changes in body size over ontogeny may influence the ontogenetic development of long bones, and thus important to our understanding of variation in morphological, physiological, and life-history traits within species. In this study, we sample the entire measurements of the Japanese quail (Coturnix coturnix japonica) of individual skeletons, to investigate the ontogenetic allometry of limb bone proportions by Reduced Major Axis (RMA) regression. The ulna and humerus were both positively allometric in relation to body mass, with their proximal ends growth more rapidly than other regions. Hindlimb bones exhibited more than one allometric pattern. The tarsometatarsus was negative; the femur presented positive allometry, with the width and depth of the proximal... |

| Morphological work on the appendicular myology of birds forms the basis for comparative, functional and systematic studies, but our knowledge of the descriptive anatomy of birds is still very incomplete. The musculature of the wing muscles of the Golden Pheasant (Chrysolophus pictus), an endemic species of China, is studied in detail. All wing muscles are present as in other Galliformes. Myological characteristics including the absence of a deep layer of M. pectoralis pars thoracicus, well development of anterbrachial muscles, as well as the occurrence of a distinct fleshy slip from the proximal belly of M. biceps brachii, are suggested to be associated with its flapping flight. This paper is the prelude to functional analysis on muscle architecture in... |
