Abstract: Populations that breed along steep elevation gradients show diverse physiological and morphological changes in response to the different environmental conditions. The latter has been discussed by Bergmann’s and Allen’s ecogeographic rules about body and appendage sizes and environmental temperature. We compared morphometric measures (mass, bill width, tarsus, wing, and tail length) of a Zonotrichia capensis population in two localities at different elevations with similar latitudes and photoperiods on the west… Show more

“…tarsus and culmen) in cooler climates in order to minimize heat loss [ 15 ]. However, other factors have also been suggested to influence phenotypic variation; for instance, longer wings and tails have been positively associated with higher elevations where low atmospheric pressures and strong air currents prevail [ 16 18 ], which helps to increase flight efficiency, as well as contributing to balance and lift [ 19 , 20 ]. Moreover, environmental variables such as precipitation could impact habitat characteristics such as understory density and overall forest interior structure [ 21 ], which can influence tarsus, wing and tail morphology since these traits are respectively related to foraging, flight performance and maneuverability [ 22 24 ].…”
