Evaluación de estrés en Zonotrichia capensis a diferentes altitudes
(Universidad de Chile, 2012)
Differences in circulating corticosterone levels associated with elevation of breeding sites in Rufous-collared Sparrows Zonotrichia capensis
(Springer Science and Business Media Deutschland GmbH, 2020-12-03)
To facilitate breeding and any energetically costly activity, individuals of the same species can substantially vary their circulating corticosterone (CORT) levels to cope with local environmental conditions at different ...
Differences in circulating corticosterone levels associated with elevation of breeding sites in Rufous-collared Sparrows Zonotrichia capensis
(2020)
To facilitate breeding and any energetically costly activity, individuals of the same species can substantially vary their circulating corticosterone (CORT) levels to cope with local environmental conditions at different ...
Two new feather mite species of the family Analgidae (Acariformes: Analgoidea) from the Rufous-collared Sparrow Zonotrichia capensis (Muller, 1776) (Passeriformes: Passerellidae)
(Magnolia Press, 2018-08-21)
Two new feather mite species of the family Analgidae are described from the Rufous-collared Sparrow, Zonotrichia capensis (Muller, 1776) (Passeriformes: Passerellidae), from Brazil: Analges ticotico sp. nov. (Analginae) ...
Osmoregulatory responses to dietary protein and water intake in the granivorous Zonotrichia capensis (Passerine, Emberizidae)
(Sociedad de Biología de Chile, 2007)
Physiological and biochemical responses to dietary protein in the omnivore passerine Zonotrichia capensis (Emberizidae)
(ELSEVIER SCIENCE INC, 2004-02)
We studied the physiological, biochemical and morphological responses of the omnivore sparrow Zonotrichia capensis, a small opportunistic passerine from Central Chile acclimated to high- and low-protein diets. After 4 weeks ...
Metabolic enzymes in seasonally acclimatized and cold acclimated rufous-collared sparrow inhabiting a Chilean Mediterranean environment
(Chinese Academy of Sciences, 2014)
Due to the higher energy requirements of birds during winter, it is predicted that the activities of metabolic enzymes (e.g., citrate synthase, CS and cytochrome C oxidase, COX) should increase in tandem with increases in ...
Intraspecific basal metabolic rate varies with trophic level in rufous-collared sparrows
(2009)
One of the most controversial hypotheses that associate basal metabolic rate (BMR) with food habits and habitat productivity is the food habit hypothesis (FHH). Here we examined the relationship between BMR, diet, and ...
