(ELSEVIER GMBH, 2010-08-28)The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific ...
-
(SPRINGER, 2004-07)We investigated the phenotypic plasticity of renal function in three South American coastal passerine Cinclodes (ovenbirds) differing in the proportion of marine prey they consume. Individuals were acclimated to two regimes ...

-
(Elsevier, 2009)The urine field osmolality in Zonotrichia capensis along a latitudinal gradient in rainfall and temperature in Chile was examined. We also investigated latitudinal variation in the renal traits that mediate how these birds ...

(Springer, 2014)Specific fatty acids (FA) such as unsaturated (UFA) and saturated (SFA) fatty acids contained in foods are key factors in the nutritional ecology of birds. By means of a field and experimental approach, we evaluated the ...
-
(OXFORD UNIV PRESS INC, 2010-08-06)Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is revealing the adaptive significance of personalities, although the mechanisms driving ...
-
Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...
-
(2006)Cinclodes nigrofumosus and C. oustaleti are two closely related songbirds that inhabit the northern Chilean coast during the austral fall and winter.This stretch spans a dramatic north to south latitudinal gradient in ...
-
(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 ...
-
(Frontiers Media, 2021)Understanding physiological traits and ecological conditions that influence a species reliance on metabolic water is critical to creating accurate physiological models that can assess their ability to adapt to environmental ...
-
(Universidad de Chile, 2023)El cambio climático y los riesgos antropogénicos alteran el ecosistema de las poblaciones naturales, por lo que es importante determinar la resiliencia de éstas ante tales amenazas. Se ha propuesto que la variabilidad ...
-
(2011)The climatic variability hypothesis (CVH) states that species are geographically more widespread at higher latitudes because individuals have a broader range of physiological tolerance or phenotypic flexibility as latitude ...
