Coping with salt without salt glands: Osmoregulatory plasticity in three species of coastal songbirds (ovenbirds) of the genus Cinclodes (Passeriformes: Furnariidae)
(Springer Verlag, 2004)
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 ...
Breeding biology of the Thorn-tailed Rayadito (Furnariidae) in south-temperate rainforests of Chile
(COOPER ORNITHOLOGICAL SOC, 2005-02)
We conducted a study of the breeding biology of the Thorn-tailed Rayadito (Aphrastura spinicauda) in secondary forests on the continental island of Chiloe (42degreesS), southern Chile. Rayaditos are small insectivorous ...
Extrapair paternity in two populations of the socially monogamous Thorn-tailed Rayadito Aphrastura spinicauda (Passeriformes: Furnariidae)
(Wiley, 2020)
Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes: Furnariidae)
(2006)
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 ...
Seasonal changes in the use of marine food resources by Cinclodes nigrofumosus (furnariidae, aves): carbon isotopes and osmoregulatory physiology
(SOCIEDAD BIOLGIA CHILE, 2005-06)
Passerines lack functional salt glands and to a large extent avoid feeding on marine invertebrates. An exception is Cinclodes nigrofulnosits. Previous studies reported that the contents of its gastrointestinal tract had a ...
Coping with salt without salt glands: osmoregulatory plasticity in three species of coastal songbirds (ovenbirds) of the genus Cinclodes (Passeriformes : Furnariidae)
(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 ...
Phylogeography of a neotropical montane forest ovendird (premnoplex brunnescens; furnariidae): the influence of the complex topography and dynamic history of the andes on evolutionary differentiation
(UniandesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Biología, 2010)
The spatial and temporal aspects of Neotropical montane bird diversification are not well established. Here, we use a large sample of mitochondrial and nuclear DNA sequences to examine the effect of geographical barriers ...
