Article
Mariana E. Carro, Auteur ; Paulo E. Llambías, Auteur ; Bettina Mahler, Auteur ; Gustavo J. Fernández, AuteurDispersal constitutes one of the main processes that shape population genetic structure and dynamics. Combining a capture-mark-resighting methodology and molecular genetics analyses, we studied the natal dispersal behaviour of House Wrens (Trogl[...]
Article
Gustavo J. Fernández, Auteur ; Mariana E. Carro, Auteur ; Paulo E. Llambías, AuteurStudies of variation in breeding parameters are often based on temporal analyses of a single population. However, to differentiate between the effects of regional and local factors, neighboring populations with limited interpopulational dispersa[...]

Mariana E. Carro, Auteur ; Paulo E. Llambías, Auteur ; Gustavo J. Fernández, AuteurBreeding dispersal is the movement of an individual between breeding attempts and is usually associated with the disruption of the social pair bond, although mates may disperse together as a social unit. In monogamous territorial species, the de[...]

Paulo E. Llambías, Auteur ; Mariana E. Carro, Auteur ; Gustavo J. Fernández, AuteurSouth temperate songbirds differ from north temperate species in life-history traits, having greater adult survival, smaller clutch size, longer developmental periods and extended parental care. Due to its broad distribution, the House Wren, Tro[...]

Fernández, AuteurSeasonal fecundity of birds is influenced by clutch sizes and the number of successful breeding attempts during a breeding season. As such, understanding the factors that determine the decision to initiate multiple broods within a season and the[...]
