Article
Paulo E. Llambías, Auteur ; María M. Jefferies, Auteur ; Agustín Zarco, Auteur ; Paula S. Garrido, Auteur ; Ramiro S. Arrieta, AuteurSeveral hypotheses propose an adaptive function of non-breeding nests (female attraction, decoys for nest predators and safe places for roosting). Alternatively, non-breeding nests may be structures abandoned before completion. Grass Wrens Cisto[...]
Article
Paula S. Garrido Coria, Auteur ; Drew Rendall, Auteur ; Rosario Panasiti Ros, Auteur ; Natalia C. García, Auteur ; Paulo E. Llambías, AuteurStudies of geographic variation in bird song can provide important insights into vocal evolution. An intraspecific approach, focused on a single species with a broad distribution, can be particularly helpful in understanding the diverse selectiv[...]
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[...]
Article
Ednei B. dos Santos, Auteur ; Paulo E. Llambías, Auteur ; Drew Rendall, AuteurTheory proposes an adaptive relationship between male song complexity, including large song repertoires, and improved breeding success. Evidence supporting these relationships exists but is sometimes mixed or weak. Here we provide a first compre[...]
Article
Paulo E. Llambías, Auteur ; Paula S. Garrido, Auteur ; María M. Jefferies, Auteur ; Gustavo J. Fernández, AuteurThe study of geographic variation of social mating systems can shed new light on our understanding of how ecological variables shape extant mating associations. We report data on the social mating system, parental care and life history traits of[...]
Article
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[...]
Article
Ednei B. dos Santos, Auteur ; Paulo E. Llambías, Auteur ; Drew Rendall, AuteurStudies of birdsong across very broad geographic scales, such as between the north temperate zone and the tropics, provide special opportunities to understand the role of variable ecologies, life histories and mating pressures on song structure [...]
Article
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[...]

Article
Paulo E. Llambías, Auteur ; Gustavo J. Fernández, AuteurNestboxes are known to increase clutch size, enhance breeding success and affect the social mating system of several cavity nesters. Although in recent years various cavity nesters have been studied in nestboxes in South America, the effects of [...]
Article
Paulo E. Llambías, Auteur ; Peter Wrege, Auteur ; David W. Winkler, AuteurWe studied the relationship among re-mating, site fidelity and breeding performance in the tree swallow Tachycineta bicolor using 16 y of data on reproductive biology in a population breeding in nest boxes near Ithaca, New York. Of 217 pairs for[...]
Article
I designed two experiments to evaluate how polygyny is achieved in Southern House Wrens (Troglodytes aedon inusculus) breeding in a south-temperate population. In the first experiment, I manipulated territory attractiveness by adding high qualit[...]
