I am interested in the evolutionary processes underlying phenotypic and life history trait variation in natural populations.

My main research line focuses on the causes of variation of individuals’ mating strategies -principally, extra pair paternity and social polygamy-, and the subsequent impact of these strategies on individual fitness. During my PhD, I also investigated the effect of individuals’ genetic diversity on fitness-related aspects such as survival or reproductive success.

Recently, I have started a set of studies focused on personality and behavioral plasticity. Behavioral traits are interesting because compared to morphological or life history traits are extremely flexible, being able to rapidly respond to sudden alterations  in  the environment.  Currently,  I am using collared flycatchers (Ficedula albicollis),  chimango caracaras (Milvago chimango) and bruchid beetles (Callosobrochus maculatus) as model species to shed light on questions such as whether individual differences in the components of behavior are heritable or related to fitness.

 

During my career, I have been also interested in conservation problems and thus, I have collaborated in projects investigating the effects of human activities in the demography and dynamics of wild populations.

Socio-ecological factors shape the opportunity for polygyny in a migratory songbird

Why females pair with already mated males and the mechanisms behind variation in such polygynous events within and across populations and years remain open questions. Here, we used a 19-year dataset from a pied flycatcher (Ficedula hypoleuca) population to investigate, through local networks of breeding pairs, the socio-ecological factors related to ...

Dispersers are not a random subset of the source population, and there is considerable evidence that they differ from non-dispersers in a number of phenotypic traits. However, it is not clear whether the magnitude and direction of these differences vary over time. Between 1988 and 2016, we investigated patterns of phenotype-dependent dispersal of pied ...
