Research interests

Behavioural and evolutionary biology with main focus on:

* Evolution and ecology of host-parasite interactions, with particular emphasis on parasite specialization.

I am interested in exploring this topic both from the host and the parasite’s point of view. I consider the proximate mechanisms regulating host-parasite interactions, like host health status and ecological factors such as host size and sociability. I also pay attention to relevant features of the natural history of the parasite that are noteworthy to understand host-parasite relationships (e.g. diapause and environmental factors that influence it). In cooperation with Dr. A. Barbosa I am studying the effect of climate change on parasite distribution and host-parasite relationships.

* Sexual selection, the evolution of secondary sexual characters and intersexual conflicts.

My main interests are:

- Evolution of secondary sexual characters on both male and females and mutual mate choice.

- The nest as a secondary sexual character.

- Intersexual conflict: mate and brood desertion, extra-pair paternity and related male and female strategies (paternity assurance strategies, manipulation of information, male coercive strategies such as aggresion and punishment).

- Influence of ecological factors on extra-pair paternity rates.

* Interspecific interactions and its implications for conservation.

I study the consequences of interspecific interactions in terms of conservation. Human activity (specially agricultural practices) is also considered in relation to its influence on diet, foraging behaviour and breeding biology of birds in agroecosystems and expansive and regressive processes of birds.
