Postnatal dispersion of the Barn Owl (Tyto alba): monitoring breeding success; increase of nest sites availability (installation of nest boxes); factors influencing postnatal dispersion.

Predatory interactions among top predators–intraguild predation and superpredation: key factors in superpredation; the influence of the predatory risk in the intraguild preys behaviour; consequences for superpredators consumption of mesopredators.

Ecotoxicology in top predators: bio-magnification of heavy metals in birds of prey; the influence of food habits in mercury bio-magnification process.

Road effects in owls: mortality key factors; effects of roads in bird abundances; the role of roads in landscape fragmentation; the influence of roads in habitat selection and connectivity.
