Main Research Interests

My main research line has focused on the behaviour, ecology and conservation of scavengers and how the presence of carcasses in the wild shapes other components of the ecosystem. I have been especially interested on the ecological implications of the predictability of carrion resources. During the last years of studying this fascinating system I have progressively interested on the ecosystem services that avian scavengers may provide. While these species are charismatic and offer both cultural and ecosystem services (ecotourism and fast elimination of carcasses) they also have to face the progressive abandon of traditional agro-grazing practices (main food source). Currently, I am involved in the study of how the abandonment of farmland areas can be considered as a key opportunity for restoring past biodiversity (rewilding). I am particularly interested in how to reconcile the conservation of charismatic endangered species but also sensitive to human presence (e.g. long-lived birds of prey) with cultural ecosystem services of rewilded farmlands.
