SUMMARY

My research focuses on understanding mechanisms influencing food selection and intake in herbivores, in order to create more efficient alternatives for managing the production, health, and welfare of animals and the integrity and sustainability of the landscapes they inhabit. I am interested in principles that underlie foraging behavior with the aim of obtaining reliable knowledge on the plant species, parts, and chemicals an herbivore selects while grazing, as well as why, how, and when specific foods are ingested. More recently, my research has focused on exploring the ability of herbivores to self-select natural plant products and other protective substances to recuperate from illness and on taking innovative behavioral approaches aimed at reducing herbivores’ environmental impacts.
