Our main interest relies on behavioral ecology, including defense mechanisms, social behavior, sexual selection, and especially parental care. The projects conducted in our laboratory integrate long-term empirical studies to experimental manipulations in order to answer questions on the evolution of behavior. Although our work covers a variety of arthropod taxa, most of our production is focused on Opiliones, a highly diversified order in terms of morphology and habits that includes approximately 6000 species widespread throughout the world.

     Harvestmen are particularly suitable for behavioral studies because individuals of many species are abundant and easy to observe and manipulate, both in the field and laboratory. The team is composed of a lead researcher, Dr. Glauco Machado, undergraduate and graduate students. Whenever possible, we collaborate with colleagues with expertise in relevant fields, such as genetics and population ecology, so as to address questions at multiple levels.
