Pedro P. Olea is a Professor and researcher at the Centro de Investigación en Biodiversidad y Cambio Global (CIBC-UAM), Departamento de Ecología, Facultad de Ciencias, Universidad Autónoma de Madrid, Spain. His research focuses on understanding how global human activities, such as hunting, and livestock and crop farming, affect patterns and processes in species, communities and ecosystems at different spatial scales, and how to apply this knowledge in their management and conservation. His research findings have been published in the major ecology and conservation journals.

Patricia Mateo-Tomás  is a postdoctoral researcher at the Centre of Functional Ecology (CFE) at the University of Coimbra, Portugal and the Oviedo University, Spain. Her work focuses on the ecology and conservation of scavengers, especially vultures but also other facultative vertebrate scavengers, and their relationships with human activities, such as hunting and livestock rearing (including transhumance) that have developed in natural ecosystems. She is particularly committed to bridging the gap between scientific knowledge and wildlife management and conservation through close collaboration with private and public stakeholders.
