Mario Melletti is an Italian freelance wildlife biologist and a member of the African Buffalo Initiative Group and the Wild Pig Specialist Group, both of the IUCN SSC. During his PhD and M.Sc. studies, he was affiliated with the Department of Animal and Human Biology, University of Rome "La Sapienza", Italy, and the Department of Conservation Biology, Estacion Biologica de Donana (CSIC-EBD), Seville, Spain. For about 3 years he has been studying the ecology and behavior of the forest buffalo in Central Africa. Mario has conducted research on other large mammals and has participated in some projects and surveys on large mammals in several African countries. In 2010, he began editing books on mammalian biology, conservation, and management. He has edited a total of seven books and about 70 scientific publications.

Rafael Reyna-Hurtado is a Mexican biologist who has been studying tropical ungulates in Mesoamerica since 1997. Rafael received his M.S. and Ph.D. degrees in Wildlife Ecology and Conservation from the University of Florida, USA. He also conducted a three-year postdoctoral study at McGill University, Montreal, Canada, focusing on East African terrestrial forest mammals. Rafael's research has focused on the movement ecology of social species, particularly the white-lipped peccary in the Calakmul forest of Mexico and the giant forest hog in Kibale National Park, Uganda. Rafael is a professor at El Colegio de la Frontera Sur in the city of Campeche, southern Mexico, where he has formed a team of highly qualified students who are conducting studies on the movement patterns of tropical ungulates throughout Mesoamerica. Rafael has published more than 100 scientific journal articles and book chapters, 20 of which focus on the ecological or population aspects of the Baird's tapir.
