Roberto Cazzolla Gatti
Roberto Cazzolla Gatti (born February 11, 1984) is an Italian environmental and evolutionary biologist, and biodiversity researcher who studies the evolution and the ecology of life on Earth. He is an associate professor of Ecology and Biodiversity at the Tomsk State University. He also works as a freelance documentary photographer and wildlife filmmaker and coordinates geographic and scientific explorations of some of the most remote places on Earth.
He graduated in Biology (Bachelor’s Degree), defending a thesis in Marine Ecology and in Environmental and Evolutionary Biology (Master’s Degree, Hons) at the University of Bari, Italy, defending a thesis in Zoology and Anthropology (“Primate visual system and stereopsis”). He holds a Ph.D. in Forest Ecology earned at the University of Tuscia in Viterbo (Italy), studying the tropical forests of Africa and their biodiversity. He also holds a II Level Master’s Degree (Hons) in International Policies and Global Environmental Protection earned at the University of Tuscia, defending a thesis on “Africa: biodiversity and climate change”. He also received a diploma from the School of Specialization in “Biodiversity and Ecosystem Services” at the Potsdam Institute for Climate Impact Research (PIK), Germany with a training in Peyresq, Alpes de Haute-Provence, France. He served for many years as a scientific advisor for the World Wildlife Fund (WWF) Italy and the Food and Agriculture Organisation (FAO) of the United Nations (UN). He is a member of the CEM (Commission on Ecosystem Management), SSC (Species Survival Commission) and the WCPA (World Commission on Protected Areas) of the IUCN (The International Union for Conservation of Nature).
Besides conducting field research studies (he worked 5 years in the Mediterranean steppes and shrublands of southern Italy and the Balkans, 6 years in the tropical Africa, India, Indonesia and Australia, 3 years in Siberia), he is best known for arguing that biodiversity is an autocatalytic ecological and evolutionary process and for providing evidence of non-primate animal self-awareness (for instance, studying dog's cognition with a novel "Sniff-test" ).
He proposed that "life begets life" and that the diversity of species on Earth is generating itself.
He also suggested several innovative hypotheses and theories in ecology and evolution such as the endogenosymbiotic origin of biodiversity, the canopy height-biodiversity relationship (proposing the existence of a Species-Volume Relationship in ecology), the coexistence of species through the "avoidance of competition" , and the fractal nature of the latitudinal biodiversity gradient .
He strongly advocates against considering competition as the main driver of evolution and endorses a reconsideration of the importance of cooperative/mutualistic relationships to explain the existence of biological diversity. In 2011, he proposed the "Biodiversity-related Niches Differentiation Theory (BNDT)" in which he argued that the number of niches in an ecosystem depends on the number of species present in a particular moment and that the species themselves allow the enhancement of niches in terms of space and number. He found that using a three-dimensional model as an ecological hypervolume and testing the theory on different ecosystems it is possible to demonstrate that each species plays a fundamental role in facilitating the colonization by other species by simply modifying the environment and exponentially increasing the available niches. The BNDT stresses the evidence that the process of niche differentiation is strictly addressed by species. This approach has various consequences, first in the reconsideration of the patterns of species coexistence and second in terms of a better understanding of the actual importance of cooperation and competition in the evolution of biological diversity.
In 2013 he wrote the novel-essay "The paradox of civilization" (in Italian: "Il paradosso della civiltà"). The book is inspired by his journeys in tropical areas, the encounters with African Pygmies and the life in the wild and narrates the abuses of civilised societies over the environment and indigenous people.
