Frank E. Zachos is head of the Mammal Collection at the Natural History Museum Vienna, Austria, affiliated lecturer at the University of Vienna and affiliated professor at the Department of Genetics at the University of the Free State in Bloemfontein, South Africa. He studied biology, history of science and philosophy in Kiel and Jena, Germany, and received his PhD in zoology in 2005. In 2009, he completed his habilitation for zoology and evolutionary biology. His main research topics comprise the intraspecific biodiversity, phylogeography, population genetics and conservation of mammals and birds, with a particular focus on red deer and other ungulates. He also has a long-standing interest in species concepts and the species problem as well as other theoretical and philosophical issues in evolutionary biology and systematics. He is the editor-in-chief of the journal Mammalian Biology and the editor of the Mammalia series within the Handbook of Zoology.
Luca Corlatti is a post-doctoral researcher in the field of animal behavioural ecology. After fieldwork experiences in Italy, Denmark and Sweden, he graduated in Environmental Sciences at the University of Padua (Italy) in 2006 with a thesis on ungulate demography. In 2008 and 2009 he has worked as a research assistant at the Institute of Wildlife Biology and Game Management in Vienna, Austria. Between 2009 and 2013, as a PhD fellow in Evolutionary Biology (Zoology) at Siena University, Italy (supervised by Prof. Sandro Lovari and Dr. Bruno Bassano), he has primarily focussed on the evolution of ungulate mating systems, specifically on the mechanisms underlying the maintenance of alternative tactics in a population of Alpine chamois in the Italian Alps. This interest has led to him to the project he has designed on the influence of anthropogenic effects on mating systems of mountain ungulates. He is also interested in other aspects of animal bio-ecology, such as population dynamics, spatial movements and abundance estimation.
