The profound climatic changes and the need to identify solutions forthe survival of mankind represent major topics of debate in thecontemporary society. We must know that even since its beginnings, the modern mankind has been faced with climate changes some of them radical, which have left their mark on the strategies related tothe exploitation and the management of the environment, specifically the animal one, and have been reflected in the types of economic practices. By this project proposition, we shall try to analyse, quantifyand compare the effects of a nearly “purely climatic” phenomenon and the effects of a mostly human-driven process and to provide an integrated image on the ways in which the animal environment was exploited by the prehistoric communities, at the transition from hunter-gatherers to farmers-breeders (7.200 B.C. – 5.000 B.C.), identifying and comparing different eco-cultural models developed inthe northern Danube area. The investigations will cover two prioritydomains: of biodiversity evolution (e.g., taxonomic richness; magnitude of fauna turnover) and of correlative human societal transformations, especially in fauna management and techniques of exploitation. Among others, the objectives of our project include the identification of the modifications intervened in the relation between the domain covered by this project and the way in which it has beenreflected in the paleo-economy, habitat, social or spiritual organization.
