Summary
This paleoenvironmental thesis is based on multi-parameter analyses of the fill of four lake systems (Vrana, Omišalj, Punta Secca and Osor) located in the heart of the Kvarner Archipelago (Croatia).
Geophysical and geochemical measurements of sediments (density, Susc. Magn., XRF, 15N, 13C...) are associated with the analysis of pollen grains and spores, non-pollen microfossils and microcharcoal. About sixty 14C dates, associated with the activity of radioelements, allow to build very solid age/depth models.
The evolution of the changes that have occurred over the last 30,000 years in the dynamics of each lake and its watersheds is then precisely described, since the introduction of the first agricultural practices. A succession of fluctuations in agrosystems can be highlighted during the Neolithic and Protohistory. Then, an important mutation affecting one of the lakes and its watershed is visible since about 3000 cal. BP. Hypotheses are then put forward to explain the historical and climatic changes of the local environment.
