My thesis is part of the PREREAL project, which aims to study fire activities in the boreal regions. I study sedimentary sequences sampled in lakes in Russia (Karelia) and Finland (Kainuu and Lapland). The analysis of charcoals, dendrochronology and assemblages of subfossil chironomids is used to relate the history of paleo-fire activities to climate changes. Ultimately, the objective is to understand how climate (temperatures and rainfalls) can influence the regime of fires.
