Interpretation of climate change and deglaciation events from palaeovarves requires a complete understanding of varve composition, depositional environments and the non-climatic events that may influence varve thickness record. We examined a Baltic Ice Lake varve-thickness chronology from western Estonia, eastern Baltic Sea, composed of 26 individual varve series and spanning 584 years of Late Weichselian deglaciation. The direction (azimuth) to the increasing seasonal layer thickness and correlation between the w...

Phenology is a study of timing of event taking place in nature. In a functional ecosystem phenological phases for mutually dependent are synchronized. In a rapidly changing climate there is a risk of decoupling, that is spring development of interdependent could species proceed at different peace. We are investigating the likely timing of spring phenological phases during the last and upcoming centuries for two tree species common in northern and central Europe: bird cherry (Prunus padus known also as Padus racemo...
