Holocene vegetation patterns in southern Lithuania indicate astronomical forcing on the millennial and centennial time scales.

ABSTRACT: The Earth's biota originated and developed to its current complex state through interacting with multilevel physical forcing of our planet's climate and near and outer space phenomena. In the present study, we focus on the time scale of hundreds to thousands of years in the most recent time interval - the Holocene. Using a pollen paleocommunity dataset from southern Lithuania (Čepkeliai bog) and applying spectral analysis techniques, we tested this record for the presence of statistically significant cyclicities, which can be observed in past solar activity. The time series of non-metric multidimensional scaling (NMDS) scores, which in our case are assumed to reflect temperature variations, and Tsallis entropy-related community compositional diversity estimates q* revealed the presence of
