Overview

Biostratigraphic analysis uncovers ecosystem responses to climatic and geological events on Iturup Island.

Key Points

  • The study aims to reconstruct the impact of climatic changes and natural catastrophes on biotic landscape components over the Holocene.
  • Conducted biostratigraphic studies through diatom and pollen analyses in a valley peat bog
  • Used Bayesian modeling based on radiocarbon dating for age determination of lahars
  • Analyzed tephra interlayers from nearby volcanic eruptions
  • Reconstructed climatic rhythms and their relationship with global and regional changes
  • Identified ages of lahars as approximately 6020 and 4170 cal yr BP
  • Detected damage to woody vegetation and loss of moss cover due to volcanic ashfalls
  • Established stages of bog ecosystem development, including phases of increased and decreased watering
  • Revealed connections between climatic events and solar activity affecting cyclogenesis in the Pacific region
