Overview

Randomized trial reconstructs vegetation dynamics and climate variability in a high-altitude pond, suggesting significant environmental changes.

Key Points

  • This study aims to reconstruct past vegetation dynamics, fire regimes, and hydroclimatic conditions at a high-altitude pond in central Mexico over the Holocene.
  • Multiproxy analysis of pollen, diatoms, cladocerans, and other proxies
  • Characterization of three environmental change stages over the last 8.4 ka
  • Identification of drought events at ~3.2–2.7 ka, ~2.0–1.9 ka, and ~1.2–1.1 ka
  • The first stage (8.4–6.6 ka) showed a wetland environment with low fire activity.
  • The second stage (6.6–4.7 ka) saw increased montane forests and enhanced fire activity with a significant rise in planktonic diatoms.
  • The last stage (4.2 ka to present) presented fluctuating water levels and complex ecosystem dynamics influenced by identified drought events.
