We are delighted to share that our new paper has been published in Journal of Geophysical Research: Biogeosciences! Congratulations to all the authors and collaborators on this achievement.
Findings:
The southeastern Taiwan experienced wetter climates during 3800-2400 cal yr BP and 1600-800 cal yr BP. These periods were interspersed with drier climates between 2400-1600 cal yr BP and 800-0 cal yr BP.
Wetter periods were characterised by organic C loading, which showed different N cycles. Earlier periods were characterised by N-anaerobic loss pathways, whereas later wetter periods were largely dominated by nitrification.
These anoxic lake conditions along with high C loading pointed towards anthropogenic stress and suggested a hypothesis of humans reaching an altitude of 3500 meters above sea level; however, further fecal biomarker investigation is warranted.
