Lake ecosystem dynamics and links to climate change inferred from a stable isotope and organic palaeorecord from a mountain lake in southwestern China (ca. 22.6–10.5 cal ka BP)
Lake ecosystem dynamics and links to climate change inferred from a stable isotope and organic palaeorecord from a mountain lake in southwestern China (ca. 22.6–10.5 cal ka BP)
A detailed understanding of long-term climatic and environmental change in southwestern China is hampered
by a lack of long-term regional palaeorecords. Organic analysis (%TOC, %TN, C/N ratios and ?13C values)
of a sediment sequence from Lake Shudu, Yunnan Province (ca. 22.6–10.5 cal ka BP) indicates generally low
aquatic palaeoproductivity rates overmillennial timescales in response to cold, dry climatic conditions. However,
the record is punctuated by two marked phases of increased aquatic productivity from ca. 17.7 to 17.1 cal ka BP
and fromca. 11.9 to 10.5 cal ka BP.We hypothesise that these shifts reflect a marked, stepwise lacustrine response
to Asian summer monsoon strengthening during the last deglaciation.

Abstract
A detailed understanding of long-term climatic and environmental change in southwestern China is hampered
by a lack of long-term regional palaeorecords. Organic analysis (%TOC, %TN, C/N ratios and ?13C values)
of a sediment sequence from Lake Shudu, Yunnan Province (ca. 22.6–10.5 cal ka BP) indicates generally low
aquatic palaeoproductivity rates overmillennial timescales in response to cold, dry climatic conditions. However,
the record is punctuated by two marked phases of increased aquatic productivity from ca. 17.7 to 17.1 cal ka BP
and fromca. 11.9 to 10.5 cal ka BP.We hypothesise that these shifts reflect a marked, stepwise lacustrine response
to Asian summer monsoon strengthening during the last deglaciation.
