Speleothem growth intervals reflect New Zealand montane vegetation response to temperature change over the last glacial cycle
Abstract Flowstone speleothem growth beneath Mount Arthur, New Zealand shows a clear relationship to vegetation density and soil development on the surface above. Flowstone does not currently form beneath sub-alpine Nothofagus forest above ca. 1000–1100 m altitude but U-Th dating shows it has formed...
