Number of dated and corrected charcoal fragments as a function of (a) 200-year age classes in the northeastern subtropical dry forest and (b) 1000-year age classes in the southeastern subtropical dry forest in Puerto Rico, USA. The radiocarbon ages of 20 charcoal samples from the northeastern subtropical dry forest were determined by AMS (Accelerator MassSpectrometry) in August and November 2016 at the Earth System Science Department, University of California, Irvine, USA; and the radiocarbon ages of 58 charcoal samples from the southeastern subtropical dry forest were determined by AMS in July and August 2015 at the Lawrence Livermore National Laboratory, California, USA
