Takashi S. Kohyama, Matthew D. Potts, Tetsuo I. Kohyama, Kaoru Niiyama, Tze Leong Yao, Stuart J. Davies, & Douglas Sheil (2020) Trade-off between standing biomass and productivity in species-rich tropical forest: evidence, explanations and implications.

Contents

This dataset is a processed subset of the original dataset used in our analysis of biomass turnover across tree populations as demonstrated in the main paper. Readers interested in using the Pasoh 50-ha plot data for purposes other than reviewing our analysis are advised to contact the Forest Research Institute Malaysia (FRIM) and the Center for Tropical Forest Science-Forest Global Earth Observatory (CTFS-Forest GEO), Smithsonian Tropical Research Institute.

  • turnover_pfr.r - R code for calculating species-specific structural data and turnover rates.

  • data/pfr_observed.csv.gz - Pasoh 50-ha plot data, Peninsular Malaysia, for ca. 1990 and ca. 2000 censuses.

    • Cd - species code
    • x, y - coordinates (m) of stem location
    • dbh1 - stem diameter (cm) in 1990
    • dbh2 - stem diameter (cm) in 2000
    • t - inter-census duration (year)

  • data/pfr_identity_free.csv.gz - Pasoh 50-ha plot data (as pfr_observed.csv), where species identity and location are replaced between two stems with closest dbh1.
