Readers interested in using the original Pasoh 50-hectar plot data for purposes other than reviewing our analysis are advised to contact the <a href="https://www.frim.gov.my/" rel="nofollow">Forest Research Institute Malaysia (FRIM)</a> and the <a href="https://forestgeo.si.edu/" rel="nofollow">Center for Tropical Forest Science-Forest Global Earth Observatory (CTFS-Forest GEO)</a>, Smithsonian Tropical Research Institute. R codes employ 1-ha for subplot size and local species populations ≥ 10 trees per subplot for model parameter estimation (as baseline setting). One easily change subplot size and/or minimum tree density for local population selection.</p> <ul> <li> <p dir="auto"><strong>skt.r</strong> - Main R code for estimating species parameters and predicting a stable equilibrium solution in the competition model.</p> </li> <li> <p dir="auto"><strong>functions.r</strong> - R code defining some functions for calculating turnover rates.</p> </li> <li> <p dir="auto"><strong>data/pfr_sub_100by100.csv.gz</strong> - Processed subset of Pasoh 50-ha plot data, Peninsular Malaysia, for ca. 1990 and ca. 2000 censuses.</p> <ul> <li><code>species</code> - species ID, integer</li> <li><code>subplot</code> - subplot ID assigned by dividing the entire area into 100m x 100m, integer</li> <li><code>dbh1</code> - stem diameter (cm) in 1990, numeric</li> <li><code>dbh2</code> - stem diameter (cm) in 2000, numeric</li> <li><code>t</code> - inter-census duration (year), numeric</li> </ul> </li> </ul> <div dir="auto"> <h2>License</h2> <a href="https://github.com/kohyamat/skt#license"></a></div> <p dir="auto">The data files are licensed under the <a href="https://github.com/kohyamat/p-B/blob/main/LICENSE-CC-BY">Creative Commons Attribution 4.0 International License</a>, and the R codes are licensed under the <a href="https://github.com/kohyamat/skt/blob/main/LICENSE">MIT License</a>.</p>
