title: Data from: Distribution patterns of lianas from subtropical to subboreal zones of the Japanese archipelago and the difference between climbing types

description: <strong>README</strong> This dataset was used for the statistical analyses in the article: Kusakabe et al. (2023) Basic Appl. Ecol. <strong>Sub_plot_data_v2.csv</strong> Liana abundances, environmental factors, and site information for each subplot in 19 study sites in the Japanese archipelago. Subplots are 400 m<sup>2</sup>(20 m × 20 m) quadrats. <strong>site_information</strong> <code>site_name</code> - Site_name. <code>site_code</code> - Site_code. <code>plot_code</code> - Subplot_code. <code>longitude</code> - Longitude of each plot (°E). <code>latitude</code> - Latitude of each plot (°N). <code>altitude</code> - Altitude of each plot (m). <code>forest_type</code> - Plots were classified into four types based on the composition of evergreen broadleaf, deciduous broadleaf, and evergreen coniferous trees. EC: evergreen coniferous forest, BC: mixed coniferous–broadleaf forest, BD: deciduous broadleaf forest, BE: evergreen broadleaf forest. The detailed definition of the forest type was described in Ishihara et al. (2011). <code>forest_status</code> - Plots were also classified into three categories based on the age of the forests. old growth: ≥ 150 years old, old secondary: ≥ 100 years old, secondary: &lt; 100 years old. The detailed definition of the forest status was described in Ishihara et al. (2011). <code>x, y</code> - Coordinates of the point of origin of each subplot in the census plots (m).<br> <strong>liana_stem_density & liana_basal_area</strong><br> Sum of liana stems (400 m<sup>-2</sup>) and basal area (cm<sup>2</sup>・400m<sup>-2</sup>) in each subplot. <code>whole</code> - All lianas. <code>twining</code> - Twining climbers. <code>root</code> - Root climbers. <code>tendril</code> - Tendril climbers. <code>hook</code> - Hook climbers. <code>scrambling</code> - Scrambling climbers.<br> <strong>environmental_factors</strong><br> Environmental factors used in the analyses. <code>MAT</code> - Mean annual temperature (°C). <code>MAP</code> - Mean annual precipitation (mm). <code>MSD</code> - Maximum snow depth (cm). <code>SOCN</code> - Soil organic layer carbon:nitrogen ratio. <code>SODM</code> - Soil organic matter dry mass (g・100 cm<sup>-2</sup>). <code>TSD</code> - Tree stem density with a diameter of ≥ 5 cm at breast height (400 m<sup>-2</sup>). <code>TBA</code> - Total basal area of trees with a diameter of ≥ 5 cm at breast height (cm<sup>2</sup>・400 m<sup>-2</sup>). Values of latitude, longitude, altitude, SOCN, SODM, TSD, and TBA were derived from published articles (Ishihara et al. 2011, Niwa et al. 2016) and associated, updated datasets that are available on the website of the Biodiversity Center of Japan (https://www.biodic.go.jp/moni1000/findings/data/index.html). The definitions of forest type and status follow Ishihara et al. (2011). Values of MAT, MAP and MSD were derived from the Agro-Meteorological Grid Square Data, National Agriculture and Food Research Organization (Ohno et al. 2016). <strong>References</strong> Ishihara, M.
