Subtropical forest vegetation along elevation gradient in Taiwan: Lalashan transect

Source of data

Zelený, Li, Shen, Chen et al. (data collected within Vegetation Ecology Lab, NTU)

Description of the dataset

Vegetation plots (20 m x 20 m) with recorded all woody species with DBH > 1 cm and taller than 2 m. A set of leaf and wood traits have been sampled for most of the species recorded in the dataset (measurement was done three leaves per individual, and for each species we collected at least three individuals along the transect). Topography, soil, light, decomposition and microclimate data are also available.

Data for download

File name File type Description
lalashan.xlsx Excel file Contains species × sample matrix, environmental variables, explanation of species abbreviations and metadata
lalashan.RData r object file An R object, a list of three components, spe, env and traits
load (url ('https://raw.githubusercontent.com/zdealveindy/anadat-r/master/data/lalashan.RData'))
 

The lalashan object which will be loaded into the working space is a list with three components:

  • spe Compositional matrix of all woody species and their calculated IVI (sample x species, importance value index)
  • env Matrix of environmental variables (sample x env)
  • traits Matrix of species traits (species x traits); note that there are some missing values for some of the traits
