Transect grassland trait data

Description

The package contains two real transects with data sampled in open sand grassland in Hungary (Bartha et al. 2008). These real transect data sets were from Bartha et al.’s (2008) long-term study on the effect of climate change on the interannual variability of grassland communities. The transect data sets represent: (1) the spatial pattern data of frequent species (species with more than 25 presences along the transect) selected as a threshold from standard textbooks; tran_grass_s), and (2) the spatial pattern data of plant functional types (PFTs) (in this case data of species which belong to the same functional groups were merged; tran_grass_t). These data represent the same transect and same community; however, for merging species, all data were used (i.e. the data of rare species were also considered within the particular PFT). For simplicity, we have only selected a 25m example with a very typical pattern; this extent (transect length) is already representative of the community pattern.

Usage

tran_grass_t

Format

A data frame with 713 species observations on the following two variables.

X

X coordinates

Species

Species. Note that for the Transect grassland trait data, 'Species' referes to plant functional type.

Details

The X refers to the sampling unit of the species in the sampling universe.
