Plant traits response to grazing

Description

Plant species cover, traits and environmental parameters recorded around livestock watering points in different habitats of central Namibian farmlands. See the Wesuls et al. (2012) paper for a full description of the data set.

Usage

data(piosphere)

Format

piosphere is a list of 4 components.

veg

is a data frame containing plant species cover

traits

is a data frame with plant traits

env

is a data frame with environmental variables

habitat

is a factor describing habitat/years for each site

Examples

data(piosphere)
names(piosphere)
afcL <- dudi.coa(log(piosphere$veg + 1), scannf = FALSE)
acpR <- dudi.pca(piosphere$env, scannf = FALSE, row.w = afcL$lw)
acpQ <- dudi.hillsmith(piosphere$traits, scannf = FALSE, row.w = afcL$cw)
rlq1 <- rlq(acpR, afcL, acpQ, scannf = FALSE)
plot(rlq1)
