Theoretical Data Set used in Ricotta and Pavoine (2015) in Ecological Indicators

Description

The data set was used in Ricotta and Pavoine (2015) to show how the coefficients of multi-site dissimilarity that they developed can be applied to data.

Usage

data("RP15EI")

Format

The format is a list of 4 data frames. Each data frame gives the presence (1) and absence (0) of 10 species (columns, S1-S10) in 8 plots (rows P1-P8). These data are characterized by different levels of nestedness and turnover in species compositions between sites.

M1: Intermediate nestedness and turnover.

M2: Perfectly nested pattern.

M3: Very high species turnover.

M4: Random configuration.
