#' Species abundance data from three habitats
#'
#' This data set consists of the abundance and phylogenetic tree of 46 vascular plant species collected
#' in the period 2002-2009 along the Tyrrhenian coast from three successively less extreme foredune
#' habitats: emboryo dunes (ED, 17 species), mobile dunes (MD, 39 species) and transition dunes (TD, 42
#' species). See the vignette for part of the data in the required input format, and Carboni et al. (2010, 2011) for sampling details and habitat descriptions.
