#' Adjacency matrix for focal and adjacent assemblages
#'
#' This is a square matrix containing information abount the presence-absence of each focal cell assemblage and its respective neighborhood assemblages, following the chessboard queen's case.

#' Presence-absence matrix of Australian passeriformes
#'
#' This is a presence-absence matrix for passeriformes obtained from Australian grid-cells. Each column represents a specific passeriforme species, while each row corresponds to an assemblage (or grid cell) within the Australian grid-map. All passerine range maps were sourced from the BirdLife platform.

#' Phylogenetic tree of passerines from Australia
#'
#' This is a list contaning 100 phylogenetic trees of passerines from Australia. Each object within the list corresponds to a sampled phylogeny of class "phylo". The phylogenies are subsets obtained from the global bird phylogeny (https://birdtree.org/) made available by Jetz et al. (2012) in their published research, "The global diversity of birds in space and time".
