Associations between island geographical features and the phylogenetic structure (NRI and NTI) of island mammal assemblages. (Coefficients for best-fitting spatial GLS models using 1000 km source pools with islands smaller than 50 000 km² excluded; see text for details of model-fitting procedures. (a) Land-bridge islands and (b) oceanic islands. ^*p≤0.001; ^**p≤0.01; ^***p≤0.05; ^#p≤0.06.)
