Determinants of the taxonomic and foraging guild structure of aquatic and terrestrial bird communities. Variables that contributed significantly to each variable group in variance partitioning at different landscape scales (500 m, 250 m, 125 m) are listed. PC1 characterizes the main environmental gradient, while the different MEM vectors represent spatial gradients based on Moran’s Eigenvector Matrices
