Resource-limited regime features community-level environmental filtering.

(A) Presence (black) or absence (white) of all species in all 1,000 communities from the original simulations of Fig 2. (B, C, D) We initialized 200 new communities for each of the three examples highlighted in Fig 2A, by randomly choosing sets of 100 species from the regional pool. Each panel shows the projection of final community compositions {Ni} onto the first two principal components of the set of compositions.
