Bioregions are predominantly climatic for fishes of northern lakes
Abstract Aim Recurrent species assemblages integrate important biotic interactions and joint responses to environmental and spatial filters that enable local coexistence. Here, we applied a bipartite (site–species) network approach to develop a natural typology of lakes sharing distinct fish faunas...

Abstract Aim Recurrent species assemblages integrate important biotic interactions and joint responses to environmental and spatial filters that enable local coexistence.

We then compared the roles of key biogeographical factors to evaluate alternative hypotheses about how fish communities are assembled from the regional species pool.
