Description
Summary: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 and provide a detailed, hierarchical view of their bioregions. We then compared the roles of key biogeographic factors to evaluate alternative hypotheses about how fish communities are assembled from the regional species pool. Location: Ontario, Canada and the Upper Midwest, USA. Time period: 1957–2017. Major taxa studied: Freshwater fishes. Methods: Bipartite modularity analysis was performed on 90 taxa from 10,016 inland lakes in the Southwestern Hudson Bay, Mississippi River, and St. Lawrence River drainages, uncovering bioregionalization of North American fishes at a large, subcontinental scale. We then used a latent variable approach, pairing non-metric partial least-squares structural equation modelling with ... : Fish occurrence records in portions of the Southwestern Hudson Bay, St. Lawrence, and Mississippi River drainages were compiled from existing datasets in Ontario (Aquatic Habitat Inventory; Dodge, Goodchild, Tilt, Waldriff, & MacRitchie, 1987), Michigan (Status and Trends; Wehrly, Carter, & Breck, 2021), and Minnesota (Index of Biotic Integrity; Drake & Pereira, 2002). Fishes were sampled from lakes, ponds, reservoirs, and embayments during the open-water season over a 60-year period (1957–2017) using a combination of netting, trapping, and electrofishing. Records of 132 fish taxa were initially compiled across 11,112 lakes, but several species and lakes were removed (see manuscript for selection details). Our final dataset included 90 taxa across 10,016 lakes (mean species richness = 8). References Dodge, D.P., Goodchild, G.A., Tilt, J.C., Waldriff, D.G., & MacRitchie, I. (1987).
