This subterranean habitat makes burrowing crayfish difficult to sample and results in a paucity of data on their distributions, habitat use, and natural history. In this dissertation, I examined the biogeographical patterns of burrowing crayfish species in the Midwestern United States. In chapter 1 I reviewed relevant literature and quantified the knowledge gaps on these species globally. In chapters 2 and 3 I evaluated the impact of land management on local distributions and found that burrowing species, as non-target taxa, can still benefit from conservation practices. In chapter 4 I used ecological niche modeling to explore if generalist burrowing species display niche conservatism and can act as distributional surrogates. I found that even wide-ranging generalist species with sympatric ranges could not be used as surrogates for each other. Further, these crayfish exhibited species-specific habitat associations and using a supraspecific model could not predict the presence of these species better than their single-species models. Finally, in chapter 5, I tested the niche breadth – range size hypothesis on wide-ranging and narrowly endemic species. I found that burrowing crayfish do not always exhibit patterns expected from traditional ecological theory.
