  • Abstract:
    Because of white-nose syndrome, the northern long-eared bat (Myotis septentrionalis) is experiencing rapid population declines across the majority of its range. This decline has prompted increased regulatory protection and thus an increased need for effective habitat management strategies. Insight into the species habitat associations, however, is a prior necessity to ensure management practices are biologically relevant. Understanding these relationships requires a holistic approach that addresses the multiple ways in which the species is interacting with its environment. The objective of this thesis was to address these relationships following a multi-scale approach that assessed the factors associated with roost tree selection, distribution, and habitat use. The author conducted a quantitative meta-analysis of all northern long-eared bat roost-selection studies, thus enabling inference across the range of the species. Secondly, the author sought to understand the factors associated with the northern long-eared distribution in Nebraska by conducting a multiscale occupancy study with four acoustic survey stations nested within 101 10 km x 10 km grids distributed across Nebraska. Lastly, to assess factors associated with multiscale occupancy at finer spatial scales, the author combined presence/absence results from 5 intensively sampled study sites in Nebraska with on-the-ground habitat measurements.
