One House is a Home for Many: Temporal Partitioning of Vertebrates on an American Beaver Lodge

Abstract. American beavers (Castor canadensis) are emblematic of diverse and dynamic freshwater ecosystems across North America. Numerous studies have described positive associations between beaver-modified habitats and biodiversity across a wide range of taxa. Yet few studies have documented biodiversity associated with the epicenter of beaver-modified habitats – the beaver lodge. We used an internet-connected, solar-powered, time-lapse camera system to examine daily and seasonal temporal partitioning amongst vertebrate taxa that visited an American beaver lodge in south-central Nebraska over 9 mo. We observed at least 28 species on the lodge, and many organisms were present during discrete daily and seasonal time periods. These observations provide a more holistic view of a widely recognized, yet understudied, component of beaver-modified habitats. Future use of similar visual-recording systems may reveal that other animal structures, such as burrows, nests, and hives, are prominent ecosystem components in the wild.
