ABSTRACT: We sampled small mammals on island and mainland sites of riverine ecosystems in Sequoyah National Wildlife Refuge. We have conducted two sampling periods consisting of ten sampling sessions in 2016 and 2017. Three islands and two mainland sites were sampled using Y-shaped pitfall arrays consisting of 10 pitfalls connected by drift fences. Fifty-two individual small mammals representing two orders were captured. Rodents and shrews were detected at all sites. After adjusting for catch effort, our analyses showed that there were no significant differences in small mammal detections on the islands verses the mainland sites. However, rodents were detected most often at mainland sites while shrews were detected most often at island sites. The traditional view of islands as sink areas for wildlife populations may not be true for shrews. Islands may be performing as sink areas for rodents in riverine ecosystems, but they may be preferred habitats for shrews. Additional fieldwork scheduled for 2018, including habitat analyses, is expected to better highlight preferred habitat, the varying dispersal abilities of small mammals to riverine islands as well as to clarify their functional role for different vertebrate groups in their surrounding ecosystems.
