In this project, the effects of invasive house mice (Mus musculus) on island invertebrates will be studied by analyzing samples of invertebrates collected from islands of Midway Atoll National Wildlife Refuge (NWR). Mice are present on one Island, Sand Island, but absent on another, Eastern Island, providing a unique opportunity to examine the differences between invertebrate abundance and community composition. The effects of invasive mice on invertebrates have not been studied in great detail; however, it is known that mice can have irreversible and devastating effects on island ecosystems. Eradication of an established invasive species can greatly affect the other populations of the ecosystem. Therefore, it is important to study the possible outcomes and effects the eradication may cause to prevent any further environmental damage and guide management and on-going restoration efforts post-eradication.
