Dark Taxa: biodiversity of undescribed arthropods on islands using DNA

Environmental Science, Policy and Management
Applications for Spring 2025 are closed for this project.
Biodiversity surveys often accumulate many many insect and spider specimens, but it is usually hard to figure out what the species actually are. Many species are not yet described and many are found in an area for the first time, or the species are not yet in DNA databases. In this project we are trying to figure out what the species in biodiversity surveys from Pacific Islands are, especially spiders, leaf-feeding arthropods and soil arthropods. This is part of a large project to understand the origins of biodiversity in the islands of the Pacific, including French Polynesia, Hawaii, the Marianas, and Okinawa, Japan. We are especially interested in the role of invasive species in the biological communities of these islands.
Role: Students will be working with specimens of arthropods (insects, spiders, millipedes, etc) to sort and prepare specimens for DNA extractions. Specific tasks may include specimen identification, measuring specimens, recording functional characteristics, using sterile lab techniques, and using micropipettes for basic laboratory tasks.
Qualifications: Interest in learning or prior experience in arthropod identification (e.g. insect or spider biology). Desirable but not essential: prior experience with micropipettes, DNA extraction, gel electrophoresis, PCR.
