Research laboratories that primarily host undergraduate researchers can face challenges in undertaking multi-year or long-term research projects. It can be difficult to maintain momentum for the project, keep consistency between student researchers, and retain institutional knowledge. Team Caddis is a group of undergraduate researchers at the University of California, Berkeley who work collaboratively on small-scale, iterative research questions on caddisflies and other benthic macroinvertebrates. Team members include students with a wide range of experience and skills from novice researchers to senior thesis students through collaboration. This research and learning space centers on social framings hypothesized to signal inclusion and belonging for all students. Team members work together using a set of collaboration workflows to collaborate to reduce errors in sample and document management. Senior lab members conducting senior thesis projects serve as near-peer mentors for novice students who assist in their field or lab work. Over the past 10 years, ~70 undergraduate members of Team Caddis have contributed to museum and ecological studies including: developing methods for imaging fluid-based Trichoptera collections, sorting and identification of monthly light trap samples from an intermittent stream in California, species distribution models of California Caddisfly genera, exploring wing venation for species associations of adult caddisflies using geometric morphometrics, and developing species description and illustration pages for the 300+ species of California caddisflies. Several team members have performed bioassessments of urban streams in the San Francisco Bay area. Members of Team Caddis participate for ~2.5 semesters, experience an increased sense of belonging in research spaces, learn to collaborate, and develop research skills.
