Ongoing Projects

There is always a lot going on! We have new ideas we are trying out, a main project that is the focus of work, and old projects we are revisiting with better methods or to follow up on related questions. Here are some of our current projects:

What is the effect of density on juvenile growth and survival? 

We measured juvenile roly polies over 12 weeks in low and high density treatments.

Do introduced woodlice prefer plant foods that are local or from their native habitats?

We offered woodlice a choice between European sage and local sage plant leaves and measured how much they ate.

Why do roly polies leave soil and move across concrete areas? 

We are using pitfall traps to capture individuals as they move around the campus. We also have built habitat "microcosms" to investigate this question in a controlled environment.
