Currently, in collaboration with Dr. Elizabeth Shea at the Delaware Museum of Nature and Science, my students are exploring predator prey interactions using marine gastropod shell collections. Predators of marine snails often leave evidence of attempted and successful predation attempts on the shells of their prey, including drill holes and cracks in the shells. Paleontologists have used this type of predation evidence to describe ancient ecological interactions. In the Krumm lab, we are applying this technique to recent shell collections, allowing examination of predator-prey interactions of marine gastropod populations that are otherwise challenging to access due to location and depth. Our lab is currently working on:
- Characterization of predator shell damage in Family Terebridae. Does damage differ in frequency, size, and other characteristics across species in recent (non-fossil) shells
- Do different drilling predators of the Terebridae, distinguished by the shape of the drill hole, differ in where they attempt to create a hole in the shell? Is the hole location impacted by predator size or shell outer wall thickness?
The Krumm lab is also examining morphological variation in Family Xenophoridae, the carrier shells. These marine gastropods attach found objects in their environments to their shells, including shells and rocks. There are multiple hypotheses that attempt to explain this attachment behavior. We are currently working on:
- Characterization and comparison of shell footprints between species in Family Xenophoridae. Do we see regional variation within species? Do species with overlapping ranges show similarities in shell footprint patterns, such as width and shape of footprint?
My research and service interests also extend beyond my laboratory at Widener University, leading to the creation of BCEENET (Biological Collections in Ecology and Evolution Network), a research coordination network in undergraduate biology education. Undergraduate research experiences were a pivotal point in my career trajectory, leading me to pursue research in ecology and evolution. I am committed to expanding those opportunities for both my students, and undergraduates beyond my institution. As PI of BCEENET, I’ve had the opportunity to support faculty at diverse institutions in embedding research in their courses as CUREs (Course-based Undergraduate Research Experiences) through CURE development and faculty development workshops. Additionally, I am involved in a large-scale assessment of BCEENET CUREs, demonstrating the value of participating in these CUREs through measures of student belonging and skills building.
