Biology graduate student Karli Rogers received first place in her
category at the 12th annual Susquehanna River Symposium student
poster competition on November 10–11, 2017, at Bucknell University.
symposium was attended by more than 300 professionals from
Pennsylvania, New York, New Jersey, and Delaware, including
students, faculty, scientists, engineers, policy makers,
consultants, and community members. Over 80 posters were
presented by students and faculty from 16 universities.
Rogers' poster, titled "Assessment of brook trout passage through
ambiguous culvert barriers in Pennsylvania headwater streams,"
describes a nearly two-year study about the impacts that roads
constructed over streams have on fish populations. Rogers
recorded movement patterns of brook trout, Pennsylvania's state
fish, through culverts that carry stream water underneath roads. These culverts divide and fragment otherwise cohesive fish
populations by impeding migration upstream. Rogers discovered how
culvert design interacts with environmental conditions to
determine passage rates by brook trout. Her work has implications
for improving habitat restoration for this high-priority fish
This project represents a collaborative effort between IUP biology
assistant professor David Janetski and associate professor Joe
Duchamp, Jonathan Niles (Susquehanna University), and Shawn Rummel
and Kathleen Lavelle (Trout Unlimited).
Rogers has also presented
her research at national conferences in North Carolina and
Yellowstone National Park.
