Current and Former Undergraduate Researchers

Mike Mahoney (B.S. in Forest Ecosystem Science, Fall 2018) is an undergraduate student in the Stella Lab working on his honors thesis. He is interested in the larger role beavers play within forest ecosystems, both from an ecological and a natural resources management perspective. He is studying how beaver foraging impacts forest health, including aspects of both forest structure and non-monetary values such as aesthetics and tree architecture.

---

Giselle Schreiber (B.S. in Environmental Science major with Marine Science minor, Spring 2018) completed her senior capstone project on the influence of several abiotic factors (temperature, precipitation, sediment depth, etc.) on the growth rate of Populus fremontii  (Fremont cottonwood), a keystone riparian tree species in the Sacramento River Valley of California. She was raised in Miami, Florida and has experience working with freshwater and marine fish and invertebrates.

---

Will Fernandez (B.S. in Environmental Science major, Spring 2018) completed his senior capstone project on the impacts of beaver on riparian forest communities surrounding lakes at the Huntington Wildlife Forest in the central Adirondacks.

---

Margaret (“Maisie”) Baronian (B.S. in Environmental Science major with Mathematics minor, Spring 2018) focused her senior capstone project on  how seasona precipitation events impact instream conductivity levels in an urban stream. Conductivity concentrations in streamwater can be used as an indicator for road salt, which is widely applied in the region as a de-icer in winter. She used the statistical software R to model hydrologic conditions in Meadowbrook Creek in Syracuse, NY, using data collected from automated stream gauges.
