We studied whether bullfrogs eating large amounts of crayfish showed a reduction in the number of native species they consumed.
Soil compaction increases runoff and erosion. Students characterized and studied the cause of soil compaction at multiple sites.
Morales et al 2018: Identification of newt species is a challenge for field biologists.
We used pitfall traps to study arthropod diversity on three pond edge habitats at the Colusa National Wildlife Refuge. The greatest arthropod diversity was found in Tule habitat.
To determine whether or not invasive turtles are a threat to our native species, we compared abundance of red-eared sliders and western pond turtles at three different locations: Turtle Pond on the SSU campus, Mountain Lake in San Francisco, and Roberts Lake in Rohnert Park.
The upper watershed of Copeland Creek is known for its landslides, slumps and debris flows. We evaluated sites on SSU Fairfield Osborn Preserve to determine how slope stability is correlated with rock type, and degree of weathering and vegetation.
Development of a pilot-scale microbial fuel cell system for treating wastewater from wine production
Use of hiking trails can increase erosion, soil compaction, and transmission of Sudden Oak Death pathogen, Phytophthora ramorum, from surface runoff. We conducted a survey to identify sections of trail at the Fairfield Osborn Preserve (upper Copeland Creek watershed) with excessive erosion.
Cardinale et al 2017: We surveyed vegetation in Salmon Creek to determine the impact of invasive species affect the ecosystem.
We found that Sudden Oak Death occurs in bay laurel and European sweet bay trees on SSU campus but that symptomatic leaves are lower on campus than at the Fairfield Osborn Preserve.
