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.
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.
Soil compaction increases runoff and erosion. Students characterized and studied the cause of soil compaction at multiple sites.
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.
These projects review the effects of wine-growing on water and other natural resources. Biodynamic agriculture and other sustainable practices are recommended for reducing environmental impacts. Ethical issues are explored.
Despite decreased vegetation height, thatch depth, and increased soil compaction, cattle grazing did not impact the observation rate of ground-dwelling grassland vertebrates.
Tidal salt marshes are important carbon sequestration environments. We analyzed sediment gathered from three core samples at varying distances from a tidal channel to determine carbon accumulation for the past century.
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.
