Rosie’s CV

Rosie’s Project: In collaboration with the United States Forest Service, Rosie’s project aims to track the effects that a controlled burn has on a meadow named Mesa Bluff in the San Bernardino mountains. The goal of the fire treatment is to reduce invasion from Pinus contorta in the meadow, which has also been manually thinned. The study would focus on botanical communities, hydrogeomorphic conditions, and the surrounding forested area before and after the burn. The goal of the research is to assess whether fire has a positive influence on meadow composition, which could be defined as having more species and or having more obligate wetland species.

Michael’s CV

Michael’s Project: Michael plans to study saxicolous lichen communities of serpentinite rock outcrops along a coast-inland environmental gradient. His study will compare lichen community characteristics, including species composition and percent cover, as well as substrate characteristics, including elemental composition and surface texture, along a coast-inland gradient. Paired non-serpentinite rocks nearby serpentine study sites will also be sampled. The provisional goals of the project are 1) to study how saxicolous lichen communities change along a coast-inland gradient, 2) to compare how maritime influence might differentially impact saxicolous lichen communities on different rock substrates, and 3) elucidate the role of rock elemental composition and surface texture on lichen community structure and composition.
