Ryan O’Dell

B.S. Plant Biology. University of California, Davis. 2002.
M.S. Soils and Biogeochemistry. University of California, Davis. 2005.

Ryan is a Natural Resource Specialist (Botany/Soils/Paleontology) with the Bureau of Land Management (BLM) Central Coast Field Office in Marina, California (since 2007). The BLM Central Coast Field Office manages about 300,000 acres of Federal public lands in the South Coast Ranges – mostly in Santa Cruz, Monterey, San Benito, and Fresno Counties (western portion).  His education and training is in terrestrial plant ecology and soil science with an emphasis in wildland ecosystem processes, restoration, and rare plant species conservation.  The focus of his work with BLM is rare and endangered plant species conservation and recovery and understanding how land use and natural ecosystem processes influence vegetation type and individual plant species distribution and abundance.  He is particularly interested in plant edaphic endemism and plant species distributions with respect to geology, soil type, topography, and climate.  Most of his recent work on extreme substrate plant ecology has been on serpentine at San Benito Mountain (southern San Benito County) and saline, vertic clay soils in the San Joaquin Desert (western Fresno County).  Ryan specializes in the species taxonomy and ecology of the plant families Onagraceae (Camissonia), Polemoniaceae (Gilia), annual Brassicaceae (Caulanthus-Streptanthus), and tarweeds in Asteraceae.

Rosie Murphy-Deak (Fall 2019-Winter 2022): Defended 03-14-22

B.S. Environmental Science and Management, UC Davis – 2013

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.

B.A. Environmental Analysis, Pomona College, CA – 2010

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.
