Fungi Decomposition Rates in Relation to Growth Rate and Moisture Tolerance
- Ana SammelMathematicsUndergraduate Student
- Emma VillegasMathematicsUndergraduate Student
- Bridget OppermanMathematicsUndergraduate Student
Researchers found that fungi that grow faster tend to be less resistant to changes in temperature and moisture. Exploring the relationship between a fungus’s growth rate and moisture tolerance, our team used a system of differential equations to model the decomposition rates of woody material by different fungi to understand how decomposition would be affected when the species are in competition.
Future Flights
- Jaye ChangEcological RestorationUndergraduate Student
In hopes of increasing STEM students in colleges this project is geared towards high schoolers with the idea that since they are quite adept to todays technology they may be interested in drone technology, either flying, programing, or learning how drones help in the scientific community.
Gender Equity in Wildlife Publishing: A Census of 22 Years of Authorship in the Journal of Wildlife Management
Rebeca Becdach, Wildlife Graduate Student
College of Natural Resources & SciencesVarious studies have documented gender inequity in scientific fields, including medicine, computational biology, the physical sciences, and ecology. A clear indicator of this bias can be seen in the disparity between men and women authorship of scientific papers. This study describes gender diversity in wildlife publishing across institutions, countries, and study species taxa in recent decades. We reviewed all research articles published in the Journal of Wildlife Management from 1999 to 2020 and collected author names and affiliations. We classified the gender of each author using Genderize.io, and calculated the men:women ratio of first and co-authors over time.
Germination and Survival in Knobcone Pine Seedlings in a Common Garden Experiment at Schatz Demonstration Tree Farm

- David GreeneForestry and Wildland ResourcesFaculty
This study examines knobcone pine (Pinus attenuata) germination success from stratification to transplanting into a common garden at the Schatz Demonstration Tree Farm. Seeds were sown in containers in the greenhouse after three week of cold stratification and transplanted to garden beds a month later. Of 840 seeds sown, 538 were germinated (64%). 256 seedlings were outplanted and 192 of these survived (75%±15). The seedlings grew to an average height of 7.5 cm ± 2 cm. Our findings are part of a larger study to understand the water requirements for the survival of tree germinants in a Mediterranean climate.
Great Egret (Ardea alba) Abundance Between the Brackish Pond and Restored Tidal Habitat During High Tide and Low Tide
- Giselle RangelWildlife DepartmentUndergraduate Student
Brackish and tidal habitats are one of many habitat types that support an extensive amount of bird populations in wetland ecosystems (Stolen et al. 2007). However, tidal fluctuations can be of an influence in abundance for Great egrets between many habitat types. The objective of this study is to understand if Great egret abundance is influenced between the brackish pond and the restored tidal habitat as well as certain tide periods of the day.

Habitat Preferences and Distribution Patterns of Salamanders In the Arcata Community Forest
Tristan Ray, Wildlife Undergraduate Student
College of Natural Resources & SciencesThis study investigates the spatial distribution and habitat preferences of plethodontid salamanders within the Arcata Community Forest in Humboldt County, California. By examining salamander abundance in relation to surface water proximity and soil moisture content during the winter-spring period, I aim to identify key environmental factors influencing their distribution. This research highlights the importance of understanding seasonal variations and the complex interrelationships between salamanders and their habitat within diverse forest ecosystems.
Habitat Selection of American Crows in Eureka, CA
Christina Parra, Wildlife Undergraduate Student
College of Natural Resources & SciencesI looked at habitat selection of crows within the city of Eureka. I conducted point count surveys to compare the number of crows within residential/commercial areas (urban) and park areas to see which habitat type crows prefer.

- Logan ScherfWildlifeGraduate Student
A research project that investigates what type of habitat black bears choose when it comes to vegetation density.
