Undergraduate Student
College of Natural Resources & Sciences
Various epiphytes such as lichens, mosses, leafy liverworts, and ferns are known to inhabit the crowns and boles of old-growth conifers and hardwoods. This study looks at the diversity and distribution of epiphytes on a single old-growth Sitka spruce tree. Data were analyzed to test for significant relationships between species richness, abundance, height distribution, and substrate type.

The effects of urbanization and Co2 car emmissons on local bee abundance and species richness. Testing to see what drives bee populations and if there is a negative correlation between Co2 levels and bees' in urban, agricultural, and natural settings and which areas provide the most abundant resources.
Likelihood of agonistic behavior by gull species in Humboldt County based on relative body size

Undergraduate Student
College of Natural Resources & Sciences
This project is a behavioral study on 4 gull species of Humboldt County. Their agonistic behavior was studied, comparing the frequency of agonistic behavior toward members of other species based on relative body-size. This value was compared with the number of birds of each relative size they had access to. I found that most gulls tended to target members of their own species disproportionately, but Western gulls disproportionately targeted members of other species that were larger and smaller in size. This may have implications on gull behavior and management.

Dog World Dog Memes
Ingrid Beha
Anthropology
Undergraduate Student
College of Arts, Humanities & Social Sciences
Memes, photographs or videos that are edited to be satirical and that makes fun of cultural ideologies, are passed rapidly through the internet and phone applications and can end up on hundreds of websites within hours. Methods employed included participant observation, literature review, and screenshot analysis from Facebook and Instagram. Patterns in the types of posts indicate that people of all ages actively seek out dog memes to reduce anxiety and that dog memes are more popular when they are humanized. Dog memes are an artifact of our generation that transcends age groups and allows us to research meme culture that reflects a virtual population.
Urbanization Impact on Native Avian Species Richness

Wildlife
Undergraduate Student
College of Natural Resources & Sciences
The aim of this study was to focus on the richness of native avian species to determine if they are influenced by urbanization. To measure this, point counts were conducted, in which all birds were counted and identified. A total of 30 survey sites were evenly divided between Arcata, Arcata Bottoms, and Eureka, to encompass a gradient of urbanization.
