Wailaki Postpositions

College of Arts, Humanities & Social Sciences

Wailaki is an indigenous language within the Dene (Athabaskan) language family, historically spoken within the Eel River Basin. This project examines postpositions found in Wailaki texts. Unlike English which has a system of prepositions, Wailaki has a system of postpositional suffixes that indicate an object’s position in space relative to another. Words in English such as at, in, during, outside, next to, etc. modify a noun to indicate position, whereas in Wailaki this is accomplished with a suffix. Some are incorporated into verbs, as well as temporal expressions. This goal of this research was to compile a list for future language study, and use by second language learners.

WASTING DISEASE EFFECTS ON PISASTER OCHRACEUS PREY POPULATIONS

College of Natural Resources & Sciences

The presence of Sea Star Wasting Disease (SSWD) has caused fluctuations in the abundance of sea stars in the intertidal. Pisaster ochraceus is a keystone predator of the intertidal (Bates, et al., 2009) and has an increased potential to alter the food web now that SSWD has manifested itself within the population. It is a consumer of several species of chiton, snails, and limpets (Paine, et al.,1980) found in our coast’s intertidal communities. Due to the fluctuation in populations of the Pisaster ochraceus, fluctuations of predation should occur as well. Like most predator prey population models predator population size should inversely affect prey population size.

Water Adsorption on Environmental Metal Oxides Determined by the Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) Technique

Chris Harmon, Chemistry Faculty

College of Natural Resources & Sciences

Clouds are a critical component of the atmosphere, which predominantly cools the planet by scattering solar radiation back to space. Particulate matter (PM) are small solids suspended in the air that can initiate the seeding process for cloud formation, where environmental metal oxides (EMO) are one of the dominate types of PM. This process is directly related to the relative humidity (RH) above the PM surface and how much water it absorbs. PM collects sparingly small molecular layers of water before undergoing bulk scale water uptake. Details of water uptake at this level are still lacking in the literature, and we desire to quantify water uptake on atmospheric PM to enhance climate models.

Water Adsorption/Desorption on Environmental Metal Oxides Determined by the Diffuse Refractive Infrared Fourier Transform Spectroscopy (DRIFTS) Technique

Cesar Fernandez, Chemistry Undergraduate Student

College of Natural Resources & Sciences

Clouds affect terrestrial cooling by scattering solar radiation back to space. Particulate matter (PM) suspended in the air can initiate cloud seeding. This process is directly related to the relative humidity above the PM surface and water adsorption. In the initial stages of this process, PM collects sparingly small layers of water, known as monolayers. Details of water uptake at this level are still lacking in the literature and we desire to quantify water uptake on atmospheric PM to enhance literature values.

Water conservation

College of Professional Studies

My project is about water conservation based off of Project WET curriculum. I worked with the students in REC 345: Environmental Education to put together 8 activities. The students presents their activities on zoom. It’s a 2 day event. 4 groups present on the first day then the other 4 present in the second day.

Water Conservation’s Affect on Tribal Water Rights

College of Professional Studies

This poster will focus on what the effects of the water conservation efforts of San Diego County have on the Kumeyaay peoples’ Tribal Water Rights.

Water Management System of the Classic Maya of Palenque (A.D. 250-900)

College of Arts, Humanities & Social Sciences

The scope of this research is to understand the dynamic relationship between the Classic Maya of Palenque and water. The research presents geographical features, climate, techniques, and technology used to harness water. Furthermore, the activities of the Classic Maya of Palenque (A.D. 250-900) involving water will be presented and elaborated as dynamic casual processes revealing and reconstructing cultural aspects. The investigation of the water management of Palenque system reveals the relationship between functionality and Maya ideology .The dynamic relationship between the Classic Maya of Palenque water management

Water Temp. & Clarity Effects on Diving Duck Duration Under Water

College of Natural Resources & Sciences

My research project took place at the Arcata Marsh looking at two diving duck species (Greater Scaups and Buffle Heads) and determining whether water temperature or water clarity effect the the duck's duration underwater.

Watershed Base Plane

College of Arts, Humanities & Social Sciences

Surveying Campbell creek watershed, located in north eastern Humboldt county on the edge of the Hoopa Indian Reservation, implementing mitigation plans for conservation and restoration. There are many environmental impacts that are hazardest to the water runoffs and aquifers such as legal/ illegal cannibus grow, illegal solid waste dumping, and sedimentation from old logging roads. Building maps would provide baseline information for measuring activity that can be harmful to the ecosystem that provides an abundance of resources for a complex bio-diversity and cultural resources for the Hupa Tribe.

Waves of Friends at the Dunes

College of Arts, Humanities & Social Sciences

Friends of The Dunes is a an organization that is heavily involved with building community through various educational and stewardship programs. Our project revolved around outdoor pubic outreach and child education. Local schools have the opportunity to learn about biodiversity and conversation of coastal ecology.
