Role of p38 in glioma
- Angelica RomeroBiological SciencesUndergraduate Student
- Casiana GonzalesBiological SciencesUndergraduate Student
Gliomas are highly malignant intracranial tumors that result in a low survival rate due to an invasive phenotype and its diffuse nature. As a result, tumorigenic stem-like glioma cells are poorly targeted by conventional therapies. MAPK kinase 3 (MKK3) has been found to be a key upstream activator of the p38 MAPK protein and is upregulated in invasive glioma cells. Recent evidence suggests that interfering with MKK3 signaling through the inhibition of p38 can inhibit tumor cell invasion in vitro (Demuth et al. 2007). We are interested in examining the role of p38 in glioma through the ability of these cells to form tumor-like colonies in soft agar with modifications in Lgl1 gene expression
Role of Recreational Trailways and Cover Objects in Relation to Terrestrial Salamanders
Anthony Gomez, Wildlife Undergraduate Student
College of Natural Resources & SciencesRecreational trailways are becoming an ever-present component within community forests, nature reserves and national parks, with the effects on local wildlife just beginning to be understood. Prior research holds that regular trailway maintenance increases microhabitat availability for salamanders and results in increased densities. I conducted a 3-month study in a community forest in northwestern California, and used a standardized nighttime paired-field survey technique to assess for cover objects and salamander surface activity.
Rolling with Pollies: Soil moisture effect on recovery from conglobation in the Common Pill Bug, Armadillidium vulgare
Jade Coulter, Wildlife Undergraduate Student
College of Natural Resources & SciencesPill bugs roll into a ball for more reasons than to protect themselves! They may also be conserving water, thermoregulating, or it may all be up to individual boldness. My research investigated whether soil moisture would affect the amount of time it took for pill bugs to unroll. I found that there was no correlation between sex, length, soil moisture, and the amount of time they spent rolled up. However, there was a great variation among individuals.
Rooftop farming in Hong Kong
- Ka Ki LiEnviornmental Science ManagementUndergraduate Student
The idea of this study is to conduct more research on farming in the city, to be specific, Hong Kong. As I grew up in Hong Kong, space is one of the biggest challenges in the city. While citizens are looking for ways to implement their lifestyle, rooftop farming can be one of the great opportunities to build up a community around the neighborhood, provide fruits and vegetables for the residents, and promote a healthy living lifestyle. While promoting the idea of rooftop farming, there are obstacles that the residents need to be overcome. Therefore, I will be analyzing the ecosystem, finance, and government policy that might help the city farmers in Hong Kong.
Sacramento Pike Minnow in the Eel River
- Vincenzo BarogaFisheriesUndergraduate Student
- Alexander EatonFisheriesUndergraduate Student
In our presentation, we will be researching and presenting the historical, and current effects in the Eel River regarding the invasive Sacramento Pike Minnow. This fish was introduced into the Eel River watershed in 1962 and has been an issue for people who depend on the river for the past 45 years. The pike minnow is a species that eats juvenile salmonids (salmon, trout, steelhead). Salmonids are extremely important to the eco-system as well as the people who rely on it. The Wiyot people depend on healthy salmon runs each and every year as a source of food, and more importantly in today's day and age, a source of income.
SAL: A new method for modeling stream flow in small watersheds
Jim Graham, Environmental Science & Management Faculty
College of Natural Resources & SciencesStreams Across Lands (SAL) is a new stream flow modeling method for small watersheds. SAL is based on standard hydrological equations for water flow on the surface, through soil, and in stream channels. The model can be used with standard spatial datasets including Soil Survey Geographic Database (SSURGO, NRCS) and National Land Cover Data (NLCD). SAL was tested primarily within the Elder Creek watershed and showed a high level of correlation with the observed discharge at the USGS station. SAL includes an easy-to-use graphic interface within the BlueSpray GIS application and provides a variety of graphic outputs for use in watershed analysis and community outreach.
Salamander activity: The impact of abiotic factors on salamander movements in Northern California
Luke Leuty, Wildlife Undergraduate Student
College of Natural Resources & SciencesThis poster focuses on studying the relationship between abiotic factors and salamander activity. We predict soil saturation to be the biggest factor influencing salamander activity. We also examine soil temperature, air temperature, daily precipitation, and accumulative precipitation and their affects on salamander activity.
Salamander Habitat Abundance Based on Water Flow
Chris Vignery, Wildlife Undergraduate Student
College of Natural Resources & SciencesA study related to finding out a relationship between the abundance of salamanders and the flow of water in the Arcata community forest.
Salamander occupancy according to log shape and condition in Humboldt County
Riley Tetzlaff, Wildlife Undergraduate Student
College of Natural Resources & SciencesFor my research project I studied whether or not the shape and condition of a log effected the occupancy rate of salamander, and according to my data I was half right.
Salinity influence in feeding of dabbling and diving ducks
- Cesar RochaWildlifeUndergraduate Student
Tested to see if salinity levels in water had an affect on feeding in water fowl. Looking at dabbling and diving ducks, I saw which one exhibited most feeding. Species studied were Buffleheads as diving ducks(Bucephala albeola) and Mallards (Anas platyrhynchos) as dabbling ducks.
