Red-Tailed and Red-Shouldered Hawk Habitat Usage Throughout Humboldt County

Pouya Kazemi, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Studying if the habitat type has an effect on the what age hawk will be using that territory, either adult or immature. Looking at four habitat types, open, forest, urban and water. There was no significance in habitat type in relation to age.

Redwood Coast Beer Trail

Matthew Gerber, Kinesiology & Recreation Administration Undergraduate Student

College of Professional Studies

From the primitively-brewed ‘steam beer’ of 19th century Eureka taverns, to the nano-brewed Hazy DIPA in a Crescent City warehouse today -- brewing culture remains a key social element and economic driver in Northern California's Redwood Coast. The Redwood Coast Beer Trail is an experiential destination marketing campaign that applies the principles of gastrotourism to advertise the robust craft brewery scene of Humboldt and Del Norte counties as distinct tourism assets. The Redwood Coast Beer Trail poster is a self-guided, self-paced wayfinding aide that empowers local and non-local visitors to experience the unique oddities and attributes of the region’s craft beer and cider producers.

Risk of Concussion Based on Position in Men’s and Women’s Collegiate Soccer

Devin Hauenstein, Kinesiology & Recreation Administration Graduate Student

College of Professional Studies

Identification of correlations between rates of concussion and soccer positions played will lead to improved safety protocols and athlete health. Improvements can be identified by understanding the minutes played per position as fatigue is a risk factor for obtaining a concussion, in training or in game conditions by men and women soccer players. PURPOSE: To determine whether a correlation exists between minutes of soccer played, soccer position played, and the incidence of concussion among men and women collegiate soccer players.

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 & Sciences

Pill 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.

Safety Plan

Alyssa Lawrence, Social Work Graduate Student

College of Professional Studies

We collaborated with Dr. Bayan at Waterfront Recovery Services to create a post-discharge safety plan for patients. The safety plan will be used and implemented on each individual client to reduce substance use and create a life of sobriety.

SAL: A new method for modeling stream flow in small watersheds

Jim Graham, Environmental Science & Management Faculty

College of Natural Resources & Sciences

Streams 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 & Sciences

This 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 & Sciences

A 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 & Sciences

For 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.

Sand Crab, Emerita analoga, Burrowing Time in Relation to Relative Abundance in Humboldt County

Andrew Cha, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Finding the relation between grain size and burrowing time of sand crabs at study sites of Samoa, Mad River, Moonstone, Clam and Trinidad state beach. Relative abundance is measured at each study site to determine if there is a correlation between grain size, burrowing time and habitat selection.
