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.

Salinity influence in feeding of dabbling and diving ducks

College of Natural Resources & Sciences

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.

Sammich and Rumples Pilot Preview

College of Arts, Humanities & Social Sciences

I received the Undergraduate Research and Creative Award in Fall of 2015, and as per the requirements of the grant I am to present my work at IdeaFest this coming April. It is a children's story nearing the end of its production, and will mostly be a stationary display or booth where I'll gladly do Q&A about the process, where I'd like to see it go, and so forth.

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.

Saudi Women Enforce Freedom of Expression

College of Arts, Humanities & Social Sciences

This project promotes freedom of expression in today’s world by demonstrating advocates in a hostile society creating a movement to show women can be just as competent as men. It is important to acknowledge women are still fighting to receive the benefits of equality in other countries. Women in all parts of the world should be able to engage and contribute within any given community to enhance the quality of society. I find it amazing that women advocates in Saudi Arabia risked their lives, ruined their reputation, and even lost their jobs in order to support the movement by demonstrating their freedom of expression.

Save the Bison

College of Natural Resources & Sciences

For ideafest we plan to enlighten our fellow Humboldtians on how Native tribes are helping to save the bison from extinction. Bison have played a key role in Native culture especially in the great plains . Their bison are like our salmon. The Sioux and Assiniboine tribes of Fork pecks currently have the largest restoration herd, with up to 340 bison living and thriving on their lands. We major in zoology and we decided to focus in on this subject because it is a clear bridge on how Indigenous people make connections between animals and their culture. Thereby, a connection between NAS and Zoology is born and recognized :) .

Scaling Resistance with Channel Length for Carbon Nanotube Networks

College of Natural Resources & Sciences

In order to help inform the applicability of carbon nanotube networks for use as field effect transistors or as biosensors, we have run computer simulations in order to characterize the electrical properties of these networks, and specifically, how the resistance of these networks scales with the channel length for various amounts of metallic wires present in the networks. We find a trend that as the channel length increases, the resistance of the network increases as well. In addition, as the probability of metallic wires present in the network increases, the scaling factor of the resistance, m, increases at a larger constant rate with increasing channel length.

Scanning Electron Microscope Imaging of Nitropentaamminecobalt(III) Chloride ([Co(NH3)5NO2]Cl2) Crystal Structure

David Morales, Chemistry Undergraduate Student

College of Natural Resources & Sciences

Inorganic chemistry is the study of molecules that have properties and behaviors of inorganic compounds, such as metals, minerals, and organometallic compounds. Students in organic chemistry lab used knowledge of coordination compounds to synthesize nitropentaamminecobalt(III) chloride ([Co(NH3)5NO2]Cl2) crystals. Imaging of these crystals using a scanning electron microscope was performed to get a closer look at these crystals to characterize them further.

Scavenging Efficiency in Turkey Vultures (Cathartes aura) at Forested Sites

Ephraim Lowe, Wildlife Undergraduate Student

College of Natural Resources & Sciences

Turkey vultures are well known for their incredible sense of smell due to their large olfactory bulbs, which are even larger than some mammals, such as rats. The study conducted compared the olfaction ability of turkey vultures to local mammals in the area by baiting sites in the Arcata Community Forest with carrion. It analyzed which species arrived to carrion sites first, and how weather, temperature, and humidity affected their ability to locate carrion efficiently.
