NRM student takes top honors at URSA competition

Jessica Herzog, a natural resources management student, won first place overall Tuesday at the 2017 Research and Creative Activity Day hosted by
URSA.

Her research poster on golden eagles’ diets was chosen from
more than 100 entries displayed Tuesday on the first floor of Wood Center. The
event is an annual celebration of undergraduate student research and creative
projects.  Each school chose a Dean’s
Choice Award and representatives from URSA, Undergraduate Research Scholarly
Activity program, picked the top three finishers.

Herzog’s poster also received a Dean’s Choice Award from the
School of Natural Resources and Extension. She will receive $250 for her SNRE award
and $1,000 for her first place overall.

The event was reminiscent of a science fair with undergraduate
students standing by their projects to discuss their work. Research and
creative posters ranged from tsunami wave action and engineering projects to
costume design and food sustainability.

Six students from the School of Natural Resources and Extension
displayed their work, including Trish Levasseur, Kimberly Diamond, Zoe
Marshall, Roger Ridenour and Kelly Schmitz.

Herzog’s project looked at differences in the diets of male
and female golden eagles on the Seward Peninsula. Her poster is titled “Trophic
Niche Partitioning Between Male and Female Golden Eagles in Western Alaska.”

Herzog said the point of her project was “to see if male and
female eagles consumed a different size of prey to avoid competition.” Niche
partitioning refers to the process by which competing species use the
environment differently in a way that helps them coexist. Golden eagle females
are larger than males so she theorized that males might eat
smaller prey.

Her project built on undergraduate research done by Joseph
Eisaguirre, who is now a doctoral student with the UAF Department of Wildlife and
Biology. As part of her research, Herzog analyzed his data and she examined 349
regurgitated pellets and 52 uneaten prey remains from nests and perches. They
were drawn from 46 occupied eagle sites visited in 2014 and 2015 by Eisaguirre
and wildlife biologist Travis Booms, who is with the Alaska Department of Fish and Game’s Threatened,
Endangered and Diversity Program. They assumed that perch samples were from males and nest samples came from females.

Herzog, who is a junior, hopes to continue to study
predator-prey relationships as a graduate student. She is from Butte, Montana.

SNRE Academic Director Dave Valentine, who chose the dean’s
award after consulting with Research Director Milan Shipka, said it was hard to
choose among the projects.

Students displayed the following work: 

• Trisha Levasseur, with mentor Pete Fix: “Recreation
and Travel Across Federally Managed Lands in Alaska: Analysis of Management Meeting Informational Needs of Visitors.”  She examined data collected as part of a
visitor survey conducted last year in Alaska to determine what type of
information is sought by different types of visitors.

• Kimberly Diamond, with Gino Graziano and Katie
DiCristina, “Factors Impacting Dormancy and Viability of Prunus Padus Seeds.”
Diamond studied the dormancy and viability of invasive bird cherry seed. 

•  Kelly Schmitz, with assistance of Greg Finstad, George
Aguiar and Christopher Maio, “Nutritional Impact of Willow Leaves on Reindeer Calves.”

• Roger Ridenour, “The Arctic Biosphere Container:
Beginning the Process of Eliminating Food Insecurity in Remote Alaska.”

• Zoe Marshall, with mentor Milan Shipka, “Sustainable
Agriculture Education Through the Case Study of Wrigley Farm and Alaska Flour
Co.”

• Zoe Marshall, with mentor Pat Holloway:
“Vegetative Propagation of Four Northern Berry Species to Promote Sustainable
Fruit Production in Alaska.” She explored methods of cutting propagation to
seek the best way to propagate honeyberry, haskap, Saskatoon serviceberry and
blueberries.
