Cheryl HortCheryl-Hortonon

Cheryl was co-advised during her M.S. degree at OSU by Dr. Katie Dugger and Dr. Robert M. Suryan. Her research goals were to better understand top-down impacts on colonial nesting seabirds over a range of spatio-temporal scales.  Cheryl defended her thesis in June 2014, titled: Effects of bald eagle (Haliaeetus leucocephalus) disturbance on the common murre (Uria aalge) meta-population breeding in coastal Oregon. Cheryl now works for the US Geological Survey’s Western Ecological Research Center in California.

Scott JenniJenningsngs

Scott’s research interests include understanding how reproductive success varies among individuals in a population, and how long-term data sets can be used to understand how populations respond to changing environments.  His M.S. thesis research was conducted on Ross Island, Antarctica, where he explored parental factors affecting growth of Adélie Penguin chicks, and how variation in growth rates affect survival to independence. Scott defended his thesis titled: Provisioning, Growth and Survival of Adélie Penguin Chicks at Cape Crozier, Ross Island, Antarctica in March 2015. Scott is permanently employed as Avian Ecologist at the Cypress Grove Research Center, with Audubon Canyon Ranch in CA.

kevyn

Kevyn Groot

For her M.S. research, Kevyn studied the demographics of the Columbian black-tailed deer in Oregon, a subspecies of mule deer that has experienced a widespread decline since the 1980′s.   She analyzed a data set collected by Oregon Department of Fish and
Wildlife during a 6-year study of radio-collared black-tailed deer in southwest Oregon during 1994-2000, and estimated seasonal and annual survival rates by sex and age classes.  Kevyn graduated June 2015 and her thesis was titled:  Historic Survival Rates and Cause-Specific Mortality for Columbian Black-Tailed Deer in Southwest
Oregon.

Lizz

Lizz Mulligan Schuyler
Lizz’s research interests include the population dynamics, disease ecology, and habitat selection and use of large ungulates.  She studied annual and seasonal survival rates and cause-specific mortality of female mule deer in eastern Oregon Lizz defended her M.S. thesis titled: Survival Rates and Cause-Specific Mortality for Mule Deer in South-central Oregon in October 2015.  She is continuing to pursue her research interests in Mule Deer as a PhD candidate at OSU under the co-advisement of Dr. Dana Sanchez and Dr. Lisa Ellsworth.

Lee Foster
Lee was co-advised during his M.S. research by Dr. Katie Dugger and Dr. Christian Hagen.  He studied the demographics and habitat use of female Greater Sage-grouse in relation to a recent large-scale wildfire.  Lee graduated in May 2016 and his thesis was titled: Resource Selection and Demographic Rates of Female Greater Sage-Grouse Following Large-Scale Wildfire.  Lee is now permanently employed by Oregon Department of Fish and Wildlife as the Sage-Grouse Conservation Coordinator in Hines,OR.

Chad Marks-Fchadife

Chad is Oregonian by birth and holds bachelor’s degrees in both wildlife and music performance. He is also a federally certified tree-climbing instructor and has a strong focus on canopy science where he studies arboreal mammals, raptors, and lichens. Chad was co-advised during his M.S. degree by Dr. Katie Dugger and Dr. Eric Forsman.  His M.S. research project revolved around red tree voles, and efforts to determine the age structure of wild populations and estimate detection rates and population density of tree voles by forest age class in Oregon coastal forests.  Chad defended his M.S. thesis titled:  Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon in June 2016. He is currently working for the Forest Service investigating the effect of artificial nest structures on red tree vole occupancy in younger forest stands.

Anna Mangan

Anna is broadly interested in the ecology, management & conservation of threatened & endangered species & their habitats, primarily birds.  Her Master’s research focused on Northern Spotted Owl occupancy dynamics & breeding propensity in Mount Rainier National Park, in western WA.  Anna defended her M.S. thesis titled:  Effects of Habitat Characteristics, Weather and Presence of Barred Owls (Strix varia) on Occupancy Dynamics and Breeding Propensity of Northern Spotted Owls (S. occidentalis caurina) in Mount Rainier National Park in June 2018. She is currently on a year-long sabbatical, traveling the world with her husband.

Peter-KappesPeter Kappes

Peter’s research interests focus on the ecology, management, conservation, & restoration of seabird populations & the role marine birds play in island ecosystems.  For his Ph.D. research he investigated the reproductive patterns and success of Adélie penguin breeding at three different colonies on Ross Island, Antarctica.  Peter defended his dissertation titled: The Influence of Alternate Life History Strategies and Natal Conditions on the Reproductive Performance of Adélie Penguins Breeding on Ross Island, Antarctica in March 2019.  Peter is now a research ecologist with USDA APHIS, in Hilo,HI.

Beth2Beth Orning

Beth’s research interests focus on the ecology, management, and conservation of large carnivores, with a particular focus on understanding interspecific competition, spatial ecology, and population dynamics in multi-predator multi-prey ecosystems. For her PhD research, she collaborated with the Oregon Department of Fish and Wildlife to examine the interaction between wolves and cougar in northeast Oregon.  She defended her dissertation titled:  Carnivore Competition: Spatial and Dietary Implications of Gray Wolf Recolonization for Cougars in Northeast Oregon in June 2019.  Beth is now a post-doctoral research at Michigan Tech working on the reintroduction of wolves to Isle Royal.

Leila Duchac

Leila is interested in the ecology and conservation of threatened & endangered species, with a focus on birds. More specifically, she is interested in less invasive monitoring methods for rare, sensitive, and difficult-to-detect species.  She was co-advised during her Master’s research by Dr. Katie Dugger and Dr. Damon Lesmeister.  Her Master’s research used autonomous recording units to detect forest owls in Oregon and Washington.  Leila defended her thesis titled:  Passive acoustic monitoring of owls: two studies in forested landscapes of the Pacific Northwest in August 2019.  She is currently working for the USDA Forest Service, Pacific Northwest Research Station in Corvallis, OR.
