Faculty Research Interests
Fisheries Faculty
DR. SUE COLVIN, PH.D.
Research interests:
- Investigating how stream connectivity & flow permanence impact fish assemblage metrics such as richness and endemism.
- Investigating patterns in fish species diversity & traits in relation to aquatic habitat type.
- Studying habitat & flow requirements for endemic Ozark and Ouachita Mountain fishes.
Current research projects:
- Investigating the impact of low pass concrete barriers, culverts, and bridges on Ozark stream fishes.
- Investigating variables associated with endangered and threatened fish species expenditures.
- Investigating the evolution of AFS publications over time.
Dr. Charles Gagen, Ph.D.
Research interests:
- Factors influencing the distribution and abundance of stream-dwelling fishes, both game and non-game species.
- Assessing aspects of fish movement and factors that potentially restrict movement are among the hot topics.
- Assessing factors that affect water quality and quantity.
Current research projects:
- Aspects of Smallmouth Bass spawning in a stream system that is prone to drying in the summer
- Studies of leaf-pack processing in the same system.
- Study of phytoplankton dynamics relative to environmental variables in a southern reservoir.
Dr. John Jackson, Ph.D.
Research interests:
- Management of reservoir and riverine fishes.
- Environmental impacts of large river manipulations.
- Farm pond management.
Current research projects:
- Investigating movement patterns of sauger in the Arkansas River system.
- Examining stocking patterns of white and black crappie in Arkansas reservoirs.
Wildlife Faculty
Dr. Chris Kellner, Ph.D.
Research interests:
- Population ecology of birds and lizards, especially how habitat structure influences use of space and demographics.
- For birds, I am particularly interested in how silvicultural practices influence community structure and population size.
- For lizards, I am particularly interested in how habitat complexity influences population size, movements, survival, and individual growth.
Current research projects:
- I am currently comparing population trends of rusty blackbirds among different physiographic regions within Arkansas. One of my graduate students is also investigating home range and habitat selection in urban landscapes in Central Arkansas.
- I am also investigating growth patterns of prairie lizards among three structurally different habitats.
Dr. Jorista Garrie, Ph.d.
Research interests:
- Mammalian population ecology and conservation biology.
- Interactions between mammals and their food sources.
- Movement ecology of small and large mammals.
Current Research projects:
- Bat foraging ecology in response to prescribed burns, in Northwest Arkansas.
- Demographics and birth sex ratios in white-tailed deer in Arkansas.
Dr. Tom Nupp, Ph.D.
Research interests:
- Mammalian community ecology.
- GIS applications in Wildlife Ecology and Management.
- Management of endangered species
Current research projects:
- Examination of disturbance patterns at endangered Interior Least Tern colonies on the Arkansas River.
- Interactions among small mammals, mesocarnivores and endangered American Burying Beetles.
- Examination of small mammal carcass disturbance and decay.
