Cat assisted with all of our research efforts in Voyageurs National Park including live-trapping muskrats (Ondatra zibethicus), conducting sign surveys for semiaquatic mammals (muskrats, American mink [Neovison vison], and North American river otter [Lontra canadensis]), and measuring habitat changes in wetlands after muskrat translocations. She led our research into investigating the use of American beaver (Castor canadensis) lodges by muskrats. Cat has a B.S. degree in Fisheries & Wildlife from the School of Natural Resources at the University of Nebraska - Lincoln. She also holds a B.A. in Spanish from the University of Nebraska - Lincoln. Cat is now a full-time wildlife biologist at Voyageurs National Park.
Colleen Piper
Colleen is interested in many aspects of carnivore ecology and wildlife management. For her thesis work, she used multiple years of occupancy data to uncover how landscape changes (e.g., agriculture, energy development) and availability of water affected the spatial distribution of American badgers (Taxidea taxus) in short-grass prairie ecosystems. Her study area covered the entire western third of Kansas, USA, and included almost 400 independent sampling sites. Colleen received her B.S. degree in Fisheries and Wildlife from The University of Georgia in 2018. While at UGA, Colleen was the treasurer (2015-2016) and president (2016-2018) of the student chapter of The Wildlife Society. Colleen is now perusing a Ph.D. at the University of Montana where she is investigating how beavers (Castor canadensis) influence biodiversity across landscape scales. While in our lab, Colleen was an author on work published in Landscape Ecology, Biological Conservation, and Ecology.
Ben Matykiewicz
Ben is interested in how wetland biodiversity is impacted by various management techniques used to control the spread of invasive-hybrid cattails (T. x glauca). His work was focused in Voyageurs National Park, Minnesota. Current cattail management in this region includes the use of large floating barges with rotating chopping blades (i.e., Swamp Devil) to remove cattails. This technique is costly and relatively invasive. Enhancing muskrat (Ondatra zibethicus) population abundances may be a way to leverage a native biocontrol to set-back T. x glauca expansions. Ben specifically evaluated survival and post-translocation spatial ecology of muskrats (Ondatra zibethicus) to assess if translocation would be a viable management technique. He translocated muskrats into treatment sites to enhance muskrat densities and monitored the subsequent effects on cattail expansions and changes in native biodiversity. Ben received his B.S. in Wildlife Management (with minor in Wetlands Ecology) from Bemidji State University and an M.S. degree in Wildlife and Outdoor Enterprise Management from Kansas State University. His work from our lab is published in Wildlife Biology, Journal of Parasitology, and Journal of Zoo and Wildlife Medicine. Ben is now an Assistant Area Manager with the Minnesota Department of Natural Resources.
Max Larreur
Max quantified the impacts of invasive-hybrid cattails (T. x glauca) on the spatial distribution of semiaquatic mammals (muskrats [Ondatra zibethicus], mink [Neovison vison], and otter [Lontra canadensis]) in lacustrine ecosystems in northern Minnesota, USA. His field work was focused in Voyageurs National Park where he worked closely with park biologists to collect data for his thesis. Max's research will be used to inform cattail management across the Midwest and could provide insight into how expanding T. x glauca populations affect native biodiversity in wetlands across North America. Max received his B.A. degree in Biology from Franklin College in Franklin, Indiana and his M.S. degree in Wildlife and Outdoor Enterprise Management from Kansas State University. His thesis work is published in Landscape Ecology and Wildlife Society Bulletin. Max is now a Ph.D. student at Southern Illinois University where he is focused on the spatial ecology of gray foxes in Illinois (Urocyon cinereoargenteus).
Kyle Wait
Kyle is interested in how land-use change structures carnivore communities. He used camera traps positioned along urban-rural gradients to investigate how urban land use affected the spatial distribution of carnivores in the last remaining tall-grass prairie in North America. He was also interested in how coyotes (Canis latrans), the apex predator in the region, influenced habitat occupancy dynamics of mesocarnivores along urban rural gradients. Kyle received his B.S. and M.S. degree in Wildlife and Outdoor Enterprise Management from Kansas State University. His thesis work is published in Journal of Wildlife Management and Journal of Mammalogy.
Zachary Porterfield
Zach was interested in how accurate waterfowl hunters are at identifying their harvested waterfowl species. Strict waterfowl harvest limits are imposed on some species based on observed abundance trends and harvest quotas. If the ability to identify these species is not accurate, some hunters may over harvest particular species. However, this potential bias in harvest reporting has not been rigorously evaluated. Zach's work will help waterfowl managers identify species-specific biases if they do exist.
Justin Patterson
Justin's work supported our large-scale research project in Voyageurs National Park. He was interested in how encroaching T. x glauca populations, and their subsequent management, affect the diversity and abundance of native crayfish occurring in wetlands in northern Minnesota, USA. Justin evaluated pre- and post-management wetland sites and assessed how the abundance and diversity of crayfish responded to large-scale T. x glauca removal efforts.
Spencer Wesche
Unfortunately, Spencer has never attended Kansas State University. She was an undergraduate student from Franklin College in Indiana and worked on our invasive-hybrid cattail project in Voyageurs National Park as a technician for my graduate student, Max. While working on Max's project, Spencer completed her own research project investigating how common loon habitat selection is affected by expanding invasive-hybrid cattail (T. x glauca) populations. She presented her research at the TWS meeting in Raleigh, NC and she published this work in the Wildlife Society Bulletin. Spencer graduated from Franklin College with a B.A. in Biology and is now a conservation officer in Idaho.
Weiqiang Zhi
Weiqiang was interested in how preferred habitat associations of Earth's mammals factored into species-specific extinction risks. Specifically, he was investigating relative changes in extinction risks for semiaquatic mammals in relation to terrestrial and marine mammals (while controlling for mean body sizes). He used IUCN data to address these questions and presented his work at the Central Plains Society of Mammalogists annual meeting. Weiqiang recently graduated from Kansas State University with a B.S. in Statistics.
Michelle Lefave
Michelle was investigating how canid (e.g., coyote, red fox, and gray fox) harvest data can be used to infer relative population changes. She was using ~30 years of data from Illinois, USA to determine if responses in red fox (Vulpes vulpes) and gray fox (Urocyon cinereoargenteus) harvest was related to increases in coyote (Canis latrans) populations during this time. Michelle has since graduated from Kansas State University with a B.S. in Wildlife and Outdoor Enterprise Management.
