Dr. Fedy Google Scholar Profile
Over the last 20 years, our ability to use genetic insights to quantify within and between species diversity and understand the underlying mechanisms has greatly increased. This has been facilitated by an increase in computational power, availability of statistical techniques and our ability to genetically characterize individuals and populations. Broadly speaking, my current research interests lie in combining spatial, ecological and genetic techniques to quantify and understand the underpinnings of both neutral and adaptive diversity within and between closely related species. At the University of Waterloo, I will be working with Dr. Brad Fedy to understand the influences of landscape characteristics in driving genetic connectivity between populations of the Greater Sage-Grouse across Wyoming. This work will build on previous research, which has identified seasonal habitat use preferences for this species. Combined this work will contribute to our understanding of sage-grouse ecology and assist with identifying landscape features and regions important for maintaining stable and connected populations.

My primary interests are waterfowl and wetlands. I completed my Master’s at Western University working with Long Point Waterfowl investigating survival and habitat use of wood ducks produced from nest boxes. I completed my honours BSc in Natural Resources Management at the University of Northern British Columbia. I am also generally interested in spatial ecology, and the application of GIS and statistical techniques, to better understand how animal movement and habit use influences fitness. My PhD research at the University of Waterloo is in partnership with Ducks Unlimited Canada. The Western Boreal Forest (WBF) is considered the second most important breeding area for waterfowl in North America; however, changes in habitat caused by timber harvest, oil and gas exploration and extraction, mining, hydroelectric development, and recreation threaten carrying capacity. The goal of my research is to test a top-down hypothesis that landscape change in the WBF is increasing predation rates on waterfowl, because of range expansion of new predator species, increased success rates of native predators, or predator population increases in response to increased alternative prey. Based on my findings, we can then model predation rates at a landscape scale to help identify potential ecological sinks and better inform future conservation efforts in the WBF.
Chris Kirol (PhD)
I received his Bachelor of Science in Biology from another UW, the University of Wyoming, in 2000. After working in a variety of capacities in wildlife research and management, I returned to the University of Wyoming and received a Master of Science in the Ecosystem Science and Managements Department in 2012. My Master’s project focused primarily on predicting Greater Sage-grouse selection and fitness on a landscape scale in an area influenced by energy development and assessing microhabitat vegetation conditions that are most important to female Greater Sage-grouse during the reproductive period in xeric sagebrush habitats. My interests broadly lie in applied research informing science-based wildlife management and conservation planning. To-date my research has focused on the sagebrush-steppe ecosystem and sagebrush obligate avian species such as the sage-grouse. My research has explored sage-grouse habitat at microhabitat and microhabitat (landscape scales) and primarily in human-altered sagebrush landscapes. Specifically, how is habitat quality-the ability of the environment to provide conditions suitable for individual and population persistence compromised by human features and activities, such as oil and gas development, in the sagebrush ecosystems and what can be done better to reduce the impacts of these activates.
Marcus Maddalena (Master’s)
I am returning to the University of Waterloo to pursue a M.E.S, having also completed my B.E.S in the Department of Environment and Resource Studies. My research interests include habitat selection and use by a variety of wildlife populations, with the goal of developing effective management strategies. My undergraduate thesis compared two survey methods for white-tailed deer, and examined factors driving overwinter habitat selection by a Central Ontario population. I am currently working with Parks Canada and the Toronto Zoo to assess the population of Eastern Milksnakes, a species of special concern nationally, within the Greater Toronto Area. The project focuses on the Rouge Valley population of Milksnakes and their movement patterns. With the fragmented state of our urban green spaces, it is important to understand how Milksnakes move through these landscapes to implement effective management strategies. By identifying surrounding populations, we can then examine connectivity and the influence of potential disturbances on habitat selection.
After graduating with a BSc from the University of Waterloo, I decided to work with Bird Studies Canada on a project dedicated to surveying the species richness and abundance of birds on private and public lands while also assessing habitat quality. I’ve been a birder for a few years, but working on that project further emphasized that I wanted to dedicate my career to studying and mitigating the impacts of anthropogenic habitat changes on wildlife populations, with a focus on avian species. In the Fedy Lab, I’m able to combine my passions for habitat reclamation and songbird conservation. Our study site, located in Northeastern Wyoming, is composed of large areas of active oil and gas developments, relatively untouched sagebrush habitat, and reclaimed post-oil and gas development land. This site provides an ideal landscape to assess the songbird richness and abundance, as well as the microhabitat characteristics at nest sites of various sagebrush obligate and associate species across this gradient of development. Ultimately, this research will inform reclamation of vast development landscapes as the oil and gas resources are exhausted and the land is reclaimed. In addition to understanding the ecology of avian systems in sagebrush ecosystems, we also hope to provide relevant information to land managers so they can best conserve, reclaim and protect sagebrush ecosystems.
