Owen McKenna, PhD
Owen P. McKenna is a Research Ecologist at the USGS Northern Prairie Wildlife Research Center in Jamestown, North Dakota. He is currently a Visiting Scientist with the Midwest Climate Adaptation Science Center.
His research is focused studying how changes in climate and land use can alter the hydrology and geochemistry of prairie-pothole wetlands. Dr. McKenna has explored a regional climate-induced ecohydrological state shift in wetland ecosystems through analysis of long-term data. He also helped in development and application of the Pothole Hydrology Linked Systems Simulator (PHyLiSS), which is an integrated hydro-geochemical model for prairie pothole wetlands. Dr. McKenna is currently using PHyLiSS to assist land managers in estimating the future impacts of climate and land-use change on critical migratory waterfowl habitat. Additionally, Dr. McKenna is using the APEX model to integrate prairie-pothole wetlands into U.S. Department of Agriculture conservation planning efforts.

Synergistic interaction of climate and land-use drivers alter the function of North American, Prairie-pothole Wetlands
Prairie-pothole wetlands provide the critical habitat necessary for supporting North American migratory waterfowl populations. However, climate and land-use change threaten the sustainability of these wetland ecosystems. Very few experiments and analyses have been designed to investigate the relative impacts of climate and land-use change drivers, as well as the antagonistic or synergistic interacAuthorsOwen P. McKenna, Samuel Richard Kucia, David M. Mushet, Michael J. Anteau, Mark T. WiltermuthClimate-driven state shifts in the Prairie Pothole Region: Assessing future impacts relevant to the management of wetland habitats critical to waterfowl
Embedded within the North American Prairie Pothole Region (PPR) are millions of small, depressional wetlands that annually support 50–80% of the continent’s waterfowl production. We recently assembled evidence that demonstrates a change towards a wetter climate that is driving a shift in the state of the region’s wetland ecosystems. This ecological state-shift has been primarily the result of a suAuthorsDavid M. Mushet, Owen P. McKennaThe Pothole Hydrology-Linked Systems Simulator (PHyLiSS)—Development and application of a systems model for prairie-pothole wetlands
The North American Prairie Pothole Region covers about 770,000 square kilometers of the United States and Canada (including parts of 5 States and 3 provinces: North Dakota, South Dakota, Montana, Minnesota, Iowa, Saskatchewan, Manitoba, and Alberta). The Laurentide Ice Sheet shaped the landscape of the region about 12,000 to 14,000 years ago. The retreat of the ice sheet left behind low-permeabiliAuthorsOwen P. McKenna, David M. Mushet, Eric J. Scherff, Kyle McLean, Christopher T. MillsAccommodating state shifts within the conceptual framework of the wetland continuum
The Wetland Continuum is a conceptual framework that facilitates the interpretation of biological studies of wetland ecosystems. Recently summarized evidence documenting how a multi-decadal wet period has influenced aspects of wetland, lake and stream systems in the southern prairie-pothole region of North America has revealed the potential for wetlands to shift among alternate states. We proposeAuthorsDavid M. Mushet, Owen P. McKenna, James W. LaBaugh, Ned H. Euliss, Donald O. RosenberryEvidence for a climate-induced ecohydrological state shift in wetland ecosystems of the southern Prairie Pothole Region
Changing magnitude, frequency, and timing of precipitation can influence aquatic-system hydrological, geochemical, and biological processes, in some cases resulting in system-wide shifts to an alternate state. Since the early 1990s, the southern Prairie Pothole Region has been subjected to an extended period of increased wetness resulting in marked changes to aquatic systems defining this region.AuthorsOwen P.
