Biography
Brian Tangen is an Ecologist at the USGS Northern Prairie Wildlife Research Center (NPWRC) in Jamestown, North Dakota. Brian studied aquatic invertebrates in streams and wetlands while working towards bachelor’s and Master’s degrees from Valley City State University and North Dakota State University. He began his professional career processing and identifying aquatic invertebrates and conducting a wide variety of field work for NPWRC’s aquatics lab. Since then he has worked in a variety of roles at NPWRC performing research focused on carbon and greenhouse gas cycling in wetland systems, wetland hydrology, wetland management, and effects of climate- and land-use change.

Status: Active Mechanisms, models, and management of invasive species and soil biogeochemical process in prairie pothole wetlands
The ecological foundation of thousands of acres of wetland habitat is being impacted by changes in land cover, land use, climate, and invasive species. This project utilizes USGS remotely-sensed products, along with experimental and observational field data to develop spatially-explicit, landscape-scale models of invasive cattails and soil biogeochemical processes. These models will assist...

Status: Completed Description of aquatic vegetation and invertebrate communities at Big Stone National Wildlife Refuge
Big Stone National Wildlife Refuge is situated within a riverine system where refuge wetlands receive sediment-laden inflows that have been associated with diminished plant communities and water quality conditions. Accordingly, improved habitat- and water-quality conditions have been recognized as overall management goals, and the collection of baseline biotic and abiotic data has been...

Status: Completed Assessment of pattern tile drainage on wetland hydrology and ecosystem services in the Prairie Pothole Region
Prairie Pothole Region wetlands provide numerous ecological services to society such as wildlife habitat, water storage, and carbon sequestration. Agricultural production in the region has been enhanced through the expanded installation and use of subsurface drainage systems, but these systems may have a negative impact on the region’s wetlands, including those protected by conservation...

Wetland and hydric soils
Soil and the inherent biogeochemical processes in wetlands contrast starkly with those in upland forests and rangelands. The differences stem from extended periods of anoxia, or the lack of oxygen in the soil, that characterize wetland soils; in contrast, upland soils are nearly always oxic. As a result, wetland soil biogeochemistry is...

Soil organic carbon stocks and sequestration rates of inland, freshwater wetlands: Sources of variability and uncertainty
Impacts of land use, specifically soil disturbance, are linked to reductions of soil organic carbon (SOC) stocks. Correspondingly, ecosystem restoration is promoted to sequester SOC to mitigate anthropogenic greenhouse gas emissions, which are exacerbating global climate change. Restored wetlands have relatively high potential to sequester carbon...

A review of Cattail (Typha) invasion in North American wetlands
OverviewCattail (Typha) is an iconic emergent wetland plant found worldwide. By producing an abundance of wind-dispersed seeds, cattail can colonize wetlands across great distances, and its rapid growth rate, large size, and aggressive expansion result in dense stands in a variety of aquatic ecosystems such as marshes, ponds, lakes, and riparian...

Study design and methods for a wetland condition assessment on U.S. Fish and Wildlife Service fee-title lands in the Prairie Pothole Region of North Dakota, South Dakota, and Montana, USA
The U.S. Fish and Wildlife Service (FWS) manages wetlands and grasslands for wildlife habitat throughout the central North American Prairie Pothole Region (PPR). PPR wetlands, or potholes, are widely recognized as critical habitats for North American migratory waterfowl, waterbirds, and other wildlife. Potholes also provide other ecosystem...

Typha (cattail) invasion in North American wetlands: Biology, regional problems, impacts, ecosystem services, and management
Typha is an iconic wetland plant found worldwide. Hybridization and anthropogenic disturbances have resulted in large increases in Typha abundance in wetland ecosystems throughout North America at a cost to native floral and faunal biodiversity. As demonstrated by three regional case studies, Typha is capable of rapidly colonizing habitats and...

Hydrologic lag effects on wetland greenhouse gas fluxes
Hydrologic margins of wetlands are narrow, transient zones between inundated and dry areas. As water levels fluctuate, the dynamic hydrology at margins may impact wetland greenhouse gas (GHG) fluxes that are sensitive to soil saturation. The Prairie Pothole Region of North America consists of millions of seasonally-ponded wetlands that are ideal...

Effects of land use on greenhouse gas flux in playa wetlands and associated watersheds in the High Plains, USA
In the High Plains, U.S., native prairie conversion to cropland agriculture has resulted in a loss of service delivery capabilities from most depressional wetlands as a result of sedimentation. Restoring historic hydrological conditions to affected wetlands may rejuvenate some services, however, there may be tradeoffs due to emissions of CH4 ...

Diurnal patterns of methane flux from a seasonal wetland: mechanisms and methodology
Methane emissions from wetlands are temporally dynamic. Few chamber-based studies have explored diurnal variation in methane flux with high temporal replication. Using an automated sampling system, we measured methane flux every 2.5 to 4 h for 205 diel cycles during three growing seasons (2013–2015) from a seasonal wetland in the Prairie...
