Multi-element fingerprinting of waters to evaluate connectivity among depressional wetlands
Establishing the connectivity among depressional wetlands is important for their proper management, conservation and restoration. In this study, the concentrations of 38 elements in surface water and porewater of depressional wetlands were investigated to determine chemical and hydrological connectivity of three hydrological types:...Yuan, Yuxiang; Zhu, Xiaoyan; Mushet, David M.; Otte, Marinus L.
Mortality in Aransas-Wood Buffalo Whooping Cranes: Timing, location, and causes
For long-lived species with low fecundity rates, population growth rate can be sensitive to changes in annual survival. Understanding where, when, and why animals die provides useful information for prioritizing conservation practices designed to increase survival. As part of a satellite tracking study, we identified 19 confirmed and suspected...Pearse, Aaron T.; Brandt, David; Hartup, Barry K.; Bidwell, Mark T.
Revisiting the historic distribution and habitats of the Whooping Crane
The endangered Whooping Crane (Grus americana) historically had a wide distribution that covered diverse ecoregions across North America while retaining consistent habitat preferences within each ecoregion. We reevaluate the historic information compiled by Robert Porter Allen in 1952 and added 74 other records. Based on the ecological...Austin, Jane E.; Hayes, Matthew A.; Barzen, Jeb A.
The 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...McKenna, Owen P.; Mushet, David M.; Scherff, Eric J.; Mclean, Kyle I.; Mills, Christopher T.
Distance models as a tool for modelling detection probability and density of native bumblebees
Effective monitoring of native bee populations requires accurate estimates of population size and relative abundance among habitats. Current bee survey methods, such as netting or pan trapping, may be adequate for a variety of study objectives but are limited by a failure to account for imperfect detection. Biases due to imperfect detection could...McNeil, Darin J.; Otto, Clint R. V.; Moser, Erin L.; Urban-Mead, Katherine R.; King, David E.; Rodewald, Amanda D.; Larkin, Jeffrey L.
Adaptive management in native grasslands managed by the U.S. Fish and Wildlife Service—Implications for grassland birds
Burning and grazing are natural processes in native prairies that also serve as important tools in grassland management to conserve plant diversity, to limit encroachment of woody and invasive plants, and to maintain or improve prairies. Native prairies managed by the U.S. Fish and Wildlife Service (FWS) in the Prairie Pothole Region of the...Igl, Lawrence D.; Newton, Wesley E.; Grant, Todd A.; Dixon, Cami S.

Chapter 13: Terrestrial wetlands
1. The assessment of terrestrial wetland carbon stocks has improved greatly since the First State of the Carbon Cycle Report (CCSP 2007) because of recent national inventories and the development of a U.S. soils database. Terrestrial wetlands in North America encompass an estimated 2.2 million km2, which constitutes about 37% of the global wetland...Kolka, Randall; Trettin, Carl; Tang, Wenwu; Krauss, Ken W.; Bansal, Sheel; Drexler, Judith; Wickland, Kimberly P.; Chimner, Rodney A.; Hogan, Dianna; Pindilli, Emily; Benscoter, Brian; Tangen, Brian; Kane, Evan S.; Bridgham, Scott; Richardson, Curtis
Cranes have a close relationship with arable and pastoral agriculture that goes back hundreds, presumably thousands of years. The landscapes and ecoregions important to cranes are also those areas most conducive to agriculture. Thus, cranes and humans are attracted to the same landscapes and will therefore have futures that remain co-mingled. As...Morrison, Kerryn L.; Austin, Jane E.
Threats to cranes related to agriculture
The greatest threats to cranes worldwide are related to agricultural activities. They include direct losses of wetlands or grasslands; altered wetland hydrology due to water control systems such as dams or irrigation ditches; fire; direct and indirect impacts from agricultural chemicals; human disturbances; disease risks where cranes congregate in...Austin, Jane E.
Methods to reduce conflicts between cranes and farmers
Alternative methods to reduce conflicts between cranes and farmers range from relatively simple, inexpensive disturbance methods to changes in land use at a landscape scale. Visual and acoustics disturbance methods can be useful for small fields or gardens but require frequent changes to prevent habituation by the cranes. Changes in farming...Austin, Jane E.; Sundar, K.
