An Assessment of Annual Forages to Extend Grazing for Beef Cattle in South Central North Dakota
(North Dakota State University, 2015)
This study was designed to test 3 grazing treatments using 2 cropping systems during
2012 to 2014. Angus crossbred beef heifers in mid-gestation were assigned to treatments from
mid-October to late November or early December. ...
Oviposition Preference and Larval Host Range of the Sugarbeet Root Maggot
(North Dakota State University, 2012)
The sugarbeet root maggot, Tetanops myopaeformis Röder, is native to North America; however, its main crop host, sugarbeet, Beta vulgaris L., was introduced to the continent from Europe. This study involved an investigation ...
Climate Change throughout the Dakotas
(North Dakota State University, 2016)
How is the climate changing on a county level throughout North Dakota (ND)
and South Dakota (SD)? To determine this answer, 13 different climate variables
were analyzed: temperature minimums and maximums, precipitation, ...
Restoration of Upland and Riparian Vegetation Communities in the Sheyenne River Valley
(North Dakota State University, 2014)
Degraded rangelands and riparian woodlands in eastern North Dakota are increasing in frequency. Two studies were conducted to address reduced forage quantity and quality and reduced regeneration of riparian tree and shrub ...
A Comparison of Rangeland Monitoring Techniques for Relative Species Abundance in Northern Mixed Grass Prairie
(North Dakota State University, 2014)
Clipping by species is one of the most accurate methods available for determining species composition. However, cost and time constraints often make clipping by species impractical on any large scale. Our objective was to ...
Impact of Rogun Dam on Downstream Uzbekistan Agriculture
(North Dakota State University, 2011)
Strains among the states of Central Asia caused by overuse of the region’s scarce water resources have been increasing in recent years. This is especially true for the relations between Tajikistan, upstream, and Uzbekistan, ...
Community Dynamics of Grassland Birds, Rangeland Vegetation, and Black-Tailed Prairie Dogs on Grazed Mixed-Grass Prairie
(North Dakota State University, 2015)
Investigators surveyed vegetation and grassland bird communities on and off black-tailed prairie dog (Cynomys ludovicianus) towns to investigate community drivers, interactions, and species associations. This study was ...
Crop and Prairie Grasses Serving as Hosts for the Hessian Fly
(North Dakota State University, 2012)
Insect herbivores typically parasitize a relatively small number of plant species. Host specialization is presumed to be a result of evolutionary arms races, with insect adaptations ultimately restricting host range. Being ...
Foraging Ecology of Rangeland Bats
(North Dakota State University, 2017)
Land-use and land cover changes impact the distribution of landscape features in rangelands and wildlife use of the landscape. To balance the requirements of wildlife groups that respond differently to landscape features, ...
The Use of Sediment Removal to Reduce Phosphorus Levels in Wetland Soils and the Distribution of Plant-Available Phosphorus in Wetland Soils and its Potential Use as a Metric in Wetland Assessment Methods
(North Dakota State University, 2014)
Plant-available phosphorus (P) in wetland soils and its relationship with wetland communities and condition is somewhat unknown in the Prairie Pothole Region (PPR) in North America. Research objectives were to determine ...
