The Effects of Abiotic Climate Change Factors on Aphid Life History and Populations
(North Dakota State University, 2015)
While the effects of many abiotic factors associated with climate change have not been extensively studied, work on model organisms is beginning to help predict effects on similar species. Research on climate change has ...
Laboratory and Greenhouse Evaluation of FeEddha Fertilizers of Differing Quality
(North Dakota State University, 2013)
Commercial iron ethylene diamine di(hydroxyl phenyl acetic acid) (FeEDDHA) fertilizers containing the same Fe percent and applied at the same FeEDDHA rate control Fe deficiency chlorosis (IDC) differently due to differing ...
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 ...
