In the Northern Great Plains (NGP), the combined impacts of land-use and climate variability have the potential to place many soils on the tipping point of sustainability. The objectives of this study were to assess if the conversion of grassland to croplands occurred on fragile landscapes in the North America Northern Great Plains. South Dakota and Nebraska were selected for this study because they are located in a climate transition zone. We visually classified 43,200 and 38,400 points in South Dakota and Nebraska, respectively, from high-resolution imagery in 2006, 2012, and 2014 into five different categories (cropland, grassland, habitat, NonAg, …

Students will conduct hands-on experiments to see how greenhouse gases interact with the Earth’s atmosphere and how greenhouse gases affect temperature. This lesson introduces National Geographic’s Geo-Inquiry Process, where students will identify a Geo-inquiry question, collect data, and create a project around the answer to their question. Students will then present their findings to their peers and evaluate their Geo-Inquiry process.

In this teaching module, students will explore emerald ash borer (EAB), its impacts on the ash trees, and how warming temperatures could affect EAB populations. The emerald ash borer is a green buprestid or jewel beetle native to north-eastern Asia that causes devastating disease in ash trees.


Effects Of Grazing And Fire On Soil Microbial Communities And Hydrological Processes In The Northern Great Plains Grassland, Jacob Comer Jan 2019

Effects Of Grazing And Fire On Soil Microbial Communities And Hydrological Processes In The Northern Great Plains Grassland, Jacob Comer

Electronic Theses and Dissertations

Historic grazing and fire regimes have been altered with the development of the livestock industry in the Northern Great Plains and have resulted in a reduction of diversity across all scales. As alternative land surface disturbances are developed to combat the loss of diversity, their potential to serve as a sustainable land surface disturbance should be evaluated. To determine the ability of an alternative grazing strategy to serve as a sustainable land surface disturbance, the reaction of the soil microbial community and soil hydrological processes should be evaluated. Objectives of this study were to: 1) evaluate the impact of alternative …
