An Empirical Analysis Of Climatic, Geographic, And Cultural Determinants Of International Tourism, Ethan Straus
An Empirical Analysis Of Climatic, Geographic, And Cultural Determinants Of International Tourism, Ethan Straus
Honors Theses
Each year, billions of people visit different countries all around the world. For many of those countries, tourism is their primary industry, leading to millions of jobs and dollars in revenue. It is expected that by 2020 total International Tourism Receipts will reach 2 trillion US dollars annually. Currently, tourism employs an estimated 200 million people around the world. With the continued progression of climate change, the tourism industry is facing a newfound threat. Global temperatures and the seal level are both expected to rise significantly by the end of the century. Additionally, the Intergovernmental Panel on Climate Change has …
Changes In Wetland Conditions And Wetland Plant Communities In The Prairie Pothole Region After 50 Years, Ryann Cressey
Changes In Wetland Conditions And Wetland Plant Communities In The Prairie Pothole Region After 50 Years, Ryann Cressey
Electronic Theses and Dissertations
Wetlands in Stutsman County, North Dakota were revisited after 50 years to assess changes in wetland conditions and plant communities within wetland zones in the Prairie Pothole Region. In 1961-1966, Robert E. Stewart and Harold A. Kantrud conducted a study to investigate the relationship of wetland plant communities to variations of water permanence and chemistry on three study areas: Crystal Springs, Cottonwood, and Mt. Moriah. Within in this region, a severe drought occurred in 1988- 1992 followed by the longest deluge starting in 1993 with wetlands still impacted today. In 2013 and 2014, I revisited 80 of the original wetlands …
A Quantitative Approach To The Development Of Ecological Sites And State-And-Transition Models, Matthew W. Van Scoyoc
A Quantitative Approach To The Development Of Ecological Sites And State-And-Transition Models, Matthew W. Van Scoyoc
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Changes in land-use and climate can trigger changes in ecosystem conditions and may be driving ecosystems toward undesired “states” that provide inadequate ecosystem services. If these changes are drastic enough, energy intensive restoration programs are necessary to restore ecosystems to previous states. Landscape classification systems based on “ecological potential” offer a robust framework to evaluate and manage ecosystems. The ecological site concept is one such landscape classification system that has been developed by the USDA Natural Resources Conservation Service (NRCS) and describes ecosystems and ecosystem dynamics relative to “reference conditions” and response to disturbance. Ecological sites have gained popularity with …
