Global climate change (GCC) is projected to bring higher-intensity precipitation and higher-variability temperature regimes to the Northeastern United States. The interactive effects of GCC with anthropogenic land use and land cover changes (LULCCs) are unknown for watershed level hydrological dynamics and nutrient fluxes to freshwater lakes. Increased nutrient fluxes can promote harmful algal blooms, also exacerbated by warmer water temperatures due to GCC. To address the complex interactions of climate, land and humans, we developed a cascading integrated assessment model to test the impacts of GCC and LULCC on the hydrological regime, water temperature, water quality, bloom duration and severity …

The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison

Independent Study Project (ISP) Collection

The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …

Annual Swine Manure Applications To Soybean Under Corn-Soybean Rotation, Allah Bakhsh, Rameshwar S. Kanwar, James L. Baker, John E. Sawyer, Antonio P. Mallarino

John E. Sawyer

The response of a corn-soybean rotation system receiving fall manure application to both corn and soybean is not well understood in terms of its impact on nitrate leaching to subsurface drainage water and crop yields. This field study was conducted from 2001 through 2005 with the key objective of determining the effects of manure application to both corn and soybean on NO3-N concentrations in subsurface drainage water and corn-soybean yields. The study was conducted on 0.4 ha plots instrumented with state-of-the-art subsurface drainage monitoring systems at the Iowa State University research center, Nashua, Iowa. Nitrogen application rates from liquid swine …

Achieving The Sustainable Development Goals: A Case Study Of The Complexity Of Water Quality Health Risks In Malawi, Rochelle Holm, Philip Wandschneider, Allan Felsot, Golden Msilimba

Faculty Scholarship

RESULTS: The water quality data and human dimension questionnaire results were used to develop a household risk presentation. Sixty-seven percent and 50 % of well water and household drinking water samples, respectively, exceeded the WHO health guideline of zero detections of E. coli. Technology transfer was advanced by providing knowledge through household risk debriefing/education, establishing a water quality laboratory at the local university, and providing training to local technicians.

Aquaculture In Shared Waters Fact Sheet: Getting To Know Your Water, Dana Morse, Samuel Belknap, Rebecca Clark Uchenna

Maine Sea Grant Publications

Aquaculture businesses must operate on sound environmental principles, most especially because marine aquaculture occurs in an open system: the ocean. While all farming activities, on land or at sea, have some degree of environmental interaction, farmers should understand these processes, with best management practices to minimize negative impacts. Successful farms must cope effectively with any changes to the marine system, and an organized system of monitoring and recordkeeping will improve your chances of business success, while maintaining a healthy environment. This fact sheet provides a summary of direct and indirect environmental factors that may affect your marine aquaculture business; more …

Access To Groundwater And Link To The Impact On Quality Of Life: A Look At The Past, Present And Future Public Health Needs In Mzimba District, Malawi, R. C.G. Chidya, R. H. Holm, M. Tembo, B. Cole, P. Workneh, J. Kanyama

Faculty Scholarship

Imagine a world where you have to get up at 4am to walk for two hours in the dark to fetch water. This remains true in Malawi, where it is said that the Millennium Development Goals have been met. This research aimed at understanding the impact access to groundwater has on people's ‘Being’, ‘Belonging’ and ‘Becoming,’ as well as on people's capabilities and on their quality of life in Mzimba District, Malawi. Being, Belonging and Becoming define three life domains. Being reveals ‘who one is,’ Belonging reflects ‘connections with one's environments’ and Becoming relates to ‘achieving personal goals, hopes and …

Assessment Of Streamside Management Zones For Conserving Benthic Macroinvertebrate Communities Following Timber Harvest In Eastern Kentucky Headwater Catchments, Joshua K. Adkins, Christopher D. Barton, Scott Grubbs, Jeffrey W. Stringer, Randall K. Kolka

Forestry and Natural Resources Faculty Publications

Headwater streams generally comprise the majority of stream area in a watershed and can have a strong influence on downstream food webs. Our objective was to determine the effect of altering streamside management zone (SMZ) configurations on headwater aquatic insect communities. Timber harvests were implemented within six watersheds in eastern Kentucky. The SMZ configurations varied in width, canopy retention and best management practice (BMP) utilization at the watershed scale. Benthic macroinvertebrate samples collected one year before and four years after harvest indicated few differences among treatments, although post-treatment abundance was elevated in some of the treatment streams relative to the …

Current Status Of Marker Genes Of Bacteroides And Related Taxa For Identifying Sewage Pollution In Environmental Waters, Warish Ahmed, Bridie Hughes, Valerie J. Harwood

Integrative Biology Faculty and Staff Publications

Microbial source tracking (MST) endeavors to determine sources of fecal pollution in environmental waters by capitalizing on the association of certain microorganisms with the gastrointestinal tract and feces of specific animal groups. Several decades of research have shown that bacteria belonging to the gut-associated order Bacteroidales, and particularly the genus Bacteroides, tend to co-evolve with the host, and are, therefore, particularly suitable candidates for MST applications. This review summarizes the current research on MST methods that employ genes belonging to Bacteroidales/Bacteroides as tracers or “markers” of sewage pollution, including known advantages and deficiencies of the many polymerase chain …

Effects Of Environmental Water Rights Purchases On Dissolved Oxygen, Stream Temperature, And Fish Habitat, Nathaniel R. Mouzon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Degraded water quality has reduced aquatic species abundance and survivability in Nevada’s Walker River. Low instream flows and increased nutrients affect native fish populations through high daily stream temperatures and low nightly dissolved oxygen concentrations. Increasing streamflow, through environmental water purchases, may improve water quality and enhance habitat for native fish species, such as Lahontan cutthroat trout. This study uses River Modeling System, a computer model, to estimate streamflows, stream temperatures, and dissolved oxygen concentrations in the Walker River. Streamflow increases are simulated to determine potential improvements to high water temperatures and low dissolved oxygen concentrations, enabling the prioritization of …

Evaluation Of Rusle 2 To Estimate Soil Loss From Pastures, Stasha Katrina Balkissoon

Graduate Theses and Dissertations

The accurate estimation of soil erosion by the Revised Universal Soil Loss Equation version 2 (RUSLE2) is critical for several conservation assessments, least of which is its use in the Phosphorus Index (PI) to identify and rank the vulnerability of agricultural fields to phosphorus (P) runoff. Earlier versions of RUSLE reported a soil loss overestimation, which were revised to give RUSLE2, where biomass production in different climatic regions was more accurately represented. RUSLE version 2.0, which contains the new vegetative biomass production routine, was evaluated using two performance indices, the Nash Sutcliffe Efficiency Index (NSE) and Index of Agreement (D) …
