Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites. Although previous research demonstrates the negative impact of red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) on northern bobwhites, the mechanisms underlying this effect are largely unknown. To meet the protein demands of early growth and development, bobwhite chicks predominantly consume small insects, of which ants are …

Quantifying Spatial Scaling Patterns And Their Local And Regional Correlates In Headwater Streams: Implications For Resilience, Emma Göthe, Leonard Sandin, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. We use explicit spatial modeling to evaluate within- and cross-scale redundancy in headwater streams, an ecosystem type with a hierarchical and dendritic network structure. We assessed the cross-scale distribution of functional feeding groups of benthic invertebrates in Swedish headwater streams during two seasons. We evaluated functional metrics, i.e., Shannon diversity, richness, and evenness, and the degree of redundancy within and across modeled spatial scales for individual feeding groups. We also estimated the correlates of environmental versus spatial factors …

Capacitively Coupled And Direct-Current Resistivity Surveys Of Selected Reaches Of Cozad, Thirty-Mile, Orchard-Alfalfa, Kearney, And Outlet Canals In Nebraska, 2012-13, Christopher M. Hobza, Bethany L. Burton, Jeffrey E. Lucius, Ryan E. Tompkins

United States Geological Survey: Water Reports and Publications

Understanding the spatial characteristics of leakage from canals is critical to effectively managing and utilizing water resources for irrigation and hydroelectric purposes. Canal leakage in some parts of Nebraska is the primary source of water for groundwater recharge and helps maintain the base flow of streams. Because surface-water supplies depend on the streamflow of the Platte River and the available water stored in upstream reservoirs, water managers seek to minimize conveyance losses, which can include canal leakage. The United States Geological Survey, in cooperation with the Central Platte Natural Resources District and Nebraska Public Power District, used capacitively coupled (CC) …

Study On Investment In Water And Wastewater Infrastructure And Economic Development, Edward J. Collins, Jr. Center For Public Management, University Of Massachusetts Boston

Edward J. Collins Center for Public Management Publications

The Edward J. Collins, Jr. Center for Public Management in the John W. McCormack Graduate School of Policy and Global Studies at the University of Massachusetts Boston was tasked by the Massachusetts Water Resources Authority Advisory Board (MWRAAB) with asking and answering a very fundamental question relating to public infrastructure: “What is the relationship between investment in water and wastewater infrastructure and economic growth?” To do so, Center staff not only researched the positive results of investing in infrastructure, but also took time to consider what failing to invest in adequate water and wastewater infrastructure might mean. Additionally, the Center …

The Potential Release Of Phosphorus In Floodplains, Maria S. Rossetti, Nicole K. Ownby, Erin Scott, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

In the Illinois River Watershed, there has been growing concern over elevated phosphorus concentrations in the water column. This study evaluated how much phosphorus is contributed from floodplain soils into surface waters, examining the relationship between the flux of phosphorus released and the amount of phosphorus stored in the soil. This was investigated by artificially inundating soil cores from four sites and determining the soluble reactive phosphorus concentrations of the overlying water and the levels of Water and Mehlich-3 extractable phosphorus in the soil. The flux of phosphorus to the overlying water ranged from 0.43 to 6.61 mg m-2 hr-1 …

Reducing Water Extractable Phosphorus In Poultry Litter Using Chitosan Treatment, Zachary Simpson, Brina Smith, David A. Zaharoff, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus (P) is an important factor in the eutrophication of freshwater, and watershed sources include effluent discharges and the landscape. Poultry litter applied to the landscape can be a potential source of P, which is dependent on rainfall, runoff and dissolution. Chitosan, the deacetylated form of the biopolymer chitin, has been shown to have an effect on reducing water extractable phosphorus (WEP) in poultry litter when applied as a powder. The intent of this study was to measure the effect that poultry litter treatment (PLT), acetic acid and incubation time have on chitosan’s ability to reduce WEP in poultry litter. …

Remote Sensing With Computational Intelligence Modelling For Monitoring The Ecosystem State And Hydraulic Pattern In A Constructed Wetland, Golam Mohiuddin

Electronic Theses and Dissertations

Monitoring the heterogeneous aquatic environment such as the Stormwater Treatment Areas (STAs) located at the northeast of the Everglades is extremely important in understanding the land processes of the constructed wetland in its capacity to remove nutrient. Direct monitoring and measurements of ecosystem evolution and changing velocities at every single part of the STA are not always feasible. Integrated remote sensing, monitoring, and modeling technique can be a state-of-the-art tool to estimate the spatial and temporal distributions of flow velocity regimes and ecological functioning in such dynamic aquatic environments. In this presentation, comparison between four computational intelligence models including Extreme …

A Continuous Hydrologic Model Structure For Applications At Multiple Time Scales, Jonathan Griffen

Electronic Theses and Dissertations

There are many different controlling factors on the partitioning of rainfall into runoff. However, the influence of each of these controls varies across different temporal scales. Consequently, numerous water balance models have been developed in the literature for application across various time scales. These models are usually developed for a particular time scale so that the controls with the greatest influence on rainfall partitioning are captured. For example, the SCS curve number method was developed to simulate direct runoff at the event scale; the "abcd" model was developed as a monthly water balance model; and the Budyko model was developed …

Winter Survival Strategies Of Benthic Invertebrates In Temporary Habitats In A Northern Minnesota Lake, Cal Oldenburg

Journal of Earth and Life Science

During the winter months in the northern hemisphere, above 40 degrees latitude, a freezing event occurs that can last several months. Some lakes may have large portions of the shallow littoral zone frozen completely solid down into the sediments. Invertebrates affected by these events have developed survival strategies to cope with the harsh environment. The two main strategies for invertebrates in these areas are to either migrate to a different area and recolonize the original area when it becomes available again, or to burrow into the sediments and withstand the freezing. A 1- month study took place on Lake Bemidji …

Application Of Ce-Qual-W2 On Tigris River In Iraq, Muhanned Al-Murib

Osmb Final Report: Task 3. Containment Strategies For Eurasian Watermilfoil Infested Central Or Lakes, Vanessa Morgan, Mark Sytsma

Center for Lakes and Reservoirs Publications and Presentations

In recent years, public awareness of aquatic invasive species (AIS) has increased considerably in Oregon and elsewhere in the western U.S.. News articles, boat inspection stations and AIS permit programs have drawn attention to the threat of aquatic invasive species, especially animals like zebra mussels (Dreissena polymorpha), quagga mussels (Dreissena bugensis), and New Zealand mudsnails (Potamopyrgus antipodarum). However, invasive aquatic plants are also capable of causing severe impacts and may similarly be transferred between waterbodies on boats, trailers or other equipment. Heavy infestations can hinder recreational use by motorized and non-motorized boats, snag fishing lines, threaten the safety of swimmers …

Participant Impacts From A Participatory Water Modeling Workshop In The Sonora River Basin, Mexico, David J. Kossak

Dissertations, Master's Theses and Master's Reports - Open

Much of the research in the field of participatory modeling (PM) has focused on the developed world. Few cases are focused on developing regions, and even fewer on Latin American developing countries. The work that has been done in Latin America has often involved water management, often specifically involving water users, and has not focused on the decision making stage of the policy cycle. Little work has been done to measure the effect PM may have on the perceptions and beliefs of decision makers. In fact, throughout the field of PM, very few attempts have been made to quantitatively measure …

Domestic Wells, Paul Bossert, Sarah Armstrong

Water Matters!

The domestic well statutes direct that the State Engineer “shall” issue a permit for certain types of temporary or low volume wells, including wells for household use. For the past fifty-five years, the Office of the State Engineer (OSE) has interpreted this to mean that such permits are granted with no evaluation, public notice, or hearing.

Taos Pueblo Water Rights Settlement, Paul Bossert, Darcy S. Bushnell

Water Matters!

In November of 2010, the Congress passed the Claims Resolution Act and on December 8, President Obama signed it into law. Title V of the Claims Act, the Taos Pueblo Indian Water Rights Settlement Act, settles the Pueblo portion of the Abeyta case and approves an agreement signed in 2006 by officials from Taos Pueblo, the State of New Mexico, and other interested water rights owners in the Taos area. The settlement act also helps resolve the non-Indian portion of Abeyta. The measure quantifies Taos Pueblo’s water rights and protects the interests of local acequias, the Town of Taos, and …

Effects Of Toxic Cyanobacteria (Microcystis Aeruginosa) On The Feeding And Reproduction Ecology Of The Copepod Eurytemora Affinis From Green Bay, Lake Michigan, Nicholas J. Barrett

Lawrence University Honors Projects

Toxic Cyanobacteria is known to be a bad food source to consumers as well as a main contributor to harmful algal blooms. This study investigates the feeding relationship between an invasive copepod in the Great Lakes system, Eurytemora affinis, and a toxic strain of cyanobacteria, Microcystis aeruginosa. E.affinis has been shown to feed on toxic cyanobacteria. By measuring the filtering rate, ingestion rate, egg production and offspring size between three different food conditions, we hope to gain insight into the effects of toxic cyanobacteria on the feeding and reproduction of this copepod. Food sources include a good green algal …
