Participatory Research Workshop On Seasonal Prediction Of Hydroclimatic Extremes In The Greater Horn Of Africa, Tsegaye Tadesse, Deborah Bathke, Nicole Wall, Jacob Petr, Tonya Haigh

Drought Mitigation Center: Faculty Publications

Sixty participants, including experts from seven countries from the Greater Horn of Africa (GHA) and project coinvestigators from the United States, met to discuss seasonal prediction of hydroclimatic extremes across the GHA, engage decision-makers in the assessment of information requirements, and use feedback to orient prediction models to address user needs. Perceptions of current climate change impacts in the GHA were assessed using pre- and postworkshop surveys. Participatory research was conducted through small group discussions on water, agriculture, impacts, and data sharing.

The Status Of Fishes In The Missouri River, Nebraska: Emerald Shiner (Notropis Atherinoides), Red Shiner (Cyprinella Lutrensis), River Shiner (N. Blennius), Sand Shiner N. Stramineus), Spotfin Shiner (C. Spiloptera), Thad W. Huenemann, Kirk D. Steffensen, Gerald Mestl, Dane A. Shuman, Sam Stukel

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Despite major anthropogenic modification to the Missouri River system, relative abundance of five shiner species within Nebraska’s reach of the Missouri River has increased since the 1940’s. The combined abundance of five species: Red Shiner Cyprinella lutrensis, Spotfin Shiner C. spilopterus, Emerald Shiner Notropis atherinoides, River Shiner N. blennius, Sand Shiner N. stramineus, represented > 50% of the small fish community in the Missouri River over the past ten years (2003-2012). More than 3,600 mini-fyke nets were deployed, resulting in over 158,600 shiners collected from the Missouri River along Nebraska’s eastern border between 2003 and 2012. Past literature …

Blow-Up Of Positive Solutions To Wave Equations In High Space Dimensions, Mohammad A. Rammaha, Hiroyuki Takamura, Hiroshi Uesaka, Kyouhei Wakasa

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

This paper is concerned with the Cauchy problem for the semilinear wave equation:

utt - u = F(u) in Rn X [0;1);

where the space dimension n >2, F(u) = jujp or F(u) = up-1u with p>1. Here, the Cauchy data are non-zero and non-compactly supported. Our results on the blow-up of positive radial solutions (not necessarily radial in low dimensions n=2,3) generalize and extend the results of Takamura [19] for zero initial position and Takamura, Uesaka and Wakasa [21] for zero intitial velocity. The main technical difficulty in the paper lies in obtaining the lower bounds for for …

Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie

School of Natural Resources: Dissertations, Theses, and Student Research

Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered the wetland landscape in both …

Genetic And Morphological Variation In Ecuadorian Astroblepid Catfishes, Katherine M. Lawry

School of Natural Resources: Dissertations, Theses, and Student Research

The Andean ichthyofauna remains a poorly understood component of Neotropical biodiversity, and stands in stark contrast to the lowland ichthyofauna in terms of number of species and range of distribution. The Climate Variability Hypothesis (CVH) predicts rapid turnover of species along elevational gradients in tropical climates, but it remains unclear whether stream fishes follow this pattern. Astroblepid catfishes represent a distinctive assemblage of species that inhabit high elevation streams throughout the Andes from Panama to Bolivia, and constitute the only native fish family present in the Ecuadorian highland region. In this research, population samples of Astroblepids collected throughout Ecuador’s Napo …

Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This dissertation consists of three essays. The first essay examines the impact of the 2012 drought and the biofuels mandate on the U.S. grain and livestock markets. A stochastic equilibrium displacement model is used to analyze the impact on eight commodity markets viz. beef, pork, poultry, corn, distillers’ grain (DG), soybean, soymeal, and ethanol. Among the eight markets, corn and beef are found to be the most vulnerable to drought. The use of Renewable Identification Number (RIN) credits as an instrument to mitigate the impact of drought has limited effectiveness. A mandate waiver of about 23% is required to fully …
