Livestock Producers' Perceptions Of The American Black Vulture Conflict In The Midwestern United States, Marian L. Wahl, Brooke Mcwherter, Patrick A. Zollner, Zhao Ma, Grant C. Burcham, Lee A. Humberg, Brian M. Kluever
Livestock Producers' Perceptions Of The American Black Vulture Conflict In The Midwestern United States, Marian L. Wahl, Brooke Mcwherter, Patrick A. Zollner, Zhao Ma, Grant C. Burcham, Lee A. Humberg, Brian M. Kluever

Human‐wildlife interactions are present wherever both humans and wildlife are found. Interactions can be positive or negative for humans and can include impacts that range from damage to property, agriculture, health and human safety, to emotional effects. Livestock‐wildlife interactions form a major component of human‐wildlife conflicts with foci often centered on the implications of livestock predation by wildlife. While most vulture species are obligate scavengers, several species, including the American black vulture (Coragyps atratus), may attack weak or newborn livestock. Black vulture populations and distributions are expanding in the Midwestern U.S., and attacks create a novel problem for …
Developing Regional Extension Programs And Research Tools For Beekeepers, Sheldon Brummel
Developing Regional Extension Programs And Research Tools For Beekeepers, Sheldon Brummel
Department of Entomology: Dissertations, Theses, and Student Research
The body of work presented in this thesis describes the development and structure of the Regional Great Plains Master Beekeeping training program, which started in 2019, serves 1500+ beekeepers across five Midwest states (IA, KS, MO, NE, WY), and is supported through local partnerships and beekeepers. This chapter also discusses the leadership structure and aspects I developed for program advancement and long-term sustainability, such as incorporating mentorship and volunteer service goals as well as requiring independent projects to become a certified Master beekeeper. Independent projects may focus on research or teaching goals but must illustrate the candidate’s ability to apply …
Parasitism Of Adult Pentatomidae By Tachinidae In Soybean In The North Central Region Of The United Statespheylan, Pheylan A. Anderson, Daniela T. Pezzini, Nádia M. Bueno, Christina D.

Stink bugs (Hemiptera: Pentatomidae) are agricultural pests of increasing significance in the North Central Region of the United States, posing a threat to major crops such as soybean. Biological control can reduce the need for insecticides to manage these pests, but the parasitism of stink bugs byTachinidae (Diptera) is poorly characterized in this region. The objective of this study was to evaluate the rate of parasitism of stink bugs by tachinids over 2 yr from nine states across the North Central Region. Parasitism was assessed by quantifying tachinid eggs on the integument of stink bug adults. Parasitism rates (i.e., percent …
Modeling Gross Primary Production Of Midwest Maize And Soybean Croplands With Satellite And Gridded Weather Data, Gunnar Malek-Madani
Modeling Gross Primary Production Of Midwest Maize And Soybean Croplands With Satellite And Gridded Weather Data, Gunnar Malek-Madani
Department of Geography: Dissertations, Theses, and Student Research
The gross primary production (GPP) metric is useful in determining trends in the terrestrial carbon cycle. Models that determine GPP utilizing the light use efficiency (LUE) approach in conjunction with biophysical parameters that account for local weather conditions and crop specific factors are beneficial in that they combine the accuracy of the biophysical model with the versatility of the LUE model. One such model developed using in situ data was adapted to operate with remote sensing derived leaf area index (LAI) data and gridded weather datasets. The model, known as the Light Use Efficiency GPP Model (EGM), uses a four …
G96-1302 Managing Varroa In The Midwest, Marion D. Ellis, Frederick P. Baxendale
G96-1302 Managing Varroa In The Midwest, Marion D. Ellis, Frederick P. Baxendale
University of Nebraska-Lincoln Extension: Historical Materials
There are important regional differences in varroa population dynamics and control. This NebGuide offers recommendations on varroa management for beekeepers in the Midwest.
Varroa management has become an essential aspect of successful beekeeping since the mite was first discovered in the United States in 1987. Unlike most parasites which coexist with their host, varroa eventually destroy honey bee colonies of European descent. A good understanding of this important bee parasite is essential for successful beekeeping.
Rp367 Strategies For Feeding The Ewe Flock, R.M. Jordan
Rp367 Strategies For Feeding The Ewe Flock, R.M. Jordan
University of Nebraska-Lincoln Extension: Historical Materials
This publication covers the strategies of feeding the ewe flock from aspects to consider and problems likely to be encountered, useful feed consumption data, characteristics of feedstuffs for sheep, pastures, mineral deficiencies and toxicities, and feeding the ewe.
Rp375 Angora Goats In The Midwest, R. M. Jordan
Rp375 Angora Goats In The Midwest, R. M. Jordan
University of Nebraska-Lincoln Extension: Historical Materials
Angora goats and the mohair they produce are not major agricultural products in the United States and certainly not in Minnesota where there are fewer than 3,000 Angora goats. Flocks are small and often are owned by those interested in hand weaving. Nevertheless, mohair finds a ready market. In 1989, raw mohair prices in Texas were: kid hair (it's much finer), $6.50/lb; yearling hair, $2.00/lb; and adult hair, $1.00/lb. In addition, mohair incentive payments have amounted to $30 to $15 per head the past two years. These high hair prices are stimulating interest in goat production among an increasing number …
Differential Effects Of Technological Change On Midwestern Agriculture, Allen C. Wellman
Differential Effects Of Technological Change On Midwestern Agriculture, Allen C. Wellman
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The first objective of this study is to estimate the direct and indirect effects of several specific technological changes related to farm production and subsequent marketing activities on inter-area aspects of income per farm operator, land values, farm size and general adjustments in the competitive strength of states and regions, primarily in the Midwest. The second objective is to assess the research and policy implications of the results of the first objective.
Annual Fodder And Silage Crops For Nebraska, W. E. Lyness, T. A. Kiesselbach
Annual Fodder And Silage Crops For Nebraska, W. E. Lyness, T. A. Kiesselbach
Nebraska Agricultural Experiment Station: Historical Circulars
The present shortage in the seed supply of all standard varieties of annual forage crops has created a special demand for information concerning their relative productivity and the possible use of substitute crops. This circular reports the yields secured from such crops at the Experiment Station, in an effort to help farmers reach a decision as to which crops should be grown this year for roughage, and which ones especially should have their seed supply increased for use in future years. Feed value and production costs as well as yields should be taken into consideration by the grower.
