The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales

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

Nebraska’s agricultural landscapes are rapidly changing, affecting natural resources and their successful management. I utilized two surveys and scenario planning (Chapters 1: statewide survey, 2: local survey, and 3: scenario-planning workshop) to investigate attitudes and perceptions of natural resource management and cross-boundary collaboration. My first objective focused on determining what prevents Nebraskans from addressing natural resources challenges, considering demographics amongst generations and the type of areas they live in (rural versus urban). The second objective focused on whether landowners engaged with their community in managing natural resources. The third objective was to develop alternative future scenarios for the Denton Hills …

Fall Field Report, August–November 2023, W. Ross Silcock

Nebraska Bird Review

As in the last few fall seasons, late departure dates continue to increase in number. This is often attributed to a warming climate but may also result from increased observer activity and usage of eBird. Late dates are probably the most important aspect of this report, most prominent the record late fall dates for Ruby-throated Hummingbird, Sanderling, Bank Swallow, and Cassin’s Sparrow. Although these species are taxonomically diverse, there were species group concentrations of late dates, notably among shorebirds. Examples were Marbled Godwit for which the four latest reports this fall were four of the latest six fall dates on …

Can The Vegetation Structure And Composition In Urban Green Spaces Determine Diversity Of Green Lacewings (Neuroptera: Chrysopidae)?, Jose I. Martinez, Raiza J. Castillo, Adrián Ardila-Camacho, Charles V. Covell, José Isabel López-Arroyo, Francisco Javier Nava-Guízar

Insecta Mundi

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens …

Genomics-Based Taxonomic Rearrangement Of Achlyodini And Carcharodini (Lepidoptera: Hesperiidae: Pyrginae), Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

Insecta Mundi

Genomic analysis of Pyrginae Burmeister, 1878 (Lepidoptera: Hesperiidae Latreille, 1809) with an emphasis on the tribes Achlyodini Burmeister, 1878 and Carcharodini Verity, 1940 reveals many incon­sistencies between the resulting phylogeny and the current classification. These problems are corrected by proposing new taxa, changing the ranks of others, or synonymizing them, and transferring species between genera. As a result, five subtribes, one genus, 20 subgenera, and one species are proposed as new: Cyclo­semiina Grishin, new subtribe (type genus Cyclosemia Mabille, 1878), Ilianina Grishin, new subtribe (type genus Iliana E. Bell, 1937), Nisoniadina Grishin, new subtribe (type genus Nisoniades Hübner, [1819]), …

Defensive Behaviors Of The Mealybug Nipaecoccus Nipae (Maskell, 1893) (Hemiptera: Pseudococcidae) And The Green Lacewing Ceraeochrysa Claveri (Navás, 1911) (Neuroptera: Chrysopidae), With Videos Of Dorsal Packet Loading And Mealybug Ostiole Function, Erin C. Powell

Insecta Mundi

The interactions between the lacewing Ceraeochrysa claveri (Navás) (Neuroptera: Chrysopidae) larva and the coconut mealybug Nipaecoccus nipae (Maskell) (Hemiptera: Pseudococcidae) were recorded. The third-instar lacewing larva constructed a dorsal packet using mealybug wax from both male pupal cases and the bodies of adult females. Surprisingly, live nymphs were also frequently placed into the dorsal packet. Prey mealybugs were discarded and not incorporated into the packet after consumption. When disturbed, adult female mealybugs reflex bled from their dorsal ostioles, contacting the mouthparts of the lacewing. The lacewing quickly retreated to clean the mouthparts on the substrate, providing further evidence that ostiolar …

Predicting The Potential Distribution In South Korea Of Two Mealybug Species (Hemiptera: Pseudococcidae) Intercepted On Pineapples In Quarantine, S Bin Kim, Soo-Jung Suh

Insecta Mundi

Dysmicoccus brevipes (Cockerell) and Dysmicoccus neobrevipes Beardsley are major pests of pine­apples, ornamentals, and vegetable crops in many countries around the world. The potential distribution of these mealybug pests into South Korea remains a prime concern because of their high incidence in intercep­tions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s is projected based on the RCP …

Nou Founding Ornithologist, Hypnotist, Physician: Isador Trostler, Rick Wright

Nebraska Bird Review

Eminent radiologist Benjamin H. Orndoff, eulogizing an esteemed colleague some months after his death, noted that Isador Simon Trostler (1869–1957) “as a lad . . . became interested in ornithology and herpetology, sending accounts of his observations and explorations to natural history magazines up to the late [18]90s.” Understandably more interested in Trostler’s role as a “pioneer in radiology,” Orndoff had no more to say about the natural history pursuits of one of Nebraska’s most notable early ornithologists, one of the founders 125 years ago of the Nebraska Ornithologists’ Union.

Conversely, we birders have known little or nothing of Trostler’s …

Social Connections Across Migration: Do Golden- Crowned Sparrows (Zonotrichia Atricapilla) That Socialize In Winter Also Breed Together?, Theadora A. Block, Bruce E. Lyon, Zachary Milakonis, Alexis S. Chaine, Daizaburo Shizuka

School of Biological Sciences: Faculty Publications

Many birds that are territorial in the breeding season live in groups during the nonbreeding season, thereby gaining benefits such as protection from predators and increased access to resources. However, how the social connections in group life change across seasons in migratory animals is mostly unknown. We ask whether winter social connections continue during the breeding season in a migratory songbird. Golden-crowned Sparrows (Zonotrichia atricapilla) have distinct, stable winter communities that include both site and group fidelity across years: birds almost always rejoin the same social community each year after migration. If these birds have social connectivity across …

United States Department of Agriculture Wildlife Services: Staff Publications

Highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b underwent an explosive geographic expansion in 2021 among wild birds and domestic poultry across Asia, Europe, and Africa. By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of …

High Throughput Phenotyping: Field Based Triticale Breeding And Educational Resource Impact, Catherine Kay Mick

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Triticale (Triticosecale) is a multifunctional hybrid cereal crop that adopted the hardiness of rye and wheat's high-yielding and nutritional qualities. Plant breeding programs work to improve the quality and number of varieties available to producers through multiple rounds of evaluation and selection. However, traditional phenotyping methods are labor-intensive, time-consuming, and destructive, creating a phenotyping bottleneck. Remote sensing using unmanned aerial systems has the potential to alleviate this issue and change the evaluation of phenotypes in a breeding. Demand for educational resources to advance public awareness and prepare the workforce has increased with the utilization of more technology in …

Vulnerabilities Of Greater Prairie Chicken And Tier 1 At-Risk Species In Nebraska Caused By Grassland Transition To Woody Dominance, Robert Peterson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Woody plant encroachment is a global threat and has been transitioning grasslands to woody dominance at a biome scale. This threat is present in the Great Plains grassland biome which is currently experiencing grassland biome collapse as the alternative woody biome advances northwest. Nebraska, which contains the most intact temperate grassland in the world, is currently at the front lines of this large-scale transition making this state’s management decisions vital for the remaining grasslands and the species which rely on these ecosystems. In this study, we assess the vulnerability of Greater Prairie Chicken and Tier 1 at-risk species in Nebraska …

The benefit of unmanned aircraft systems and image processing methods in agronomic research across numerous crops has been well documented as has the importance of wheat, Triticum aestivum L., on the global food supply. Hence there is great interest in digital solutions applied to aspects of wheat breeding. A major trait of importance to winter wheat breeders in higher latitudes is winter survival, which can result in poor yield and performance if lines do not survive extreme cold. Scoring winter survival is most commonly based on visual score of 0% to 100% with the higher percentage conveying higher winter survival …

Enhancing Urban Water Quality Through Biological-Chemical Treatment: Aquatic Macroinvertebrate Community And Temporal Chlorophyll-A Response, Matthew Chaffee

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

With a growing human population, urbanization is impeding a plethora of natural waterways. Of these, urban ponds play a vital role in nutrient sequestration, flood prevention, and habitat sanctuaries. However, nutrient loading can reduce habitat effectiveness and promote harmful algae blooms. To reduce internal nutrient loads, a biological-chemical treatment strategy consisting of floating treatment wetlands (FTWs) and lanthanum were applied to two urban retention ponds, Densmore and Wilderness Ridge Ponds. To measure effectiveness, chlorophyll-a samples were collected and correlated with Sentinel-2. A novel band algorithm termed 3BR1 produced a strong correlation (R² = 0.72) to physical chlorophyll-a …

Responses Of Maize To Different Irrigation Regimes In Semi-Arid Western Nebraska, Swathi Palle

Development Of An Intact Mass Spectrometry Method For The Detection And Differentiation Of Major Bovine Milk Proteins, Emily F. Harley-Dowell

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The authentication of products with claims regarding protein sources or compositions is a challenge for traditional analytical methods, which generally lack the required specificity whole protein analysis can provide. For example, the establishment of milk as “A2” is achieved through genetic testing of cows before milk production, with no methods to authenticate milk products themselves. Establishment of A2 milk is completed through genetic testing of the cows before milk production, but with no methods to authenticate the milk products themselves. Intact protein mass spectrometry (MS) has the potential to directly authenticate protein products, including specific proteoform claims. The development of …
