Males And Females Evolve Riskier Traits In Populations With Eavesdropping Parasitoids, Oliver M. Beckers, William E. Wagner

School of Biological Sciences: Faculty Publications

Predation and/or parasitism often limits the evolution of conspicuous male traits and female preferences because conspicuous traits can attract predators or parasites and it is costly for females to associate with males that attract predators or parasites. As a result, males and females in high-risk populations are expected to evolve safer mating behaviors compared to individuals from low-risk populations. We tested this antagonistic selection hypothesis in the field cricket Gryllus lineaticeps. Males produce chirped songs, and both female crickets and the eavesdropping parasitoid fly Ormia ochracea prefer faster chirp rates. The flies attack the field crickets late in the …

Fueling Defense: Effects Of Resources On The Ecology And Evolution Of Tolerance To Parasite Infection, Sarah A. Budischak, Clayton E. Cressler

School of Biological Sciences: Faculty Publications

Resource availability is a key environmental constraint affecting the ecology and evolution of species. Resources have strong effects on disease resistance, but they can also affect the othermain parasite defense strategy, tolerance. A small but growing number of animal studies are beginning to investigate the effects of resources on tolerance phenotypes. Here, we review how resources affect tolerance strategies across animal taxa ranging from fruit flies to frogs to mice. Surprisingly, resources (quality and quantity) can increase or reduce tolerance, dependent upon the particular host-parasite system. To explore this seeming contradiction, we recast predictions of models of sterility tolerance and …

Effect Of Stocking Rate On Growing Juvenile Sunshine Bass, Morone Chrysops × M. Saxatilis, In An Outdoor Biofloc Production System, Bartholomew W. Green, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The biofloc technology production system is a production intensifying management strategy used primarily for culturing tilapia and penaeid shrimp, both of which can consume the biofloc. Other fish can be grown in biofloc systems because the biofloc serves to maintain water quality, metabolizing the ammonia excreted by intensively fed fish. A dose-response study was conducted in an outdoor biofloc system to begin quantifying the stocking rate-production function for sunshine bass, Morone chrysops x M. saxatilis, advanced fingerlings. Sunshine bass (2.9 ± 0.2 g/fish) were stocked into tanks at 50 to 250 fish/m² in 50 fish/m² increments. After …

Assessment Of Total Suspended Solids And Total Phosphorus Removal By Wetlands And Best Management Practices In Lincoln, Nebraska, Deborah Marik

Department of Environmental Studies: Undergraduate Student Theses

The availability and quality of local surface and ground water, as well as water in the world’s oceans is essential to all. Urbanization brings with it changes in landscape that decreases soils capacity for infiltration of rain, and increase contaminants found in runoff conveyed to surface waters including oceans. Stormwater runoff occurs with small to large size rain events, flowing over a diverse range of impermeable surfaces removing and carrying with it total suspended solids (TSS) and total phosphorus (TP). For these reasons, best management practices (BMPs) were developed, and integrated into existing and future development. The objective is to …

A Risk-Based Approach To Evaluate The Impact Of Interventions At Reducing The Risk Of Foodborne Illness Associated With Wheat-Based Products, Luis Sabillon

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

Pathogens are emerging on previously unrecognized food vehicles, such as wheat flour, which is a widely consumed commodity. Despite its low water activity, wheat-based ingredients and products have been implicated in several foodborne outbreaks over the last few years, resulting not only in the recall of food products but also in consumer illnesses. As a raw agricultural commodity, wheat is exposed to naturally occurring microbiological contamination that may compromise the overall safety of flour and other derived products. To address the increased concern regarding the safety of wheat-based foods, the objectives of the present research study were designed to develop …

Motivations, Specializations, Identities, And Constraints Associated With Hunting In Nebraska, Alisha Grams

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

This research herein examines the statewide motivations, specializations, identities, and constraints of Nebraska resident hunters. An online survey was conducted in the fall of 2017 asking respondents about their motivations, skills, demographics, and constraints to personal hunting experiences to determine what factors affect hunters. We used factor analysis to examine the effect of motivations, specializations, and constraints to see which factors influence participation. By understanding multiple attributes of our hunters, we gain further insight into participation trends and recreationists needs and expectations. Results suggested that our biggest constraint to overcome is land access, while most people are motivated to hunt …

Osl Dating Of The Tolleston Beach At Indiana Dunes National Lakeshore And Its Implications For Interpreting The Archaeological Record, Malgorzata Mahoney

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The puzzling scarcity of archaeological sites on the Tolleston Beach, the most lakeward shoreline complex at Indiana Dunes National Lakeshore, prompted an investigation into the development of these parabolic dunes in an attempt to determine whether the distribution of known archaeological sites is governed by ancient human behaviors, or influenced by its dune setting which can affect site preservation and discoverability. In order to accurately understand patterns of past human occupation, it is important to know the timing and extent of dune reactivation. Specifically, whether it was frequent enough to influence settlement patterns in the past, or if it was …

Mind The Gaps: How Can Food Safety Gaps Be Addressed In Developing Nations?, Jessie L. Vipham, Byron D. Chaves, Valentina Trinetta

Department of Food Science and Technology: Faculty Publications

As global food systems integrate, to meet the demands of a growing global population, safe and healthy agriculture value-chains will be essential to maintaining public health worldwide. In many ways, the current global food production landscape is made up of “mice and men.” Meaning that the food sector within and across most countries includes both large-scale corporate agriculture production and varying degrees of small-scale agriculture production; the variation being the interpretation of small scale, which is highly dependent upon the country. This structure presents challenges for the creation of effective food safety systems in many countries, and can contribute to …

Purification And Characterization Of Naturally Occurring Post-Translationally Cleaved Ara H 6, An Allergen That Contributes Substantially To The Allergenic Potency Of Peanut, Govardus A. H. De Jong, Shyamali Jayasena, Philip Johnson, Justin Marsh, Danijela Apostolovic, Marianne Van Hage, Julie A. Nordlee, Joe Baumert, Steve L. Taylor, Camille Roucairol, Harmen De Jongh, Stef J. Koppelman

Department of Food Science and Technology: Faculty Publications

The 2S albumin Ara h 6 is one of the most important peanut allergens. A post-translationally cleaved Ara h 6 (pAra h 6) was purified from Virginia type peanuts, and the cleavage site was mapped using high-resolution mass spectrometry. Compared to intact Ara h 6, pAra h 6 lacks a 5-amino acid stretch, resembling amino acids 43−47 (UniProt accession number Q647G9) in the nonstructured loop. Consequently, pAra h 6 consists of two chains: an N-terminal chain of approximately 5 kDa and a C-terminal chain of approximately 9 kDa, held together by disulfide bonds. Intermediate post-translationally cleaved products, in which this …

Ready For The Robot: Bovines In The Integrated Circuit, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

Situating cows as co-laborers in global technology sectors, “Ready for the Robot” explores the predicament of cows working as robot operators, information workers, and data producers. The data cows produce shape the conditions in which they work, including their own bodies, as statistical evaluations of cattle abstract profitable traits and warp their connection to breed. Milking robots are posited as providing freedom to dairy cows, but this is far from guaranteed. Rather, cow bodies are programmed to fit the limitations of the robot and the routines of the automated farm, coding that breaches categories of breed. Drawing on Donna Haraway’s …

Forage Potential Of Summer Annual Grain Legumes In The Southern Great Plains, Gurjinder S. Baath, Brian K. Northup, Alexandre C. Rocateli, Prasanna H. Gowda, James P. S. Neel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Winter wheat (Triticum aestivum L.) and perennial warm-season grasses are the primary forage resources for grazing yearling stocker cattle (Bos taurus) in the US Southern Great Plains (SGP). However, low nutritive value of perennial grasses during mid to late summer limits high rates of growth by stocker cattle. In response, there has been a continued search for plant materials with the potential to provide forage high in crude protein (CP) and digestibility during August through September. A broad range of under-utilized legume species that are grown as grain crops in Africa, India, and South and Central America may have some …

Marine Threats Overlap Key Foraging Habitat For Two Imperiled Sea Turtle Species In The Gulf Of Mexico, Kristen M. Hart, Autumn R. Iverson, Ikuko Fujisaki, Margaret M. Lamont, David Bucklin, Donna J. Shaver

United States Geological Survey: Staff Publications

Effective management of human activities affecting listed species requires understanding both threats and animal habitat-use patterns. However, the extent of spatial overlap between high-use foraging areas (where multiple marine species congregate) and anthropogenic threats is not well-known. Our modeling approach incorporates data on sea turtle spatial ecology and a suite of threats in the Gulf of Mexico to identify and map “hot spots” of threats to two imperiled turtle species. Of all 820 “high” threats grid cells, our tracked turtles foraged at least 1 day in 77% of them. Although threat data were not available outside the U.S. Exclusive Economic …

Short Communications: First Tracking Of Individual American Robins (Turdus Migratorius) Across Seasons, Alex E. Jahn, Susannah B. Lerman, Laura M. Phillips, Thomas B. Ryder, Emily J. Williams

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The American Robin (Turdus migratorius) is one of the most widespread, common bird species in North America; yet, very little is known about its migratory connectivity, migration timing, and migratory routes. Using archival GPS tags, we tracked the movements of 7 individual robins from 3 breeding populations in the United States. Four robins captured in Denali National Park and Preserve, Alaska, overwintered in Texas, Nebraska, Oklahoma, and Montana, up to 4,500 km from the capture location. One robin captured in Amherst, Massachusetts, overwintered in South Carolina 1,210 km from the capture location, whereas 2 robins captured in Washington, D.C., spent …

Facilitating And Improving Environmental Research Data Repository Interoperability, Corinna Gries, Amber Budden, Christine Laney, Margaret O’Brien, Mark Servilla, Wade Sheldon, Kristin Vanderbilt, Dave Vieglais

Copyright, Fair Use, Scholarly Communication, etc.

Environmental research data repositories provide much needed services for data preservation and data dissemination to diverse communities with domain specific or programmatic data needs and standards. Due to independent development these repositories serve their communities well, but were developed with different technologies, data models and using different ontologies. Hence, the effectiveness and efficiency of these services can be vastly improved if repositories work together adhering to a shared community platform that focuses on the implementation of agreed upon standards and best practices for curation and dissemination of data. Such a community platform drives forward the convergence of technologies and practices …

Acarine Biodiversity In Ecuador: Two New Species Of Endoparasitic Chiggers (Acarina: Trombiculidae) From Terrestrial Andean Anurans, Ricardo Guerrero, Mario Humberto Yánez-Muñoz

MANTER: Journal of Parasite Biodiversity

Two species of endoparasitic chiggers, Vercammenia neotropica n. sp. and Microtrombicula ecuadorensis n. sp., are described, both found in terrestrial anurans of the genus Pristimantis collected in the Andes of Ecuador. A new combination is proposed for Trombicula yorkei Sambon, 1928 as Microtrombicula yorkei (Sambon, 1928) n. comb., and Schoengastia lynni Ewing, 1942 is placed as incertae sedis. This is the first record of species of the genus Vercammenia in the Neotropical region.

Experimental Evaluation Of The Importance Of Colonization History In Early-Life Gut Microbiota Assembly, Inés Martínez, Maria X. Maldonado-Gomez, João Carlos Gomes-Neto, Hatem Kittana, Hua Ding, Robert J. Schmaltz, Payal Joglekar, Roberto Jiménez Cardona, Nathan L Marsteller, Steven W. Kembel, Andrew K. Benson, Daniel A. Peterson, Amanda Ramer-Tait, Jens C. Walter

Department of Food Science and Technology: Faculty Publications

The factors that govern assembly of the gut microbiota are insufficiently understood. Here, we test the hypothesis that inter-individual microbiota variation can arise solely from differences in the order and timing by which the gut is colonized early in life. Experiments in which mice were inoculated in sequence either with two complex seed communities or a cocktail of four bacterial strains and a seed community revealed that colonization order influenced both the outcome of community assembly and the ecological success of individual colonizers. Historical contingency and priority effects also occurred in Rag1^-/- mice, suggesting that the adaptive immune system …

Searching Images And The Meaning Of Alarm Calls, Alan B. Bond

Alan Bond Publications

The snake alarm call of Japanese tits prompts nesting adults to search for and mob the reptile until it is driven away. From playback experiments, Suzuki (2018) has inferred that the call provides an associative cue, evoking a searching image of the salient visual features of the predator—a novel approach to exploring visual attention and vocal communication in the wild.

Comparative Demography Elucidates The Longevity Of Parasitic And Symbiotic Relationships, Luke B.B. Hecht, Peter C. Thompson, Benjamin M. Rosenthal

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Parasitic and symbiotic relationships govern vast nutrient and energy flows, yet controversy surrounds their longevity. Enduring relationships may engender parallel phylogenies among hosts and parasites, but so may ephemeral relationships when parasites colonize related hosts. An understanding of whether symbiont and host populations have grown and contracted in concert would be useful when considering the temporal durability of these relationships. Here, we devised methods to compare demographic histories derived from genomic data. We compared the historical growth of the agent of severe human malaria, Plasmodium falciparum, and its mosquito vector, Anopheles gambiae, to human and primate histories, thereby discerning long-term …

Susceptibility Genes To Plant Viruses, Hernan Garcia-Ruiz

Nebraska Center for Virology: Faculty Publications

Plant viruses use cellular factors and resources to replicate and move. Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that viruses must evade or suppress. Thus, the establishment of infection is genetically determined by the availability of host factors necessary for virus replication and movement and by the balance between plant defense and viral suppression of defense responses. Host factors may have antiviral or proviral activities. Proviral factors condition susceptibility to viruses by participating in processes essential to the virus. Here, we review current advances in the identification and characterization of host factors …
