Resilience Of Working Agricultural Landscapes, Shana Sundstrom, Jennifer Hodbod, Craig R. Allen

School of Natural Resources: Faculty Publications

Many alternative agricultural approaches have been developed as a response to the social and ecological costs of modern industrialized agriculture. These include diversified, organic, sustainably intensified, and ecologically intensified farming systems, each of which addresses different aspects of agriculture as a social-ecological system. However, clear theoretical models that account for human-nature coupling and the importance of scale are lacking. Global change, including climate change, land use change, and other human activities influencing social-ecological systems, is exacerbating uncertainty regarding agriculture system dynamics and increasing the need for comprehensive models that include a dynamical integration of socio-ecological-economic influences. Resilience theory and related …

Remnant Prairies And High-Diversity Restorations Work Together To Support Wild Bees Season-Long, Katie Lamke, David A. Wedin, Judy Wu-Smart

School of Natural Resources: Faculty Publications

The presence of diverse bee communities in an ecosystem is vital for maintaining healthy plant communities, promoting habitat resilience, and supporting agriculture. In the US, wild bee declines have led to increased monitoring efforts, but there remain critical data gaps in much of the Midwest. Here, we sought to examine how variation in richness and abundance of flowering forbs influences the richness and abundance of wild bees across “remnant” tallgrass prairies, “high diversity” prairie restorations, and “low diversity” prairie restorations or degraded grasslands in eastern Nebraska. High-diversity plots attracted no bees in the early season due to a lack of …

Polycentric Governance In Nebraska, U.S., For Ground And Surface Water, Theresa Jedd, Anthony B. Schutz, Mark Burbach

School of Natural Resources: Faculty Publications

This chapter describes the locally driven, but centrally coordinated, water governance model in Nebraska, U.S. It offers a snapshot of water resources and the importance of agriculture, then moves to the relevant political institutions in the state, and federal controls related to water quantity. The focus of the chapter is on the Nebraska Department of Natural Resources’ (NeDNR) and Natural Resources Districts’ (NRDs) management of surface and groundwater, which has some distinct and some overlapping authority. The main area of overlap is in addressing the connection between ground and surface water, particularly in situations when either or both are over …

A Greenhouse Gas Emissions Inventory For Nebraska: Livestock And Coal Loom Large, Eric R. Holley, Adam Liska

Adam Liska Papers

Mitigation of climate change requires the systematic identification and cataloging of emissions sources at city, state, and national levels. In this study, an inventory of annual greenhouse gas emissions from the state of Nebraska was created based on industry data, and emissions inventories were completed each year from 1990 to 2016. Nebraska’s net emissions were found to increase from 56.2 million metric tons of carbon dioxide equivalents (MMtCO₂e) in 1990 to 87.4 MMtCO₂e in 2016. Agriculture was found to be the sector with the most emissions (36 MMtCO₂e) followed by electricity generation (21 MMtCO …

Invasive Plants Watch List: 2022, Allison Zach

Nebraska Invasive Species Program

The purpose of the weed watch list is to collect data on the distribution of invasive plants found in various Nebraska counties. Counties were divided up into ‘ecoregions’ based on the Nebraska Game & Parks Commission’s Legacy Plan (map of regions below). The plants in the watch list have been identified based on their invasiveness in surrounding states and their increasing range in Nebraska. Data collected on watch list plant species distribution has been used to support the listing or delisting of noxious weeds. Plant species in the weed watch list are categorized based on early detection and rapid response …

Laborem Exercens And The Subjective Dimension Of Work In Economics And Finance, Geoffrey Frieson

Department of Finance: Faculty Publications

The objective dimension of work involves the person acting on external objects through the process of economic production. But because persons tend toward self-realization, and because work is an integral part of this process, the person is also the subject of work. The subjective dimension of work involves work as a creative process operating on the person performing the work. In the encyclical Laborem Exercens, John Paul II argues that the subjective dimension of work is primary and that the primary basis of the value of work is the subject: man himself. This does not mean that the economic …

Toddler Play Preferences And The Teacher’S Role In The Outdoor Play Environment, Keting Chen, Erin E. Hamel

Department of Child, Youth, and Family Studies: Faculty Publications

Direct experience with nature is a primary component of environmental education and especially beneficial for young children. The present study examined the outdoor play preferences of toddlers and investigated the role teachers play in the outdoor space. Toddlers’ outdoor play was video recorded by GoPro cameras and coded for preferred play locations and initiator of the play. Results showed that the three most preferred spaces for toddlers in the outdoor classroom were the sandbox, swing area, and play structures; least frequently visited were open areas close to the classrooms, the garden, and the tree area. In addition, toddlers initiated play …

Towards Water Literacy: An Interdisciplinary Analysis Of Standards For Teaching And Learning About Humans And Water, Silvia‑Jessica Mostacedo‑Marasovic, Brooke Colleen Mott, Holly White, Cory T. Forbes

School of Natural Resources: Faculty Publications

Water is critical to sustain human existence. Water literacy involves understanding the interactions within and between natural and human dimensions of water systems to support informed decision-making, an important outcome for learners of all ages. It is therefore critical to foster water literacy in today’s global citizens, particularly through formal education. The purpose of this study, in tandem with a parallel study focusing on natural dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for teaching and learning about human dimensions of water systems to develop a comprehensive and transdisciplinary perspective on water education. …

Seasonal Variation In Terrestrial Invertebrate Subsidies To Tropical Streams And Implications For The Feeding Ecology Of Hart’S Rivulus (Anablepsoides Hartii), David C. Owens, Thomas N. Heatherly, Kent M. Eskridge, Colden V. Baxter, Steven A. Thomas

Department of Statistics: Faculty Publications

Terrestrial invertebrates are important subsidies to fish diets, though their seasonal dynamics and importance to tropical stream consumers are particularly understudied. In this year-round study of terrestrial invertebrate input to two Trinidadian headwater streams with different forest canopy densities, we sought to (a) measure the mass and composition of terrestrial inputs with fall-in traps to evaluate the influences of seasonality, canopy cover, and rainfall intensity, and; (b) compare terrestrial and benthic prey importance to Anablepsoides hartii(Hart’s Rivulus), the dominant invertivorous fish in these streams, by concurrently measuring benthic and drifting invertebrate standing stocks and the volume and composition of …

Genome-Wide Association Study Of Disease Resilience Traits From A Natural Polymicrobial Disease Challenge Model In Pigs Identifies The Importance Of The Major Histocompatibility Complex Region, Jian Cheng, Rohan Fernando, Hao Cheng, Stephen D. Kachman, Kyusang Lim, John C.S. Harding, Michael K. Dyck, Frederic Fortin, Graham S. Plastow, Piggen Canada Research Consortium, Jack C.M. Dekkers

Department of Statistics: Faculty Publications

Infectious diseases cause tremendous financial losses in the pork industry, emphasizing the importance of disease resilience, which is the ability of an animal to maintain performance under disease. Previously, a natural polymicrobial disease challenge model was established, in which pigs were challenged in the late nursery phase by multiple pathogens to maximize expression of genetic differences in disease resilience. Genetic analysis found that performance traits in this model, including growth rate, feed and water intake, and carcass traits, as well as clinical disease phenotypes, were heritable and could be selected for to increase disease resilience of pigs. The objectives of …

Network Science: Ecology, Worlds Of Connections Sepa

Building a network using wooden blocks demonstrates that some pieces in a network are more important than others. Removing pieces of a network will change the structure, but removing the pieces that are most connected or more foundational to the network will have more significant impacts on the network. In an ecosystem network, the more connected the network, the more robust it is. Think about ecosystems and food webs as networks with varying degrees of robustness depending upon how many connections and kinds of connections they contain (e.g. if there are “hubs” or “key links” in the chain). In an …

Network Science: Genealogy, Worlds Of Connections Sepa

Worlds of Connections Resources

Remember that family trees are a type of network. The network we create helps us understand which traits were passed down and who they came from. While humans can inherit traits like hair color and eye shape, sometimes they can inherit genetic diseases or be more likely to develop health issues because of their genetics. In most cases, inherited traits are based on probability, so tracing family networks can tell us how likely people are to have these types of diseases. When tracing the genealogical flow of relatedness from one generation to the next one or two generations, it is …

New Orleans in 1878 was the most exotic and cosmopolitan city in North America. An international port, with more than 200,000 inhabitants, it was open to French, Spanish, Mexican, South American, and West Indian cultural influences, and home to a thriving population descended from free African Americans. It was also a battleground in the fight against yellow fever (malaria) and in the political upheavals that followed the end of Reconstruction. The continued influx of Anglo-Americans and the renewed ascendancy of white supremacists threatened to overwhelm the local blend of languages, races, and cultures that enlivened the unique Creole character of …

Fddm1 And Fddm2, Two Sgs3-Like Proteins, Function As A Complex To Affect Dna Methylation In Arabidopsis, Shengjun Li, Weilong Yang, Yunfeng Liu, Guangyong Li, Xiang Liu, Yaling Liu, James R. Alfano, Chi Zhang, Bin Yu

Center for Plant Science Innovation: Faculty Publications

DNA methylation is an important epigenetic modification required for the specific regulation of gene expression and the maintenance of genome stability in plants and animals. However, the mechanism of DNA demethylation remains largely unknown. Here, we show that two SGS3-like proteins, FACTOR OF DNA DEMETHYLATION 1 (FDDM1) and FDDM2, negatively affect the DNA methylation levels at ROS1-dependend DNA loci in Arabidopsis. FDDM1 binds dsRNAs with 50 overhangs through its XS (rice gene X and SGS3) domain and forms a heterodimer with FDDM2 through its XH (rice gene X Homology) domain. A lack of FDDM1 or FDDM2 increased DNA methylation levels …
