Larger Price Limits For Cattle Futures Contracts: Should We Pay Attention To That?, Fabio Mattos

Cornhusker Economics

The CME Group has recently announced an increase in price limits for its cattle futures contracts. This means that cattle futures prices now have a wider range to fluctuate on any given day, and the possibility of larger price fluctuations implies that traders may find larger gains as well as larger losses in their trading accounts at the end of the day. This is certainly something that people trading in futures markets should be aware of, but the change in price limits itself is just a regular update that happens every year. Let's take a closer look at this.

Aspen Impedes Wildfire Spread In Southwestern United States Landscapes, Matthew P. Harris, Jonathan D. Coop, Jared A. Balik, Jessika R. Mcfarland, Sean A. Parks, Camille S. Stevens-Rumann

Aspen Bibliography

Aspen (Populus tremuloides) forests are generally thought to impede fire spread, yet the extent of this effect is not well quantified in relation to other vegetation types. We examined the influence of aspen cover on interpolated daily fire spread rates, the relative abundance of aspen at fire perimeters versus burn interiors, and whether these relationships shifted under more fire-conducive atmospheric conditions. Our study incorporated 314 fires occurring between 2001 and 2020 in the southwestern United States and a suite of gridded vegetation, topography, and fire weather predictor variables. We found that aspen slows fire progression: as aspen cover …

Western Australia’S Agricultural R&D Ecosystem, Ross Kingwell

Farm Systems and Economics published reports

• Decades ago, the agricultural R&D ecosystem in Western Australia (WA) was fairly simple with few funders and some key providers of R&D services such as the Department of Agriculture, CSIRO and the University of Western Australia.
• Since then, the agricultural R&D ecosystem in WA has increased in complexity with more R&D providers and a greater injection of industry and private funding.
• These changes have occurred against a backdrop of the total investment in agricultural R&D declining as a share of agriculture’s gross value of production.
• State and federal governments have reduced their share of the total investment in agricultural R&D. …

Evaluating The Effects Of Row Spacing, Legume Intercropping, Fertilizer Source, And Fertilizer Timing On Intermediate Wheatgrass In Eastern Nebraska, Madeline M. Johnston

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

Kernza^® is the trademarked name of the perennial crop intermediate wheatgrass (Thinopyrum intermedium). In addition to its potential for dual-use as a grain and forage crop, Kernza is marketed to provide needed environmental services by increasing crop biodiversity, sequestering soil carbon, and reducing nitrate leaching. However, more work is needed in cultivar selection and crop management to increase total grain yields and prevent long-term grain yield decline. Furthermore, research in quantifying and understanding Kernza’s ability to affect soil properties and water dynamics is limited.

The Effects Of Extreme Weather On Rural Transportation Infrastructure And Crop Prices Along The Lower Mississippi River, James Mitchell, Hunter D. Biram

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices. This paper estimates the cost of these drought events by analyzing Arkansas soybean basis data and Mississippi River stream gauge data. Low river levels significantly weaken soybean prices, with the impact being a function of a grain market's distance to a river port. Findings have implications for public policy investment in rural infrastructure and risk management …

Bite By Bite: How Ungulate Browsing Shapes North America's Forest Future, Darius Hardalau, Vladut Stefanescu, Mindaugas Bakševičius, Michael Manton, Charles Ruffner, Gediminas Brazaitis, Georgeta Ionescu, Ovidiu Ionescu

Aspen Bibliography

Ungulate browsing represents a contemporary issue for forest development, influencing forest regeneration, composition, and management practices across the world, especially in North America. This review synthesizes findings from 101 studies conducted between 1980 and 2025 to examine patterns of herbivory damage through browsing by moose, elk, white-tailed deer, black-tailed deer, and bison. Despite regional variation, high ungulate density consistently emerges as the primary factor driving browsing intensity and ecological and economic impact, leading to decreased social acceptance of coexistence with ungulates. This review highlights the selective suppression of palatable species such as balsam fir, red oak, and white cedar, leading …

Digital Infrastructure For The Regenerative Movement: A Case Study Of The Mycelium Learning Network, Abigail Karparis

Journal of Nonprofit Innovation

The regenerative movement is gaining momentum worldwide, driven by communities working to restore ecological and social systems through place-based, culturally rooted action. Yet many of the groups leading this work, especially in the Global South or in hyper-local contexts, remain digitally invisible due to structural barriers, including limited access to appropriate technology, funding constraints, and misalignment between available tools and local values. Conventional digital infrastructures often exclude or marginalize these efforts, leaving regenerative practitioners disconnected from each other and from potential sources of support.

This article explores these challenges and presents a case study response: the co-creation of accessible, relational …

Political Agroecology In Syracuse: Local Understandings, Possibilities, And Barriers To Food System Transformation, Cooper Olds

Theses - ALL

In recent years, agroecology has begun to receive increasing attention from international institutions such as the United Nations Food and Agriculture Organization (UN FAO). For some, this is seen as a valuable case of up-scaling agroecology which will lead to greater institutional support for the framework. However, critical agroecologists have raised concerns that such institutional adoption is rather a form of co-optation where the social and political elements of agroecology are omitted to facilitate the integration of the framework into a wider program of food system reform. As a result, there is ongoing contestation over the framework between these co-opted …

The Effects Of Tea Polyphenols On The Emulsifying And Gelling Properties Of Minced Lamb After Repeated Freeze–Thaw Cycles, Xueyan Yun, Ganqi Yang, Limin Li, Ying Wu, Xujin Yang, Aiwu Gao

Agricultural and Environmental Sciences Faculty Research

Minced lamb remains one of the most produced meat products in the meat industry, across both the food service and retail sectors. Tea polyphenols (TPs), renowned for their diverse biological activities, are increasingly being employed as natural food additives in research and development. Tea polyphenols at concentrations of 0.00% (CG), 0.01% (TP1), 0.10% (TP2), and 0.30% (TP3) were added to lamb which had undergone a series of freeze–thaw cycles. The presence of tea polyphenols led to a significant decrease in the number of disulfide bonds, resulting in a slower oxidation rate. In addition, the surface hydrophobicity and juice loss of …
