Genetic Dissection Of Non-Host Resistance To The Wheat Stem Rust Pathogen, Using An Interspecific Barberry Hybrid, Radhika Bartaula

Doctoral Dissertations

Stem rust, caused by the macrocyclic fungal pathogen P. graminis (Pg), is one of the most devastating diseases of wheat and other small grains globally; and the emergence of new stem rust races virulent on deployed resistance genes brings urgency to the discovery of more durable sources of genetic resistance. Given its intrinsic durability and effectiveness across a broad range of pathogens, non-host resistance (NHR) presents a compelling strategy for achieving long-term rust control in wheat. However, NHR to Pg (Pg-NHR) remains largely unexplored as a protection strategy in wheat, in part due to the challenge of developing a genetically …

The Use Of Mentoring To Effect Cultural Change: Irish Farm Deaths And Injuries, Maurice Murphy, Kieran O'Connell

Dept. of Management & Enterprise Conference Material

Agriculture is the most dangerous occupation in Ireland. For every fatality in the sector, more than 125 farm workers are injured, many of them so seriously that the viability of the farm is undermined. These terrible and largely hidden figures have remained constant for the past decade, despite legal requirements, awareness-raising events and inspections by the Health and Safety Authority (HSA). The agricultural sector accounts for just 6% of the working population of Ireland, yet it consistently has the highest proportion of fatal incidents of any sector. This was again evident in 2017 where 51% (24 of the 47) of …

Fall crops are coming up, and they’re amazing. We started digging up the potatoes today and it is so crazy to see how many potatoes can grow from planting a chunk of potato with a couple of eyes on it! Some of these plants have two pounds of potatoes growing off of them. The pumpkins are already enormous, and the butternut squash are still ripening but are really good-sized already. The melons are taking longer than expected, but look great. Our one warm-season failure seems to be the eggplant- but watch them produce like crazy now that I’ve said that. …

Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer

Entomology Faculty Publications

Elemental data are commonly used to infer plant quality as a resource to herbivores. However, the ubiquity of carbon in biomolecules, the presence of nitrogen-containing plant defensive compounds, and variation in species-specific correlations between nitrogen and plant protein content all limit the accuracy of these inferences. Additionally, research focused on plant and/or herbivore physiology require a level of accuracy that is not achieved using generalized correlations. The methods presented here offer researchers a clear and rapid protocol for directly measuring plant soluble proteins and digestible carbohydrates, the two plant macronutrients most closely tied to animal physiological performance. The protocols combine …

Systemic Behaviour Change: Irish Farm Deaths And Injuries, Maurice Murphy, Kieran O'Connell

Dept. of Management & Enterprise Conference Material

While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year. This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector. Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to be fatally injured in a farm accident than the general …

Integrating Socio-Environmental Models: Vegetation, Agriculture, And Landform Dynamics, Miguel Acevedo, William Boyd, Hessam Sarjoughian, Isaac Ullah, Michael Barton

International Congress on Environmental Modelling and Software

How did landscapes evolve as agriculture emerged thousands of year ago? How do we ensure sustainable food production and still maintain environmental quality? Integrated socio-environmental models help provide answers to these two seemingly distant, yet related questions. For practical purposes, in this paper we use the terms socio-ecological and socio-environmental systems, with acronym SES as synonyms. The Mediterranean Landscape Dynamics (MedLand) project aims to develop experimental SES models made possible by recent advances in computation while exercising interdisciplinary collaboration. In this paper, we exemplify one aspect of this integration by discussing the development of a vegetation model, which at the …

Romania -- Systematic Country Diagnostic: Background Note-Agriculture (English), Edinaldo Tebaldi, Anatol Gobjila

Economics Faculty Journal Articles

Agriculture plays a significant socio-economic role in Romania and its transformation to a modern, vibrant, and market-oriented sector is central to fighting poverty, promoting social inclusion, and reducing the urban/rural development divide. Most of Romania's poor live in rural areas and earn their living from agriculture or agriculture-related activities. In 2016, eight out of ten people who were at risk of poverty or social exclusion lived either in rural areas or in towns and suburbs that were predominately rural. Using microdata from the 2013 Household Budget Survey (HBS), this report finds that individuals living in rural areas are 16.5 percent …

Subsidizing Climate Change: How The Agricultural Business Is Harming Our Planet, Caroline Berejka

Student Theses 2015-Present

In exploring the concept of environmental sustainability in the modern age, it is important to look at the practices of the agriculture industry and the role of agricultural production in the multifaceted issue of climate change. The agriculture industry's overwhelming power in the US government and its resistance to moving toward more sustainable practices is an issue that the average American has little awareness of. In order to push the movement of environmental sustainability forward, it is necessary to examine the economic reasons for the slow shift towards sustainable agriculture and possible incentives for industrial farmers to modify their practices. …

Spatiotemporal Dynamics Of Multi-Scale Habitat Selection In An Invasive Generalist, Kelsey Elizabeth Paolini

Theses and Dissertations

Spatiotemporal dynamics of resource availability can produce markedly different patterns of landscape utilization which necessitates studying habitat selection across biologically relevant extents. Feral pigs (Sus scrofa) are a prolifically expanding, generalist species and researchers have yet to understand fundamental drivers of space use in agricultural landscapes within the United States. To study multi-scale habitat selection patterns, I deployed 13 GPS collars on feral pigs within the Mississippi Alluvial Valley. I estimated resource selection using mixed-effects models to determine how feral pigs responded to changes in forage availability and incorporated those results with autocorrelated kernel density home range estimates. My results …
