Balancing Interests In Forest Governance In Brazil And Indonesia, Annabel Mccormick Baldy

Environment and Sustainability Honors Papers

Forests play a major role in reducing levels of Greenhouse gasses which are a major contributor to global warming. Conversely, deforestation is a major contributor to climate change. This study examines the concept of good forest governance, dispelling notions that resource use needs to be a zero-sum game. Rather, it identifies local collective agreements as espoused by Elinor Ostrom in Governing the Commons as the best means of balancing the undeniable economic potential of converting forests to other uses (grazing, farming, and mining) with the more sustainable approach of protecting forests for their environmental benefit. For Ostrom, these collective agreements …

Phosphours Trasnport In Soil: Locating And Identifying A Limiting Element, Jeremy Giannone

2023 Midwest Ecology & Evolution Conference

The phosphorus (P) cycle is not well understood. While carbon (C) and nitrogen (N) have gas phases, P does not. Phosphorus runoff in waterways and its shortage are both understood since their causes are due to agricultural demands. Fertilizers increase the rate of phosphorus in the soil leading to greater runoff which then accumulates in the surrounding bodies of water.¹ From an economic perspective the phosphorus availability and food prices have a direct correlation. The instability of phosphate prices may have direct causation to the instability of the food and agriculture markets.²In order to deal with these …

Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely

Independent Study Project (ISP) Collection

Researching food-systems in Nepal can feel like drinking from a fire hydrant. Sixty-six percent of the population is directly involved in agriculture and a diverse set of ecocultural understandings influence the practice across the country’s landscapes, ranging from the Himalayas to urban centers to southern plains. In the Kathmandu Valley and peripheral hills where I conducted my research, seemingly any spare land was under cultivation, enabled by fertile ground, optimal climate, and market potential. But despite the prevalence of farming in daily life throughout the country, Nepal’s food system is not domestically self-sufficient. A complex web of imports and exports …

A Plea For Scale, And Why It Matters For Invasive Species Management, Biodiversity And Conservation, Nicholas A. Mcmillan, Samuel D. Fuhlendorf, Craig A. Davis, Robert G. Hamilton, Landon. K. Neumann, Samantha M. Cady

Department of Agronomy and Horticulture: Faculty Publications

1. Invasive species are suspected to be major contributors to biodiversity declines worldwide. Counterintuitively, however, invasive species effects are likely scale dependent and are hypothesized to be positively related to biodiversity at large spatial scales. Past studies investigating the effect of invasion on biodiversity have been mostly conducted at small scales (<100 m²) that cannot represent large dynamic landscapes by design. Therefore, replicated experimental evidence supporting a negative effect of invasive plants on biodiversity is lacking across many landscape types, including large grasslands.

2. We collected data across eight large (333–809 ha) grassland landscapes managed with pyric herbivory—that is the recoupling …

Large And Stable Genome Edits At The Sorghum Alpha Kafirin Locus Result In Changes In Chromatin Accessibility And Globally Increased Expression Of Genes Encoding Lysine Enrichment, J. Preston Hurst, Abou Yobi, Aixia Li, Shirley Sato, Thomas E. Clemente, Ruthie Angelovici

Department of Agronomy and Horticulture: Faculty Publications

Introduction: Sorghum is a resilient and widely cultivated grain crop used for feed and food. However, it’s grain is deficient in lysine, an essential amino acid. This is due to the primary seed storage proteins, the alpha-kafirins, lacking lysine. It has been observed that reductions in alpha-kafirin protein results in rebalancing of the seed proteome and a corresponding increase in non-kafirin proteins which leads to an increased lysine content. However, the mechanisms underlying proteome rebalancing are unclear. This study characterizes a previously developed gene edited sorghum line, with deletions at the alpha kafirin locus.

Extension Publications

Global food shortages are caused mainly by drought, the primary driver of yield loss in agriculture worldwide. Drought stress negatively impacts the physiological and morphological characteristics of rice (Oryza sativa L.), limiting the plant productivity and hence the economy of global rice production. Physiological changes due to drought stress in rice include constrained cell division and elongation, stomatal closure, loss of turgor adjustment, reduced photosynthesis, and lower yields. Morphological changes include inhibition of seed germination, reduced tillers, early maturity, and reduced biomass. In addition, drought stress leads to a metabolic alteration by increasing the buildup of …
