Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson May 2022

Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson

Biological Sciences Undergraduate Honors Theses

Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized.

Using the root-phenotyping platform RhizoVision Explorer, several root traits of soybean plants treated ...

Climate Change And Conservation Of Milkweed: Evidence Of Extensive Admixture Between Common Milkweed And Poke Milkweed, Elizabeth Davies May 2022

Climate Change And Conservation Of Milkweed: Evidence Of Extensive Admixture Between Common Milkweed And Poke Milkweed, Elizabeth Davies

Undergraduate Honors Theses

Global climate change can drive many changes in species interactions. One primary way it affects species is by changing climates, causing species to expand their ranges and allowing them to interact with species from whom they were previously isolated. In plants, new species interactions can result in hybridization – the creation of hybrid offspring between two separate species. This hybridization can increase gene flow between the species and lead to introgression, the transfer of genetic material from one species to another through hybrid backcrossing with the parent species. My thesis investigates hybridization in the model system Asclepias (milkweed) by analyzing phenotypic ...

Understanding the dynamics of peatland methane (CH4) emissions and quantifying sources of uncertainty in estimating peatland CH4 emissions are critical for mitigating climate change. The relative contributions of CH4 emission pathways through ebullition, plant-mediated transport, and diffusion, together with their different transport rates and vulnerability to oxidation, determine the quantity of CH4 to be oxidized before leaving the soil. Notwithstanding their importance, the relative contributions of the emission pathways are highly uncertain. In particular, the ebullition process is more uncertain and can lead to large uncertainties in modeled CH4 emissions. To improve model simulations of ...

In light of this positioning, it is proposed that the programs work together to build a comprehensive ...


Sustainable Development And The Transformation Of Female Rural Labor: The Case Of Woman Cattle Ranchers In Uruguay, Virginia Courdin Mar 2022

Sustainable Development And The Transformation Of Female Rural Labor: The Case Of Woman Cattle Ranchers In Uruguay, Virginia Courdin

International Grassland Congress Proceedings

Internationally, rural women are considered key to sustainable development. However, in the Uruguayan livestock sector, women’s work is largely unrecognized by public policy makers, causing younger women to migrate, and resulting in the "masculinization" of livestock husbandry. In Uruguay, extensive livestock production (range livestock) analysis has historically ignored the genuinely productive role that women play in rangelands, limiting the visibility of their action to reproductive activities while ignoring their importance in terms of income generation, herd management, networking, strategic planning, etc. Although family production integrates women, their work is often invisible, subsumed within domestic chores or seen as "helping ...

Biodiversity Conservation And Sustainable Livelihoods In Rangelands: Trends, Challenges And Opportunities, J. Waithaka

International Grassland Congress Proceedings

Rangelands cover about 54% of the earth’s surface and are essential for agricultural and livestock production, environmental protection and the in-situ conservation of genetic resources. Despite providing services that support life on earth, rangelands have been neglected to a large extent when compared to other types of ecosystems. This paper provides an overview of the importance of rangelands in conserving biodiversity and supporting the livelihoods of millions of people globally. Rangelands have lost ecological integrity due to unsustainable anthropogenic land-use changes and impacts. It is estimated that over 80% of Key Biodiversity Areas (KBAs) are either not adequately protected ...

Feasibility Of Organic Certification Of Sheep And Goats Produced In Pastoral Systems In Northern Kenya, F. Von Steimker, H. T. Wario, B. Kaufmann

International Grassland Congress Proceedings

In pastoral systems of Kenya, sale of small ruminants is the main regular income source for most households. Although the meat of small ruminants produced in Marsabit county is preferred in the domestic market, no mechanisms are in place that allow for a respective price differentiation. Establishing value chains for labelled sheep and goat meat would be an option to allow pastoralists to profit from their high process and product quality. The aim of the current study is to assess the requirements and feasibility to establish a value chain for labelled products (e.g. origin labelled, organic certified) together with ...

Sustainable Intensification In Crop-Livestock Systems, P. Rovira, Paulo C. De F. Carvalho, J. Terra, F. Lattanzi, R. Pizzio, W. Ayala

International Grassland Congress Proceedings

Extensive livestock production is the main animal source food system in the Pampas and Campos sub-regions in South America. Beef cattle and sheep convert forage biomass that humans cannot eat into nutrient-dense human-edible foods (meat and milk) and valuable co-products (wool). However, diverse global pressures are acting on Pampas systems including increasing demand for protein sources (food security), climate change, environmental footprint, and competition for land. The integration of small areas of pasture-crop rotations is an alternative for increasing efficiency and sustainable intensification of agroecosystems based on natural grasslands. Rotations led by improved pastures increase the carrying capacity and productivity ...

The Comparative Effects Of Short Duration, High Density And Conventional, Rotational Grazing On Different Soil, Vegetation And Animal Parameters In Dry And Mesic Grasslands Of South Africa, Jamie Paulse, Paul Malan, Nico Smit Mar 2022

The Comparative Effects Of Short Duration, High Density And Conventional, Rotational Grazing On Different Soil, Vegetation And Animal Parameters In Dry And Mesic Grasslands Of South Africa, Jamie Paulse, Paul Malan, Nico Smit

International Grassland Congress Proceedings

Short duration, high density grazing is a grazing management strategy that incorporates the rotation of large livestock herds, often at double or triple the normal prescribed stocking densities of the specific area. It is claimed that this type of grazing management can improve rangeland health by improving soil and vegetation condition, and subsequently influencing animal performance. Regardless of the scarcity of scientific evidence validating these claims, the change from conventional rotational grazing systems to short duration, high density grazing systems is on the increase in South Africa. This study aims to assess these claims, through the quantification of various rangeland ...

International Grassland Congress Proceedings

Invasive alien species have complex spatiotemporal patterns of spread beyond geographical and jurisdictional boundaries. This calls for a coordinated management approach that is spatially explicit, extends beyond individual plot levels, and incorporates land users’ perceptions and decisions. This study, therefore, aims at assessing spatiotemporal invasion trajectories of the invasive tree Prosopis juliflora in Baringo County, Kenya, and evaluating their possible relation to land users’ management decisions. Pre-classified land cover data over a seven-year time period (1988–2016) were reclassified based on the presence or absence of P. juliflora and integrated into ArcGIS to produce P. juliflora cover trajectories for analysis ...

Enhancing Grassland Biodiversity And Its Consequences For Grassland Management And Utilisation, Johannes Isselstein

International Grassland Congress Proceedings

Key points

1. Grasslands make an important contribution to the biodiversity of rural landscapes.

2. Biodiversity has the potential to support the production function of grassland. The conditions for this are largely unexplored.

3. The enhancement of biodiversity on agriculturally improved, species-poor grasslands is difficult to achieve due to seed limitation and high residual soil fertility.

4. Measures to overcome constraints are addition of propagules, depletion of soil nutrients, and the use of specific sward treatments.

5. Agri-environmental schemes will play an increasing role in achieving the biodiversity targets in the future, however, the efficiency of such schemes needs improvement.

Understanding Common Perceptions Of The Drylands, C. Bedelian, D. Pertaub, F. Ngarachu, C. Hesse, S. Krätli, J. Obando, C. Shisanya, J. Maraigua

International Grassland Congress Proceedings

Drylands occupy over 40% of the earth’s surface and are home to more than 2 billion people. Drylands are key to the food and nutritional security of the planet and vital to the economies and livelihoods of dryland inhabitants. Yet, drylands are commonly perceived as unproductive, economically inefficient and marginal lands where small-scale farmers and pastoralists practice environmentally degrading activities. Driven by inadequate understanding and misconceptions of the drylands, policy-makers devise inappropriate policies and interventions. The BRECcIA project developed an online Drylands Perceptions Survey to understand the perceptions of researchers, practitioners and policy makers working in the drylands of ...

Phenotypic Evaluation Of Energycane Varieties For Bioenergy, Wyatt Eason, D. M. Hollowell, Anna Hale, Jesse Ira Morrison, Brian Baldwin Mar 2022

Phenotypic Evaluation Of Energycane Varieties For Bioenergy, Wyatt Eason, D. M. Hollowell, Anna Hale, Jesse Ira Morrison, Brian Baldwin

International Grassland Congress Proceedings

The need for renewable and carbon-neutral energy is growing as fossil fuel supplies decrease and concerns of climate change increase. C4 grasses are among the most efficient carbon accumulators. Sugarcane (Saccharum officinarum) is a renewable bioenergy crop with low inputs and high yields, but it is limited to tropical and sub-tropical climates. A close relative, Saccharum spontaneum, readily hybridizes with S. officinarum. S. spontaneum lends cold tolerance and higher yields to the hybrid progeny, called energycane. The Sugarcane Breeding Unit (USDA, Houma, Louisiana, USA) selected twenty-six genotypes for testing at Mississippi State University to determine production and cold tolerance ...

Grassland Productivity And Water Quality: A 21St Century Issue, David M. Nash, P. M. Haygarth

International Grassland Congress Proceedings

Key points

1. Irrigation and other changes to the hydrological cycle can increase soil and water salinity.

2. Primary salinisation is a natural process that affects much of Europe, Asia, Africa, the Americas and Australia. Secondary salinisation is caused by human activities such as irrigation and land clearing that mobilise salt stored in the soil.

3. The critical water contaminants exported from grasslands are nitrogen, phosphorus, potential pathogens and sediment.

4. The mechanisms responsible for diffuse pollution from grasslands and mitigation strategies are most effectively investigated using a ‘source-mobilisation-transport’ framework.

5. There is a lack of coherent interaction across discipline ...


Soil Quality Assessment And Management, M. G. Kibblewhite Mar 2022

Soil Quality Assessment And Management, M. G. Kibblewhite

International Grassland Congress Proceedings

Key points

1. Soil quality is related to the capacity of soil to deliver ecosystem services on a sustainable basis.

2. Effective management of soil within grasslands can deliver many benefits to mankind but poor management may cause loss of soil quality from erosion, loss of organic matter, physical deterioration etc.

3. Services are delivered from soil by biological processes. Soil quality depends on the form and condition of the soil habitat. Fixed factors (e.g. texture) are useful for assigning soil to types. Variable factors (e.g. organic carbon) can then be used to assess quality within soil types ...


Water Resources, Agriculture And Pasture: Implications Of Growing Demand And Increasing Scarcity, M. W. Rosegrant, R. A. Valmonte-Santos, S. A. Cline, C. Ringler, W. Li Mar 2022

Water Resources, Agriculture And Pasture: Implications Of Growing Demand And Increasing Scarcity, M. W. Rosegrant, R. A. Valmonte-Santos, S. A. Cline, C. Ringler, W. Li

International Grassland Congress Proceedings

Key points

1. Water availability for irrigation is threatened in many regions by rapidly increasing demand for nonagricultural water uses in industry, households, and the environment. The scarcity of irrigation water will not only impact crop production, but also meat production, as much of the pasture used to feed livestock is irrigated.

2. Grassland is caught between two countervailing forces: a requirement for increasing meat demand that boosts the need for additional pasture to support livestock production, and rapidly increasing water scarcity that makes pasture irrigation uneconomical.

3. The most effective means of dealing with water scarcity is likely to ...
