Forest Defoliation By And Invasive Outbreak Insect: Catastrophic Consequences For A Charismatic Mega Moth, Richard L. Lindroth, Mark R. Zierden, Clay J. Morrow, Patricia C. Fernandez

Aspen Bibliography

Earth is now experiencing declines in insect abundance and diversity unparalleled in human history. The drivers underlying those declines are many, complex, and incompletely known. Here, using a natural experiment, we report the first test of the hypothesis that forest defoliation by an invasive outbreak insect compromises the fitness of a native insect via damage-induced increases in toxicity of the forest canopy. We demonstrate that defoliation by the invasive spongy moth (Lymantria dispar) elicits an average 8.4-fold increase in foliar defense expression among aspen (Populus tremuloides) genotypes. In turn, elevated defense dramatically reduces survivorship, feeding, and …

Association Mapping Of Important Agronomic Traits In Mucuna Pruriens (L.) Dc., Patrush Lepcha, Mahesh Shekhar, Leelambika Murugesan, Mahammad Jaheer, Ratan Chopra, Vikas Belamkar, Narayana Sathyanarayana

Department of Agronomy and Horticulture: Faculty Publications

Background The tropical legume Mucuna pruriens (L.) DC. can meet three agricultural needs: low-cost protein, highvalue medicines, and green manure or cover crops. But like other underutilized crops, it needs more modern breeding resources. Identifying marker-trait associations (MTAs) can facilitate marker-assisted breeding and crop improvement. Recent studies have demonstrated the feasibility of identifying MTAs using a small number of accessions (< 100). We have characterized a panel of 70 M. pruriens accessions across two consecutive years and performed association analysis for 16 phenotypic traits related to seed (seed length, seed width, seed thickness, seed yield per plant, hundred seed weight); pod (pod length, pod width, number of pods …

Actuarial Implications Of Prevented Planting Coverage, Dylan Turner, Francis Tsiboe, Hunter D. Biram, Lawson Connor

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Within the Federal Crop Insurance Program (FCIP), prevented planting (PP) coverage provides payments for pre-planting costs associated with crops that ultimately cannot be planted due to adverse weather. PP indemnities, which are not considered production losses within the FCIP rating methodology, influence premium rates differently than typical losses. This study utilizes a panel data set consisting of approximately 77,697 county level observations from RMA's summary of business to identify the relationship between the prevalence of prevent plant use and a number of actuarial related outcomes. Overall, we find that increases in the share of total indemnities attributable to PP claims …

Software Solutions In Agri-Food Supply Chains: A Current View For Sustainability Reporting, Ryan Loy, Logan L. Britton, Trey Malone

Department of Agricultural Economics Faculty Publications

Environmental impact reporting has become a lynchpin for global agri-food supply chain decision-making. This importance has become heightened as governing bodies such as the European Union pass traceability legislation in an effort to reduce Scope 3 emissions. Despite this heightened importance, few studies have explored the role of supply chain management software in achieving sustainability goals within the agribusiness sector. This article provides a current perspective on ongoing supply chain and logistics software issues that might restrict the effectiveness of sustainability reporting. We argue that agribusinesses may struggle to achieve sustainability targets effectively without proficiency in supply chain software. This …

A Comparison Of Diploid And Triploid Eastern Oysters For Aquaculture Production Under Extreme Temperatures And Salinities, Joshua H. Kim

LSU Master's Theses

Off-bottom aquaculture of Eastern oysters (Crassostrea virginica) is a nascent industry that is increasingly supported by the use of triploid oysters, which grow faster than diploids. Despite their growth advantage, elevated triploid mortality compared to diploids under high temperature, low salinity, or a combination of these conditions challenge consistent triploid production. Identifying the environmental thresholds at which differential triploid mortality occurs and predicting its economic impact are important to informing decision-making in oyster aquaculture. The goal of this thesis was to compare the biological and economic performance of diploid and triploid oysters under high temperature and low salinity conditions. …

Turkish Journal of Agriculture and Forestry

Global crop yield and growth are severely impacted by hazardous heavy metal contamination of the soil and water. This study examined the effects on a range of physiological, biochemical, and morphological parameters of two canola (Brassica napus L.) cultivars, Punjab (V1) and Super (V2), when they were subjected to three different levels of cadmium (Cd) stress (0, 1.5, and 2.25 mM) and foliar application of biostimulant, i.e., Moringa leaf extract (MLE). Plants in V1 (Punjab) collect more Cd in both their aerial and subterranean sections than in V2 (Super).The morphological and physiological indicators showed a substantial (p < 0.05) deterioration as a result of the Cd buildup. Ascorbic acid and malondialdehyde (MDA) and hydrogen peroxide (H2O2) were considerably (p < 0.05) elevated under Cd stress. V1 has considerably higher H2O2 values than Super (V2), which suggests that oxidative stress levels there are higher. Additionally, the activity of some antioxidant enzymes, such as catalase and peroxidase (65 and 40%, respectively), were reduced by a higher concentration of Cd (2.25 mM). V2 demonstrated stronger antioxidant defence mechanisms than V1, as seen by a 115% rise in POD activity, a 70% increase in shoot fresh weight, and a 49% increase in amino acids following MLE spray. Despite this, the V2 was still able to withstand Cd. Under Cd stress, foliar treatment of MLE increased both kinds' yield, growth, biochemical, and physiological characteristics. The findings indicated that applying MLE foliar spray can improve crop productivity and lessen the impacts of metals on B. napus L.
