Ensemble agroecosystem modeling enhances predictions of crop yields and soil carbon across the United States

Abstract. Accurately estimating crop yields and soil organic carbon (SOC) dynamics is essential for agricultural planning, carbon accounting, and sustainable land management. However, process-based agroecosystem models often produce divergent estimates due to variations in model...

Multilocus-Derived Genetic Variability and Pathogenicity of Colletotrichum Species from the Mid-Atlantic United States Associated with Anthracnose in Pepper

Colletotrichum species are important fungal pathogens that cause fruit rots leading to pre and postharvest losses of a broad range of Solanaceae crops, including bell and non-bell pepper and fresh-market and processing tomato. We performed a phylogenetic and pathogenic characteri...

Differential Non-Fiber Agronomic Properties and Biochemically Related Fourier Transform Infrared Spectral Features of Cotton Genotypes with Contrasting Fiber Lengths

Abstract While Fourier transform infrared (FT-IR) spectroscopy is widely used in agricultural research, linking the FT-IR biochemical features to agronomic properties is quite limited. In this work, three cotton mutants with shorter fiber lengths (Li1, Li2, and liy) and two wild...

Direct avirulence effector-receptor interaction confers wheat immunity against insects

Wheat immunity against the global pest Hessian fly operates on a gene-for-gene basis, yet molecular mechanisms underlying resistance-avirulence interactions have remained elusive for over five decades due to the absence of any cloned insect-resistance gene. Here, we cloned the H1...

A cross-sectional study on identification and prevalence of hard ticks parasitizing large and small domestic animals

Ticks are blood-sucking ectoparasites transmitting pathogens that cause anemia, skin damage, weight loss, reduced meat and milk production, morbidity, and mortality in livestock. This study identified tick species and their prevalence on buffaloes, sheep, cows, and goats in Multa...

Gravel Transport from Impact Plates in the Goodwin Creek Experimental Watershed, Panola County, Mississippi

Abstract Gravel transport is difficult to measure in streams and rivers, but it is needed for assessing the impact of dam removal on river systems, for studies of streambed ecology, for steam restoration, and for engineering design of in-channel structures. The measurement of gra...

Supplementation with Yellow Mealworm (Tenebrio molitor) Larvae Grown on Deoxynivalenol-Contaminated Substrate Improves Growth and Gut Integrity in Broilers

Deoxynivalenol (DON), a Fusarium mycotoxin frequently detected in poultry feeds, impairs broiler health by damaging gut integrity, altering immune response, and compromising growth performance. Insect-derived proteins, such as those from yellow mealworm (Tenebrio molitor) larvae...

Parametric Study of Yields and Properties of Corn Stover-Derived Hydrothermal Liquefaction Products by Using Statistical Approaches

Hydrothermal liquefaction (HTL) of lignocellulosic biomass produces multiple product fractions, including solid residue (SR), heavy bio-oil (HBO), aqueous phase (AP), and light bio-oil (LBO). This study mainly applied principal component analysis (PCA) and regression modeling to...

Multi-scale evapotranspiration and evaporative stress as indicators of vegetation health and drought response – an application in central Missouri, USA

Satellite estimates of evapotranspiration (ET) based on thermal infrared retrievals of land-surface temperature enable monitoring of vegetation water use and health/stress at sub-field to global scales. The information content of these products varies with pixel size, reflecting...
