Grazing intensity regulates cattle movement and forage-use-efficient behavioral patterns through vegetation and abiotic pathways in a temperate meadow steppe

Livestock movement and time allocation are key behavioral processes linking grazing pressure to grassland use efficiency, yet how these behaviors respond to quantified grazing intensity and associated vegetation and abiotic conditions remains insufficiently understood. In this st...

Metabolic Engineering of Yarrowia lipolytica for Efficient De Novo Synthesis of Astaxanthin Glucosides via Enhanced UDP-Glucose Supply

Abstract Astaxanthin is a high-value carotenoid used in nutrition, cosmetics, pharmaceuticals, and biotechnology, but its poor water dispersibility and oxidative stability limit its formulation. Here, we engineered yeast Yarrowia lipolytica for the efficient production of glycosy...

Can small reductions in Rubisco content improve nitrogen use in wheat without negatively impacting biomass or grain yield?

In this study, the level of Rubisco protein was reduced in wheat using RNAi, to test the hypothesis that photosynthesis, growth, and grain yield could be maintained whilst improving nitrogen use efficiency. The RNAi Rubisco wheat plants, with a Rubisco activity of less than 70% o...

Loss of salt iodization harmed child survival and academic achievement in Ethiopia

Abstract The introduction of salt iodization is associated with improved health and socioeconomic outcomes, but is not yet universally adopted and not always sustained. Using a quasi-experimental event study with difference-in-differences over space and time, we quantify the impa...

The Potential Inhibitory Effect of Copper and Nickel on Gaseous Soil N Emissions

Nickel (Ni) and copper (Cu) are essential soil micronutrients that are beneficial for plant growth and development when applied at the right levels to deficient soils. However, they can also be of concern if excessive application leads to accumulation in soil, causing soil fertil...

Single and MultipleInfestation by Coccoid Pests inCoffee Shape Plant Chemical Defenses and Interactions Across TrophicLevels

Abstract Crop plants are attacked by multiple pests, inducing metabolic changes that shape interactions across trophic levels and influence the effectiveness of biological control. We examined how infestation by the coccoids Coccus viridis (scales) and Planococcus citri (mealybug...
