Spatial Prediction of Tractor Noise and Detection of Atypical Sound Pressure Levels Using Machine Learning

Prolonged exposure to high sound pressure levels (SPLs) in agricultural tractors, especially when the power take-off (PTO) is engaged, poses serious health risks to operators. While machine learning has been applied in agriculture, little progress has been made in predicting SPLs...

Effect of sonication on European and Peruvian lupin flours: impact on the technological quality of gluten‐free breads and as a partial substitute for wheat

BACKGROUND: A widely cultivated pulse, lupin, has garnered interest for its beneficial nutritional properties, especially for baking applications. The harmful alkaloid content and poor functional properties of lupin limit its wider use. Sonication is an ecofriendly technology use...

Tree Diversity, Floristic Composition, and Forest Structure in Three Permanent Montane Forest Plots in Northern Peru

Tropical montane forests provide essential ecosystem services and are of considerable ecological importance. However, knowledge gaps remain regarding how tree diversity, floristic composition, and forest structure vary among permanent plots across the sampled elevational range (2...

Intestinal Microbiota Response to Dietary Hermetia illucens Meal in Cultured Finfish: A Systematic Review

This review synthesizes the available evidence on the effects of Hermetia illucens meal inclusion on the intestinal microbiota of fish. A literature search was conducted in Scopus, Web of Science, PubMed, and Embase from inception to 23 April 2025, including in vivo experimental...

Large-scale climate drivers of extreme compound events in the Amazon from interannual to long-term timescales (1982–2024)

Abstract Over recent decades Amazonia has experienced a marked intensification of floods and droughts. The record-breaking 2023–2024 drought, characterized by exceptional heat and dryness, motivates a closer analysis of compound extremes and their large-scale drivers. This study...

Valorization of Postharvest Mandarin Residues in the Production of Pectins and Distillates with Antioxidant Capacity

Non-marketable postharvest residue from Satsuma Owari mandarins (Citrus unshiu)—discarded due to having a puffy peel (MC) or being damaged (MD)—was evaluated against a commercial mature reference (MM) using an integrated cascade biorefinery. Along the liquid pathway, must ferment...

Characterization of the ecological impacts of prescribed fire in South America: a review

Prescribed fire has been shown to offer substantial benefits to both human populations and ecosystems, but it can also cause environmental harm, such as reduced air quality and negative impacts on sensitive species. To support the appropriate use of prescribed fire, stakeholders...

Effect of planting density on the agronomic performance and forage potential of Vicia sativa L. in the high Andes of Peru

In the high Andean regions of Ancash, Peru, limited high-protein forage during dry seasons challenges livestock feeding. A locally adapted ecotype of common vetch ( Vicia sativa L.) grows spontaneously and shows resilience to harsh conditions. This study evaluates its agro-morpho...

Phytoextraction of Cadmium Using Solanum nigrum and Bidens pilosa: Comparative Evaluation and Effect of Planting Distance in Theobroma cacao L. Producing Areas in Northeastern Peru

Cacao (Theobroma cacao L.) is a crop of great economic importance in Peru; however, the presence of cadmium (Cd) in cacao-growing soils limits its production and international trade. The objective of this study was to evaluate the effect of Solanum nigrum (black nightshade) and B...

Field-Scale Evapotranspiration of Flood-Irrigated Rice with Automated METRIC on Google Earth Engine in an Arid Region of Northern Peru

Irrigation water management in arid systems requires spatially distributed estimates of crop evapotranspiration (ET) that fixed crop coefficients cannot provide. The actual ET of flood-irrigated rice (Oryza sativa L.) on the arid northern coast of Peru was mapped with the METRIC...
