The influence of Mesoamerican obsidian mining on Technosols formation: A case study in las Navajas, Hidalgo, Mexico

Pre-Hispanic obsidian mining in Mesoamerica was one of the earliest and most widespread anthropogenic landscape modifications in the Mexican Central Highlands, yet its long-term impact on pedogenesis and Technosol formation remains poorly understood. The green‑gold obsidian depos...

A New Genus of Oak Gall Wasp, Striatoandricus Pujade-Villar (Hymenoptera: Cynipidae: Cynipini) from America with Descriptions of Two New Mexican Species

section. Descriptions of the genus and diagnostic characters, including DNA sequence data, are presented. This new genus is supported by both morphological and molecular data.

Spatial co-occurrence of exotic species in an urban reserve in Mexico City

Exotic species can interact positively or negatively with other exotic species. The patches of original vegetation immersed within some urban centers may be vulnerable to invasion by exotic species, which may compromise the value of these urban ecological reserves for the conserv...

Agave Species Influence the Taxonomic and Predicted Functional Structure of Traditional Pulque Inoculum Microbiomes

Pulque is a traditional Mexican beverage produced by the spontaneous fermentation of “aguamiel”, the sap of several Agave species. Fermentation is driven by adding a previously fermented inoculum, locally known as “semilla”, whose microbial community contributes to the sensory an...

Soil Yeasts from Sugarcane Agroecosystems: Nutrient Cycling and Biocontrol Potential in Agricultural Systems

Soil yeasts represent a significant component of the agricultural microbiota and possess high ecological and biotechnological potential in production systems such as those for sugarcane. This review analyses the importance of these microorganisms in fundamental processes related...

Analysis of the Prices and Opportunity Costs of Carbon Capture Projects in Mangroves Compared to Those in Other Productive Systems

Mangroves are highly productive ecosystems due to their great capacity to store carbon, but they are also vulnerable to human activities and adverse environmental conditions. Their conservation is often constrained by the opportunity costs of shifting from traditional economic ac...

Untargeted Metabolomics of Xylem Sap Exudates in Two Common Bean Genotypes with Contrasting Growth Rates Under Water Deficit During Pod Filling

Background/Objectives: Water deficit during the pod filling stage severely limits the productivity of common beans (Phaseolus vulgaris). Although the effects of water scarcity have been extensively studied in leaves and roots, the contribution of xylem sap to systemic metabolic a...

The Role of Prior-Induced Regularization in Accuracy and Stability of Genomic Prediction Across Unimodal and Multimodal Models

In this study, we assessed the impact of prior-induced regularization using six real datasets from wheat, rice, and potato, spanning 107–758 genotypes, 2–12 environments, 1–18 traits, and 2744–108,024 molecular markers. Two modeling scenarios were evaluated: (i) unimodal genomic...

Perception and Willingness to Pay for Mitigation of Tree Risk in a Peri-Urban Park in Central Mexico

People’s perception of tree risk in peri-urban environments influences decision-making on mitigation measures. This research aimed to determine the factors affecting the perception of visitors to Molino de Flores Netzahualcóyotl National Park (PNMFN) regarding the risk of tree fa...
