Early growth, biomass allocation, and nutrient stoichiometry of Pinus pseudostrobus seedlings grown in commercial and locally available substrate mixtures

Seedling quality is a key determinant of reforestation success, yet the use of peat moss ( Sphagnum sp.) as the dominant substrate component imposes economic and logistical barriers for community nurseries in developing countries. We evaluated the early growth, biomass allocation...

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...

Seasonal forcing and substrate legacy shape the biogeochemical organization of rooftop vs. ground-level urban gardens

Urban agriculture is expanding rapidly in densely populated cities, yet the ecological functioning of rooftop soils relative to ground-level gardens remains poorly understood. We evaluated soil carbon and nitrogen cycling, microbial activity, and broad microbial community structu...

One Core to Root them All: A Core Bacterial Community in Closely Related but Geographically Distant Mammillaria Species from Contrasting Environments

Abstract Understanding the core microbiome has potential applications on biomonitoring and conservation. We explore whether closely related xerophytes from the M ammillaria h aageana s pecies c omplex (MHSC), a recently diverged group (ca. 2 mya) that occupy geographically distan...
