Grassland afforestation more than forestry intensification shapes soil multifunctionality via microbial compositional change under abiotic constraints

Martín N. Ribero, María Romina Schiaffino, Julieta Filloy

Soil ecosystem multifunctionality (EMF) is driven by the interplay of abiotic and biological factors, yet how these interactions respond to anthropogenic pressures remains poorly understood. Here, we evaluated how grassland afforestation and its intensification shape soil edaphic conditions, microbial diversity, and EMF …

WHONDRS Surface Water Geochemistry and Organic Matter Characterization Data from Streams Distributed across Latin America

Amy Goldman, Gabriel S. Alfaro-Vergara, Marcela Bastidas Navarro, Adam Baumann et autres

This dataset supports a broader study examining global transferability of stream biogeochemistry and was generated in collaboration with the MicroSudAqua (µSudAqua) network (https://microsudaqua.netlify.app/en/). The dataset provides surface water geochemistry (dissolved organic carbon, total dissolved nitrogen, cations) and organic matter characterization (FTICR-MS) from …

Cumulative ecological risk of pesticide mixtures in an agricultural river of the pampa region: Identifying critical contaminants for practice and policy reform

Julie C. Brodeur, Ana Clara Caprile, María Romina Schiaffino, Ariana Rossen et autres

Agricultural breadbaskets are vital for global food security, yet reliance on pesticides poses a threat to regional aquatic ecosystems. This study evaluates the cumulative ecological risk of pesticide mixtures in a river system of Argentina's Pampa region, a global agricultural heartland. Over …

How Do Environmental and Spatial Factors Influence Beta Diversity and Composition of Abundant and Rare Bacterioplankton Communities in Lakes From the Patagonian Plateaus?

Sol Porcel, Carmen Alejandra Sabio y García, María Romina Schiaffino, Griselda Chaparro et autres

ABSTRACT Lakes in the same geographic region often exhibit outstanding differences in environmental features, as is the case in the high‐altitude lakes from the basaltic plateaus of Patagonia (Argentina). We analysed bacterial community composition (BCC) at local and regional scales in 37 …

A georeferenced rRNA amplicon database of aquatic microbiomes from South America

Sebastián Metz, Paula Huber, Erick Mateus‐Barros, Pedro C. Junger et autres

Here we present the samples and data used in Metz & Huber et al. (2022) to construct µSudAqua[db]. µSudAqua[db] contains over 866 georeferenced samples with contextual environmental information manually revised. For its integration and validation, we constructed a curated database (µSudAqua[db.sp]) using …

Grassland Afforestation Drives Biotic Homogenisation of Soil Microbial Communities at a Regional Scale

Martín N. Ribero, María Romina Schiaffino, Julieta Filloy

Grassland afforestation poses a threat to biodiversity beyond land-use conversion. Diversity patterns are shaped by temporal dynamics, particularly, time since afforestation can decline beta diversity and lead to biotic homogenisation. Our study examines the effect of grassland afforestation on soil prokaryotic and …

A Latin American network of microbial observatories for monitoring aquatic ecosystems

Paulina Fermani, Nicolás Martyniuk, Martín Saraceno, Marina Gerea et autres

Freshwater environments and coastal marine areas provide key ecosystem services to society and serve as habitats for biodiversity. However, they face major challenges from human activities and climate factors, leading to global degradation. The effect of these agents depends on geographic location …
