Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...

fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1585-1594, May 2026.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

Pest Management Science, Volume 82, Issue 4, Page 2910-2924, April 2026.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

Plant canopies sustain soil C‐N‐P enzyme activities under climatic disequilibrium

Journal of Ecology, Volume 114, Issue 4, April 2026.
Our findings reveal that plant–soil interactions are sensitive to mismatches between plant communities and climate. By enhancing enzymatic functioning under conditions of climatic disequilibrium, canopy plants contribute to maintaining nutrient cycling processes and potentially ecosystem resilience.

Accumulation of Methylmercury in the High-Altitude Lake Uru Uru (3686 m a.s.l, Bolivia) Controlled by Sediment Efflux and Photodegradation

Applied Sciences, 2020
In shallow aquatic environments, sediment is a significant source of monomethylmercury (MMHg) for surface water (SW). High-altitude aquatic ecosystems are characterized by extreme hydro-climatic constraints (e.g., low oxygen and high UV radiation).
