Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

open access: yesPeople and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

EFEITO DE ÉPOCAS DE DEFICIÊNCIA HÍDRICA NA EFICIÊNCIA DO USO DO NITROGÊNIO DA CULTURA DO FEIJÃO cv. IMBABELLO

open access: yesScientia Agricola, 1996
Visando identificar estádios da cultura de feijão que apresentam a menor sensibilidade ao estresse de água no solo, nos quais a irrigação pode ser omitida sem um significativo decréscimo na eficiência de uso de nitrogênio e na produtividade final, foi ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Small understory trees increase growth following sustained drought in the Amazon

open access: yesNew Phytologist, EarlyView.
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Diversity of Terrestrial Malacofauna, Favorable Habitats, and Relationships With Mollusk Size in Urban Environments of Sergipe, Northeastern Brazil

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
The invasive exotic snail Achatina fulica dominates the terrestrial mollusk community in the city of Aracaju, occurring in all sampled urban habitats and being the most abundant species among the individuals collected. In addition, it exhibited a larger shell size and greater total weight, particularly in back gardens. ABSTRACT Terrestrial mollusks can
