Epixylic microbial communities as key regulators of methane emissions from submerged wood in a tropical hydroelectric reservoir

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Tropical hydroelectric reservoirs are recognized hotspots for greenhouse gas emissions, yet the role of submerged forests in these emissions remains poorly understood. In this study, we investigated the contribution of standing dead trees and their associated epixylic biofilms to methane (CH4) and carbon dioxide (CO2) emissions in the ...

Solar and Wind Energy Variability in Tropical South America: Seasonal Ocean‐Atmospheric Modulators

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Climate variability affects renewable energy production and thus considering it in planning is essential for achieving sustainable development. We present how climate (ocean‐atmospheric) variability modes modulate wind and solar radiation variability, thereby influencing renewable power generation in tropical South America.

Degradation and Restoration of Anthrosols in the Amazonia Under Contrasting Agricultural Practices: Evidence From the Assessment of Soil Physical Quality and Carbon and Nitrogen Stocks

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT This study was conducted to assess the impact of different agricultural practices on the physical quality and the carbon and nitrogen stocks of anthropogenic soils used by smallholder farmers in Central Amazonia, Brazil. Undisturbed and disturbed soil samples were collected at three depths (0–0.10 m, 0.10–0.20 m, and 0.20–0.30 m), with five ...

Ensemble Docking of FDA‐Approved and Peruvian Phytochemicals Against Monkeypox Virus Telomere‐Binding Protein

ChemistrySelect, Volume 11, Issue 9, 5 March 2026.
ABSTRACT Monkeypox is a reemerging zoonotic disease that has been spreading worldwide. Different approaches are being conducted to find effective treatments for this disease. To accelerate therapeutic discovery, we propose telomere‐binding protein (TBP) as a potential drug target because of its important role during virus maturation.

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.
