Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, Volume 2026, Issue 3, March 2026.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Evaluating the Limitations of One‐Dimensional High‐Temperature Gas Chromatography ‐ FID for Wax Solution Analysis: A Systematic Study

Journal of Separation Science, Volume 49, Issue 3, March 2026.
ABSTRACT Wax deposition in petroleum systems is intrinsically connected with paraffin wax composition, yet their quantitative characterization by one‐dimensional high‐temperature gas chromatography with flame ionization detection (HTGC–FID), as prescribed by ASTM D5442, remains challenging.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

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

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.
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

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 ...

Carbon/TiO2 Materials From Textile Waste: A Sustainable Approach for Dye Removal

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT This study synthesized carbon/TiO2 composites from textile waste through titanium isopropoxide impregnation and calcination to address dye contamination in wastewater. The composites exhibited enhanced specific surface area and pore volume with higher TiO2 content.
