Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Unveiling Float Glass Staining Induced by an Acid‐Cleaning Product

International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
ABSTRACT Staining of glass facades is a recurring and significant problem worldwide. This study investigates the causes of staining observed on six laminated float glass samples from four manufacturers (α, β, γ, and δ). Samples from β, γ, and δ were new, whereas those from α (α1, α2, and α3) were taken from a building after service exposure.

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4597-4612, September 2026.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Environmental and Chemical Factors Determining the Structure of Leaf Litter Sporulating Conidial Fungi Communities in Two Preserved Areas of Brazilian Atlantic Forest

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
The Brazilian Northeast shelters fragments of the Atlantic Forest that, although historically under‐sampled, are home to a high diversity of organisms. In this context, conidial fungi are crucial for ecological balance, standing out for their role in the decomposition of organic matter and nutrient cycling.
