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.

Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Understanding the Molecular Processes of Obesity and the Anti‐Obesity Properties of Bioactive Substances Found in Tea

Phytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
ABSTRACT Obesity, a severe worldwide health concern, is characterized as an excessive deposit of fat in the human body. It has various ramifications that endanger human health and increase the financial expense. Obesity raises the risk of several illnesses, notably cardiovascular disease, NALFD, and diabetes, and has been associated with shorter ...

Comparative Metagenomics of Freshwater Cyanobacteria Bloom and Non-Bloom Sites in Ontario and the Investigation into the Utilization of Conserved Signature Proteins for Identification of Cyanobacteria [PDF]

, 2017
Cyanobacterial algal blooms have been increasing in frequency and severity over the past few years in Ontario. Depending on the presence of toxigenic Cyanobacteria, these blooms have the potential to release toxins into the water, posing a public and ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Gut microbiota‐targeted interventions for depression in adolescents and young adults: Mechanisms, evidence strength and clinical strategies—A narrative review

General Psychiatry, Volume 39, Issue 4, August 2026.
ABSTRACT Depression in adolescents and young adults is common, associated with substantial functional impairment and characterised by limited treatment efficacy. The microbiota–gut–brain (MGB) axis has emerged as a potential therapeutic target for depression.

The combined effects of UV-B radiation and herbicides on photosynthesis, antioxidant enzymes and DNA damage in two bloom-forming cyanobacteria [PDF]

, 2012
In this study, we investigated the combined effects of UV-B irradiation and herbicides (glyphosate, GPS; 2-Methyl-4-chlorophenoxyacetic acid, MCPA-Na; 3-(3,4-dichlorophenyl)-1,1-dimethylurea, DCMU) and the antioxidant (ascorbic acid, ASC) on ...
