Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...

From Local Biodiversity to Global Food Security: Antioxidant Evidence of Unconventional Edible Plants (2020–2025)

Journal of Food Process Engineering, Volume 49, Issue 2, February 2026.
This scoping review (2020–2025) compiles validated evidence on the antioxidant potential of unconventional edible plants (PANCs). Thirty species showed high phenolic content and strong radical‐scavenging activity, reinforcing their role as natural antioxidants and sustainable alternatives to synthetic additives within biodiversity‐based food systems ...

Gems From the Caves: Genomic Insights Into the Biosynthetic Potential of Antimicrobial‐Producing Bacteria Associated With Tropical Cave‐Dwelling Sponges

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Our study reveals that cave‐dwelling marine sponges host bacteria with antimicrobial activity against multidrug‐resistant strains. The bioactive Pseudomonadaceae strains exhibited biosynthetic clusters encoding both characterized and putative antimicrobial compounds and peptides. The findings highlight their potential for discovering novel biomolecules

Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...

Cost Analysis of Radioactive Versus Arthroscopic Synovectomy in Haemophilia: A Brazilian Modelling Approach

Haemophilia, Volume 32, Issue 1, Page 231-238, January/February 2026.
ABSTRACT Introduction Radioactive synovectomy (RSO) is an alternative to arthroscopic synovectomy (AR), for treating synovitis. RSO reduces the number of hemarthroses, being less invasive and less costly. Objective To analyse the costs of RSO compared to AR in the treatment of patients with haemophilia in Brazil, using real‐world data (RSO) and ...
