Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Diet composition of the Red‐billed curassow (Crax blumenbachii) and its role as seed disperser in the Atlantic Forest: conservation insights

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Forest fragmentation and defaunation are major drivers of biodiversity loss in the Atlantic Forest of Brazil, where 70–90% of tree species depend on animal‐mediated seed dispersal. Reintroduction of large frugivores, such as cracids, is being used to restore species populations and lost ecological functions.

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, Volume 16, Issue 3, Page 364-395, June 2026.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

Seroprevalence and Risk Factors for Hepatitis E Virus in a Metropolis of Northeastern Brazil: A Population‐Based Survey

Zoonoses and Public Health, Volume 73, Issue 4, Page 326-335, June 2026.
ABSTRACT Introduction Hepatitis E virus (HEV) is a leading cause of acute hepatitis worldwide. While traditionally linked to poor sanitation in endemic areas, evidence shows increasing circulation in developed settings. In Brazil, however, population‐based data remain limited.
