A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Integrated Renewable Energy for Urban and Remote Communities: Hybrid Solutions with Hydro Pumped Storage and Green Hydrogen Opportunities

Advanced Sustainable Systems, Volume 10, Issue 5, May 2026.
Urban and remote communities face inefficiencies from centralized power grids. This study assesses hybrid renewable energy systems with storage, integrating pumped hydro and hydrogen. Through modeling and optimization, demand–supply balance improves. The base case achieves low LCOE, strong returns, and energy export potential.

Enhancing Food Safety in the Cold Chain Through Internet of Things and Artificial Intelligence

Journal of Food Science, Volume 91, Issue 2, February 2026.
ABSTRACT Effective cold chain management is crucial for ensuring food safety, but traditional monitoring approaches remain reactive and fragmented. Industry 4.0 technologies, such as the Internet of Things (IoT) and artificial intelligence (AI), offer transformative potential for real‐time tracking, automation, and predictive analytics.

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil

Journal of Fish Biology, Volume 108, Issue 2, Page 648-668, February 2026.
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...
