Integrative taxonomy reveals two new species of whiptail catfishes Loricaria (Siluriformes: Loricariidae) from northeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract Two new species of whiptail catfish, Loricaria (Siluriformes: Loricariidae), were discovered in the Munim and Itapecuru river basins, Maranhão State, northeastern Brazil, through an integrative taxonomic approach combining morphology and mitochondrial DNA.

Chlorophyll Estimation from Multivariate Regression Analysis and Deep Learning Using Remote Sensing Data

Engineering Proceedings, 2022
The Orinoco river is in Venezuela and flows into the Caribbean sea. The chlorophyll concentration in the ocean delta changes due to the dust deposition from the Orinoco river which affects the primary productivity. The wet and dry deposition measurements

Living in the Mycelial World

Topics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...

Molecular diagnosis of the arowanas Osteoglossum ferreirai Kanazawa, 1966 and O. bicirrhossum (Cuvier, 1829) from the Orinoco and Amazon River basins

Neotropical Ichthyology
The arowanas, fishes of Gondwanan origin, are represented in South America by the genus Osteoglossum. All species were initially reported as being exclusive to the Amazon region, with O. ferreirai restricted to the Negro River basin and O. bicirrhosum to

Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Hydrological seasonality shapes microbial biomass and diversity in an equatorial estuarine mangrove

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Mangroves are pantropical marine forests rooted in soft sediments and subject to pronounced seasonal variability. However, the effects of these hydrological fluctuations on root‐associated prokaryotic communities remain poorly understood, particularly in underexplored regions like the Guianas.

Thinking of Melastomataceae: Revisiting Humboldt and Bonpland's Monographie des Melastomacées (1806–1823) from a historical perspective

TAXON, Volume 75, Issue 3, June 2026.
Abstract During their voyage to the Americas (1799–1804), Alexander von Humboldt and Aimé Bonpland described and collected American flora, fauna, minerals and other objects. After returning to Europe, they published several works, including Monographie des Melastomacées, initiated by Bonpland to classify this complex botanical family.
