Fish Assemblages in an Urbanized Neotropical Basin: Influence of Environmental Factors Across Dry and Rainy Periods

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT This study investigated the effects of season and environmental disturbances on fish communities in neotropical rivers of the Sorocaba basin, a Sub‐Basin of the Paraná River in Southeast Brazil, based on sampling 1196 individuals from 49 species, including two non‐native and one threatened with extinction.

Decomponology: A board game for understanding soil carbon dynamics

open access: yesNatural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Soils sustain life and regulate global carbon cycling, yet the processes governing soil organic matter dynamics are inherently complex, involving multiple pathways and positive and negative feedbacks. Traditional concepts such as humus often portrayed soil carbon as a static pool whose persistence was attributed largely to the inherent ...

The Communication of a Creeping Crisis: Why Messages Are Recognized but Rarely Taken Into Account in Practices—The Case of Drought

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 17, Issue 4, December 2026.
ABSTRACT Public communication campaigns on environmental issues rely on economic and ecological arguments, assuming that the recognition of messages is sufficient to produce adjustments in practices. Drought constitutes a specific case of this problem, as a creeping crisis: a slow‐onset hazard whose effects remain weakly visible in everyday life.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, Volume 41, Issue 12, Page 1688-1700, December 2026.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Social bees can enhance the persistence of plant–bee interactions during seasonal changes in seasonally dry tropical forests

open access: yesEcological Entomology, Volume 51, Issue 6, Page 1230-1245, December 2026.
Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

open access: yesNew Phytologist, Volume 252, Issue 5, Page 1943-1961, December 2026.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Ten rules for robust taxonomy in ecological datasets

open access: yesNew Phytologist, Volume 252, Issue 5, Page 1741-1749, December 2026.
A workflow for better use and integration of taxonomic‐related information into ecological datasets. Summary Accurate taxonomy, including species identification and naming, underpins ecological inference, yet taxonomic information in ecological datasets is often inconsistently recorded or weakly standardized.

Mixed‐vertebrate pollination traits and pollinators of Haageocereus acranthus (Cactaceae) in a lomas desert ecosystem of coastal Peru

open access: yesPlant Biology, Volume 28, Issue 7, Page 2337-2352, December 2026.
In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

A dual pollination strategy combining perfume attraction and food deception in Galeandra blanchetii E.S. Rand (Orchidaceae)

open access: yesPlant Biology, Volume 28, Issue 7, Page 2313-2326, December 2026.
Galeandra blanchetii exhibits a dual‐attraction strategy: male euglossine bees are lured by floral scents as a resource, while both sexes are deceived by non‐existent nectar. Pollination only occurs when bees enter the spur to search for nectar, highlighting an evolutionary transition towards the perfume flower syndrome in Catasetinae.

Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

open access: yesPlant Biology, Volume 28, Issue 7, Page 2327-2336, December 2026.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...
