Tell me where you flow and I will tell you who you are: basin context shapes the insect fauna of small tributaries

open access: yesOikos, Volume 2026, Issue 8, August 2026.
The traditional view of river basins as linear corridors has led to numerous studies examining the effects of stream size on aquatic communities. However, similar‐sized streams may harbor distinct faunal assemblages depending on their spatial context within the basin. Headwater tributaries (HTs) that flow into small streams, in the periphery of basins,

Water and Gas Exchange Responses of Five Related Blueberry Species (Ericaceae spp.) to the Dry Season in the High‐Andean Forest of the Colombian Eastern Cordillera

open access: yesPlant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Vaccinium, Cavendishia, and Macleania are typical genera of blueberries from the Ericaceae belt, a narrow ecosystem that connects the high Andean forest and páramo, where fragmentation makes the species more vulnerable to climate change. To answer the question of whether five related blueberry species could physiologically behave similarly in ...

Phylogenetics of Clusia sect. Criuva (Clusiaceae) unveils a new species, reinstates an old name and clarifies sectional circumscription

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Clusia sect. Criuva has long been a taxonomic catch‐all, particularly in the final decades of the 20th century, when misapplications conflated eastern Brazilian taxa with species from the Guiana Shield. We combine herbarium‐based genome skimming, targeted fieldwork, and critical examination of historical literature and types to reassess ...

A revision of the genus Armeria (Plumbaginaceae) in peninsular Italy and Sicily through an integrative taxonomic approach

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Armeria in peninsular Italy has been affected by taxonomic ambiguity for more than a century due to high morphological variability. We present a comprehensive revision of peninsular Italian and Sicilian Armeria species, using an integrated taxonomic approach that combines molecular phylogeny, plant and seed morphometrics, and ...

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Peculiar Magnetosphere‐Atmosphere Coupling and Its Impacts Over the South American Magnetic Anomaly Region

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The auroral‐like sporadic E‐layer is typically observed at altitudes between 100 and 150 km within the South American Magnetic Anomaly region. However, the occurrence of an unusual layer event detected above this altitude range on 18 July 2017 has raised intriguing questions regarding the physical processes responsible for the substantial ...
