Delving in the Deep—Dominance of Non‐Native Species in Benthic Fish Assemblages in the Fragmented Large River Ecosystem of the Austrian Danube

open access: yesFreshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT River fragmentation through channelization and the construction of dams has strongly altered river ecosystems, leading to declines in native fish species and the proliferation of non‐natives. Knowledge gaps still exist about the effects of fragmentation on the structure of ecological assemblages throughout all habitats in large, fragmented ...

Freshwater Haplosporidian Diversity Associated With Invasive Non‐Native Bivalves in the River Thames, Including Haplosporidium raabei Infecting Dreissena polymorpha

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Haplosporidians are protistan parasites of aquatic invertebrates. Described here is the first report of the zebra mussel (Dreissena polymorpha) parasite Haplosporidium raabei in the River Thames, London, UK. The prevalence of this protist in the upper tidal Thames, Richmond, was higher than previously reported in other studies from the UK and ...

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1360-1378, September 2026.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Russia's Strategic Paradox: Short‐Term Gains, Long‐Term Risks from the Iran War

open access: yesMiddle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract How is the Iran War influencing Russia's foreign policy? This article argues that the conflict strengthens Moscow's short‐term strategic position while reinforcing the structural limits of Russian power. The analysis traces these effects across Russia's wartime economy, its position in Ukraine and the Middle East, and its relations with China ...

The Shrinking Caspian Sea: Eco‐Hydrological Responses to Human and Climate Pressures

open access: yesEarth's Future
The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on ...

The Impact of Russia–Ukraine War in Maritime Data

open access: yesThe World Economy, Volume 49, Issue 9, Page 1907-1923, September 2026.
ABSTRACT This study analyses weekly port calls from 2019 to 2026 to evaluate the Russia–Ukraine war's impact on maritime trade. The data reveals clear structural shifts that Ukrainian traffic moved from high‐risk areas like Odesa to safer Danube River ports.

Positive Association Between Coastal Sea Surface Temperatures and Humid Heat Stress on Nearby Land

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Large populations along Earth's coastlines are exposed to climate hazards including extreme humid heat. Considering observed coastal ocean warming and increased coastal marine heatwave (MHW) activity, we seek to uncover if, how, and where coastal ocean temperatures are linked with heat and humidity on land nearby.
