Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

River Research and Applications, Volume 42, Issue 5, Page 997-1010, June 2026.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Influence of the Dynamic Geological History of the Japanese Archipelago on the Molecular Phylogeography of the Riffle Beetle Zaitzeviaria ovata (Coleoptera: Elmidae)

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The geographic genetic structure and distribution within species are shaped by factors such as dynamic tectonic activity and topographic changes associated with climate change. We used the largely flightless, freshwater‐dependent beetle Zaitzeviaria ovata (Elmidae) as a model to investigate how ancient topography and dynamic geological history

Impact of the Highly Invasive Signal Crayfish (Pacifastacus leniusculus) on Freshwater Macroinvertebrate Communities

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Invasive non‐native species threaten freshwater ecosystems, disrupting the functioning and structure of the food chain and potentially leading to biodiversity loss. As omnivores, crayfish can modify their environment, directly affecting organisms such as macroinvertebrates.

Winter wipeout? Post‐disturbance recovery of brown trout indicates strong population resilience to harsh winter conditions

Oikos, Volume 2026, Issue 1, January 2026.
Demographic resilience refers to the capacity of a population to resist and recover from disturbances in terms of both population size and structure. Resilience to severe disturbance events, such as heatwaves, floods, and cold snaps, is likely to vary with the life‐history characteristics of the population, such as migratory strategy, and demographic ...

Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress

Global Change Biology, Volume 32, Issue 1, January 2026.
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Experimental droughts in mesocosms reveal a gradient of tolerance in Alpine stream macroinvertebrates

Limnology and Oceanography, Volume 70, Issue S2, Page S352-S363, December 2025.
Abstract Prolonged droughts, driven by climate change and human pressures on water resources, are increasing in frequency and intensity, particularly impacting Alpine rivers. Benthic macroinvertebrates are one of the most important structural and functional components of Alpine lotic ecosystems.
