A Macroinvertebrate‐Based Flow Index Elucidates Responses to Environmental Water in a Highly Regulated River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Macroinvertebrate‐based flow indices have potential application to guiding environmental flow allocations and monitoring their effectiveness, but their sensitivity to such flows has seldom been tested. We examined the response of the Australian Macroinvertebrate Flow Index (AMFI), calculated from family‐level data, to three stages of ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Sperm models in European Plecoptera

open access: yesArthropod Structure & Development, 2023
Systematic issues regarding Plecoptera are still debated, and the molecular data seem to be unable to definitively clarify the relationships within the order. Spermatozoa are under constant evolutionary pressure, and comparative spermatology can be useful in carrying systematic and phylogenetic information.

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

open access: yesInsect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Climate Change and Temperature‐Based Stratification in Shallow Lakes and Ponds in Warm Climate Regions

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Thermal stratification in shallow lakes (< 5 m, > 5 ha) and ponds (< 5 m, < 5 ha) in warm climate regions is understudied. A comprehensive review was done to identify the effects of climate change on stratification patterns, their effects on the ecology of shallow waterbodies and implications for management of shallow waterbodies.

Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

open access: yesEcography, Volume 2026, Issue 10, October 2026.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by
