Drought and Human Pressures Contribute to Persistent Changes in Freshwater Invertebrate Communities

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Freshwater ecosystems are threatened by increasing climate extremes including drought, which interacts with human pressures to drive biodiversity loss across spatial scales. River communities are considered resilient to droughts, but this characterization is based on short‐term, small‐scale studies. Moreover, drought resilience is increasingly

Caddisfly Species Differ in Whether Intraspecific Variation in Wing Size Affects Dispersal in a Natural Landscape

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Species' metapopulation dynamics and connectivity can depend on whether dispersers comprise a random or phenotype‐dependent subset of the population. However, whether and which phenotypic traits characterise dispersing individuals is unknown for many invertebrates.

Widespread Underestimation of Drought Impacts on River Ecosystems Due to Weak Experimental Designs

Global Change Biology, Volume 32, Issue 7, July 2026.
Experimental design strongly influences the detectability and magnitude of estimated drought impacts. Simpler designs underestimate impacts relative to the more complex, but relatively rare (< 35% of the studies), Before‐After–Control‐Impact designs.

High interspecific variation in nutrient excretion within a guild of closely related caddisfly species

Ecosphere, 2018
Understanding the amount of variation in functional traits between closely related species within guilds is critical for understanding links between community composition and ecosystem processes.

Efficacy of Clearflow Treatment Technologies in the Treatment of Mining Effluent: Field‐Level Testing at a Coal Mine

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Mining waste water characteristically contains high concentrations of suspended solids, total metals, and nutrients. These can be treated with flocculants within settling ponds to speed up the clarification of water by settling out the suspended solids.

Contribution to the knowledge of the caddisfly fauna of Kosovo with first record of the genus Orthotrichia Eaton, 1873 (Trichoptera, Hydroptilidae) [PDF]

Journal of Insect Biodiversity and Systematics, 2023
Adult caddisflies were collected from the spring area located in the Blinajë Hunting Reserve in Kosovo between May and September 2022. In this study, we identified 21 species belonging to 9 families of caddisflies (Goeridae, Hydropsychidae, Hydroptilidae,

Allochthonous chemical cues drive predation by a top carnivore

Functional Ecology, Volume 40, Issue 6, Page 1698-1708, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Identifying the mechanisms by which mobile predators detect and select prey remains a central challenge in sensory biology and functional ecology. This study provides the first direct evidence that chemical cues associated with allochthonous organic matter (e.g.

Revision of the colourful genus Parasetodes McLachlan, 1880 (Trichoptera, Leptoceridae) [PDF]

Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis
The rare and beautifully colourful old-world Parasetodes is a so-called set-aside genus with unsettled taxonomy. For instance, a recent survey (Malicky 2006) has synonymised all the Palaearctic and Oriental species to the type species Parasetodes ...
