‘Rolling’ stoneflies (Insecta: Plecoptera) from mid-Cretaceous Burmese amber

PeerJ, 2018
This contribution describes seven new species of fossil stoneflies from Cretaceous Burmese amber, all of which are dedicated to present and past members of the Rolling Stones. Two species—Petroperla mickjaggeri gen. nov. sp. nov.

Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

Limnology and Oceanography, Volume 70, Issue S2, Page S377-S391, December 2025.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Differences in Thermal Tolerance Between Two Thermally Isolated and Genetically Indistinct Populations of \u3ci\u3eParagnetina Media\u3c/i\u3e (Walker) (Plecoptera: Perlodidae) [PDF]

, 2018
The critical thermal maximum (CTM) of Paragnetina media (Walker) (Plecoptera: Perlodidae) was studied at two sites of the Big Sable River in northwestern Lower Michigan during summer 2013. The sites were separated by ~8 km and differed in temperature by ~

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.

The food of Atlantic salmon Salmo salar L. and brown trout Salmo trutta L. smolts during migration in the Orkla river, Norway

Fauna Norvegica, 1985
Stomach analyses were carried out on 286 Atlantic salmon smolts and 163 brown trout smolts during migration in the river Orkla Central Norway (63°N, 10°E), from 1982 to 1984. Empty stomachs comprised less than 18,4% for salmon and 25,4% for trout.

Molecular phylogeny and diversification timing of the Nemouridae family (Insecta, Plecoptera) in the Japanese Archipelago

bioRxiv, 2018
The generation of the high species diversity of insects in Japan was profoundly influenced by the formation of the Japanese Archipelago. We explored the species diversification and biogeographical history of the Nemouridae family in the Japanese ...

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

Limnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...
