Two new species of Sinacroneuria Yang & Yang, 1995 (Plecoptera: Perlidae) from China

open access: yesEuropean Journal of Taxonomy
Two new species of the stonefly genus Sinacroneuria, S. aequalis sp. nov. and S. transversa sp. nov., are described and illustrated from the Fujian and Zhejiang provinces of China. These new taxa are compared with related congeners.

Reliance on blue, green, and brown energy channels drives a shift in the trophic position of riparian spiders

open access: yesEcology, Volume 107, Issue 1, January 2026.
Abstract Understanding the mechanisms shaping food chain length (FCL) has long been central to food web ecology. FCL is a key determinant of stability, energy flow efficiency, and biodiversity maintenance, but there is an ongoing debate about its underlying drivers.

At last, a Pennsylvanian stem-stonefly (Plecoptera) discovered

open access: yesBMC Evolutionary Biology, 2011
Background Stem-relatives of many winged insect orders have been identified among Pennsylvanian fossils (Carboniferous Period). Owing to their presumed 'basal' position in insect phylogeny, stoneflies were expected to occur at this period.

Explainable Multimodal Machine Learning Using Combined Environmental DNA and Biogeographic Features for Ecosystem Biomonitoring

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
The use of environmental DNA (eDNA) as the sole input in current machine learning (ML) practices inherently limits the potential of ML for ecosystem biomonitoring and prediction. Using impact prediction across Switzerland's 163 biomonitoring sites as an example, a multimodal ML workflow combining eDNA and biogeographic data is introduced.

Community structure, life histories and secondary production of stoneflies in two small mountain streams with different degree of forest cover

open access: yesJournal of Limnology, 2015
Our study examines community structure and nymphal biology (life cycles and secondary production) of stoneflies in two adjacent mountain streams with different degree of forest cover in the Prosiečanka River Basin (Chočské Vrchy Mts., West Carpathians ...

The vulnerability of British aquatic insects to climate change

open access: yesKnowledge and Management of Aquatic Ecosystems, 2022
Freshwater ecosystems are particularly at risk from climate change due to the intrinsic link between the physical properties of the water environment and those species that live there. Mayflies, stoneflies and caddisflies are key indicators of the health

The Return of \u3ci\u3eHexagenia\u3c/i\u3e (Ephemeroptera: Ephemeridae) to the Lower Fox River, Wisconsin [PDF]

open access: yes, 2017
Burrowing mayflies (Hexagenia bilineata) were collected in 1991 in the vicinity of the DePere dam on the Fox River, Brown County, Wisconsin. Because Hexagenia mayflies are indicators of good water quality, their emergence from the Fox River is evidence ...

Stoneflies (Plecoptera) of Nevada [PDF]

open access: yesMonographs of the Western North American Naturalist, 2017
Abstract. Stoneflies (Plecoptera) are a dominant group in running freshwaters. We report 104 stonefly species from Nevada. The fauna contains species with Sierra Nevada—Cascade range affinities, few of which penetrate far eastward, and Rocky Mountain species extending to western Nevada.
