Stoneflies (Plecoptera: Perlidae) of Nicaragua [PDF]
Abstract Neotropical Plecoptera represent an interesting subject of study, for their phylogenetic, biogeographical and ecological importance. The Plecopterofauna of a large portion of the Neotropics is represented by only one genus of Perlidae, Anacroneuria Klapalek.

Currently, a total of 267 stonefly species are known for Canada. The biodiversity hotspot of Canadian stoneflies is British Columbia with at least 138 species, nearly 52% of all species known from Canada. Four families, the Perlodidae, Capniidae, Chloroperlidae, and Nemouridae, contain nearly 75% of all species known to occur in Canada. The family with

The species of Tibetisoperla (Plecoptera: Perlodidae) [PDF]
Two new species of the hitherto monotypic Tibetisoperla Huo & Du, 2021, T. elongata sp. nov., T. sclerotica sp. nov., are described, illustrated and compared with the type species and other Isoperlinae. Tibetisoperla and T. wangluyui Huo & Du, 2021 are newly recorded for Qinghai Province.

Substrate size modifies stream grazer–biofilm interactions in the presence of invertivorous fish
Abstract When herbivore abundance is controlled by predators there may be an indirect positive effect on primary producers due to reduced grazing pressure, but the potential of predation refuges to modify such trophic cascades has rarely been studied.

Effects of water temperature on freshwater macroinvertebrates: a systematic review
ABSTRACT Water temperature is one of the main abiotic factors affecting the structure and functioning of aquatic ecosystems and its alteration can have important effects on biological communities. Macroinvertebrates are excellent bio‐indicators and have been used for decades to assess the status of aquatic ecosystems as a result of environmental ...

Abstract Worldwide, riparian zones of many intermittent rivers and ephemeral streams (IRES) have been severely degraded. However, compared with perennially flowing waters, there have been few restoration efforts (e.g., revegetation, livestock removal) to halt or reverse this degradation.

The cumulative impacts of anthropogenic stressors vary markedly along environmental gradients
When stressors act together, their cumulative effects on biodiversity can be amplified or dampened if they interact with each other. Understanding where and how stressors interact is thus central to managing their impact. Here we show that both the interaction and combined effect of two stressors, salinity and turbidity, on freshwater biodiversity vary

ORDER PLECOPTERA Respiration in stonefly naiads via gills has been studied for decades, partly because of the significance of stoneflies as indicators of water quality. Two plecopteran specimens were scanned, one from Perlodidae and one from Nemouridae.

Acroneuria lycorias (Boreal Stonefly, Plecoptera: Perlidae) Emergence Behaviors Discovered in Pinus strobus Canopy [PDF]
Species of Plecoptera, or stoneflies, are known to use vertical emergence supports, and researchers believe many species of Plecoptera exploit arboreal habitats during emergence.

A Checklist of the Stoneflies, or Plecoptera, of Indiana [PDF]
Examination of specimens and published records has indicated the presence of 61 species of Plecoptera in Indiana. Annotations include the recognition of another 14 species which should eventually be taken within the state, references to species keys and ...
