Systematic revision and phylogeny of Paragripopteryx Enderlein, 1909 (Plecoptera: Gripopterygidae) [PDF]

PLoS ONE, 2022
Among the Neotropical gripopterygids, the genusParagripopteryxoccurs along the Brazilian Atlantic coast to Uruguay. Since its first recognition by Enderlein in 1909, the genus underwent a confusing taxonomic history with some combinations. In this study, we aim to reviseParagripopteryxand present the first morphology-based phylogeny for the genus.

Leaf litter breakdown along an elevational gradient in Australian alpine streams. [PDF]

Ecol Evol, 2022
We aimed at understanding how spatial and temporal water temperatures influenced AOM breakdown in alpine streams. Microbial and macroinvertebrate activities were monitored and showed to be elevated at lower elevations and during warmer periods. Climate change induced warming will therefore potentially change alpine stream ecosystem, standing biomass ...

Gripopterygidae (Plecoptera) from Paranapiacaba mountains, southeastern Brazil [PDF]

Annales De Limnologie, 2011
In the present paper, adults of the family Gripopterygidae collected in Paranapiacaba mountains are analyzed, the new species are described and a key to species of this family from this area is presented. Twenty one species in four genera of Gripopterygidae are recorded in Paranapiacaba mountains, Sao Paulo State, Brazil.

Five new species of Tupiperla Froehlich, 1969 (Plecoptera: Gripopterygidae)

Zootaxa, 2019
The stoneflies of the family Gripopterygidae have a Gondwanan distribution (Australian, Neotropical, and Andean regions) and include about 300 species in five recognized subfamilies. The subfamily Gripopteryginae is restricted to the Neotropics and the Andean regions of South America, including 15 genera and about 80 species.

ebony underpins Batesian mimicry in melanic stoneflies

Molecular Ecology, Volume 32, Issue 18, Page 4986-4998, September 2023., 2023
Abstract The evolution of Batesian mimicry – whereby harmless species avoid predation through their resemblance to harmful species – has long intrigued biologists. In rare cases, Batesian mimicry is linked to intraspecific colour variation, in which only some individuals within a population resemble a noxious ‘model’.

Single‐species acute lethal toxicity tests are not predictive of relative population and community effects of two salinity types

Limnology and Oceanography Letters, Volume 8, Issue 1, Page 181-189, February 2023., 2023
Abstract Human‐mediated salinity increases are occurring in freshwaters globally, with consequent negative effects on freshwater biodiversity. Salinity comprises multiple anions and cations. While total concentrations are typically used to infer effects, individual ion concentrations and ion ratios are critical in determining effects.

Freshwater macroinvertebrate traits assessment as complementary to taxonomic information for mining impact detection in the northern Peruvian Andes

Diversity and Distributions, Volume 28, Issue 8, Page 1582-1596, August 2022., 2022
Abstract Aim We studied the distribution of freshwater macroinvertebrate taxa and traits to distinguish ecological gradients among the mining‐controlled and natural headwaters, and rural and urban economic activity influences. Location In 2016’s dry season, macroinvertebrate samples were collected at 40 locations in the Mashcon watershed, northern ...

Development of a flow‐sensitive macroinvertebrate index for Australian rivers

River Research and Applications, Volume 38, Issue 5, Page 846-862, June 2022., 2022
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.

Combining molecular datasets with strongly heterogeneous taxon coverage enlightens the peculiar biogeographic history of stoneflies (Insecta: Plecoptera)

Systematic Entomology, Volume 46, Issue 4, Page 952-967, October 2021., 2021
The biogeographical and phylogenetic patterns of stoneflies were addressed using supertree methods to combine transcriptomic and Sanger sequence data. The ancestors of extant stoneflies originated in the Northern Hemisphere during the Upper Permian and were restricted to this area due to climatic and geographic boundaries until the Lower Jurassic.
