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

open access: yesPLoS ONE, 2022
Among the Neotropical gripopterygids, the genus Paragripopteryx occurs 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.

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

open access: yesEcol 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 ...

ebony underpins Batesian mimicry in melanic stoneflies

open access: yesMolecular 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

open access: yesLimnology 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

open access: yesDiversity 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

open access: yesRiver 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.
