Expanding native species of river macroinvertebrates mainly retained their original niches, with little evidence of niche shifts over the last 25 years. This suggests that species richness in pristine rivers increases due to enhanced ecosystem energy flow, relaxing interspecific competition and allowing it to carry more individuals and species ...

A Scientometric Approach to the Taxonomy of Brazilian Plecoptera: An Overview of Data [PDF]
The order Plecoptera comprises nearly 4,400 species of freshwater insects known for their specific temperature requirements. In Brazil, there are 207 valid extant species, with 172 (83%) being endemic, and particularly the genus Anacroneuria is well ...

Major disturbance events can profoundly influence biodiversity patterns, although the extent to which such shifts are predictable remains poorly understood. We used environmental DNA (eDNA) to compare forested versus recently deforested stream insect communities across disjunct regions of New Zealand, to test for parallel shifts in response to ...

Ecology of the regulated river Storelva in western Norway 50 years after regulation
The river Storelva, situated in Sauda, Rogaland in western Norway has been regulated for hydroelectric power since 1914 and about 80% of the water-flow is transferred through tunnels to the various power stations and then to the fjord.

We conducted a landscape genetics study using mtDNA and SNP markers to examine the connectivity and dispersal of three stream insect species, Coloburiscus humeralis, Zelandobius confusus and Hydropsyche fimbriata, in a fragmented, pasture‐dominated landscape on the North Island of New Zealand.

Macroinvertebrates and water quality: a teaching guide [PDF]
Streams support a diverse community of plants and animals on or in the stream bed. These organisms comprise the benthos. Among the benthos are worms, molluscs, crustaceans, and larval insects.

Abstract Biodiversity underpins the functional integrity of ecosystems. At present, our understanding of the relationship between biodiversity and ecosystem functioning (BEF) is essentially based on manipulative experiments. Compelling data at large spatial scales are scarce, especially for river networks.

Biological report - fish mortality, River Conder, 21.7.79 [PDF]
Following a large scale fish mortality caused by a considerable spillage of a pentachlbrophenol-based disinfectant from a mushroom farm, a biological survey of the river Conder was undertaken on 23.7.79.
