Evaluation of Fish and Macroinvertebrate Indices of Biotic Integrity in the Bioassessment of the Illinois River Basin [PDF]

, 2010
Evaluating performances of the fish and invertebrate Indices of Biotic Integrity (IBIs) for a region is important to maintain rigorous assessment of the environmental quality of streams, especially with increasing urbanization. Timing of the assessment

Extracting Additional Information From Biotic Index Samples [PDF]

, 2017
Macroinvertebrates were collected from a small midwestern stream over a 3-year period as part of a non-point source pollution study. Temporal and spatial variability in standard biotic index values (BIs) were computed and compared with variability ...

Artificial light at night and invasive signal crayfish alter aquatic‐terrestrial food webs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Resource flows across aquatic‐terrestrial boundaries are increasingly affected by multiple stressors, such as artificial light at night (ALAN) and aquatic invasive species, which can alter the availability of resources for consumers.

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]

, 2011
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Benthic macroinvertebrates in the Paranapanema reservoir cascade (southeast Brazil) [PDF]

Brazilian Journal of Biology, 2008
In this study, the composition, specific richness and abundance of benthic macroinvertebrates (<250 µm) from sediments of eight reservoirs of the Paranapanema River (southeast Brazil), as well as from the main tributaries (Taquari, Pardo and Tibagi) and the mouth zone into the Paraná River were analyzed. Nineteen points distributed along 700 km were

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Functional traits drive the inter-annual differences in the diversity of benthic macroinvertebrate communities associated with agricultural ditches

Journal of Freshwater Ecology
Ditches are a key feature of the agricultural landscape, especially in relation to rice cultivation. Despite being affected by anthropogenic pressures in terms of flow regulation and channelisation, they can play an important role as habitats for aquatic

Are the effects of an invasive crayfish on lake littoral macroinvertebrate communities consistent over time?

Knowledge and Management of Aquatic Ecosystems, 2016
Management of invasive species requires assessment of their effects on recipient ecosystems. However, impact assessment of invasive species commonly lacks a long-term perspective which can potentially lead to false conclusions.

Macroinvertebrates, Heavy Metals and PAHs in Urban Watercourses [PDF]

, 2001
Good quality stream water and sediments are crucial for the support of healthy stream flora and fauna but urban runoff degrades watercourses leaving a legacy of pollution in the stream sediments.
