Benthic Macroinvertebrate Multimetric Index for River (BMIR): Development of a multimetric index based on benthic macroinvertebrates for rivers in Türkiye

open access: yesTurkish Journal of Water Science and Management, 2023
Stream types determined according to altitude, slope and alkalinity in six different hydrobiogeographic regions of Türkiye were taken as the basis of the study. In line with the European Water Framework Directive, a macroinvertebrate based multimetric method was tested for Turkish rivers as a potential assessment.

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Spatial distribution of benthic macroinvertebrates in the Erhai basin of southwestern China

open access: yes, 2012
The macroinvertebrate communities and relationships with environmental variables were characterized in the Erhai basin by sampling at 44 sites. Among the 76 taxa observed, Baetis sp., Tubificidae, Simulium sp., Eukiefferiella sp., Gammarus sp.

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Altitudinal distribution limits of aquatic macroinvertebrates: an experimental test in a tropical alpine stream.

open access: yes, 2015
Temperature and oxygen are recognised as the main drivers of altitudinal limits of species distributions. However, the two factors are linked, and both decrease with altitude, why their effects are difficult to disentangle.
