The EU Water Framework Directive (WFD) is in need of a practical method and index suitable for comparing the ecological status of invertebrate fauna in rivers throughout Europe. The uncertainties that characterize lotic sampling methods can be omitted by increasing sampling effort up to a species detection probability threshold. We describe a statistical model which provides the background for ...

Water quality of the Babai River was assessed through surveying the aquatic invertebrate populations. Study was carried out at Royal Bardia National Park to observe the effect of irrigation dam on water quality through observing the aquatic benthic macro invertebrate’s composition and abundance. The Nepalese Biotic Score (NEPBIOS) method has been used for the biological water quality assessment...

Anthropogenic activity is currently leading to dramatic transformations of ecosystems and losses of biodiversity. The recognition that these ecosystems provide services that are essential for human well-being has led to a major interest in the forms of the biodiversity-ecosystem functioning relationship. However, there is a lack of studies examining the impact of climate change on these relatio...

The direct effects of a Virginia trout farm on benthic macroinvertebrates were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring and from effluent both above and below a sedimentation basin. Onsite mesocosms were constructed to expose previously colonized artificial substrates to the same tr...

Understanding factors that structure regional biodiversity is important for linking ecological and biogeographic processes. Our objective was to explore regional patterns in riverine benthic invertebrate assemblages in relation to their broad positioning along the river network and examine differences in composition, biodiversity (alpha and beta diversity), and environmental drivers. We up-scal...

Todetermine useful metrics for assessing streamwater quality in the Southeastern Coastal Plain, we examined differences among two buffered and three unbuffered streams in an agricultural landscape in southwestern Georgia. Potential indicators included amphibian diversity and abundance, aquatic macroinvertebrate populations, riparian vegetative structure, water quality, and stream physical param...
