Patterns and Processes of Groundwater Invasion by Copepods in the Interior Low Plateaus of the United States

open access: yesActa Carsologica, 2007
The copepod crustacean fauna collected from subterranean habitats, including caves, wells, and the hyporheos of streams in and near the Interior Low Plateaus of the United States is dominated by Cyclopoida, with 39 species, followed by Harpacticoida with

Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]

open access: yes, 2009
Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

Nutrient uptake in a stream affected by hydropower plants: comparison between stream channels and diversion canals [PDF]

open access: yes, 2012
12 páginas, 3 figuras, 4 tablas.Small hydropower plants divert part of the water from wide and physically complex stream channels with active hyporheic areas to narrow and hydraulically simple concrete canals, and thus, might affect nutrient dynamics.

Role of the hyporheic zone in increasing the resilience of mountain streams facing intermittency [PDF]

open access: yes, 2020
5openInternationalItalian coauthor/editorWe investigated the impact of intermittence in previously-perennial Alpine stream reaches, targeting the role of the hyporheic zone in increasing the resilience of these aquatic systems.

Influence of nontrophic interactions between benthic invertebrates on river sediment processes: a microcosm study [PDF]

open access: yes, 2004
The main objective of this study was to measure the impact of benthic invertebrate diversity on river sediment processes. We quantified the effects of interactions between three taxa (asellids, chironomid larvae, and tubificid worms).

Faunal response to benthic and hyporheic sedimentation varies with direction of vertical hydrological exchange [PDF]

open access: yes, 2014
1. Sedimentation and clogging of benthic and hyporheic zone substrates is increasingly being recognised as one of the greatest threats to the ecological integrity of riverine ecosystems globally. This ex-situ study examined the influence of sedimentation

Spatial variability in the hyporheic zone refugium of temporary streams [PDF]

open access: yes, 2011
A key ecological role hypothesized for the hyporheic zone is as a refugium that promotes survival of benthic invertebrates during adverse conditions in the surface stream.

Characterization of the density and body size of a Gammarus pulex (Crustacea: Amphipoda) population in subsurface sediments reflects the sampling technique used [PDF]

open access: yes, 2016
The hyporheic zone and its invertebrate fauna play vital roles in the functioning of lotic ecosystems. However, although sampling invertebrates from subsurface sediments is recognized as challenging, few studies have quantified the effectiveness of ...

Stream ecosystem responses to an extreme rainfall event across multiple catchments in southeast Alaska [PDF]

open access: yes, 2015
Floods are a key component of the flow regime of many rivers and a major structuring force of stream communities. Climate change is predicted to increase the frequency of extreme rainfall (i.e. return intervals > 100 years) leading to extensive flooding,
