Acta 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

The hyporheic zone and its functions: revision and research status in Neotropical regions
Brazilian Journal of BiologyThe hyporheic zone (HZ), as the connecting ecotone between surface- and groundwater, is functionally part of both fluvial and groundwater ecosystems. Its hydrological, chemical, biological and metabolic features are specific of this zone, not belonging ...

Responses of resources and consumers to experimental flow pulses in a temporary Mediterranean stream [PDF]
, 2021 Determining the resistance and resilience of resources and benthic invertebrates connected to instream refuges and species re-colonization in post-flood periods may help to elucidate mechanisms behind community recovery.

Invertebrate Responses to Restoration across Benthic and Hyporheic Stream Compartments [PDF]
, 2021 River restoration is a multi-billion-dollar business, yet it is unclear whether benthic community health, which is routinely monitored, can be used as a proxy for the health of the hyporheos.

Metabolism Modeling in Rivers With Unsteady Flow Conditions and Transient Storage Zones
Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 3, March 2023., 2023 Abstract Whole‐stream metabolism characterizes energy and carbon transformations, thus providing an estimate of the food base and CO2 emission sources from streams and rivers. Metabolism models are generally implemented with a steady flow assumption that does not hold true for many systems with sub‐daily flow variation, such as river sections ...

Quantifying the ecological effects of water abstraction in Alpine streams through flume simulations
Ecohydrology, Volume 15, Issue 6, September 2022., 2022 Abstract Water abstraction by small hydropower plants is a growing human pressure on Alpine stream ecosystems. Using a set of seminatural streamside flumes, we investigated the response of benthic invertebrate communities to a 50% experimental reduction of the natural discharge.

The hyporheic zone as an invertebrate refuge during a fine sediment disturbance event
Ecohydrology, Volume 15, Issue 6, September 2022., 2022 Abstract Subsurface sediments offer an important refuge that support the survival and persistence of river invertebrates during adverse surface conditions. Access to refuges for invertebrates varies with differing hydrological and substrate characteristics, especially the proportion of fine sediment.

Water Resources Research, Volume 58, Issue 3, March 2022., 2022 Abstract Hyporheic zones increase freshwater ecosystem resilience to hydrological extremes and global environmental change. However, current conceptualizations of hyporheic exchange, residence time distributions, and the associated biogeochemical cycling in streambed sediments do not always accurately explain the hydrological and biogeochemical ...
