Microbial community composition of transiently wetted Antarctic Dry Valley soils

Frontiers in Microbiology, 2015
During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DV) become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV ...

Field Experiments of Hyporheic Flow Affected by a Clay Lens

, 2019
As a typical water exchange of surface water and groundwater, hyporheic flow widely exists in streambeds and is significantly affected by the characteristics of sediment and surface water.

Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers

, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed

Thermal heterogeneity in the hyporheic zone of a glacial floodplain

, 2001
We examined the thermal regime of surface and hyporheic waters at three kryal sites and four krenal streams within the channel network of a glacial floodplain. Temperature was continuously measured for 1 year in the surface stream and at sediment depths

Nitrogen circulation in a Mediterranean holm oak forest, La Castanya, Montseny, northeastern Spain [PDF]

Hydrology and Earth System Sciences, 2002
The importance of storm frequency as well as the groundwater and hyporheic inputs on nitrate (NO3-N) and ammonium (NH4-N) levels in stream water were studied in a small perennial Mediterranean catchment, Riera Major, in northeast Spain.

Effects of Benthic Burrows on Hyporheic Exchange

Macrobenthic invertebrates are widely distributed on sediments, and the micro‐morphology such as burrows and sand mounds due to their bioturbation activities can cause substantial changes in hyporheic exchange (HE).

Labile dissolvedorganic carbon supply limits hyporheic denitrification

, 2011
[1] We used an in situ steady state 15N‐labeled nitrate (15NO3−) and acetate (AcO−) well‐to‐wells injection experiment to determine how the availability of labile dissolved organic carbon (DOC) as AcO−influences microbial denitrification in the hyporheic
