1. Studies of hyporheic microbial ecology have suggested an important role for hyporheic microbial processes in stream ecosystem functioning. Using evidence from microbial communities in other aquatic habitats, some predictions are made concerning the diversity of microbial types and microbial processes likely to occur in the hyporheic zone, and the relative importance of these various types to the hyporheic ecosystem. 2. It is predicted that the biofilm growth form of interstitial micro… 

The influence of invertebrate and microbial cross-community interactions on the nitrate removal function in the hyporheic zone

This PhD study aims to understand how the biodiversity influences the water purification processes in the hyporheic zone of running water, as an important regulating service that reduces the quantity

Influence of hyporheic zone characteristics on the structure and activity of microbial assemblages

Summary The hyporheic zone is a pivotal environment for biogeochemical processes in riverine ecosystems. However, the responses of hyporheic microbial assemblage structure and activity to

The Molecular Ecology of Hyporheic Zones: Characterization of Dissolved Organic Matter and Bacterial Communities in Contrasting Stream Ecosystems

The aims of this thesis were to characterize the molecular ecology of the hyporheic zone – between dissolved organic matter (DOM) and microbes – and to test whether seasonal and spatial patterns

A Review of the Hyporheic Zone, Stream Restoration, and Means to Enhance Denitrification

The hyporheic zone is the subsurface area below and adjacent to a stream where groundwater mixes with stream water, through vertical, lateral, and longitudinal flows. The hyporheic zone connects the

Influence of macroinvertebrates on physico‐chemical and microbial processes in hyporheic sediments

The objective of this study was to measure the effects of invertebrates on the physical characteristics and microbial processes in hyporheic sediments. We investigated the impacts of an assemblage of

A River's Liver – Microbial Processes within the Hyporheic Zone of a Large Lowland River

Little is known on microbial activities in the sediments of large lowland rivers despite of their potentially high influence on biogeochemical budgets. Based on field measurements in a variety of

Is the Hyporheic Zone Relevant beyond the Scientific Community?

Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river

Impact of hyporheic zones on nutrient dynamics

Riverine sediments play a fundamental role within the fluvial system, since they represent potential removal zones of stream-borne pollutants and, in particular, nutrients derived by anthropogenic

Bacterial community dynamics in the hyporheic zone of an intermittent stream

It is shown that sediments remained saturated despite months of drought and limited hydrologic connectivity, suggesting that bacteria use hyporheic sediments as a type of refuge from dessication, transported through hydrologically connected pore spaces.

A case study of hyporheic research in a northern Michigan river is presented to illustrate some potential effects of subsurface hydrology on microbial ecology and generated several hypotheses for future research.

Nitrification in the Hyporheic Zone of a Desert Stream Ecosystem

Nitrification in the hyporheic zone of Sycamore Creek, a Sonoran Desert stream, was examined, focusing on the association between respiration and nitrate production. Subsurface respiration in

The ecological significance of exchange processes between rivers and groundwater

1. This review focuses on the connectivity between river and groundwater ecosystems, viewing them as linked components of a hydrological continuum. Ecological processes that maintain the integrity of

Metabolism of streamwater dissolved organic carbon in the shallow hyporheic zone

The supply of streamwater-derived DOC is a significant source of C for hyporheic sediment microorganisms, and these organisms are capable of using about half the DOC contained in streamwater.

Monitoring Biotic And Abiotic Processes Across The Hyporheic/Groundwater Interface

ABSTRACT:A new in situ sampling technique, use of a colonization corer, was used to collect subsurface chemical, biological, and hydrogeological data and thereby monitor processes at the

Patterns of hydrological exchange and nutrient transformation in the hyporheic zone of a gravel‐bottom stream: examining terrestrial—aquatic linkages

SUMMARY 1 The terrestrial-aquatic interface beneath a riparian corridor was investigated as a region of hydrological and biological control of nutrient flux. Subsurface flow paths were defined from

The occurrence of benthos deep in the substratum of a stream

Summary 1 The vertical distribution of the benthic fauna of the Speed River, Ontario, was studied over a 13-month period from October 1970 to October 1971. Various physical and chemical

Linkages between organic matter mineralization and denitrification in eight riparian wetlands

Denitrification (N2 production) and oxygen consumption rates were measured at ambient field nitrate concentrations during summer in sediments from eight wetlands (mixed hardwood swamps, cedar swamps,

Groundwater nitrogen dynamics at the terrestrial-lotic interface of a small catchment in the Central Amazon basin

Processes operating at the terrestrial-lotic interface may significantly alter dissolved nitrogen concentrations in groundwater as a result of shifting redox conditions and microbial communities. We

Denitrification in river sediments: relationship between process rate and properties of water and sediment

1. A survey was made of denitrification and nitrous oxide (N2O) production in river sediments at fifty sites in north-east England during one season in order to investigate the relationship between
