Interactions between fauna and sediment control the breakdown of plant matter in river sediments [PDF]

, 2009
1. A substantial portion of particulate organic matter (POM) is stored in the sediment of rivers and streams. Leaf litter breakdown as an ecosystem process mediated by microorganisms and invertebrates is well documented in surface waters.

An Initial Classification of Neotropical Water Mites (Acari: Hydrachnidia) Based on Habitat Preferences

International Journal of Ecology, Volume 2011, Issue 1, 2011., 2011
Existing classifications of benthic and interstitial freshwater invertebrates are described and discussed. A classification is proposed for southern neotropical (south of latitude S 15) water mites in relation to their life style and habitat preferences. The classification includes planktonic, superficial, benthic, thermal, and subterranean forms.

Evolution of a stream ecosystem in recently deglaciated terrain

, 2011
Climate change and associated glacial recession create new stream habitat that leads to the assembly of new riverine communities through primary succession.

Methodological Evaluation of Riverbed Clogging—Insight From Field Measurements

River Research and Applications, Volume 41, Issue 6, Page 1282-1299, July 2025.
ABSTRACT Clogging of gravel‐bed rivers is a major issue affecting fish and macro‐invertebrate habitats as well as groundwater–river exchanges. River clogging consists mainly of the deposition and infiltration of fine sediments within the bed matrix, which is a natural phenomenon but can be exacerbated by human activities.

The hyporheic zone and its functions: revision and research status in Neotropical regions

Brazilian Journal of Biology
The 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 ...

Hyporheic fauna from interstitial of the Someş River basin (Transylvania, northwestern Romania) [PDF]

, 2009
Biodiversity in hyporheic habitats (interstitial water habitats in river bank sediments) has been studied on Someşul Cald (Warm Someş) and Someşul Rece (Cold Someş) River (north-western Romania, Transylvania), from March to October 2004.

Effect of acidification on leaf litter decomposition in benthic and hyporheic zones of woodland streams [PDF]

, 2012
Anthropogenic acidification has deleterious effects on both structure and functioning of surface water ecosystems. This study examined how it may affect the leaf decomposition rate and the community structure and activity of decomposers in both benthic ...

Principles of Riverscape Health

WIREs Water, Volume 12, Issue 4, July/August 2025.
Healthy riverscapes have (i) space to interact within their valley bottom; (ii) natural flow, sediment, and vegetation regimes appropriate to the biophysical setting and river type; and (iii) structural forcing to support diversity and that creates varied residence times for water, sediment, and vegetation.

Modelling nitrogen and phosphorus loads in a Mediterranean river catchment (La Tordera, NE Spain) [PDF]

, 2011
Human activities have resulted in increased nutrient levels in many rivers all over Europe. Sustainable management of river basins demands an assessment of the causes and consequences of human alteration of nutrient flows, together with an evaluation of ...

Fine sediment on leaves : shredder removal of sediment does not enhance fungal colonisation [PDF]

, 2011
Inorganic fine sediments are easily carried into streams and rivers from disturbed land. These sediments can affect the stream biota, including detritivorous invertebrates (shredders) and impair ecosystem functions, such as leaf litter decomposition.
