Impact of Boulders and Boulder‐Induced Morphology on Oxic Volume of the Hyporheic Zone of Plane‐Bed Rivers

Water Resources Research, Volume 61, Issue 7, July 2025.
Abstract Streambed biogeochemical processes strongly influence riverine water quality and gaseous emissions. These processes depend largely on flow paths through the hyporheic zone (HZ), the streambed volume saturated with stream water. Boulders and other macroroughness elements are known to induce hyporheic flows in gravel‐bed streams.

Shallow Waters, Deep Divergence: Epigean Amphipods Utilize Shallow Hyporheic Habitats in the Western Allegheny Plateau

Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.
Two new species of freshwater amphipods, Crangonyx ipnoecetes n. sp. and Crangonyx furnaricolus n. sp., are described from intermittent bodies of water in Vinton Furnace State Forest (VFSF), Vinton County, Ohio, USA. The descriptions of these species are based on both morphological and molecular analyses, which identify them as only distantly related ...

Dry season refuges, refugia and flow‐regime change in Mediterranean climate streams

Freshwater Biology, Volume 69, Issue 11, Page 1607-1626, November 2024.
Abstract Climate change is causing stream flow regimes to change in many regions globally, including southwestern Australia (SWA) where many perennial streams have switched to intermittent flow regimes. In drier landscapes, ecological refuges and evolutionary refugia will become critical for conserving freshwater biodiversity.

Morpho‐ecospaces, or how to measure biodiversity in a different way

Acta Zoologica, Volume 105, Issue 4, Page 496-513, October 2024.
Abstract The current biodiversity crisis warrants accurate measuring of biodiversity, often achieved by counting species or higher taxonomic units, with morphological or molecular methods. Alternatively, trait‐centred approaches categorise organisms into distinct ecological roles and then count the number of occupied roles to measure biodiversity. Even

Community structure and functioning below the streambed across contrasting geologies [PDF]

, 2018
There is little understanding of the variability in the structure and function of metazoan hyporheic communities across streams draining geologies that weather to produce different pore sizes and, by extension, different hydrological conditions.

Early stages of leaf decomposition are mediated by aquatic fungi in the hyporheic zone of woodland streams [PDF]

, 2010
1. Leaf litter constitutes the major source of organic matter and energy in woodland stream ecosystems. A substantial part of leaf litter entering running waters may be buried in the streambed as a consequence of flooding and sediment movement.

Metabolism of Basque streams measured with incubation chambers [PDF]

, 2010
The metabolism (gross primary production, GPP; respiration, R; and net metabolism, NM) of epilithon was measured by incubating randomly selected cobbles in recirculatory chambers in 21 Basque streams running to the Atlantic coast.

The importance of local processes on river habitat characteristics : a Basque stream case study [PDF]

, 2011
Habitats are the places where organisms live and are defined by a set of abiotic and biotic characteristics that affect individual fitness and community structure.

Characterization of macroinvertebrate communities in the hyporheic zone of river ecosystems reflects the pump-sampling technique used [PDF]

, 2016
The hyporheic zone of river ecosystems provides a habitat for a diverse macroinvertebrate community that makes a vital contribution to ecosystem functioning and biodiversity. However, effective methods for sampling this community have proved difficult to

A review of the processes and effects of droughts and summer floods in rivers and threats due to climate change on current adaptive strategies [PDF]

, 2012
Europe is expected to experience a greater frequency of floods and droughts as precipitation and evapotranspiration patterns are modified by climate change in future.
