Evaluation of a pump method for unbiased sampling of stream hyporheos
Hydrobiologia, 2014 The applicability of a pump method for field surveys of hyporheos was investigated for taxon-specific collection bias by comparing a pump method with a core method in a shore area of the lower reach of Kizu River in Japan. A sampling bias index for the first 10 l of pump samples compared with 10 l hyporheic water (equivalent) core samples showed that ...

Effects of a depositional flood event on the hyporheos of a New Zealand stream
Fundamental and Applied Limnology, 2010 Abstract: We investigated the effects of a rare depositional fl ood (return period about 5 years) on the hyporheos of a fl ood-prone river in southern New Zealand. The fl ood deposited 15–40 cm of new sediment across most of the 42-m study site. On four occasions after the fl ood (4 d, 17 d, 35 d, 49 d), pump samples (1 L volume) were col-lected for ...

Archiv Für Hydrobiologie, 2003 We examined the influence of groundwater upwelling on the distribution of the hyporheic fauna in a 2.6-km long glacial flood plain, the downstream part of which behaved as a major groundwater upwelling zone. Hyporheic water and invertebrates were collected during the four different phases of the expansion-contraction cycle at a depth of 30cm in the bed

Science of the Total Environment, 2014 Streambed colmation by fine sediment, e.g. the deposition, accumulation and storage of fines in the substrate, is known to have severe effects on invertebrate assemblages in both the benthic and hyporheic zones but the changes in biological attributes of invertebrate assemblages related to colmation have never been considered simultaneously for these ...

Applicability of environmental DNA metabarcoding for the hyporheic zone of a stream bed [PDF]
Environmental DNA, 2023 To understand whole riverine biodiversity, including hyporheric zones, it is necessary to develop a method to easily and accurately detect hyporheos communities in hyporheic zones, which currently remains poorly understood. Using eDNA metabarcoding for cytochrome‐c oxidase subunit I (COI) regions, we successfully detected various hyporheos and benthos ...

Influence of land use on hyporheos in catchment streams of the Velka Fatra Mts
Biologia (Poland), 2011 The historical influence of landscape on the quantitative variables and a special group of hyporheos in streams with similar origin but different catchment landscapes and forest management was studied. The study was conducted in two streams: (i) a preserved forested natural stream where critical ecosystem processes were unaltered by human activities ...

Hydrology and the Distribution of Hyporheos: Perspectives from a Mesic River and a Desert Stream
Journal of the North American Benthological Society, 1993Our understanding of spatial and temporal dynamics of the distribution of the hyporheos can be considerably enhanced by an appreciation of surface-hyporheic hydrologic exchange. We illustrate this relationship using two case studies from very different lotic ecosystems: a large mesic river in France and an intermittent desert stream in Arizona. In both
