  journal={Annales De Limnologie-international Journal of Limnology},
The aim of this research was to investigate three main movement patterns of meiofauna and macrofauna in the riverbed: (1) vertical (downwards) within the interstitial habitat; (2) downstream (negative rheotaxis); (3) upstream (positive rheotaxis). The study was conducted in two headwater streams in the Northern Apennines (Italy), during summer 2009. Sets of traps opening upwards, upstream and downstream to collect, respectively, organisms moving down into the sediment, and organisms with… Expand

Diversity and distribution of benthic and hyporheic fauna in different stream types on an alpine glacial floodplain
Overall, the highly disturbed glacial system hosted a simplified benthos and hyporheos compared to the stable spring system, in agreement with the intermediate disturbance hypothesis. Expand
Is drift the primary process promoting the resilience of river invertebrate communities? A manipulative field experiment in an intermittent alluvial river
Summary In river systems, aquatic invertebrate communities are surprisingly persistent over time and generally recover quickly from disturbances. Drift has long been viewed as the primary processExpand
Alpha and beta diversity of freshwater meiofauna at different spatial scales in a Neotropical lotic system
Community composition results highlighted the contrasting conditions found at the sampling sites, highlighting β3 as an important component of γ diversity across spatial scales, and the effects of different levels of environmental degradation and precipitation affected the ability of the community to recover and recolonise the meiobenthos.

Characterization of Macroinvertebrate Communities in the Hyporheic Zone of River Ecosystems Reflects the Pump-Sampling Technique Used
Bou-Rouch sampling is recommended for most study types, including rapid biomonitoring surveys and studies requiring acquisition of comprehensive taxon lists that include rare taxa. Expand
Role of the Hyporheic Zone in Increasing the Resilience of Mountain Streams Facing Intermittency
We investigated the impact of intermittence in previously-perennial Alpine stream reaches, targeting the role of the hyporheic zone in increasing the resilience of these aquatic systems. We selectedExpand
Ecosystem shifts in Alpine streams under glacier retreat and rock glacier thaw: A review.
An improved understanding of permafrost influence on Alpine headwaters, including the ecology of rock-glacier fed streams, is called for, as these streams are likely to become increasingly important for water supply in many glacier-free Alpine valleys in the near future. Expand
The influence of water quality on hyporheic invertebrate communities in agricultural catchments
Despite knowing that agricultural practices affect river ecosystems, studies on water quality and associated hyporheic invertebrate communities are rare. Yet such knowledge is essential forExpand
Does stream current modify crayfish impacts on a benthic community?
Abstract Non-native crayfish can have impacts on stream communities that are highly variable. A possible explanation for this variability is that crayfish are responding in a context-dependent mannerExpand
Change does not happen overnight: a case study on stream macroinvertebrates
This research, and future studies on different conditions and geographic areas, will contribute knowledge on stream macroinvertebrate diel activity, and provide useful information about efficient sampling strategies. Expand
The influence of environmental and spatial factors on benthic invertebrate metacommunities differing in size and dispersal mode
The study showed that dispersal processes are crucial in shaping benthic communities along streams albeit the relatively small sampling area (max. distance between sampling sites: 2 km), and demonstrated the role played by connectivity in determining species distribution patterns in river systems.

Colonisation patterns and vertical movements of stream invertebrates in the interstitial zone: a case study in the Apennines, NW Italy
The interstitial assemblages differed markedly from the streambed communities in both composition and functional organisation, with more collector-gatherers and predators in the interstitial zone and more filterers and scrapers in the natural riverbed. Expand
Field experiments on colonization and movements of stream invertebrates in an Apennine river (Visone, NW Italy)
Macroinvertebrates continuously redistribute themselves in the riverbed. A knowledge of the colonization mechanisms and movement patterns is very important for an understanding of processes ofExpand
Relative importance of surface and subsurface movement on benthic community recovery in the Makaretu River, North Island, New Zealand
Abstract Colonisation of macroinvertebrates following changes to the stream environment occurs rapidly through drift, oviposition, lateral movement, and vertical migration. To assess the influence ofExpand
The upstream/downstream movement paradox of lotic invertebrates: quantitative evidence from a Welsh mountain stream
Downstream displacement of the most abundant non-insect species, Gammarus pulex, was quite considerable at all three sites, however, at several times during the year the numbers moving upstream approached or exceeded those drifting. Expand

We studied the effects of an engineered flow disturbance on meiofauna (45-500 μm) in an intermittent north Texas prairie stream. As part of an interbasin water-transfer project, water is beingExpand
Responses of Hyporheic Meiofauna to Habitat Manipulation
Interactions between interstitial meiofauna and physicochemical parameters of the hyporheic zone were examined via an in situ experiment on the Speed River, Ontario. The manipulation comprisedExpand
Assessing small-scale directional movements of benthic invertebrates in streams by using a multidirectional cage trap
First field tests show that the MDC-Trap is suitable to characterize small-scale movements of invertebrates in gravel streams, and net longitudinal movement was in the downstream direction for most species, although the taxon-specific patterns varied considerably. Expand
Upstream-downstream movements of aquatic invertebrates in a Rocky Mountain stream
Analysis of size classes based on head capsule width for the mayfly Baetis tricaudatus showed significantly smaller size in stationary individuals compared with moving individuals in the population and revealed that nymphs moving during the day were smaller than those moving at night. Expand

Nonlinear regression analysis indicated a significant relationship between amounts of interstitial sediment entering the pipes and abundances of macrofauna and meiofauna in the hyporheic zone of a gravel stream. Expand
