Open AccessLong-lasting effects of experimental flow intermittency on alpine stream macroinvertebrates (Val Roseg, Switzerland)
Changing weather patterns and receding glaciers are predicted to increase flow intermittency in alpine streams. If aquatic macroinvertebrate communities largely comprise taxa adapted to perennial flows, an inc...

Mercury levels in sediment, fish and macroinvertebrates of the Boroo River, northern Mongolia, under the legacy of gold mining
Gold mining is currently one of the main anthropogenic sources of mercury in the environment. In this study, the total mercury content was measured in bottom sediments, benthic macroinvertebrates (mayfly larva...

Article
Riparian hunting spiders do not rely on aquatic subsidies from intermittent alpine streams
Drying in alpine streams might decrease aquatic-terrestrial trophic linkages by reducing terrestrial predation on aquatic prey. We tested this hypothesis by investigating whether a common riparian predator (hu...

Effects of an experimental increase in flow intermittency on an alpine stream
Flow intermittency occurs naturally in alpine streams. However, changing rainfall patterns and glacier retreat are predicted to increase the occurrence of flow intermittency in alpine catchments, with largely ...

Functional diversity and community assembly of river invertebrates show globally consistent responses to decreasing glacier cover
Global change threatens invertebrate biodiversity and its central role in numerous ecosystem functions and services. Functional trait analyses have been advocated to uncover global mechanisms behind biodiversi...

Changes in macroinvertebrate trophic structure along a land-use gradient within a lowland stream network
Running waters are among the most threatened ecosystems globally, having altered hydrological regimes, homogenized habitat, and impaired water quality. These multiple stressors impact aquatic biodiversity and ...

Article
Short-term colonization dynamics of macroinvertebrates in restored channelized streams
Macroinvertebrate colonization of restored rivers is a function of dispersal into the restored reach and its suitability for population establishment. To maximize potential for colonization success, spatial co...

Spatio-temporal relationships between habitat types and microbial function of an upland floodplain
Natural floodplains comprise a spatial mosaic of habitat types that vary in successional development. The physical–chemical properties of soils and sediments in these habitats vary spatio-temporally with chang...

Spatio-temporal shifts of macroinvertebrate drift and benthos in headwaters of a retreating glacier
Recent alpine stream studies have aimed to predict biotic responses to changing environmental conditions, hydrological regime and climate, but there is little information on macroinvertebrate drift shifts in ...

Shifts in isotopic signatures of animals with complex life-cycles can complicate conclusions on cross-boundary trophic links
Stable isotopes (13C and 15N) are widely applied in studies of trophic links. We used this method to investigate the contribution of aquatic and terrestrial prey to the diet of riparian predatory arthropods in tw...

Spatial patterns in macroinvertebrate assemblages in surface-flowing waters of a glacially-influenced floodplain
We examined the spatial structure of macroinvertebrate assemblages in surface-flowing waters of a glacially-influenced floodplain. The floodplain main-channel responded longitudinally to changes in hydrology w...

The hydro-morphological index of diversity: a tool for describing habitat heterogeneity in river engineering projects
We present a new hydro-morphological index of diversity (HMID), a tool aimed for use in river engineering projects and firstly developed at gravel-bed streams in Switzerland, but intended for a broader use. We...

Article
Invertebrate and microbial responses to inundation in an ephemeral river reach in New Zealand: effects of preceding dry periods
Inundation marks the shift from a terrestrial ecosystem to an aquatic ecosystem in ephemeral rivers. The forms and rates of responses by aquatic invertebrates and sediment microbes to inundation depend on desi...

Article
Macroinvertebrate diversity in fragmented Alpine streams: implications for freshwater conservation
Lakes and reservoirs disrupt the longitudinal connectivity of streams, considerably affecting benthic macroinvertebrate assemblages and diversity. Changes in assemblage composition within fragments can result ...

Article
Benthic diatoms of an Alpine stream/lake network in Switzerland
We compared the benthic diatom composition of lakes, and lake inlet and outlet streams in a high elevation catchment (∼2600 m a.s.l.) in the Swiss Alps. The catchment consisted of a southern basin mostly fed b...

Longitudinal effects of experimental floods on stream benthos downstream from a large dam
We examined the longitudinal effects of 3 experimental floods on seston, periphyton, and macroinvertebrates in a regulated river downstream from a large reservoir in the Swiss Alps. In addition, suspended orga...

Effects of a multi-year experimental flood regime on macroinvertebrates downstream of a reservoir
We examined the response of stream macroinvertebrates to a multiple-year experimental flood regime downstream of a large reservoir. Benthic samples were collected from the River Spöl prior to the initial flood...
