The floodplain index : a new approach for assessing the ecological status of river/floodplain systems according to the EU Water Framework Directive
A new method was developed to assess the ecological status of river/floodplain-systems. The approach is based on the requirements of biological assessment laid down in the EU Water FrameworkExpand

Ecological integrity of river–floodplain systems—assessment by dragonfly surveys (Insecta: Odonata)
Dragonflies are reliable indicators of the ecological quality of land-water ecotones, habitat heterogeneity and the hydrological dynamics of water bodies. In recent years, surveys of dragonflyExpand

Phenology and the influence of meteorological parameters on the catching success of light-trapping for Trichoptera
SUMMARY. 1. Adult Trichoptera were caught for 1 year (February 1989-March 1990) on the banks of the Danube at Bad Deutsch Altenburg, Lower Austria, using a Jermy-type light trap. The blacklight tubeExpand

Grazers, shredders and filtering carnivores--the evolution of feeding ecology in Drusinae (Trichoptera: Limnephilidae): insights from a molecular phylogeny.
We examined the phylogenetic relationships between species and genera within the caddisfly subfamily Drusinae (Trichoptera: Limnephilidae) using sequence data from two mitochondrial loci (cytochromeExpand

Flow history explains temporal and spatial variation of carbon fractionation in stream periphyton
We investigated factors that contribute to isotopic carbon fractionation in periphytic biofilms in a human-altered headwater stream with a flashy hydrograph. Water velocity had an important effect onExpand

Abundance and microhabitats of freshwater sponges (Spongillidae) in a Danubean floodplain in Austria
Summary 1. This study examined the abundance and distribution of freshwater sponges (Spongillidae) at 32 sites in a floodplain on the Danube within the ‘Donau-Auen’ National Park east of Vienna,Expand

The drifting of invertebrates and particulate organic matter in an Austrian mountain brook
SUMMARY 1. The drift of organisms and particulate organic matter in a calcareous mountain brook near Lunz, Lower Austria, was investigated for 1 year. Five sets of three drift nets (sampling atExpand

Allochthonous Input of Coarse Particulate Organic Matter (CPOM) in a First to Fourth Order Austrian Forest Stream
The allochthonous input of coarse particulate organic matter (CPOM) at the Mauerbach, a low order Austrian forest brook, was investigated from October 1990 to November 1991. Annual input rates rangedExpand

Integrative taxonomy by molecular species delimitation: multi-locus data corroborate a new species of Balkan Drusinae micro-endemics
BackgroundTaxonomy offers precise species identification and delimitation and thus provides basic information for biological research, e.g. through assessment of species richness. The importance ofExpand

Vertical Distribution of Benthic Macroinvertebrates in Riffles versus Deep Runs with Differing Contents of Fine Sediments (Weidlingbach, Austria)
Due to the erosiveness of their sediments, sandstone streams transport high loads of fine particles. The catchment of the Weidlingbach, a 12 km long tributary of the Danube northwest of Vienna, isExpand
