Biomonitoring of intermittent rivers and ephemeral streams in Europe: Current practice and priorities to enhance ecological status assessments.
The results of a survey completed by representatives from 20 European countries to identify current challenges to IRES status assessment, examples of best practice, and priorities for future research are reported.
Global patterns and drivers of ecosystem functioning in rivers and riparian zones
It is found that Earth’s biomes have distinct carbon processing signatures, and slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes.
Current velocity and food supply as factors affecting the composition of macroinvertebrates in bryophyte habitats in karst running water
Regression analysis suggested that macroinvertebrate density increased in faster water flow conditions associated with a decrease in bryophyte biomass, CPOM and FPOM, and an increase of UPOM.
Environmental drivers of biotic traits and phenology patterns of Diptera assemblages in karst springs: The role of canopy uncovered
It is concluded that at springs with similar water characteristics, canopy coverage is the main driver of Diptera assemblage structure, with water velocity as a complementary factor, andstrate and other physicochemical factors seem less important.
Environmental control of emergence patterns: Case study of changes in hourly and daily emergence of aquatic insects at constant and variable water temperatures
New insight is given into the complexity of relationships between aquatic insect emergence patterns and environmental drivers, and light and weather conditions trigger emergence of most insects under constant water temperature conditions, while temperature is a dominant trigger at variable water temperature habitat.
The impact of aquatic macrophyte (Salix sp. and Cladium mariscus (L.) Pohl.) removal on habitat conditions and macroinvertebrates of tufa barriers (Plitvice Lakes, Croatia)
The effects of aquatic macrophyte (willows and sawgrass) removal on flow velocity, tufa deposition, POM dynamics, and macroinvertebrate community structure were studied in the tufa barrier habitats
Calcite deposition in karst waters is promoted by leaf litter breakdown and vice versa
Plant litter breakdown, an important process for energy and matter flows in freshwater eco- systems, has been extensively studied except in the karst (and calcite depositing) habitats. The aim of
Environmental drivers influencing stonefly assemblages along a longitudinal gradient in karst lotic habitats
Stoneflies are among the most sensitive aquatic insect taxa and therefore arguably the best indicator of the excellent, i.e. pristine, ecological status of surface streams. Karst habitats are one of
The Role of Flow Velocity in the Vertical Distribution of Particulate Organic Matter on Moss-covered Travertine Barriers of the Plitvice Lakes (Croatia)
We investigated the distribution patterns of particulate organic matter (POM) on travertine barriers in respect to flow velocity. Research was conducted on the barrage-lake system of the Plitvice
Simuliid silk pads enhance tufa deposition
It is concluded that low winter temperature inhibited intensive calcite precipitation so tufa deposition during winter time happened mainly by trapping and binding microcrystalline calcite, causing a poorer periphyton development and a lesser accumulation of calcite crystals.
