“…Substrate type is known to be one of the main factors influencing macroinvertebrate richness and community structure (Ward 1992;Townsend et al 2003;Allan & Castillo 2007). In the streams of the Pieniny Mts the proportion of gravel and cobble are most important for mayfly communities as it has been noted by the other studies (Füreder et al 2002;Hieber et al 2005;Effenberger et al 2006). Suitable substrate size determines the occurrence of particular mayfly species (Brittain 1982).…”

“…Moreover, it supplies nutrients and organic matter (litter and wood) to the stream ecosystem (Balestrini et al 2004), and thus has an important role in determining the trophic structure in the stream. Particular emphasis has been placed on the role of riparian vegetation in mountain streams in naturally forested catchments, where it is often the most important factor differentiating macroinvertebrate occurrence in the stream ( Vannote et al 1980;Füreder et al 2002;Krno et al 2007). …”

A study of the species composition of mayfly communities in connection with environmental parameters was made in headwater streams of the Pieniny Mts. The rhithral zone is inhabited maximally by 19 mayfly species. In most of the streams studied the mayfly communities were found to be similar, however the vertical zonation which reflected human impact was visible (NMDS analysis). The main factors responsible for mayfly communities at all the sites studied were stream regulation and organic pollution, followed by type of bottom substrate (pebble and gravel), riparian vegetation (shrubs), pH and water temperature. At undisturbed sites the most important factors were pH, substrate type, distance from the source, current velocity and riparian vegetation (CCA analysis). Analysis of mayfly communities and environmental characteristics in different seasons showed that occurrence of mayfly species varied substantially depending on the season. Only in early spring and autumn do mayfly communities occur which are dependent on many environmental factors, the most significant of which are substrate type, phosphate, distance from source and altitude (CCA analysis).

ABSTRACT1. High climatic sensitivity and lack of significant human impact make alpine river basins important environments for examining hydrological and ecological response to global change.2. This paper is based upon previous and ongoing research within a glacierized, alpine river system (Taillon-Gabie´tous basin, French Pyrenees), which adopts an interdisciplinary approach to investigate the climate-hydrology-ecology cascade. Data are used to advance hypotheses concerning impacts of climate change/variability upon alpine river system hydrology and ecology.3. The snowpacks and glaciers that are the source of Pyrenean streams are climatically sensitive, with glaciers in retreat for most of the historical period. Given anticipated changes in summer airmass frequencies, the volume of meltwater may decrease, the nature and rate of glacier drainage may alter, and the timing of peak snow-and ice-melt may shift. However, rainfall-runoff and groundwater may increase their relative contributions to stream flow.4. The influence of changing water source contributions on physico-chemical habitat and, in turn, on benthic communities is assessed using an alternative alpine stream classification. This model predicts more rapid downstream change in benthic communities in the future as meltwater contributions decline and, at the basin-scale, biodiversity may be reduced owing to less spatiotemporal heterogeneity in water sources contributions and, thus, physico-chemical habitat. However, predictions are complicated by potential changes in biotic interactions with altered species' distributions.5. Integrated, long-term research into the climate-hydrology-ecology cascade in other alpine river basins is vital because interdisciplinary science is fundamental to predicting stream hydrology and ecology under scenarios of future climate/variability, to assessing the utility of alpine river

Life at the Edge: Habitat Condition and Bottom Faunaof Alpine Running Waters

Alpine river systems are fed by glacial icemelt, snowmelt, and groundwater and share common features (e.g., steep gradients, high flow velocities and dynamics) but each source produces a characteristic discharge regime and a distinctive suite of physical and chemical characteristics. The distribution of snow, ice, and groundwater springs varies spatially from stream-reach to catchment scale, resulting in stream segments with characteristics, reflecting the different runoff sources. In recent investigations we have been focusing on the large variety of natural freshwater ecosystems in the Hohe Tauern Nationalpark and, based on hydromorphological conditions at catchment and reach scale, we defined specific river types. Glaciation in the catchment turned out to be a major factor for defining the hydromorphological conditions. Subsequently, we tested the effect of glaciation on the bottom fauna in applying a preliminary set of species traits, indicating strategies and adaptations of resilience and resistance as well as to face environmental harshness. Our results demonstrated the high degree of adaptation of the bottom fauna in alpine streams but especially in glacial streams. As current climate change scenarios propose major impacts at both high altitude and latitudes, considerable changes within the faunal assemblages including species number, densities and the distribution of species traits are to be expected.
