“…() who documented similar patterns for stream macroinvertebrates. Hollingsworth & Vis () studied within‐stream beta diversity in diatoms based on a comparable sampling design to our present design. They concluded that one sample might be sufficient to represent community composition of severely impacted streams, but that for more pristine sites even a two‐riffle sample is inadequate.…”

“…Earlier studies on lotic diatoms have examined patterns in beta diversity mainly at broad regional or continental scales, that is at scales ranging from hundreds to thousands of kilometres (Potapova & Charles, 2002;Soininen, 2004;Astorga et al, 2012) or at very small, within-riffle scales (Passy, 2001;Soininen, 2004). To the best of our knowledge, only one paper has investigated patterns in diatom beta diversity at intermediate scales (Hollingsworth & Vis, 2010). In this study, we used data collected from 10 boreal streams each with 10 surveyed riffle sites.…”

Beta diversity of stream diatoms at two hierarchical spatial scales: implications for biomonitoring

Summary Human‐induced loss of environmental heterogeneity may lead to homogenisation of biological communities. However, environmental heterogeneity is important for sustaining current levels of biodiversity. Hence, more ecological research should be directed on understanding the relationships between beta diversity and environmental heterogeneity. Benthic diatoms are among the most extensively studied taxa of primary producers in streams, yet their beta diversity patterns are not well documented at intermediate spatial scales, that is within and among streams, in a catchment. We tested how well one sampling site represents the total diatom diversity of a stream using 10 boreal streams, each comprising 10 sampled riffles. We also examined variation in diatom community structure at two hierarchical scales, within and among streams. Relationships between diatom beta diversity and environmental heterogeneity were studied using a combination of species accumulation curves, canonical analysis of principal coordinates, tests of homogeneity of dispersions and distance‐based redundancy analysis. We found large variation in community structure within each stream, which indicates thatone sample is not adequate to represent the diatom diversity of an entire stream. The variation in among‐stream diatom community structure was larger than among‐stream habitat heterogeneity. Although no positive relationship between within‐stream diatom beta diversity and environmental heterogeneity was detected, we found that diatom community variation was significantly related to physical habitat structure and, surprisingly, also to grazer abundance. We recommend that more than one sampling site is included in analyses aiming to cover the diatom diversity of a whole stream. This is especially true for pristine sites with high diatom diversity. In addition, we suggest that researchers incorporate physical and biological factors as explanatory variables when monitoring diatoms both at the within‐ and among‐stream scales.

The influence of the fishpond on the chemical composition of the stream was mainly demonstrated by a higher concentration of organic matter and total phosphorus. Altogether, 128 species of algae and cyanobacteria were recorded in the stream. The species richness of phytobenthos per site was very similar. We observed the presence of typical phytoplankton species among the phytobenthos assemblages. Cyanobacteria species (Woronichinia naegeliana) were particularly dominant in the phytoplankton of the fishpond in autumn. Altogether, we identified 164 taxa of benthic macroinvertebrates in running waters of the stream. The structure of macrozoobenthos communities from all localities of the stream indicated good water quality and a low influence of environmental stressors with no negative effects of the fishpond. In total, six fish species were registered in all profiles. The condition of the fish population was mainly influenced by the fishery management of the stream (stocking, angling). Generally, the influence of the discharge water from the fishpond was recognizable in small changes in both chemical and biological variables of the stream.

The aim of the present study was to evaluate the influence of different human activities on water quality and benthos composition in the Ošetnice Stream that is located in the Western Carpathian Mountains. During the whole period of our monitoring, the high concentrations of dissolved oxygen and low content of organic matters were determined. Upstream part of the Ošetnice Stream is affected by long term building activities concerning railway tunnels and by the motorway along the stream that is in winter chemically treated to assure negotiability. Ski area situated close to the stream was used 110 days during the monitored period. Average daily visit was 590 persons. In winter, when road salting was used, concentrations of chlorides, sodium and calcium were noticeably increased in the stream tributaries which had an impact on monitored water parameters. Water quality assessment using macrozoobenthos and phytobenthos indices revealed the environmental state in a range from moderate to good. Decrease of salmonid community in the stream corresponds to start of road use in the year 2002. Salt applied in winter period to ensure road negotiability affected significantly water chemistry of the monitored stream. Deterioration of environmental conditions is mainly due to human activities; nevertheless self-cleaning ability of the stream is high and ensure a fast degradation of pollutants. Thus the biotic communities (except fish) of the Ošetnice Stream have to adapt to changes of the environment within the year.
