“…This finding is consistent with the observation of Chappuis et al (2014) who found that Catalonian reservoirs maintain higher number of macrophyte species than ponds. Schmera and Baur (2011) found that macroinvertebrate diversity of artificial lowland and natural streams were almost identical in the Pannon Ecoregion. In fact, Schmera and Baur (2011) explained their results with a more abundant aquatic vegetation of artificial watercourses due to constant human perturbation.…”

a b s t r a c tWe examined the distribution of submerged and emergent macrophyte species and the entire macrophyte community within and between five lake types (highland reservoirs, alkali lakes, large shallow lakes, small to medium sized shallow lakes, marshes) in the Pannon Ecoregion, Hungary. The lowest submerged, emergent and total species richness was found in alkali lakes. The highest submerged macrophyte richness was in small to medium sized lakes, while the highest emergent macrophyte species richness was in reservoirs, small to medium sized lakes, and marshes. The values of within-lake type beta diversity were generally lower than the values of alpha diversity, especially for submerged macrophytes, indicating between site homogeneity in species composition within the lake types. Emergent macrophyte communities contributed the most to within and between lake type diversity and total (gamma) diversity. Canonical correspondence analyses showed that the main environmental variables which influenced the distribution of submerged macrophytes were conductivity, Secchi transparency and water nitrogen contents. For emergent macrophytes conductivity, lake width, altitude and water depth proved to be the most influential variables. Our results contribute to the knowledge of large-scale distribution of macrophytes in the Pannon Ecoregion and to the identification of conservation value of lakes using macrophytes. The results support the importance of small lakes and artificial lakes in the conservation of macrophyte diversity compared to large and natural lakes in the Pannon Ecoregion.

“…). For distinguishing among the habitat types, we used the map and typological system of Hungarian running waters, which distinguishes different running water types based on catchment size, altitude and substrate characteristics (see also Erős, ; Schmera & Baur, ). The criteria and the resulting classes correspond to the typological system recommended by the Water Framework Directive of the European Union, and are also frequently used in bioassessment studies (e.g.…”

Effect of landscape context on fish metacommunity structuring in stream networks

This manuscript is contextually identical with the following published paper:Erős, T., Takács, P., Specziár, A., Schmera, D., Sály, P (2017 2. We examined the role of environmental selection (niche based species sorting), dispersal and drift (i.e. stochastic changes in species abundance) mechanisms on the structuring of fish metacommunities in riverscapes. We used a hierarchical design and examined metacommunity structuring 1) in individual running water habitat types, namely highland streams, lowland streams, highland rivers, and lowland rivers, 2) in landscape types, where patterns in highland and in lowland types were examined separately, and 3) at the level of the whole riverscape, where samples from all running water types were pooled. Elements of metacommunity structure (EMS) analysis, community-environmental relationships in redundancy analysis, and decay of community similarity with distance (distance decay)complemented with partial Mantel tests were used to reveal the mechanisms behind the observed patterns.3. Both the EMS framework and community-environment relationships revealed the prevalent role of selection (niche based species sorting mechanisms) on fish metacommunity structuring, although stochastic variability also influenced the results. Metacommunity structures reflecting niche based mechanisms (Clementsian or Quasi-Clementsian) were observed at higher hierarchical levels (i.e. at the riverscape and the landscape type levels), while Quasi-Clementsian or random patterns were found within single running water types.4. Distance decay relationships indicated that dispersal limitation did not clearly affect metacommunity structuring in any combination of running water types. Partial Mantel testsshowed that some part of the variation in distance decay could be explained by the correlation between environmental variables and fish assemblage structure in some habitat types, which further suggests the importance of niche based mechanisms in metacommunity structuring.5. Our study shows that different metacommunity structures can arise in a hierarchy of habitat types in riverscapes, and niche based species sorting mechanisms are more influential in their structuring than dispersal ones. Landscape classifications are useful for a better understanding of the structuring of metacommunities in both the freshwater and the terrestrial realm.

“…At each section (upstream, road crossings, downstream) and sampling date (October 2016, April 2017 and July 2017), we took 3 replicate three-minute samples covering most microhabitats present in the section. Samples were kept separately and preserved in 70% ethanol, returned to the laboratory on the same day and identified to the lowest possible taxonomic level (usually species) according to the relevant references (Soós 1957(Soós , 1963Richnovszky and Pintér 1979;Savage 1989;Csabai 2000;Csabai et al 2002;Eiseler 2005;Kontschán et al 2006;Waringer and Graf 2011;Borza 2012;Ambrus et al 2018). We followed the taxonomical nomenclature of the Fauna Europaea Web Service (de Jong et al 2014).…”

The effects of road crossings on stream macro-invertebrate diversity

Although it is well known that the increasing size of the human population has a negative effect on freshwater biodiversity, the subject of whether or how the intersection of roads and streams (hereafter road crossings) influence the diversity of stream macroinvertebrates is under-researched. To fill this gap in our knowledge, we collected stream macro-invertebrates from road crossings (bridges and culverts) and compared their diversity with upstream and downstream sections. We found that road crossings had negative effects on the richness and abundance of native macro-invertebrates, as well as on the number of protected taxa. Our results showed also that alien individuals were more abundant at road crossings. These findings support the assumption that road crossings contribute to the spread of alien species. The assessment of environmental variables indicated that road crossings caused habitat modifications, and based on these it can be assumed that habitat modifications and associated phenomena (e.g. pollutants and storm events) were the major drivers of the observed patterns in biodiversity. Our results fill a knowledge gap and contribute to the deeper understanding of the effect of road crossings on freshwater biodiversity.
