“…Their absence is related to low discharge (abstraction) and high water temperatures. This change in the benthic composition has been already observed in other river systems, where anthropogenic impacts were most evident [49][50][51][52].…”

Changes in lotic benthic macroinvertebrate assemblages along the transboundary Axios-Vardar River (Greece -Former Yugoslavian Republic of Macedonia) were examined in order to identify major anthropogenic impacts correlated to the benthic community composition during the low flow season. Macrozoobenthos and water samples were collected from 21 sites during summer 2000 and beginning of autumn 2001. Parallel to sampling, the recording of the physical structure of the sites took place using the River Habitat Survey (RHS) method. The multivariate techniques of FUZZY and Canonical Correspondence Analysis (CCA), as well as the Hellenic biotic score (HES) and the habitat quality scores (HMS, HQA) were applied to the data. Total dissolved solids and total suspended solids were found to be the primary factors affecting the structure of the observed communities. Additionally, species composition responded to anthropogenic activities, e. g. untreated sewage effluents, industrial discharges, agricultural runoff, intense water abstraction and impoundment. As expected, macrozoobenthos community composition shifted from sensitive to tolerant taxa where human impacts were most evident.

“…The role of wetlands as sinks for metals and macronutrients from roads has also been much researched (e.g. Yousef, Baker & Hvitved‐Jacobsen, 1996). This is an area of possible conflict; on one hand there are attempts to avoid pollution of wetlands and on the other hand there are wetlands being used as pollution sinks.…”

This survey of the literature on the ecological effects of roads and traffic revealed many articles published over many years in peer reviewed journals. There has also been a growing number of reports on the ecological effects of roads produced by government authorities. Whereas few reports have been published on assessing the ecological impacts, there has been a rapidly growing number of reports on methods for mitigation. Gaps in research include the effects of heavy metal accumulation and the processes and effects resulting from habitat fragmentation. There is a need to assess the effectiveness of underpasses and tunnels and the nature and functioning of buffer zones. A literature database has been assembled and is being updated.

“…Benthic invertebrates are considered to be good indicators of water quality last but not least because of their wide sensitivity variation towards contaminants and their relative immobility [6,7,28]. Point-pollution sources and diffuse loads of agricultural runoff affect macrobenthos communities and shift community composition from sensitive to tolerant taxa [6,7].…”

In the present study, the water quality of Kalamas river (NW Greece) was evaluated using Einschätzung der Wasser-und Habitat-Beschaffenheit eines mediterranen Flusses (Kalamas, Epirus, Hellas) in Übereinstimmung mit der EU-WasserrahmenrichtlinieDie Wasserbeschaffenheit des Kalamas River (Nordwest-Griechenland) wird auf der Basis physikalisch-chemischer und hydromorphologischer Parameter und der benthischen Makrofauna dargestellt. Statistische Analysen (Cluster-und FUZZY-Analysen) und zwei biotische Indices (NMWP und HS) werden zur Klassifizierung der Probestellen hinsichtlich der Wasserbeschaffenheit genutzt. Danach weist der Kalamas River an allen Stellen eine sehr gute bis gute Wasserbeschaffenheit auf, ausgenommen der unterste, nahe dem Delta gelegene Abschnitt, der deutlich oder signifikant verunreinigt ist. Die Gewässerbeschaf-fenheit scheint während der Niedrigwasserperiode schlechter zu sein als zu Zeiten höherer Durchflüsse. Die ökologischen Parameter (hydromorphologische, chemische und biologische), die für diese integrierte Bewertung verwendet wurden, entsprechen denjenigen, die von der Wasserrahmenrichtlinie 2000/60 der EU für ein effizientes Monitoring der Fließ-gewässer vorgeschlagen werden.
