“…In contrast, under lentic conditions, these taxa tend to decrease and tolerant taxa become dominant in the community (Coimbra et al, 1996). As a result of this dynamic (lentic versus lotic), an annual temporal pattern of macroinvertebrate community composition is observed.…”

“…In Mediterranean streams, the assessment using biotic indices started in the permanent streams (e.g., Cortes et al, 1986;Cortes & Monzon, 1991). Due to methodological difficulties, only recently were these studies extended to temporary streams (Graça & Coimbra, 1998;Prenda & Gallardo-Mayenco, 1996;Coimbra et al, 1996;Rueda et al, 2002), defined as those that flow only seasonally (Boulton & Suter, 1986;Lake et al, 1986).…”

“…Flow conditions are normally associated with taxa more sensitive to organic contamination (Coimbra et al, 1996;Prenda & Gallardo-Mayenco, 1996;Prenda & Gallardo-Mayenco, 1999;Ubero-Pascal et al, 2000). In contrast, under lentic conditions, these taxa tend to decrease and tolerant taxa become dominant in the community (Coimbra et al, 1996).…”

“…It must be sufficiently robust to integrate this natural variability, in order to be applicable over any temporal period (not dependent on a single hydrological condition in time). Studies concerning the development of assessment methodologies of temporary streams, covering different hydrological conditions, are scarce (Zamora Muñoz et al, 1995;Coimbra et al, 1996;Graça & Coimbra, 1998) and multimetric approaches are quite absent (Pinto et al, 2004).…”

Integrated Assessment of Running Waters in Europe

The generalization of ecological results from temporary streams needs the study of those ecosystems across a broad scale of running waters, covering the geographical ecological constraints involved (e.g., precipitation, temperature and geology). For the particular situation of Mediterranean streams in Southern Europe, high changes in water level, with unpredicting flood events, represent an important factor determining the structure and function of Mediterranean streams. This variability, inducing accentuated changes in the macroinvertebrate community, tends to influence the assessment methodologies. A set of metrics commonly used in Europe to assess organic degradation (Shannon-Wiener index, evenness, richness, BBI, IBE, BMWP , ASPT , DSFI, EPT, number of Trichoptera families, percentage of Gasteropoda, Oligochaeta and Diptera) and a multimetric index (IM9) developed to assess organic degradation in southern siliceous Portuguese basins were tested to evaluate quality at two contrasting sites (one unimpaired and another impaired by an identified point source of pollution). The multimetric index (IM9) composed by: ASPT (average score per taxon); GOLD (one minus percentage of Gasteropoda, Oligochaeta and Diptera); and TRICF (number of Trichoptera families), was the most suitable assessment methodology. IM9 presented a quite stable temporal pattern from February in late winter until June in early summer, even under the effect of episodic floods. A stepwise regression showed that most of tested metrics were significantly related to environmental variables (soluble reactive phosphorous, dissolved inorganic nitrogen and dissolved oxygen). Only richness, IBE and BMWP were not significantly influenced by environmental variables. Future research must be done covering the complete gradient of organic degradation, including the extension of multimetric assessment methodologies to temporary streams located in other regions under different geological and climatic conditions.

“…Ces taxons appartiennent par exemple aux Chironomidae, Culicidae, Syrphidae (Coimbra et al, 1996). Une telle évolution des taxons est une indication sur la différence des caractéristiques des rivières et des stations qui peut s'expliquer non seulement par la différence d'habitats mais aussi par l'impact des rejets sur le milieu récepteur.…”

RESUMELa répartition géographique des espèces dans un écosystème est liée à leurs habitats. L'influence du substrat sur la distribution des macroinvertébrés benthiques de trois hydrosystèmes de la ville de Kinshasa (Gombe, Kinkusa et Mangengenge) était étudiée de mai en début septembre 2014. L'échantillonnage des macroinvertébrés était effectué grâce au filet troubleau dans chaque type de substrat. Douze types de substrats étaient regroupés en deux grandes catégories : la vase et le sable. Le gravier ayant été présent en faible proportion. Cinq mille huit cent quatre-vingt et un macroinvertébrés appartenant à trente deux familles ont été récoltés : seize familles ont été récoltés respectivement dans la Gombe et dans la Kinkusa; et vingt quatre dans la Mangengenge. Seize familles étaient localisées dans le sable et le gravier, quinze dans la vase et cinq étaient concomitamment présentes dans le sable et la vase. La présence des Trichoptères dans la Mangengenge associée aux valeurs indiciaires de Shannon et Weaver (3,6) et à la note de l'Indice Biologique Général Normalisé (IBGN) (14/20), montre que l'eau de cet hydrosystème est de bonne qualité par rapport à celles des rivières Gombe et Kinkusa qui sont polluées et similaires à 73%.

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.
