“…The same results were obtained by Czachorowski [1988] while studying caddisflies in the River Pasłęka, above and below a dam reservoir -Pierzchalskie Lake; however, the results obtained for H. angustipennis which was also found in this river are completely different -it was absent in Pasłęka below the dam. H. pellucidula, in comparison to H. contubernalis, needs higher current velocity and higher oxygen content [Becker 1987]; moreover, it is sensitive to phosphates and ammonium but tolerant to suspended solids [Bonada et al 2004] which also corresponded with the data on water quality of Regional Inspectorate of Environment Protection. At sites below the reservoir, especially 5 and 6, the influence of the city can worsen the habitat conditions of living organisms of the River Bystrzyca.…”

The aim of the paper was to investigate the impact of the eutrophic dam reservoir on the fauna of Trichoptera of the mediumsized River Bystrzyca in the area of the Lublin Upland. Material collected at three sites above and three sites below the reservoir was analyzed with respect to: species composition and diversity, dominance and trophic structures, essential physical and chemical parameters of water, both at the species as well as assemblage level. The obtained results indicated the unfavorable influence of the reservoir on Trichoptera which was expressed by the decrease in the number of species and diversity below the dam, the disturbances of dominance and trophic structures as well as the increase in the number of specimens of the species insensitive to pollution. The more detailed characteristic of the representatives of the family Hydropsychidae is also given -their distribution and preferences against habitat conditions in the arrangement: river-reservoir-river.

“…This suggests that it is not justified to use only the genera of Trichoptera as biological indicators. At the family level, Brachycentridae and Sericostomatidae are the most susceptible to pollution of all Trichoptera families (Bonada et al, 2004), and in the present study they were recorded only at the least polluted localities (3 and 7). The factors limiting the distribution of Hydropsychidae change with the changing constitution of the water and it is often not simple to distinguish between habitat quality or water quality as primary causes (Stuijfzand et al, 1999), which implicates that this family is not suitable as a biological indicator.…”

Key-words:caddisfly, river, community structure, environmental factors, river continuum concept Monthly samples of caddisfly (Trichoptera) larvae were taken from ten localities along a 151 km long section of the Nišava River (eastern Serbia) during a one year study, with the aim to assessing the spatial composition of the caddisfly assemblage along the river gradient, to identify key environmental factors influencing its variability, to find out if caddisflies are suitable as biological indicators of water quality in this region, and to asses if the caddisfly assemblage in the river follows the river continuum concept. Twenty-three morphologically distinct taxa belonging to 14 genera were identified. The dominant family was Hydropsychidae with 70.34% of specimens examined, followed by Brachycentridae with 9.74% specimens. The longitudinal variability of the caddisfly assemblage has shown a clear dependence on physical and chemical parameters. The CCA analysis suggests that BOD 5 and concentration of total phosphorus are the most important factors in structuring the caddisfly assemblage. The species diversity was greatest at localities with the highest oxygen concentration and low nutrient levels. The caddisfly assemblage proved to be useful in identifying differences in environmental conditions in the Central Balkan region. RÉSUMÉ L'influence des facteurs environnementaux sur la structure des communautés de phryganes (trichoptères) dans la rivière Nišava (péninsule centrale des Balkans) Mots-clés :phryganes, rivière, Des échantillons mensuels de larves de phryganes (trichoptères) ont été préle-vés dans dix localités réparties dans un secteur long de 151 km de la rivière Nišava (Serbie orientale) au cours d'une étude d'un an, dans le but ; d'évaluer la composition spatiale de l'assemblage de phryganes le long de la rivière, d'identifier les principaux facteurs environnementaux qui influent sur sa variabilité, pour savoir si les trichoptères sont appropriés comme indicateurs biologiques de la qualité de l'eau dans cette région, et d'évaluer si l'assemblage de phryganes dans la rivière suit le concept de continuum fluvial. Vingt-trois taxons morphologiquement distincts appartenant à 14 genres ont été identifiés. La famille dominante était les Hydropsychidae avec 70,34 % des spécimens examinés, suivis par les Brachycentridae avec 9,74 % des spécimens examinés. La variabilité longitudinale de l'assemblage de phryganes a montré une dépendance claire des paramètres physiques et chimiques. L'analyse CCA suggère que la DBO 5 et la concentration de phosphore total sont les facteurs les plus importants dans la structuration de l'assemblage de phryganes. La diversité des espèces était la plus élevée dans des localités ayant la plus forte concentration d'oxygène et de faibles niveaux d'éléments nutritifs. L'assemblage de phryganes s'est avéré utile pour identifier les différences dans les conditions de l'environnement dans la région centrale des Balkans.

“…In the present study, it was identified in the samples collected from 7 stations (Table IV, V). The two species of genus Hydropsyche (H. instabilis and H. fulvipes) are generally characteristic for the lotic eco-systems whose speed can vary from moderate to high, although their high tolerance to the water quality may suggest a large distribution (Admiraal et al, 2000;Bonada et al, 2004;Brunke, 2004). Establishing maximum percentage numerical abundance values for the same two aforementioned species shows, in case of quantitative sampling as well, low sensitivity and high adaptability of these species to habitat conditions (Lukáš and Krno, 2003;Kazanciand and Dügel, 2008).…”

“…With a distribution and a preference different for genus habitat, E. madida can frequently be found at altitudes between 1500 and 300 m in upper and lower trout region also (Graf et al, 2008;Paulsa et al, 2008;Schmeraa and Erös, 2011). In contrast, species of genus Rhyacophila were identified as having the lowest values, the 3 species being generally conditioned by physical and chemical parameters, particularly for waters with low temperature, high flow rate and a sub-layer made up mainly of gravels (Langheinrich et al, 2002;Bonada et al, 2004;Hildrew, 2009).…”

Key-words:caddisflies, biodiversity, Natura 2000, DPSIR, RomaniaThe implementation of some strategies such as DPSIR framework may lead to a better coordination at both local and national level with a view to maintaining biodiversity and quality of water bodies. The different sensibility of the benthic macroinvertebrates has been used in determining the manner in which these communities are being influenced by the socioeconomic development, in the end modifying the biodiversity. The present study aims at presenting a list concerning the different species of caddisflies identified in the larva phase in Natura 2000 site Lower Gorge of Mureş river, to draw attention on existing threats regarding the quality of aquatic ecosystems based on the indentified caddisflies species and also to propose a series of conservation measures considered essential to the sustainable development of socio-ecological complexes in the target area. The sample collecting points were represented by 13 stations used to identify the caddisflies species in the larva phase. There were identified 20 species included in a number of 7 families. The most frequent species were Hydropsyche instabilis and Hydropsyche fulvipes (qualitative samples), and Hydropsyche instabilis, Hydropsyche fulvipes and Ecclisopteryx madida (quantitative samples), respectively. RÉSUMÉLe rôle du cadre conceptuel DPSIR : une étude de cas concernant les menaces et les mesures de conservation pour les trichoptères en Roumanie Mots-clés :trichoptères, biodiversité, Natura 2000, DPSIR, RoumanieLa mise en oeuvre de certaines stratégies telles que le cadre DPSIR peut conduire à une meilleure coordination au niveau local et national en vue de préserver la biodiversité et la qualité des masses d'eau. La sensibilité variable des macroinvertébrés benthiques a été utilisée pour déterminer la manière dont ces communautés sont influencées par le développement socioéconomique, modifiant finalement la biodiversité. La présente étude vise à pré-senter une liste concernant les différentes espèces de trichoptères identifiés en phase larvaire dans le site Natura 2000 de la partie inférieure des gorges de la rivière Mures, pour attirer l'attention sur les menaces existantes concernant la qualité des écosystèmes aquatiques en fonction des espèces de trichoptères repérées et également de proposer une série de mesures de conservation considérées comme essentielles pour le développement durable des complexes socio-écologiques dans la zone cible.
