“…Changes in chemistry of Lake Dołgie Wielkie led to the occurrence of macrophyte species previously not reported in the lake such as M. spicatum, C. submersum and C. demersum. The appearance of these species, indicated as typical of eutrophic waters, is probably due to the increases of the water trophic state triggered by the Great Cormorant colony (Arts, 2002;Szoszkiewicz et al, 2006).…”

“…Submerged macrophytes and epilithic diatoms appear to be very sensitive to the sedimentation of suspended solids (Descy & Coste, 1991;Kelly & Whitton, 1995;Kelly, 1998;Prygiel & Coste, 2000;Wetzel, 2001;Cirujano & Medina, 2002;Schneider & Melzer, 2003;Gosselain & al., 2005;Suárez & al., 2005;Moreno & al., 2006;Szoszkiewicz & al., 2006). Furthermore, some epilithic diatoms (Cymbella affinis, Diploneis parma, Fragilaria ulna, Gomphonema angustatum, Navicula similis, Nitzschia dissipata) and submerged macrophytes (Apium nodiflorum, Groenlandia densa) were either absent or less abundant at S-3 and S-4 with regard to S-1 (Tables 2 and 3).…”

“…Furthermore, some epilithic diatoms (Cymbella affinis, Diploneis parma, Fragilaria ulna, Gomphonema angustatum, Navicula similis, Nitzschia dissipata) and submerged macrophytes (Apium nodiflorum, Groenlandia densa) were either absent or less abundant at S-3 and S-4 with regard to S-1 (Tables 2 and 3). These diatoms and macrophytes usually grow better in unpolluted rivers and streams with naturally mesotrophic waters (Prygiel & Coste, 2000;Cirujano & Medina, 2002;Schneider & Melzer, 2003;Gosselain & al., 2005;Leira & Sabater, 2005;Szoszkiewicz & al., 2006). Conversely, other epilithic diatoms (Achnanthes lanceolata, Achnanthes minutissima, Amphora commutata, Amphora ovalis, Navicula capitatoradiata, Ecological responses of epilithic diatoms in a spanish river Navicula minima, Navicula recens, Navicula tripunctata, Nitzschia fonticola, Nitzschia sociabilis, Stauroneis anceps) and aquatic macrophytes (Cladophora sp., Phragmites australis, Ranunculus peltatus, Typha latifolia, Veronica anagallis-aquatica) clearly increased their abundances at S-3 and S-4 with regard to S-1 (Tables 2 and 3).…”

These diatoms and macrophytes are relatively tolerant of organic pollution and nutrient enrichment, growing well in eutrophic waters and often forming dense stands (Prygiel & Coste, 2000;Cirujano & Medina, 2002;Schneider & Melzer, 2003;Gosselain & al., 2005;Leira & Sabater, 2005;Szoszkiewicz & al., 2006). However, because aquatic mosses are in general considered to be indicators of good water quality (Suárez & al., 2005;Moreno & al., 2006), it is surprising that Leptodictyum riparium also increased its abundance at S-3 and S-4 with regard to S-1 (Table 2).…”

“…Nevertheless, many human activities are polluting freshwater ecosystems, modifying the structure of aquatic communities and thereby disrupting the functional continuum of river systems (Camargo & al., 2005). Indeed, anthropogenic pollution of freshwater ecosystems by the addition of organic matter and nutrients is an increasing phenomenon that affects many rivers worldwide (Camargo & al., 2006;Szoszkiewicz & al., 2006).…”

We examined the ecological responses of epilithic diatoms and aquatic macrophytes to organic pollution and nutrient enrichment caused by a trout farm effluent in the upper Tajuña River (Guadalajara, Spain). Four sampling sites were selected over the study area: one site (S-1) placed upstream from the trout farm was used as a reference station; sampling sites S-2, S-3 and S-4 were set, respectively, about 10, 100 and 1000 metres downriver of the trout farm outlet. The river bottom was mainly stony with cobbles and pebbles at S-1, S-3 and S-4, but at S-2 it was covered by a thick layer of organic sediment. Although some macrophyte species (Apium nodiflorum, Groenlandia densa) were either absent or fewer downstream of the farm, abundance (% coverage) and diversity (number of species) for the aquatic macrophyte community as a whole increased. In contrast, epilithic diatoms were completely absent at S-2, and some species (Diploneis parma, Fragilaria ulna, Gomphonema angustatum, Nitzschia dissipata) were also absent at S-3 and S-4. Indeed, diatom diversity (number of species) was lower at S-3 and S-4 than at S-1. However, diatom abundance (cells/cm 2 ) was higher at S-3 and S-4 than at S-1. Biological indices for diatoms (IBD, TDI) indicated a better water quality at S-1 than at S-3 and S-4, with a clear tendency to improve with distance from the fish farm. In contrast, biological indices of macrophytes (IM, IVAM-G) indicated a similar water quality at S-1, S-3 and S-4, but with bad water quality at S-2. We conclude that epilithic diatoms may be more useful than aquatic macrophytes for biological monitoring of fish farm pollution in fluvial ecosystems. However, as historical and seasonal factors may be relevant to understanding the distribution, abundance and diversity of primary producers in running waters, further studies on long-term seasonal changes are needed to improve the use of macrophyte and diatom indices in assessing fish farm pollution. En este trabajo examinamos las respuestas ecológicas de las diatomeas epilíticas y los macrófitos acuáticos a la contaminación orgánica y por nutrientes producida por el vertido de una piscifactoría situada en el tramo alto del río Tajuña (Guadalajara, España). Se seleccionaron cuatro puntos de muestreo a lo largo del área de estudio: uno aguas arriba de la piscifactoría empleado como punto control (S-1); los puntos S-2, S-3 y S-4 se ubicaron a 10, 100 y 1000 m aguas abajo del punto de vertido, respectivamente. El lecho del río era principalmente rocoso, con guijarros y cantos rodados en S-1, S-3 y S-4, pero en S-2 estaba cubierto por una gruesa capa de sedimento orgánico. Pese a que algunas especies de macrófitos (Apium nodiflorum, Groenlandia densa) resultaron ausentes o vieron reducidas sus abundancias aguas abajo del vertido, la abundancia (% covertura) y la diversidad (núme-ro de especies) del total de la comunidad de macrófitos acuáticos aumentó. En oposición a esto, las diatomeas epilíticas desaparecieron completamente en S-2, y algunas especies (Diploneis parma, Fr...

Streams with Ranunculion fluitantis and Callitricho‐Batrachion vegetation – or habitat type 3260 according to the European Habitats Directive – require particular conservation at biogeographic level but Member States carry individual responsibility. Within this framework, the environmental requirements of this habitat type in lower Belgium (Flanders) were analysed.Overall, current vegetation composition was not significantly related to adjacent land‐use but correlated mainly with physical–chemical conditions and to a lesser extent with distance to source and channel width. Even though sites with habitat 3260 generally showed lower levels of human impact, their abiotic features overlapped considerably with those of sites without habitat 3260 but still showing hydrophyte development.Thresholds occurred in the distribution of responsive macrophyte taxa, including the more common characteristic species of the habitat type, along gradients of increasing solutes and nutrients. Comparison with water quality standards proposed so far to support good ecological status for the European Water Framework Directive in lowland rivers suggests that compliance would probably allow this habitat to persist in most cases, although some discrepancies occur. This implies that more stringent objectives may be required in some water bodies.The present analysis focuses on the conditions delimiting occurrence of HT 3260, and therefore its range and area in lower Belgium. A comprehensive understanding of its favourable conservation status remains difficult in lowland regions where most rivers are subject to strong human impact and will require a more long‐term perspective that also considers management regime, physical habitat structure and connectivity.
