“…In many stream habitats, Chironomidae can be abundant on clumps of aquatic fountain mosses, Fontinalis spp. (Linhart et al 2002;Vlčková et al 2002;Bogut et al 2009). Aquatic bryophytes can interact with aquatic arthropods by providing them with space and shelter from predators (Stream Bryophyte Group 1999).…”

The non-biting midges, Chironomidae (Diptera), are dominant components of most freshwater ecosystems. Many chironomids construct tubes or cases as larvae out of various materials bound together with silk. The structures of tubes show a wide range of variation, and some are morphologically comparable to those of caddisflies. Herein a new species is described, Eukiefferiella endobryoniasp. nov., which exhibits a very unusual behavior in which it constructs tubes from aquatic mosses. This species’ fourth-instar larvae construct their cases exclusively from the leaves of Fontinalis mosses (Hypnales: Fontinalaceae) and exhibit a stereotyped behavior in which they remain attached to the apical shoot of the moss stem. The larvae then pupate within the case. The case of E. endobryoniasp. nov. represents one of only a few examples of chironomid tubes made exclusively out of plants. Based on the species delimitation analyses using the partial COI sequences, together with some morphological and behavioral characteristics, this species is hypothesized to be a member of devonica group, and especially may have a close affinity to E. dittmari (Lehman). A provisional typology for the diversity of chironomid tube structures is provided, with a summary of different tube structures, which can be used for future research.

“…Some authors found that Hydra prefer smaller size prey, such as the representatives of Bosmina genus (Dodds and Cole, 2007) or Cyclops (Cuker and Mozley, 1981). Hydra species are classified as valuable study organisms, especially as predatory invertebrates in trophic relations, studied also in matter and energy transport through various macrophyte species in the lake ecosystem which support a diverse composition and abundance of invertebrate fauna, depending on the morphology of leaves, production of allelopathic compounds and depending on whether they are submerged, floating or emerged plants (Cheruvelil et al, 2002;Mc Abendroth, 2005;Bogut et al, 2009). Representatives of Hydra genus appear in periphytic communities in Gornjogradsko Lake as in other shallow water bodies (Deserti et.…”

Phytophilous community on Myriophyllum spicatum was studied in a small artificial urban lake in the city of Osijek (eastern Croatia), during the spring and summer season in 2010. In the eutrophic conditions, macrophyte stands were well developed and in the formed periphyton representatives of the following invertebrate taxa were found: Hydrozoa, Nematoda, Gastropoda, Cladocera, Copepoda, Insecta larvae - including families Chironomidae and Coleoptera. They displayed differences in temporal abundance patterns. Two separate phases in macrophyte colonization with differences in invertebrate composition and abundance were recorded. Insect larvae, particularly Chironomidae, were most abundant in the first phase, through the spring period, and Hydra oligactis (brown hydra) was most abundant in the second phase, i.e. summer period. Concurrently, microcrustacean abundance declined towards the end of the summer. Results of the analyses indicated that water temperature and perihyton biomass were the variables exerting the main influence on the invertebrate assemblage, while interestingly, macrophyte size and biomass were negatively correlated with most of the fauna abundance. On the other hand, brown hydra was negatively correlated with all other invertebrate taxa, except gastropods. Larger surface of submersed macrophytes is the main parameter supporting the increase of invertebrate abundance due to providing protection from predators and growth for periphyton, an important food source for these phytophilous organisms. Macrophyte length was positively correlated with Hydra abundance, while Chironomids were more influenced by periphyton biomass. These organisms can indicate water quality conditions and a potential increase in primary and secondary production.

“…The presence of some phytoplankton species was related with organic matter and total nitrogen of plants, or directly correlated with macrophytes. Since Bogut et al (2009) found a significantly higher number of organisms associated with macrophytes than in water or sediment samples, the authors concluded that variations in macrophyte communities influenced both composition and abundance of communities of associated. Mulderij et al (2005) reported that macrophytes may affect phytoplankton populations differentially, and that low concentrations of phosphorus in the environment may impede the development of macrophytes and allowing the dominance of epiphytic algae.…”

Plankton communities and macrofauna associated to aquatic macrophyte stands in a shallow water-supply reservoir (21°14'09"S; 48°18'38"W) on an aquaculture farm were compared to evaluate the relationship between organism densities and some abiotic features of the reservoir. Water and communities associated were sampled at two sites, one in an area with the predominance of Eichhornia azurea (Sw.) Kunth and the other with the predominance of Salvinia auriculata Aublet. Communities associated with macrophytes were sampled with floating quadrants (0.5 m 2 ); the macrophytes were washed and plankton and macrofauna were fixated with 4% formalin and 1% lugol iodine; the specimens were then identified and counted. Plankton and macrofauna communities associated with S. auriculata and E. azurea had a similar diversity of species but different (p<0.05) in the abundance of associated organisms. Eichhornia azurea had the highest contents in dry and wet weight, total phosphorus, total nitrogen and organic matter. Planktonic algae were directly correlated with biomass of E. azurea. The taxa with highest densities were Rotifera and Zygnematophyceae. Results showed that the environmental variables associated with macrophytes presence in the shallow reservoir is a strong predictor of favourable conditions to maintain great diversity plankton community and macrofauna associated with plants. The role of macrophytes is important for not only stabilising the clear-water state and maintaining high diversity of organisms associated, but also it seems to be a good alternative to maintaining desirable water-supply quality for aquaculture farms.Keywords: floating macrophytes, plankton, aquaculture, water-supply, macrofauna.Qualidade da água e comunidades associadas com macrófitas em um reservatório de abastecimento de água para uma fazenda de aquicultura ResumoEste estudo objetivou comparar a composição da comunidade planctônica e a macrofauna associada aos bancos de macrófitas aquáticas em um reservatório (21º14'09"S e 48º18'38"O) de abastecimento de água para um sistema de aquicultura, avaliando a relação entre a densidade dos organismos e alguns fatores abióticos da coluna d'água. As amostras de água e comunidades associadas foram coletadas em dois locais, um em área dominada por Eichhornia azurea (Sw.) Kunth e outro em área dominada por Salvinia auriculata Aublet. As comunidades associadas com as macrófitas foram amostradas utilizando o método do quadrante (0,5 m 2 ), posteriormente lavadas e fixadas com formalina a 4% e lugol a 1%; depois os indivíduos foram identificados e contados. A comunidade planctônica e macrofauna associadas à S. auriculata e E. azurea apresentaram similar diversidade de espécies e, diferiram (p<0,05) em abundância em relação aos organismos associados. Massa seca e fresca, matéria orgânica, fósforo total e nitrogênio total foram mais elevados no tecido vegetal de E. azurea do que em S. auriculata. As algas planctônicas foram correlacionadas diretamente com a biomassa de E. azurea. Os grupos que apresent...
