“…Consequently, the Aeolosomatidae and Naididae reported in the present study can be counted as members of the aufwuchs community. As in the littoral zone of Lake Belau, those aufwuchs communities of oligochaetes and aphanoneurans which have been studied in detail were often dominated by a small number (2-5) of mostly naidid species (Botts & Cowell, 1993;McElhone, 1978;Schinborn, 1987), with the genera Chaetogaster, Nais and Stylaria often predominating (McElhone, 1978;Meuche, 1939;Miiller-Liebenau, 1956;Schonborn, 1987).…”

“…In this community, algae, invertebrate grazers, and predators are the most prominent components of the food web, with the Naididae being one of the numerically most important (e.g. Beckett et al, 1992;Botts & Cowell, 1993;Cattaneo, 1983), yet often neglected (Beckett et al, 1992), grazer groups. Aufwuchs biota are known to exhibit strong seasonal fluctuations, both in subtropical (Botts & Cowell, 1993) and temperate (e.g.…”

The Oligochaeta and Aphanoneura in the aufwuchs on Phragmites australis in a eutrophic hardwater lake were studied at two sites over a period of one year, in order to elucidate the structure and dynamics of this assemblage. The naidids Chaetogaster diastrophus, Nais spp., and Stylaria lacustris dominated the assemblage at any season. At both sites these taxa showed the same distinct pattern of successive population maxima in spring and summer: Chaetogaster diastrophus reached its peak density first, followed by Nais species, and eventually by Stylaria lacustris. Differences in temporal dynamics between sites were small apart from a second Stylaria maximum which was only observed at one site. Total naidid densities reached peak values of 3.8 individuals per cm 2 reed stem surface area. With mean individual biomass of 2.2 pg dry mass for Chaetogaster diastrophus, 13.3 ug for Nais, and 86 g for Stylaria lacustris, respectively, maximum total naidid biomass on reed stems was 44 pg dry mass per cm 2 . The biomass peak occurred later than that of total naidid density because in summer larger naidids dominated the assemblage. The observed succession appears to be consistent with seasonal changes in periphytic algal communities on the reed stems.

“…Oligochaetes, especially naidids, may prefer living on the surfaces of submersed macrophytes in lake ecosystems (Liihlein 1996, van den Berg et al 1997. Macrophytes seem to play a significant role in controlling the distribution and structure of oligochaete assemblages (Botts andCowell 1993, Healy andWalters 1994). Many studies have found that species richness, density, and composition of oligochaetes associated with macrophytes typically vary with the species, cover, and abundance of macrophytes (Bowker et al 1983, Beckett et al 1992, McElhone 1980, L6hlein 1996.…”

The assemblage of oligochaetes in the Liangzi Lake District, located in middle reaches of the Changjiang River, was studied from May to August, 2001. To establish species composition, richness, and abundance and detect the influence of environmental variables on oligochaete distributional patterns, 45 localities were sampled. All total, 20 species belonging to the families Naididae (eight species), Tubificidae (1 1 species), and Lumbriculidae (one species) were found. Branchiura sowerbyi, Tubifex sp. 1, and Aulodrilus pluriseta were the dominant species and contributed nearly 70% of the total abundance. The 45 sampling sites were separated into three groups based on composition and relative abundance of benthic oligochaete communities using two-way indictor species analysis associated with detrended correspondence analysis. Canonical correspondence analysis indicated that two plant variables (total plant cover and total submersed macrophyte biomass) were strongly correlated with the faunal gradient (p<0.05). Other predicator variables were water depth and total nitrogen.

“…In shallow lakes, these taxa also act like metabolism ecosystem's facilitator because they participate in nutrient cycling, reducing the organic particles sizes, which improves the decomposition process to the microorganisms (Vannote et al 1980, Keast 1985, Mcqueen et al 1986, Berg et al 1997, Silva et al 2009). These taxa's occurrence in sediment and marginal/riverine vegetation (Botts & Cowell 1993, Kurashov 1996 favors an extensive analysis from the ecosystem conditions because of the different patterns displayed by the community in response to the physical and chemical parameters, making it possible to understand how the ecosystem alterations influence the attributes richness, composition and density (Goulart & Callisto 2003, Bonada et al 2006.…”

The invertebrate's community in adjacent Alto Iguaçu's anthropic lakes of different environmental factors. Biota Neotrop. 13(1): http://www.biotaneotropica.org.br/v12n4/en/abstract?article+bn00813012013Abstract: Environmental differences occur between lentic and lotic communities' establishment, especially because of water time residence. Here we used a combination of field measurements and statistical analysis to evaluate the influent factors on the aquatic macroinvertebrates' composition and structure in 15 anthropogenic lakes from Alto Iguaçu's region. Macroinvertebrates were sampled from the marginal vegetation (with or without macrophytes) and sediment. Chemical parameters ranged among the anthropogenic lakes, mainly those which are connected to the Iguaçu River, beyond the presence or absence of macrophytes, interfering on the community's structure. Lake's morphometric data were measured in each lake and its relation to community was tested. The community structure was not related to the margin development index (Ds), macrophytes and altitude. Higher equitability was associated to the macrophytes presence in more than 30% of water surface and also where the riparian vegetation was more complex. Chironomids and oligochaetes densities were associated to lakes with the water surface completely covered by macrophytes and complex riparian vegetation. We observed a close association between productivity (phosphorous and nitrogen) and the community equitability (R = 0.3; p < 0.05) and Oligochaeta dominance (R = 0.32; p < 0.05), and not to Ostracoda's (R = 0.33; p > 0.05) and Chironomidae's (R = 0.34; p > 0.05) dominances, although we had not weighty difference among analyzed biological indexes. Resumo: Diferenças ambientais ocorrem entre o estabelecimento de comunidades de ambientes lênticos e lóticos, especialmente por causa do tempo de residência da água. Foi usada uma combinação de métricas de campo e análise estatística para avaliar os fatores influentes sobre a composição e estrutura de macroinvertebrados aquáticos em 15 lagos antropogênicos da região do Alto Iguaçu. Os macroinvertebrados foram amostrados da vegetação marginal (com ou sem macrófitas) e sedimento. Parâmetros químicos variaram entre os lagos antrópicos, principalmente aqueles conectados ao Rio Iguaçu, além da presença ou ausência das macrófitas, interferindo na estrutura da comunidade. Dados de morfometria de lagos foram mensurados e sua relação com a comunidade foi testada. A estrutura da comunidade não foi relacionada ao índice de desenvolvimento da margem (Ds), macrófitas e altitude. Maior equitabilidade foi associada à presença de macrófitas em mais de 30% da superfície da água e também onde a vegetação ripária foi mais complexa. Densidades de quironomídeos e oligoquetas foram associadas a lagos com a superfície completamente coberta por macrófitas e complexa vegetação ripária. Foi observada associação entre a produtividade (fósforo e nitrogênio) e a equitabilidade da comunidade (R = 0.3; p < 0.05) e dominância de Oligochaeta (R = 0.32; p ...
