A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil Biota Neotropica
Gonçalves,Fábio Bertolini; Menezes,Márcia Santos de.
Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average...

Assessing the effects of urbanization on streams in Tierra del Fuego Ecología austral
Zagarola,Jean-Paul A; Martínez Pasteur,Guillermo; Lopez,María Eugenia; Anderson,Christopher B.
We set out to understand how urbanization affects streams in Ushuaia, Tierra del Fuego. Paired t-tests and linear regressions were used to compare physico-chemical stream habitat variables (i.e., temperature, turbidity, conductivity, dissolved oxygen and pH) and benthic macroinvertebrate community structure (i.e., density, taxonomic richness, Shannon-Weiner diversity) and function (functional feeding groups [FFG]) in four watersheds with urban and reference sites. We then calculated indices of biotic integrity for habitat (rapid visual assessment protocol [RVAP]) and benthos (Ephemeroptera, Plecoptera, Trichoptera richness [EPT], family biotic index [FBI], rapid bioassessment protocol [RBP] and biotic monitoring Patagonian streams [BMPS]). Results...

Assessing the performance of macroinvertebrate metrics in the Challhuaco-Ñireco System (Northern Patagonia, Argentina) Iheringia, Sér. Zool.
Mauad,Melina; Miserendino,M. Laura; Risso,Miguel A.; Massaferro,Julieta.
ABSTRACT Seven sites were examined in the Challhuaco-Ñireco system, located in the reserve of the Nahuel Huapi National Park, however part of the catchment is urbanized, being San Carlos de Bariloche (150,000 inhabitants) placed in the lower part of the basin. Physico-chemical variables were measured and benthic macroinvertebrates were collected during three consecutive years at seven sites from the headwater to the river outlet. Sites near the source of the river were characterised by Plecoptera, Ephemeroptera, Trichoptera and Diptera, whereas sites close to the river mouth were dominated by Diptera, Oligochaeta and Mollusca. Regarding functional feeding groups, collector-gatherers were dominant at all sites and this pattern was consistent among years....

Assessment of water quality in temperate-plain streams (Argentina, South America) using a multiple approach Ecología austral
Ocon,Carolina S.; Rodrigues Capítulo,Alberto.
We assessed the water quality in two pampean lotic systems (Argentina), the Juan Blanco and Buñirigo streams, subjected to different land uses (i.e., the UNESCO Biosphere Nature Reserve vs. industry and agriculture, respectively) through measurements of physicochemical data and the structural parameters of the macroinvertebrate assemblages in addition to ecotoxicological analyses. The objective was to identify the degree of ecological impairment in adversely affected areas and the consequent effects on the biota. The results obtained allowed the establishment of different water-quality classes within the study area. According to the indices applied, the downstream zone of the Buñirigo stream was categorized as moderately polluted on the basis of losses of...

Chironomidae from Eastern Amazon: understanding the differences of land-use on functional feeding groups. Repositório Alice
SONODA, K. C.; MONTELES, J. S.; FERREIRA, A.; GERHARD, P..
Abstract: Deforestation for agricultural purposes is the most dangerous human action against the conservation of the Brazilian Amazon Forest; its rates reached almost 20% of the original forested area. Many studies have been conducted on Chironomidae systematics and ecology over the Amazon biome, but most concerned the Central Amazon, while little is known about Chironomidae diversity and the effects of land development and agriculture intensification on the aquatic biota from Eastern Brazilian Amazon. The present study analyzed the effects of different land-use and land-cover on Chironomidae assemblages. Land-Use and Land-Cover (LULC) at the riparian zone were assessed from satellite imagery and three categories were defined: Forest, Secondary (Capoeira)...

Conservation of mayflies (Insecta, Ephemeroptera) in Espírito Santo, southeastern Brazil Rev. Bras. entomol.
Massariol,Fabiana Criste; Soares,Elaine Della Giustina; Salles,Frederico Falcão.
Conservation of mayflies (Insecta, Ephemeroptera) in Espírito Santo, southeastern Brazil. Ephemeroptera exhibits great diversity among bodies of freshwater in the Atlantic Forest, a biome that is suffering from massive human impact. Within this context, the creation of conservation units using biological information is more recommended than economic, cultural, or political criteria. The distribution pattern of 76 Ephemeroptera species was analyzed using the biogeographical methods Parsimony Analysis of Endemicity and Network Analysis Method in order to infer relevant areas for conservation of the mayfly community in Espírito Santo. The results obtained from both analyses were largely congruent, and pointed out four relevant areas for conservation: two in...

Diet of invertebrates sampled in leaf-bags incubated in a tropical headwater stream Rev. Bras. Zool.
Carvalho,Emerson M. de; Uieda,Virgínia S..
The diet of macroinvertebrates sampled in leaf-bags incubated in a tropical stream was analyzed on a spatial scale (one forested and one deforested area) and on a temporal scale (dry and rainy seasons). The macroinvertebrates were mostly represented by detritivores specialized in fine detritus (69%), followed by generalist detritivores (10% with a diet based on fine and coarse detritus), carnivores (10%), omnivores (8%), and one detritivore genera specialized on coarse detritus (3%). The detritivores exhibited a broad spatial and temporal distribution and were represented mainly by Ephemeroptera, Trichoptera and Diptera. Phylloicus sp. (Trichoptera) consumed mostly coarse detritus (CPOM) and can be classified as the unique specialist shredder in this...

Diet of Poecilia reticulata Peters, 1959 in streams from Paraná River basin: influence of the urbanization Biological Sciences
Alves, Gustavo Henrique Zaia; Tófoli, Raffael Marcos; Ganassin, Maria Julia Mileo; Hahn, Norma Segatti.
 This study aimed to assess the diet of Poecilia reticulata in rural (RS) and urban stream (US) and under seasonal influence. We hypothesized that rainfall have a strong negative impact on the diet of the species in the US, due to its abrupt effect on food resources; in RS this effect is less apparent. Both streams belong to Pirapó River sub-basin, Paraná River basin. Fishes were sampled bimonthly, between July 2007 and June 2008 in three sample sites along the longitudinal gradient of the streams, using electrofishing. According to the Feeding Index, in both streams the population consumed almost exclusively detritus associated with aquatic organisms (>95%), regardless of the hydrological period. The main taxa explored by fish were Simuliidae in RS and...

Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition Iheringia, Sér. Zool.
Saulino,Hugo H. L.; Trivinho-Strixino,Susana.
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ginger monotypic bank, forest partially invaded, native macrophyte monotypic bank and riparian forest. At each vegetal bank, we measured abiotic variables such as dissolved oxygen, pH, water temperature and depth. We analyzed the aquatic insects through abundance, richness and Simpson diversity. We used the non-Metric Multidimensional Scaling (nMDS) analysis to analyze the spatial distribution of each...

Impact of rainbow trout on aquatic invertebrate communities in subtropical mountain streams of northwest Argentina Ecología austral
Molineri,Carlos.
The present study was conducted to assess the effect of rainbow trout introduction on benthic invertebrate communities, stratified as epibenthos and infauna. Two main questions are explored: 1) do the trout-invaded streams show a different community structure than the streams with autochthonous fish?, and 2) does the presence of trout affect differentially the epibenthos and the infauna? Epibenthic and infaunal samples, drift samples and fish stomach content were sampled four times from three stations to assess the impact of rainbow trout (Oncorhynchus mykiss) on the invertebrate aquatic fauna. Only one species of native fish was recorded in the studied sites, the siluriform Trichomycterus corduvense. Both fish species were found always in allopatry. The...

Intra- and inter-annual variations in Chironomidae (Insecta: Diptera) communities in subtropical streams Rev. Bras. Zool.
Nava,Diane; Restello,Rozane M.; Hepp,Luiz U..
The structure and composition of stream benthic communities are strongly influenced by spatial and temporal factors. This study evaluated the intra and inter-annual variations in Chironomidae communities in subtropical streams. The organisms were sampled from 10 small-order streams during the summer and winter of 2010-2012. The number of chironomid specimens sampled was 7,568, distributed in 49 genera. Chironomid abundance and richness varied intra and inter-annually and community composition varied intra-annually (2010 and 2011). Water temperature, total organic carbon, nitrogen, and rainfall were correlated with chironomid community composition. The intra-annual variation of the community was dependent on climatic variations (temperature and rainfall)...

Leaf litter decomposition from native and non-native species in a freshwater forested wetland of Chile Gayana
Gómez-Capponi,Francisco; Correa-Araneda,Francisco; Díaz,Ma Elisa; Olguín,Manuel; Encina-Montoya,Francisco; Figueroa,Ricardo.
ABSTRACT Decomposition of leaf litter is a fundamental process for the functioning of forested wetlands. The rapid increment of forest plantations has involved a greater contribution of leaf litter of exotic origin to these ecosystems. The decomposition rate between leaf litter of native and exotic origin in a forested wetland of the Mediterranean zone of Chile was compared, as well as the contribution of bacteria and macroinvertebrate to this process. It was determined that the decomposition rate of the leaf litter presented significant differences (p < 0.05) between species, being faster in those of non-native origin. This could be due to differences in ecophysiological aspects of the leaves like the presence of chemical compounds such as waxes or...

LEAF LITTER MASS LOSS RATES AND ASSOCIATED FAUNA OF TREE SPECIES COMMONLY USED IN NEOTROPICAL RIPARIAN REFORESTATION Acta biol.Colomb.
BLANCO,JUAN F.; GUTIÉRREZ-ISAZA,NATALY.
A signature of globalization is the prevalence of exotic trees along reforested urban and rural riparian zones in the Neotropics, but little is known about the instream processing of its leaf litter. In this study, leaf litter breakdown rates were measured during 35 days using mesh bags within a reference headwater stream for seven exotic and three native tree species commonly used in urban and rural reforestation. Artocarpus altilis, Schefflera actinophylla and Terminalia catappa scored the highest mass loss rates (>85 %; mean life: t50.

Multimetric index for assessing ecological condition of running waters in the upper reaches of the Piabanha-Paquequer-Preto Basin, Rio de Janeiro, Brazil Rev. Bras. Zool.
Baptista,Darcilio F.; Souza,Roberta S. G. de; Vieira,Carla A.; Mugnai,Riccardo; Souza,Ana S.; Oliveira,Renata Bley S. de.
The objective of this study was to develop a rapid multimetric index using benthic macrofauna as bioindicators of ecological conditions for the upper reaches of the Piabanha-Paquequer-Preto Basin located in the state of Rio de Janeiro, Brazil. A total of 33698 macroinvertebrates were collected in 27 sites. Benthic macroinvertebrates were sampled using the multi-habitat method that consists in sampling 20 m² of substrate collected in approximate proportion to the representation of all major habitat types in the reach. A subsampling procedure was used. The main steps followed to develop and test the index were: exclusion of unsuitable metrics using box-whisker plots, considering the degree of overlapping among interquartile limits (1º-3º) and confirmed by...

PECES Y MACROINVERTEBRADOS MÓVILES DE HÁBITATS ARTIFICIALES EN LA BAHÍA DE TAGANGA, CARIBE COLOMBIANO Boletín de Investigaciones
Delgadillo-Garzón,Óscar.
Fishes and macroinvertebrates associated to two types of artificial habitats deployed in Taganga Bay were assessed by stationary visual census to compare these assemblages. Forty-one species of fishes and nine macroinvertebrates were observed in eleven visual censuses. The distribution patterns depicted in abundance and richness between the two types of habitats used (concrete blocks vs. artificial shelters), were a possible response to dissimilarities in their location and number of visual census. A relative high fish richness and diversity were found in these artificial habitats, in comparison to other artificial structures in Colombia, probably owing to their proximity with heterogeneous natural habitats. The use of complex artificial habitats could...
