A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil Biota Neotropica
Souza,Natália Freitas de; Baptista,Darcílio Fernandes; Buss,Daniel Forsin.
Abstract: Biological assessments that use the reference condition approach are based on the concept of comparing a site's observed biology to sites where disturbance is minimal or absent. However, in many regions of the world, such areas are scarce or nonexistent. In this study, an alternative approach proposed by Chessman and Royal for bioassessment without reference areas based on environmental filters was tested in Brazil. This approach assumes that key environmental features act in the selection of potential colonists, from a regional pool of taxa, based on the ecological traits (tolerances) possessed by each taxon. We developed the approach by: 1) determining the regional pool, based on a large Atlantic Forest biome database; 2) selecting...

Analysis of the error associated with the subsampling of Chironomidae in an intermittent stream of semi-arid Brazil Biota Neotropica
Farias,Rafaela Lima de; Alencar,Thuanny Fernanda Braga; Lima,Jéssica Alcoforado de Sena; Medeiros,Elvio Sergio Figueredo.
Chironomidae is a common family in freshwaters, often occurring at high densities, which hinders the processing of large samples, given that time and labor are usually limited. The present study aims at evaluating the extent of the error related with the subsampling of Chironomidae from a larger sample with regard to the size of the individuals between a sample and the subsample. A total of 9195 chironomids were collected from three sites in an intermittent stream. Samples were taken using a D-shaped net (250 µm) on eight occasions. Individuals from each sample were homogenized in a gridded Petri dish and coordinates from lines and columns were randomly drawn. Individuals from the assigned coordinates were selected until 100 individuals or 10% of the...

Benthic macroinvertebrate community structure and seasonal variation in a neotropical stream in the State of Alagoas, Brazil Biota Neotropica
Linares,Marden Seabra; Faccioli,Gregorio Guirado; Freitas,Liriane Monte.
This paper presents a study on the macrobenthic community in the Salvia stream, a headwater stream that runs through a conserved Atlantic forest fragment in the state of Alagoas, Brazil, and identifies the environmental factors that most influence the community structure. Ten sampling sites were chosen, conducting each collection during the rainy season of 2010 and the dry season of 2011. At each site the macroinvertebrates were collected using a D net (0.250 mm mesh). Water samples were collected and taken to the laboratory to analyze Dissolved Oxygen, Conductivity, pH and Alkalinity. Water temperature, surface current speed and depth were measured at the site. Canonical Correspondence was used to analyze the effect of environmental factors on the...

Benthic macroinvertebrate community structure in a stream of the north-west region of Paraná State, Brazil Biota Neotropica
Bagatini,Yara Moretto; Delariva,Rosilene Luciana; Higuti,Janet.
This study aimed to survey the benthic macroinvertebrate fauna of a first order stream located in an agricultural area, and to assess the environmental factors involved in the spatial distribution of this community. Invertebrates were gathered in November 2007 at three sampling sites distributed along the Itiz Stream, located in Marialva municipality, Paraná State. At each site, we measured the physical and chemical variables of the water, and then took four samples, using Surber sampler. In order to evaluate the differences in density, richness, diversity and evenness, we employed an ANOVA and a DCA to summarize biotic data. The invertebrates were categorized into functional groups and the BMWP score was applied to calculate the biological integrity of...

Biomass estimation of Triplectides egleri Sattler (Trichoptera, Leptoceridae) in a stream at Ducke Reserve, Central Amazonia Rev. Bras. entomol.
Brito,Janaina Gomes de; Martins,Renato Tavares; Soares,Kleicy Maciel; Hamada,Neusa.
ABSTRACT Biomass is a fundamental measure for understanding the structure and functioning (e.g. fluxes of energy and nutrients in the food chain) of aquatic ecosystems. We aim to provide predictive models to estimate the biomass of Triplectides egleri Sattler, 1963, in a stream in Central Amazonia, based on body and case dimensions. We used body length, head-capsule width, interocular distance and case length and width to derive biomass estimations. Linear, exponential and power regression models were used to assess the relationship between biomass and body or case dimensions. All regression models used in the biomass estimation of T. egleri were significant. The best fit between biomass and body or case dimensions was obtained using the power model,...

Biting midges (Diptera: Ceratopogonidae) from an urban forest fragment in Central Amazon (Brazil): Effects of opening areas on abundance, richness, and composition Anais da ABC (AABC)
DOURADO,EDUARDA D.R.; FERREIRA-KEPPLER,RUTH L.; MARTINS,RENATO T.; RONDEROS,MARIA M..
ABSTRACT We assessed the immature stages of Ceratopogonidae (Diptera) in artificial containers in an urban forest fragment in Manaus (Brazil), including their behavioral, biological and ecological information. In addition, we evaluated the effects of deforestation in an open and forested area on Ceratopogonidae communities. Immatures were sampled between August 2012 and July 2014 in artificial containers installed in both habitat types. We collected 685 immatures of seven morpho-species of Bezzia Kieffer, Culicoides Latreille, Dasyhelea Kieffer, Forcipomyia Meigen, and Palpomyia Meigen. In the open area, we recorded higher temperature and electrical conductivity values than in the forested area; however, these variables did not differ between seasons....

Checklist of dragonflies and damselflies (Insecta: Odonata) of the Amazonas state, Brazil Biota Neotropica
Koroiva,Ricardo; Neiss,Ulisses Gaspar; Fleck,Günther; Hamada,Neusa.
Abstract: Here we provide a checklist of the odonates from Amazonas state, Brazil. We registered 324 species and 101 genera, making Amazonas the Brazilian state with the most Odonata species recorded. The families with the highest number of species were Coenagrionidae with 32 genera and 101 species, followed by Libellulidae with 28 genera and 100 species and Gomphidae with 12 genera and 45 species. Some regions of Amazonas state remain poorly explored, such as the southern area, and large municipalities, such as São Gabriel da Cachoeira. This work underlines the importance of the biological diversity from Amazonas state and the Amazonian Biome for Odonata species richness in Brazil and shows that many areas in the world’s largest tropical forest have not...

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)...

Chironomidae (Insecta, Diptera) associated with stones in a first-order Atlantic Forest stream RChHN
ROSA,BEATRIZ F. J. V; VASQUES,MONIQUE; ALVES,ROBERTO G.
Stones are stable substrates in streams, usually sheltering high richness and abundance of invertebrates. To investigate the structure of the Chironomidae assemblages associated with stones in a first-order stream located in an Atlantic Forest reserve in two periods of the year, stones with diameters from 10 cm to 25 cm were collected along a stretch of 100 m in riffle areas, during three months in the dry season and three months in the rainy season. The structure of the community was analyzed for each period through calculation of observed richness, Shannon's diversity (H'), and Pielou's evenness. The ordination of the samples from the dry and rainy seasons was evaluated by detrended correspondence analysis (DCA) and the presence of indicator species in...

Chironomidae (Insecta: Diptera) of different habitats and microhabitats of the Vacacaí-Mirim River microbasin, Southern Brazil Anais da ABC (AABC)
KÖNIG,RODRIGO; SANTOS,SANDRO.
The Chironomidae family is one of the main groups of aquatic insects present in streams. This work aimed to investigate the influences of anthropogenic pressures and substrate types on chironomid community composition and structure. Chironomid larvae were collected during the summer of 2007 at four sites along the Vacacaí-Mirim River microbasin, chosen based on the different available benthic substrates. The organisms were identified in the laboratory at the genus level, and the density, the rarefied taxonomic richness and the Shannon diversity index were calculated. The faunal structure was subjected to an ANOVA to compare the metrics among sites and substrates. The community composition of the sites was subjected to a multivariate statistical analysis....

Concordance between macroinvertebrate communities and the typological classification of white and clear-water streams in Western Brazilian Amazonia Biota Neotropica
Roque,Fabio de Oliveira; Lima,Diego Viana Melo; Siqueira,Tadeu; Vieira,Lisandro Juno Soares; Stefanes,Maurício; Trivinho-Strixino,Susana.
In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 taxa. Our results show that macroinvertebrate communities, at genus as well as family level, are in concordance to a priori classifications that distinguish between white and clear water streams. The main implication of our results for biomonitoring...
