Effects of environmental factors on community structure of Leptophlebiidae (Insecta, Ephemeroptera) in Cerrado streams, Brazil
Provedor de dados: 76
Autores: Brasil,Leandro S.; Shimano,Yulie; Batista,Joana Darc; Cabette,Helena S. R.
We analyzed the effects of environmental factors on abundance, species richness, and functional group richness of Leptophlebiidae in 16 sampling points along four Cerrado streams. Across three periods of 2005, we collected 5,492 larvae from 14 species in stream bed substrate. These species belong to three functional feeding groups: scrapers, filtering collectors and shredders. The abundance and species richness were not affected by water quality, but habitat quality related to presence of riparian vegetation had positive effects on the abundance of shredders. Our results add important information on the natural history of the species and functional groups of aquatic insects and also provide relevant data for the monitoring and conservation of streams in...

Provedor de dados: 76
Autores: Calor,Adolfo R.; Quinteiro,Fabio B.
ABSTRACT Trichoptera presents about 15,000 species described globally, of which 2,562 are recorded in the Neotropics and 642 in Brazil, distributed in 70 genera and 16 families. In Brazil, knowledge of the distribution and species richness of Trichoptera is incipient and heterogeneous, especially in some states such as Mato Grosso do Sul. In this work, we present an updated checklist of caddisflies for Mato Grosso do Sul state, representing nine families, 24 genera, and 16 species, four of them are new species records. Additionally, a new record of species for the Brazilian country is presented.

Benthic macroinvertebrate communities in sites with native forest presence and absence in north Patagonia
Provedor de dados: 76
Autores: Ríos-Escalante,Patricio De los; Esse,Carlos; Santander-Massa,Rodrigo; Saavedra,Pablo; Encina-Montoya,Francisco.
ABSTRACT The benthic fauna in northern Patagonian streams is characterized by presence of water quality indicator species. The aim of the present study was characterized the benthic communities in streams associated to sites with presence of Nothofagus forests and with human intervention without Nothofagus forests using null models in ecology, unified neutral theory of biodiversity (UNTB) and unweighted pair group method with arithmetic mean (UPGMA). The results of species co-occurrence null model revealed that species associations are random, whereas the results of niche overlap null models revealed the presence of niche overlap. The UNTB results revealed low species number. The results of UPGMA revealed that species composition is specific for each site...

Diversidade de presas e predadores (Insecta) em mesohabitats de córregos de Cerrado
Provedor de dados: 76
Autores: Giehl,Nubia F. S.; Resende,Bethânia O.; Roges,Paulo F. S. S.; Dias-Silva,Karina; Nogueira,Denis S.; Cabette,Helena S. R.
ABSTRACT Tropical streams feature high variety of habitats and environmental gradients, which reflect on the greater richness of aquatic insects. In this way, we evaluate if the diversity of aquatic insects of prey and predator categories is influenced by the type of substrates or by longitudinal portions in Cerrado streams. Our hypothesis is that prey and predator diversity will be determined by the type of substrate, assuming that the substrate serves as a source for foraging and / or refuge. In addition, the folhiço substrate will present greater abundance and richness due to the availability of shelter and food provided by this type of substrate. There will be differences in prey and predator composition among substrates, since some species have...

Autores: Ochiel, G.R.S.; Njoka, S.W.; Manyala, J.O.; Okeyo Owuor, J.B.
Using our own experimental data and published data, we review information on the control process of water hyacinth and its status in Lake Victoria basin, Kenya. Experimental results show that the mean fecundity of the two weevils is 290 and 237 eggs per female laid over a period of 16 weeks, with an adult longevity of 98 and 112 days for Neochetina bruchi and N. eichhorniae respectively. There was significant difference between the egg laying capacities of the two weevil species (p=0.002). The survival rate of the two species was significantly different (p&lt;0.05) for all life stages except for larvae to pupa. There was no significant interaction between the species and the method of experimental egg setting (p&lt;0.05). The fecundity of both N. bruchi...

Do container size and predator presence affect Culex (Diptera: Culicidae) oviposition preferences?
Provedor de dados: 92
Autores: dos Santos,José Junior; Kroth,Nádia; Breaux,Jennifer A.; Albeny-Simões,Daniel.
ABSTRACT Organisms with complex life cycles typically do not exhibit parental care. Hence, the ability of adult females to choose quality oviposition sites is critical for offspring success. Gravid females of many insect taxa have the capability to detect environmental conditions in water-holding containers (e.g., resource level, presence of competitors or predators) and to choose the sites that are most suitable for offspring growth and development. Mosquitoes may also detect physical container characteristics related to water permanence such as surface area, volume, or container size, and some species such as those in the genus Culex have been shown to prefer larger containers. However, predators may also preferentially colonize larger containers; thus,...

Biomass estimation of Triplectides egleri Sattler (Trichoptera, Leptoceridae) in a stream at Ducke Reserve, Central Amazonia
Provedor de dados: 92
Autores: 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,...

Provedor de dados: 103
Autores: Nessimian,Jorge Luiz; Dumas,Leandro Lourenço.
The larva and pupa of Leptonema tridens Mosely, 1933 are described and illustrated. Larvae of L. tridens can be distinguished from other described larvae of Leptonema Guérin, 1843 mainly by the rodlike setae of the labrum and the forecoxa lacking processes, bearing only a row of spiniform setae on its inner surface. The specimens were collected in different localities of the Mantiqueira mountain range, Itatiaia massif, states of Minas Gerais and Rio de Janeiro, southeastern Brazil. Larvae build typical hydropsychid shelters and are found in rapids, attached to rocky substrates. Gut content analysis revealed that larvae are omnivorous-filterers.

Estimation of dry mass of caddisflies Phylloicus elektoros (Trichoptera: Calamoceratidae) in a Central Amazon stream
Provedor de dados: 103
Autores: Martins,Renato T.; Melo,Adriano S.; Gonçalves Jr,José F.; Hamada,Neusa.
Aquatic invertebrate biomass estimations are often important in ecological and biological studies. Biomass may be determined by regression models between body and case dimensions and dry mass. Using linear, exponential and power regressions we analyzed the relationship between body and case dimensions and the biomass of Phylloicus elektoros Prather, 2003. Furthermore, we used cross-validation to evaluate the predictions of our models and of the models developed for Phylloicus sp. from southeastern Brazil. We measured four body dimensions (head capsule width, interocular distance, body and pronotum length) of 152 larvae and two case dimensions (width and length) of 45 cases. Case width provided better fit with biomass than case length in all model classes....

Explaining dissimilarities in macroinvertebrate assemblages among stream sites using environmental variables
Provedor de dados: 103
Autores: Melo,Adriano S.
The relationship between community structure and environmental factors usually varies according to ecosystem type, group of organisms, and spatial scale. In this study I assessed whether dissimilarities among assemblages of stream macroinvertebrates are related to differences in environmental variables. Data consisted of macroinvertebrate samples of 10 stream sites during the dry season. Seven environmental variables were assessed. The relationship among dissimilarities in assemblage structure and dissimilarities in environmental variables was assessed using the BioEnv approach. Conductivity and measures related to stream size were the most important variables. However, part of the correlation with conductivity was due to the high value observed in a...

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...

First records of four species of the genus Americabaetis (Ephemeroptera: Baetidae) for Argentina
Provedor de dados: 99
Autores: Bardavid,Sofía; Nieto,Carolina.
The family Baetidae is the most diverse family into the Order Ephemeroptera and it has an almost cosmopolitan distribution. The genus Americabaetis Kluge was described in 1992 and actually it has 19 known species with a clearly Neotropical distribution. Although this genus is very common in lotic aquatic systems, it has been poorly studied in Argentina. Herein, we report four species for this country originally described from Brazil, Paraguay and Uruguay: A. labiosus Lugo-Ortiz &amp;amp; McCafferty, A. longetron Lugo-Ortiz &amp;amp; McCafferty, A. mecistognathus Salles &amp;amp; Raimundi, A. titthion Lugo-Ortiz &amp;amp; McCafferty.

Ephemeroptera, Plecoptera and Trichoptera assemblages in two Atlantic Rainforest streams, Southeastern Brazil
Provedor de dados: 104
Autores: Crisci-Bispo,Vera L.; Bispo,Pitágoras C.; Froehlich,Claudio G.
Assemblages of Ephemeroptera, Plecoptera and Trichoptera (EPT) of rocky substrates were studied in two streams of the Intervales State Park. Monthly collections with a Surber sampler (10 random sampling units, 1m²) were carried out from September 1999 to September 2000 and quarterly from December 2000 to September 2001 in the Bocaina and Água Comprida Streams. The EPT fauna in the Bocaina Stream was more diversified and more abundant than in the Água Comprida Stream. The EPT fauna was quite different in the two streams both in composition as in functional aspects. The results of this study indicate that there was not a clear seasonal pattern in the temporal variation of density.

Provedor de dados: 104
Autores: Bispo,Pitágoras C.; Oliveira,Leandro G.
The diversity and structure of Ephemeroptera, Plecoptera and Trichoptera (EPT) assemblages in streams of Central Brazil (Serra dos Pireneus, Pirenópolis, State of Goiás) was investigated. Abundance data of EPT were obtained in Central-West Brazilian streams in order to evaluate the effect of spatial variability, including the effect of size of the stream and anthropic action, and seasonality (dry and rainy seasons) on faunal diversity and structure. The immatures were collected with circular sieves (0. 5 mm mesh) during one hour at five collection stations over 14 months. From a spatial point of view, the data showed that anthropic action determined the patterns of diversity whereas the size of streams (1st and 3rd-4th orders) determined the faunistic...

Ephemeroptera, Plecoptera and Trichoptera assemblages in litter in a mountain stream of the Atlantic Rainforest from Southeastern Brazil
Provedor de dados: 104
Autores: Crisci-Bispo,Vera L.; Bispo,Pitágoras C.; Froehlich,Claudio G.
The study of Ephemeroptera, Plecoptera and Trichoptera associated with litter in southeastern Brazil streams aimed to answer the following questions: 1) Does richness and composition of EPT fauna differ between riffle and pool mesohabitats despite being associated to the same substratum, litter? 2) Does the similarity of the EPT fauna between both mesohabitats change with time? 3) Does the EPT functional feeding structure differ between both mesohabitats (riffles-pools)? In order to answer these questions, monthly collections, from November 1999 to June 2000, were done in Ribeirão (Stream) Bocaina with a D-net (10 litter patches in riffles and 10 in pools). The EPT fauna at Ribeirão Bocaina was more diversified and more abundant in the litter in riffles...

Provedor de dados: 36
Autores: MARTINS,Renato Tavares; SOARES,Kleicy Maciel; HAMADA,Neusa.
ABSTRACT We reared field-collected egg masses of the caddisflies Phylloicus amazonas (n = 2) and Phylloicus elektoros (n = 7) to adulthood. First instar larvae of both species hatched up to five days after field collection. Median development time from first larval instar to adult was 229 days for P. amazonas and 275 for P. elektoros, including the pupal development time (median of 13.5 and 16 days, respectively). Shredder organisms have been used frequently in studies related to organic matter processing in freshwater ecosystems. The biological information reported in here may be useful for the design of experimental studies in the field or under laboratory conditions.

ABSTRACT Neotropical amphibians play important roles as preys and predators in freshwater and terrestrial ecosystems. The subfamily Pseudinae includes small and medium-sized frogs within three genera representing 13 valid species. Most published records of predation on Pseudinae frogs are anecdotic and scarce. Herein, we provide five new reports of predation and presenting a detailed literature review on Pseudinae predation, with 15 studies published between 1983-2017. Pseudinae species were preyed at both day and night by a wide variety of predators, principally birds. Adults were preyed upon more frequently than juveniles and tadpoles. In the present study, most predators were diurnal, with birds accounting for most records. A variety of invertebrates...

The aim of this study was to test the effect of agricultural and forestry land use on the structure of mayfly assemblages in low-order streams. Twenty-nine headwater streams were investigated in the state of São Paulo. We analyzed 15 streams in pristine areas (mixed tropical rainforest, semideciduous forest and dense tropical rainforest), and 14 streams covered with sugarcane, eucalyptus and pasture. Mayfly richness obtained by rarefaction curves was higher in pristine areas (21 genera), especially in mixed and semideciduous forest when compared to land use (9 genera), where values were particularly low in sugarcane plantation (3 genera). The non-metric multidimensional scaling (NMDS) ordination showed clear difference in mayfly assemblages between land...

Autores: 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....

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...

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...

A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil
Provedor de dados: 49
Autores: 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...

Checklist of dragonflies and damselflies (Insecta: Odonata) of the Amazonas state, Brazil
Provedor de dados: 49
Autores: 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...

Benthic macroinvertebrate community structure in a stream of the north-west region of Paraná State, Brazil
Provedor de dados: 49
Autores: 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...

Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil
Provedor de dados: 49
Autores: Braun,Bruna Marmitt; Salvarrey,Andrea Vanesa Batalla; Kotzian,Carla Bender; Spies,Marcia Regina; Pires,Mateus Marques.
The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages’ genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages’ distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The...

Relative size of gills of Cloeodes jaragua Salles &amp;amp; Lugo-Ortiz, 2003 (Ephemeroptera, Baetidae) on pool and riffle areas of streams at the Atlantic Rainforest
Provedor de dados: 49
Autores: Gonçalves,Inês Corrêa; Cid,Bruno; Mortati,Amanda Frederico; Quesado,Letícia Barbosa; Nessimian,Jorge Luiz.
Physical environment of streams present many challenging factors to the organisms living under its influence. Water speed, one of the most important factors affecting such environments, has local influence on substrata, temperature, and oxygen levels. It acts determining species distributions and morphological and behavioral adaptations of organisms. The aim of this study was to assess the relative size of gills of Cloeodes jaragua on two mesohabitats: lentic environment (river dam) and lotic environment (fast flowing area of a stream) in Parque Nacional da Serra dos Órgãos (RJ, Brazil). Twenty individuals were collected on each environment and width of the head and gills were taken. Lentic environment showed nymphs with broader and more constant...

First report of Simuliidae and Chironomidae (Diptera) living on nymphs of Lachlania Hagen (Ephemeroptera: Oligoneuriidae) in South America
Provedor de dados: 49
Autores: Pepinelli,Mateus; Siqueira,Tadeu; Salles,Frederico Falcão; Shimbori,Eduardo Mitio.
We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated with Lachlania nymphs. We believe that all of these associations can be classified as opportunistic (or casual) attachment.

Provedor de dados: 57
Autores: BAPTISTA,D. F.; BUSS,D. F.; DORVILLÉ,L. F. M.; NESSIMIAN,J. L.
Diversity and habitat preference of macroinvertebrates were studied in Macaé River basin, Rio de Janeiro State, Brazil, along its longitudinal gradient. We selected stream reaches corresponding to 1st, 2nd, 4th, 5th and 6th orders. A Surber sampler was used to collect four macroinvertebrates samples of each substrate (sand, litter in pool areas, stones, and litter in riffle areas) during the three sampling periods, defined based on the rain regime: April (end of the rainy season), July (dry season), and October (beginning of the rainy season). We identified 46,431 specimens corresponding to 117 taxa. Analysis of diversity numbers (both for family or genus level) indicated that all insect taxonomic orders had higher numbers on 2nd order stream reach, except...
