The present paper aimed to evaluate the functional structural of the fish fauna in streams with different land uses in their micro basin. The fish fauna was sampled in fourteen streams, belonging to four watershed, between 2006 and 2014, by electric fishing technique. The streams were categorized according to land use and occupation and the species were classified according to their functional traits. Were sampled 81 fish species distributed in different functional groups related with the tolerance to hypoxia, food use (trophic guilds), reproduction (parental care) and habitat use. Bidimensional graphics were built with the data biomass of the functional groups, showing that the groups that stood out, independent of the land use, were the omnivorous, benthics, and nonguarders species. The Monte Carlo test proved there is dependence between the functional traits and land use. The functional diversity analyses showed that the functional metrics decreased substantially as it increases the land use and occupation, mainly in urban streams. It follows that the land use exerts direct influence on functional diversity of fish species in streams.
O presente trabalho objetivou avaliar a estrutura funcional da fauna de peixes de riachos em riachos com diferentes usos do solo em suas microbacias. A fauna de peixes foi amostrada em 14 riachos, pertencentes a quatro bacias hidrográficas, entre 2006 e 2014, por meio da técnica de pesca elétrica. Os riachos foram categorizados de acordo com o uso e ocupação do solo e as espécies foram classificadas de acordo com suas características funcionais. Foram amostradas 81 espécies distribuídas em diferentes grupos funcionais relacionados à tolerância a hipóxia, uso do alimento (grupos tróficos), reprodução (cuidado parental) e uso do hábitat. Gráficos bidimensionais foram construídos com os dados de biomassa dos grupos funcionais, mostrando que os grupos que se destacaram, independente do uso do solo, foram os omnívoros, os bentônicos e não guardadores. O teste de Monte Carlo atestou que há dependência entre as características funcionais e o uso do solo. A análise de diversidade funcional (DF) mostrou que as métricas funcionais diminuíram consideravelmente a medida que aumentou o uso e ocupação do solo, principalmente nos riachos urbanos. Conclui-se que o uso do solo exerce influência direta sobre a diversidade funcional das espécies de peixes em riachos

Texto completoThe present work tested the effects of frequency, intensity and disturbance area on the aquatic macroinvertebrate assemblages, in order to answer the following questions: 1) do the physical disturbances affect the abundance, richness and composition of macroinvertebrate assemblages? 2) Do the finding results confirm the intermediate-disturbance hypothesis (HPI) or dynamic-equilibrium model (MED) predictions? To answer these questions, experimental manipulation of substrate (frequency, intensity and size of disturbed area) were made and their effects on aquatic macroinvertebrate fauna in an Atlantic Forest stream (Southeast of Brazil) were evaluated. The abundance and richness were not influenced by the physical disturbance and this result was not in accordance with predictions of the HPI and MED. On the other hand, the frequency affected the faunal composition suggesting that some groups demand a longer period to colonize the substrate. Although, we recognize that some groups are affected by the disturbance frequency, the most part of the stream fauna should have a higher mobility and resilience, maybe as a reflect of the higher dynamism of this stream, in which is possible to observe that the substrate moves in a higher or lower rate depending on the rain intensity. Our results suggest that the experimental disturbance generate unoccupied patches which were promptly occupied by the major part of the taxa of aquatic macroinvertebrate fauna. Therefore, the colonization capacity of the different taxa and the redistribution between occupied and unoccupied patches should have a fundamental role on the fauna dynamics in the studied stream.

Texto completoIn this thesis we investigate the role of some of the most important factors in structuring EPT fauna in streams. In the first chapter, we discuss the effects of stream size, type of mesohabitat (riffles and pools) and season (rainy and dry) on the abundance, richness and composition of Ephemeroptera, Plecoptera and Trichoptera (EPT). According to our results, the abundance responded significantly to the interactions between mesohabitat type and size of the stream, and between season and size of the stream. Richness was significantly influenced by the size of the stream. Additionally, both the mesohabitat type and size of the stream significantly affected the faunal composition (DCA I). The type of mesohabitat can be considered a good predictor of EPT fauna, even in a highly seasonal system like the streams studied here. In the second chapter, we present equations representing the relative body size (body length and width of head capsule) for EPT taxa. Considering the data obtained, it is recommended, where possible, using the length of the body and only equations with R2 above 0.65, which may be useful when general information on the EPT biomass is necessary. This chapter supported the Chapter III. In third chapter we discuss the patterns of frequency distribution of body size and the relationship between body size and abundance of EPT. Our results show that regardless of the stream, the type of mesohabitat and the season, in general, the data on body size fit the normal distribution. Considering the relations between body size and abundance, the data of 50% of EPT assemblages analyzed individually fit the pyramidal shape. In any case, we observed negative linear relationship, therefore, our data disagree with the Energy Equivalence Rule. Our results suggest that a single factor (e.g. energy balance) is insufficient to explain the relationship between size and abundance of EPT in highly variable environments such as streams studied here.

O objetivo deste estudo foi investigar a estrutura da comunidade e a distribuição da fauna de Chironomidae em três mesohabitats: folhiço correnteza, folhiço remanso e sedimento remanso, em um córrego de primeira ordem na Mata Atlântica localizada na região sudeste do Brasil. As coletas foram realizadas nos meses de julho, agosto e setembro de 2007 (período seco) e janeiro, fevereiro e março de 2008 (período chuvoso), usando o amostrador Surber (malha 250 um) por um período de 30 segundos para cada mesohabitat. As amostras foram fixadas em formol a 4% e posteriormente no laboratório foram lavadas em peneira com malha 0,2Imm, triadas sob microscópio estereoscópico e os espécimes identificados em nível de gênero ou morfotipo. Para análise da estrutura da comunidade de Chironomidae de cada mesohabitat nos dois períodos de estudo, foram calculadas a riqueza taxonômica, a diversidade de Shannon, equidade de Pielou e o índice de dominância (ID) para cada táxon. A análise de agrupamento indicou que a pluviosidade foi um fator com forte influência na variação da estrutura da fauna de Chironomidae nos mesohabitats de folhiço em correnteza e remanso, e com menor influência no sedimento em remanso. Através da Análise de Correspondência e do Método do Valor Indicador foi possível observar a associação dos táxons com mesohabitats específicos e/ou período sazonal. Os substratos folhiço e sedimento foram favoráveis ao estabelecimento das larvas de Chironomidae apresentando alta riqueza e diversidade. O tipo de substrato e a precipitação foram os principais fatores que determinaram a estrutura e a distribuição espacial e temporal da fauna. Os resultados obtidos reforçam a importância da mata ciliar para a heterogeneidade de habitats em escala local, que favorece a diversidade de espécies em córregos de baixa ordem.
The aim of this study was to investigate the structure and distribution of the Chironomidae fauna in mesohabitats of litter from riff1e areas, litter from pool areas, and sediment in pool areas in a first-order Atlantic Forest stream located in southeastem Brazil. The collections were carried out in the months of July, August and September of 2007 (dry season) and January, February and March of 2008 (rainy season), using a Surber sampler (250 um mesh) for a period of 30 seconds for each mesohabitat. The samples were fixed in formaldehyde solution 4%, and then washed in current water and passed through a sieve with a 0.21mm mesh, sorted in a stereoscopic microscope and identified to genus level or morphotype. ln order to analyze the structure ofthe Chironomidae community in each mesohabitat sampled in the two periods of study, the richness, the Shannon's diversity index, Pielou's evenness and the dominance index were calculated. Cluster analysis indicated that precipitation was a factor with a great influence on the variation of the structure of the Chironomidae fauna in mesohabitats from litter in riffle areas and in pool areas, with low influence on sediment in pool areas. Through the Correspondence Analysis and the lndicator Values Method it was possible to observe the association of the taxa with specific mesohabitats and/or the seasonal period. The substrates litter and sediment were suitable to the establishment of Chironomidae larvae showing high richness and diversity. The type of substrate and the precipitation were the major factors that determined the structure and spatial and temporal distribution of the fauna. The results obtained reinforce the importance of the Riparian Forest to the heterogeneity of habitats on a local scale, a fact that allows the specie diversity in low order streams.

Texto completoThe present study had the aim to test the effects of the substrate complexity and of the mesohabitat (pools and riffles) on the richness, abundance and composition of Chironomidae (Diptera) in streams. The experiment took place in 12 streams of Central Brazil. In each stream, two plastic trays were put in each one of the two studied mesohabitats (pool and riffle), one with higher complexity substrate and one with lower complexity substrate. These substrates were kept in the streams for 20 days. The effects of substrate complexity and of mesohabitat were not significative neither on the standarized richness nor on the abundance. On the other hand, the effect of mesohabitat was significative on the faunistic composition. The first axis of DCA (33% of variability) separated cleanly the fauna in pools from those in riffles. The indicator species analysis showed that Chironomus sp., Ablabesmyia sp.1, Ablabesmyia sp.2, Djalmabatista sp., Fittkauimyia sp., Labrundinia sp. indicated pools, and Paratendipes sp., Polypedilum sp.2, Pentaneura sp., Rheotanytarsus sp.1, Corynoneura sp.2, Cricotopus sp.2, Lopescladius sp., Nanocladius sp.2, Parametriocnemus sp. and Thienemanniella sp. indicated riffles.

Texto completoFreshwater ecosystems are threatened by several pressures worldwide. Water pollution and eutrophication, the degradation and fragmentation of aquatic and riparian environments, overexploitation of resources, the dispersion of non-native species and more recently climate change have contributed to the loss of biodiversity and ecological integrity of rivers. For this reason, river conservation and management are essential to guarantee all associated ecosystem goods and services, this taking into account the biotic and biotic factors. Which leads to the objectives of the present study which were: 1) to evaluate the impact of abiotic factors on the biological quality of a watercourse, the river Fervença belonging to the drainage bassin of River Sabor (NE of Portugal), subject to anthropic pressures, and 2) to determine the influence of biotic factors, namely the complex relationship between fish and bivalves, in the ecological integrity of lotic systems. In the spring of 2020, abiotic (i.e. water quality and habitats) and biotic (i.e. macroinvertebrates and fish) characterization of 7 sampling sites were made, using the Water Framework Directive protocols. The results showed a marked decrease in the quality of water, habitats and biota in sampling sites located downstream of the city of Bragança, as a result of the input of contaminants from the urban environment, despite the presence of a wastewater treatment plant (WWTP). The degradation of abiotic conditions has led to the disappearance of species sensitive to pollution and to the loss of biodiversity, biotic relationships and ecological functions in the aquatic system. In this context, the relationship between a bivalve, the unionoid Anodonta anatina, and the fish fauna present in the river Sabor was studied. Four native Iberian species (Luciobarbus bocagei, Squalius alburnoides, Squalius carolitertii and Pseudochondrostoma duriense) and one non-native species (Alburnus alburnus) were tested in the laboratory. All fish species functioned as viable hosts for Anodonta anatina due to the wide distribution of this bivalve, although the higher rates of metamorphosis were found for a native species, Squalius carolitertii. For the conservation and management of NE Portugal's aquatic systems, measures for the rehabilitation of disturbed ecosystems and the conservation of priority habitats are essential, namely for threatened native species.
Os ecossistemas de água doce estão ameaçados por várias pressões à escala mundial. A poluição e eutroficação da água, a degradação e fragmentação de ambientes aquáticos e ribeirinhos, a sobreexploração de recursos, a dispersão de espécies não nativas e mais recentemente as alterações climáticas têm contribuído a perda de biodiversidade e integridade ecológica de rios. Por tal motivo, a conservação e gestão de rios é fundamental para garantir todos os bens e serviços ecossistémicos associados. O presente estudo teve como objetivos: 1) avaliar o impacto de fatores abióticos na qualidade biológica de um curso de água, o rio Fervença (NE de Portugal), sujeito a pressões antrópicas, e 2) determinar a influência de fatores bióticos, nomeadamente da relação complexa entre peixes e bivalves, na integridade ecológica dos sistemas lóticos. Na primavera de 2020 foi feita a caracterização abiótica (i.e. qualidade da água e habitats) e biótica (i.e. macroinvertebrados e peixes) de 7 locais de amostragem, com recurso aos protocolos da Diretiva Quadro da Água. Os resultados evidenciaram uma diminuição acentuada da qualidade da água, dos habitats e do biota nos locais situados a jusante da cidade de Bragança, como resultado do input de contaminantes do meio urbano, apesar da presença duma estação de tratamento de águas residuais (ETAR). A degradação das condições abióticas levou ao desaparecimento de espécies sensíveis à poluição e à perda de biodiversidade, relações bióticas e funções ecológicas no sistema aquático. Neste âmbito, foi estudada a relação entre um bivalve, o unionídeo Anodonta anatina, e a fauna piscícola presente no rio Sabor. Foram testadas, em laboratório, quatro espécies nativas da Ibéria (Luciobarbus bocagei, Squalius alburnoides, Squalius carolitertii e Pseudochondrostoma duriense) e uma espécie não nativa (Alburnus alburnus). Todas as espécies piscícolas funcionaram como hospedeiros viáveis de Anodonta anatina em virtude da distribuição alargada deste bivalve, embora as taxas superiores de metamorfose tivessem sido encontradas para uma espécie nativa, o Squalius carolitertii. Para a conservação e gestão dos sistemas aquáticos do NE Portugal são essenciais medidas de reabilitação de ecossistemas perturbados e a conservação de habitats prioritários, nomeadamente para as espécies nativas fortemente ameaçadas.
