Abstract	Resource use by organisms is mainly influenced by factors such as the morphology of individuals and the diversity and abundance of resources. For omnivores, the influence of these factors is more complex, as they have a morphology adapted to access different trophic levels, and any change in the environment can affect the quality or availability of resources. The aim of this study was to evaluate the effect of biotic and abiotic factors on the use of resources by omnivorous fish. We analysed the diet of 107 individuals of Astyanax lineatus in headwater streams in the Pantanal plateau, Brazil. We analysed the influence of body size and the characteristics of streams on the dietary composition, proportion of allochthonous items, trophic niche width and trophic position of individuals. These alimentary parameters were mainly influenced by body size and environmental variables, such as stream vegetation cover, flow, dissolved oxygen and conductivity. Allochthonous resources were more important to the diet of our model fish. We observed that larger individuals are more specialists than medium‐sized individuals and the trophic position decreases with increasing body size. Basically, three factors may have contributed to these results: large supply of carbon‐rich resources; morphology adapted for the consumption of larger, harder and carbon‐rich foods; and the interaction of increased body size and the high temperatures in the Neotropical region that can increase the demand for carbon for energy production.

Abstract	Ecological literature offers a myriad of methods for quantifying β diversity. One such method is determining BDₜₒₜₐₗ (BD), which, unlike other methods, can be decomposed into meaningful components that indicate how unique a sampling unit is regarding its composition (local contribution) and how unique a species is regarding its occurrence in the community (species contribution). Despite this advantage, the original formulation of the BD metric only assesses taxonomic variation and neglects other important dimensions of biodiversity. We expanded the original formulation of BD to capture variation in the functional and phylogenetic dimensions of community data by computing two new metrics—BDFᵤₙ and BDPₕy—as well as their respective components that represent the local and species contribution. We tested the statistical performance of these new metrics for capturing variation in functional and phylogenetic composition through simulated communities and illustrated the potential use of these new metrics by analyzing β diversity of stream fish communities. Our results demonstrated that BDPₕy and BDFᵤₙ have acceptable type I error and great power to detect the effect of deep evolutionary relationships and attributes mediating patterns of β diversity. The empirical example illustrated how BDPₕy and BDFᵤₙ reveal complementary aspects of β diversity relative to the original BD metric. These new metrics can be used to identify local communities that are of conservation importance because they represent unique functional, phylogenetic, and taxonomic compositions. We conclude that BDPₕy and BDFᵤₙ are important tools for providing complementary information in the investigation of the structure of biological communities.

Abstract	This study aimed to determine the concentration of metals in the water and in the liver tissue of fish (Anodus orinocensis, Hemiodus unimaculatus, Curimata vittata, and Plagioscion squamosissimus) in the lower Araguari River. Steps were also taken to estimate any difference in metal bioaccumulation in the liver of fish species at different trophic levels, determine any correlations between metals found in hepatic tissue of fish species relative to that found in river water, and evaluate the bioaccumulation factor. The metals analyzed in the water in the lower Araguari River (Cd, Pb, Fe, Hg, Cu, and Zn) exceeded the limits considered safe for aquatic life. We found a significant difference only in the bioaccumulation of Pb between A. orinocensis and C. vittata (F = 4.65, p = 0.005) and Cr between A. orinocensis and H. unimaculatus (F = 3.12, p = 0.03). Species of distinct trophic levels showed differences in metal concentration in liver. Cd and Cu showed bioaccumulation factor above 100, especially Cu with a relatively high value, for all fish species. The bioaccumulation of metals in the liver of fish species showed a positive correlation with the metals detected in the water of the Araguari River. In this sense, the lower course of the Araguari River is undergoing some type of environmental stress, making this study of additional valuable in diagnosing environmental quality pursuant to the development of environmental monitoring projects in order to guarantee the safety and maintenance of aquatic life.

Abstract	The development of multimetric indices (MMIs) to measure the biotic condition of aquatic habitats is based on metrics derived from biological assemblages. Considering fish assemblages, the inconsistencies in metrics responses outside of the places where they were developed limit MMI transferability and applicability to other locations, requiring local calibration. The factors behind the low transferability of these MMIs are still poorly understood. We investigated how environmental dissimilarity and spatial distance influence the transferability of metrics generated from local stream fish assemblages to other regions. We also tested whether functional and taxonomic metrics respond differently to the spatial distance. We used data from 239 fish assemblages from streams distributed across a Brazilian, the upper Parana basin and characterized each site according to the level of anthropogenic disturbance at the landscape scale using an Anthropogenic Pressure Index (API). We divided the upper Parana basin into sub-basins and used two of them to create template response models of the metrics in relation to the API. We used these response models to predict the responses outside the template sub-basins. Our response variable representing a metric of transferability was the absolute difference between metric's predicted and observed value for each site (prediction error). We thus modeled the prediction error in relation to the predictor variables that were i) the environmental dissimilarity between each site with the average of the sites from template sub-basins (climatic, topographic and soil type variables) and ii) the spatial distance (overland and watercourse distance) between each site and the center of the template sub-basin. We found that errors in metric predictions were associated with both environmental dissimilarity and spatial distance. Furthermore, functional and taxonomic metrics responded equally to spatial distance. These results indicate the need for local calibration of metrics when developing MMIs, especially if the protocols already available come from distant and environmentally dissimilar places.

Abstract	This study aimed to evaluate water quality using limnological parameters in two sub-basins of the Negro and Apa Rivers, along with the composition and structure of the landscape around the locations sampled in the two sub-basins and their possible contribution to the loss of water quality. We also set out to identify the genotoxic effects on the erythrocytes of Prochilodus lineatus and Leporinus friderici. In particular, we quantified total Cr, Ni and Pb in the muscle of these fish species to determine which genotoxic changes are related to the concentration of metals detected in the fish from these two sub-basins of the Paraguay River Basin. The sub-basin of the Apa River presented a greater proportion of surrounding pastureland in relation to the basin of the Negro River. The erythrocytes of P. lineatus showed a significant difference between the sub-basins for nuclear pyknosis, binucleated cells and lobed nuclei (p < 0.05). In L. friderici, vacuolated nuclei, nuclear pyknosis and lobed nuclei alterations also showed a significant difference between the sub-basins (p < 0.05). The genotoxicity index of the Apa River sub-basin presented higher frequencies of nuclear alterations in P. lineatus and L. friderici (p < 0.05), compared to the Negro River sub-basin. The concentration of total Cr, Ni and Pb in the muscles of P. lineatus and L. friderici in the Negro River sub-basin leads to genotoxic damage, mainly from the induction of lobed nuclei. Based on our results, it can be concluded that toxicogenetic effects in native fish species are an important source of environmental diagnosis in the Upper Paraguay River Basin.

Abstract	No presente estudo analisamos a existência de diferenciação na morfologia de populações isoladas de Corydoras aeneus (Gill, 1858). Quatorze caracteres morfométricos foram utilizados para a avaliação na morfologia de 14 populações isoladas das bacias dos rios Paraná e Paraguai. Verificamos a existência de diferenciação morfológica com auxílio da Análise de Função Discriminante. Utilizamos o teste de Mantel para observar se existia relação entre a similaridade morfológica e a distância geográfica. Após, realizamos uma análise de entre a similaridade morfológica e as características ambientais dos riachos. Constatamos, que existe diferença significativa na morfologia das espécies entre os locais (Wilk’s Lambda= 0,02; F(182,935)= 1,92; p<0,001). Existe correlação significativa entre a morfologia das espécies e as características dos locais coletados (Mantel r= 0,62, p= 0,01). As diferenças na morfologia das populações foram congruentes com as diferenças nas características dos riachos estudados. Desta forma, ao longo do tempo evolutivo foram selecionados os indivíduos que apresentavam características que conferiam maior adaptação às características ambientais, independente da distância geográfica entre estas populações estudadas.
