Abstract	Mining is an important human activity, but it strongly alters terrestrial and aquatic landscapes. Understanding the response of community-level descriptors is essential to plan monitoring and management strategies. In this context, we investigated differences in the environmental conditions and ichthyofauna (taxonomic and functional) structure in five pristine and four disturbed streams in a Central Amazon protected area sampled in the dry season of 2012. Additionally, we analyzed if taxonomic and functional structure exhibited similar spatial variation patterns among streams. Pristine streams exhibited higher richness and proportion of catfishes (Siluriformes) than disturbed streams, but no differences in the functional structure. The taxonomic and functional structure of the fish assemblages in the Saracá-Taquera National Forest varied concomitantly among the streams. Our results indicate that taxonomic-based metrics were more sensitive to the mining impacts in the Saracá-Taquera National Forest, probably because of the high functional redundancy of the local assemblages. We highlight the sensitivity of richness and proportion of siluriformes for monitoring stream fish assemblages in the Central Amazon.

Abstract	We provide length‐weight relationships (LWR) estimates for 45 species from the upper Tocantins River basin. Specimens were sampled by a standardized set of gill nets varying from 15 mm to 150 mm mesh size for 15 years (from 1995 to 2010) of field works. Field expeditions were carried out in three temporal bins with bimonthly samplings, (i) December 1995 to February 2000, (ii) February 2001 to December 2002, and (iii) February 2009 to December 2010, totalizing 46 field works. For all species, standard length (SL; 0.1 cm precision) and total weight (Wt; 0.01 g precision) were determined using a scale and a digital balance, respectively. From these 45 species, 28 have no previous LRW information in Fishbase, and we also provide new maximum standard length for 16 species. When data for at least 10 male or female individuals were available, we also provided the LWR information separately by gender.

Abstract	The temporal and spatial distribution of the ichthyofauna was assessed in two streams, Caracu and São Pedro, affluents of the Rio Paraná, from March 1991 through February 1992. Samples were taken along the streams, using sieves (three sites on the Caracu and two on the São Pedro), and gill nets (two sites on the São Pedro). A total of 6,664 specimens belonging to 71 species were captured. CPE was calculated for each fishing gear. The data for cumulative frequency indicated that only the mouths of streams did not reach an asymptote. Constancy analysis showed that occasional and accessory species predominated. The spectrum of spatial diversity indicated that diversity increased toward the mouth of streams and temporal diversity increased in the high water season. The results of correspondence analysis for sieved fishes and Sørensen similarity for netted ones showed that the sites located at the same position on the streams were more similar than between adjacent sites in the same stream.

Abstract	Key to understand predator choice is the relationship between predator and prey abundance. There are few studies related to prey selection and availability. Such an approach is still current, because the ability to predict aspects of the diet in response to changes in prey availability is one of the major problems of trophic ecology. The general objective of this study was to evaluate prey selection by two species (Characidium cf. vidali and Pimelodella lateristriga) of the Mato Grosso stream, in Saquarema, Rio de Janeiro, Brazil. Benthos and fishes were collected in June, July and September of 2006 and January and February of 2007. Fish were collected with electric fishing techniques and benthos with a surber net. Densities of benthic organisms were expressed as the number of individuals per/m2. After sampling, the invertebrates were fixed in 90% ethanol, and, in the laboratory, were identified to the lowest taxonomical level. Approximately, seventy individuals from each species were selected randomly in each month. Fishes were fixed in 10% formalin in the field and transferred to 70 degrees GL ethanol in the laboratory. Fishes had their stomachs removed for subsequent analysis. Fish diet was described according to the numeric frequency method. The Manly Electivity Index was applied in order to verify prey selection. The most abundant families in both benthos and diet of both fish species were the same, indicating that these species consume mainly most abundant prey in the environment. We concluded that prey selection occurs even for preys that had small abundance in the environment. However, it is the availability of the macroinvertebrate resources that determines the major composition of items in diet of fish, demonstrating that the abundance is the factor that most influences the choice of prey.

Abstract	Twenty-two species were registered in the Ubatiba system with a predominance of Characiformes and Siluriformes followed by Cyprinodontiformes, Perciformes and Synbranchiformes. Among these species four were occasional with one or two sampled individuals and restricted to one or two of the nine studied sites; the other 18 species were constant with high densities in at least one site. Most of the sampled sites presented between 11 and 18 species, all largely distributed; except for the uppermost site, located right over a waterfall 4m high, which showed at least four species and for the confluence site that presented 18 species. Canonical Correspondence Analysis indicated that environmental variables explained a great part of the density and distribution patterns of the fish species, showing that community structure of each locality was independent from the longitudinal succession, theoretically expected by the River Continuum Concept, and hardly explained by local environmental characteristics.

Abstract	Platanichthys platana is considered a constant species in both Cabiúnas and Imboassica lagoons that are characterised by different marine and freshwater inputs, and anthropogenic influences. The stomach content analysis of P. platana captured between July 1991 and July 1993 revealed filamentous algae, detritus, eggs of benthic invertebrates, larvae of chironomids and bivalves as the main food sources in Imboassica lagoon. Small-sized cladocerans, copepods and shrimp larvae were the prevailing items in Cabiúnas lagoon. Seasonal food variations were noted for the fishes of Imboassica lagoon. Diet differences were highlighted within specimens lesser than 40 mm standard length in Imboassica lagoon, and were related to the increase of marine influence due to artificial sand barrier openings. Dissimilarities among size classes in relation to invertebrate larvae consumption were observed in fishes from Cabiúnas lagoon.

Abstract	Macro- and microscopic ovarian features of Hemiodus microlepis, H. ternetzi and H. unimaculatus were analyzed. Based on these features we proposed an ovarian maturation scale. The nine stages of the preliminary macroscopic fieldwork scale were reduced to five after microscopic analysis of ovaries. The microscopic analysis indicated a group-synchronous oocyte development common to the three species that were characterized as iteroparous synchronous spawners with a total spawning type. The remarkable thickness of the zona radiata layer and the large size of vitellogenic oocytes of Hemiodus ternetzi distinguished this species from the others.

Abstract	The Tocantins-Araguaia Basin is one of the largest river systems in South America, located entirely within Brazilian territory. In the last decades, capital-concentrating activities such as agribusiness, mining, and hydropower promoted extensive changes in land cover, hydrology, and environmental conditions. These changes are jeopardizing the basin's biodiversity and ecosystem services. Threats are escalating as poor environmental policies continue to be formulated, such as environmentally unsustainable hydropower plants, large-scale agriculture for commodity production, and aquaculture with non-native fish. If the current model persists, it will deepen the environmental crisis in the basin, compromising broad conservation goals and social development in the long term. Better policies will require thought and planning to minimize growing threats and ensure the basin's sustainability for future generations.

Abstract	Foram estudados as hábitos alimentares dos peixes engraulídeos Anchoa januaria e Cetengraulis edentulus na Baía de Sepetiba, Rio de Janeiro, de julho de 1983 a julho de 1985. Os itens alimentares e as estruturas morfológicas relacionadas à alimentação indicaram que a área superficial dos rastros branquiais de A. januaria e C. edentulus é mais eficiente para a filtração dos alimentos, do que as distâncias entre os mesmos. Estas estruturas morfológicas possibilitam uma seletividade no tamanho dos itens alimentares, resultando em formas distintata de obtenção do alimento, entre as duas espécies. A. januaria seleciona o zooplâncton, por captura dos itens alimentares, enquanto C. edentuluss é um fitoplanctófago filtrador. Anchoa januaria tem hábitos alimentares diurnos e explgra diferentes estratos da coluna d'água durante os períodos frio e quente.
