Abstract	An initial and comprehensive map of ecological regions across the conterminous United States was provided by Omernik in 1987. Because that paper was the most-cited published by the Annals of the American Association of Geographers, we sought to assess and quantify its contribution to science. To do so, we conducted a scientometric analysis to address the following main questions: 1) What are the temporal and spatial citation trends? We expected that Omernik's paper would still be employed 36 years after its publication, and mostly in the United States of America. 2) For what types of environments and organisms has it been applied? Based on its generality, we expected that it had been applied to both terrestrial and aquatic ecosystems. 3) What are the main applications of Omernik's article? We predicted that it would mostly be used for describing and delineating study sites and management areas, as well as for selecting regional reference sites. The number of citations presented a positive temporal increase, indicating its continued applicability. Most papers dealt with aquatic environments, mainly in streams carried out predominantly in the United States of America, as was one of its earliest applications. The usefulness of ecoregions for assessing and managing biotic and abiotic patterns and distributions were the main topics addressed by scientists. Ecoregions have offered a general framework for developing regional expectations and rational regional management policies across large areas, as was their original intent. In addition, ecoregion maps were used for communicating patterns-or the lack of them-to interested scientists, citizens, and decision-makers. That comprehensiveness of Omernik's ecoregion approach has led to its widespread applicability and continued usefulness to a diverse set of scientific and management disciplines.

Abstract	Multimetric indices (MMIs) are common tools used to assess the biological status of ecosystems. However, not all the components of biological integrity have been equally addressed, since most of MMIs do not consider nonnative species, which are a great threat to ecosystems integrity. We performed a systematic review of how nonnative species have been considered in MMIs to assess biological conditions worldwide. Using a systematic review of the literature we identified to what extent nonnative species have been included as a disturbance factor for determining reference conditions and if specific metrics related to both nonnative and native species have been taken into account in the MMIs around the world. We also identified the most frequent species origin metrics that have been included in the MMIs. We searched for articles published in English up to 2016 that applied or developed an MMI in the Web of Science database (Clarivate Analytics). Following the PRISMA guidelines, we analyzed 409 articles. We found that only 1.2% of the studies used nonnative species as a disturbance factor in determining reference conditions. About 66% of articles did not test or did not provide the information if they tested metrics on native or nonnative species. Most of the articles (53%) that tested native or nonnative metrics were fish-based MMIs. We found 97 different metrics, of which 69% were related to native species, whereas 31% were related to nonnative ones. Native richness was the most used metric in studies that considered species origin (23.5%). Our main results evidence that nonnative species are overlooked in biomonitoring programs. Owing to the well-known impacts of them on ecosystem integrity, their inclusion in definition of reference conditions and in MMIs metrics should be considered as bioassessment criteria.

Abstract	Corydoras is the richest genus of Corydoradinae, and many of its species have not been identified to date. We characterized Corydoras carlae and Corydoras sp. by performing cytogenetic, morphometric, and molecular analyses to facilitate correct identification and species delimitation and contribute an understanding of the evolutionary process of this group of fish. Individuals of C. carlae were collected in the Florido River, a tributary of the Iguassu River upstream of Iguassu Falls, and individuals of Corydoras sp. were collected in the Poço Preto River, a tributary of the Iguassu River downstream of Iguassu Falls. Corydoras sp. presented an extra rDNA 5S marker in an interstitial position on the short arm of one of the chromosomes of the submetacentric pair 15. Mitochondrial (COI) and nuclear (RAG1) sequences were efficient in discriminating C. carlae and Corydoras sp. Both species had exclusive haplotypes, which suggests the absence of gene flow between species. Furthermore, species delimitation analysis (GMYC and ABGD) suggested two MOTUs for Corydoras specimens from the Iguassu River. Differences in morphometric proportions were also observed. Considering the data gathered in this study, C. carlae and Corydoras sp. comprise distinct evolutionary lineages that are probably undergoing a recent speciation process.

Abstract	Pirarucu is a carnivorous fish species from the Amazon river basin. There is growing interest in pirarucu farming, but scarce information for specific diets is a limitation. We analyzed the muscle tissue amino acid profile of pirarucu in order to estimate its amino acid requirements by using a diverse sample pool. Wild pirarucu was captured in the Araguaia and Caiapós river basins (Tocantins, Brazil). Farmed pirarucu was purchased from fish farms in the states of Maranhão and Tocantins (Brazil). Fish were sampled in two size classes: 1.66 ± 0.22 and 10.49 ± 1.07 kg body weight. Multivariate statistical analyses were applied to amino acid profiles among the groups, using R software with Vegan package. Muscle amino acid profiles varied according to pirarucu origin and size class. Estimated values can be adopted to formulate diets for pirarucu. Pirarucu fillet is a good source of essential amino acids for human consumption.

Abstract	We developed MMI models that combine responses of fish and benthic macroinvertebrates for the evaluation of the biotic integrity of streams. The MMI was developed using a dataset covering stream sampling sites in the South of Brazil. Reference streams were identified based on the physical and chemical conditions and riparian vegetation. Thirty-four metrics were calculated and evaluated for their range, redundancy, and responsiveness to the environmental perturbation. We applied a robust approach to select the most sensitive metrics and MMI models based on the complexity and ability of the index in distinguishing impacted and reference sites. The four best MMI models selected are composed of different combinations of the eight metrics: % fish herbivorous, fish evenness, fish abundance, % macroinvertebrate shredder; % macroinvertebrate predator; % macroinvertebrate tolerant, % macroinvertebrate swimmer, and % macroinvertebrate burrower. All of the MMI models selected presented good performance in distinguishing reference streams from those impacted by different forms of land use. This study is one of the few attempts to use more than one biological assemblage in a single-multimetric index. Accordingly, we believe that the unified MMI we developed could be a useful tool to assist in the conservation and management of water resources in Neotropical regions, specially, in the implementation of ecological integrity tools more cost-effectively.

Abstract	In 1981, James R. Karr's paper ‘Assessment of biotic integrity using fish communities’ provided the first description of a multimetric procedure to assess the biotic integrity of aquatic ecosystems. To assess the contribution of the Index of Biotic Integrity (IBI) and ideas proposed by Karr for the management of aquatic ecosystems, we carried out a scientometric analysis of the papers published from 1981 to 2011 that cited Karr's study. The papers were obtained from Thomson Reuters’ database (ISI Web of Knowledge) in October 2011. We used all papers that cited ‘Karr, 1981’ to assess temporal trends in citations and to identify which journals cited the index most frequently. A total of 93 papers were selected from the two journals that most frequently cited Karr's study, namely Hydrobiologia and Ecological Indicators. For each paper selected, we determined whether the study was empirical, theoretical, or methodological. For empirical papers we assessed the type of environment where the study was carried out, the indicator organisms used, and whether the IBI was applied. To identify which ideas suggested by Karr have been discussed in the literature, we assessed all papers found. In the time frame studied, 734 papers cited ‘Karr, 1981’. The number of citations increased significantly with time. Most papers that cited ‘Karr, 1981’ were empirical, carried out in rivers and streams, and used fish as bioindicators. The main ideas discussed in these studies were related to the creation and use of the IBI, as well as to limitations and difficulties in its application. Our results suggest that the ideas proposed by Karr have contributed to the conservation of aquatic ecosystems. However, criteria for choosing different metrics, as well as the definition of reference conditions, are issues that need to be addressed in order to make the IBI a more robust index.

Abstract	The biomonitoring of aquatic ecosystems in developing countries faces several limitations, especially related to gathering resources. The present study aimed at comparing the responses of fish and benthic macroinvertebrates to environmental change, to identify which group best indicates the differences between reference and impacted streams in southern Brazil. We determined reference and impacted sites based on physical and chemical variables of the water. For the analysis and comparison of biological responses, we calculated 22 metrics and submitted them to a discriminant analysis. We selected from this analysis only six metrics, which showed that the two studied assemblages respond differently to environmental change. A larger number of metrics were selected for macroinvertebrates than for fish in the separate analysis. The metrics selected for macroinvertebrates in the pooled analysis (i.e., fish and macroinvertebrates together) were different from those selected in the separate analysis for macroinvertebrates alone. However, the metrics selected for fish in the pooled analysis were the same selected in the separate analysis for fish alone. The macroinvertebrate assemblage was more effective for distinguishing reference from impacted sites. We suggest the use of macroinvertebrates as bioindicators of Neotropical streams, especially in situations in which time and money are short.

Abstract	The ichthyofauna from 3 streams (Água Boa, Perobão, and Santa Maria) to the lower Iguatemi River were inventoried, which is located in the upper Paraná river basin, in Mato Grosso do Sul state, Brazil. Sites in the upper, intermediate, and lower portions of each stream were quarterly electrofished from March to December 2008. All sampled fish (n = 6,816 individuals) represented 43 species of 5 orders, and 16 families. The most abundant species was Phalloceros harpagos (63.5%), followed by Astyanax aff. paranae (10.6%), Hypostomus ancistroides (5.9%), Gymnotus inaequilabiatus (3.4%), and Knodus moenkhausii (2.7%). Despite the high ichthyofauna richness in the lower portion of Iguatemi River, the need to implement and/or expand soil conservation practices and riparian forest restoration is of utmost importance to maintain these populations in the long term.
