Fishes were collected at 36 sites in first order streams of Tibagi River basin, Paraná state, Brazil. A total of 2,669 individuals belonging to 47 species of 13 families and six orders were collected. The number of collected species represented 95.9% of the expected number of species for the studied area as estimated by Chao 1, and 93.4% by ACE, indicating an effective sampling. The highest richness was recorded in the tributaries at the lower region (Zone III) of the Tibagi River basin, with 33 species, including 16 species not found in the other regions of the basin. In the streams of the middle and upper regions (Zones II and I) each presented less richness, with 10 (two exclusive) and 25 (11 exclusive) species, respectively. This study shows a high geographic variation in the composition of fish fauna among zones, maybe related to historical and/or ecological influences.

During construction of the Furnas hydroelectric power dam in the upper rio Paraná basin in the early 1960s, the rio Piumhi drainage outflow was diverted into the headwaters of the São Francisco river basin. The rio Piumhi was a right bank tributary of the rio Grande, which unites with the rio Paranaíba to form the rio Paraná. The transposition allowed the entire fish fauna of the rio Piumhi and associated swamps, lakes, and tributaries to intermingle with the fish fauna of the São Francisco basin via the ribeirão Sujo, a right bank tributary of the São Francisco. The transposition of the watershed may have had a major impact on the current composition of the fish fauna of the upper rio São Francisco watershed.

This paper presents a taxonomic and biostratigraphic analysis of the monosaccate pollen grains related to the genera Costatascyclus Felix & Burbridge emend. Urban 1971, Circumplicatipollis Ottone & Azcuy 1988, Caheniasaccites Bose & Kar 1966, Stellapollenites Lele 1965 and Divarisaccus Venkatachala & Kar 1966 recorded in the Pensylvannian - Permian interval in the Paraná Basin. These genera are represented by seven species: Costatascyclus crenatus Felix & Burbridge 1967, Circumplicatipollis plicatus Ottone & Azcuy 1988, Caheniasaccites flavatus Bose & Kar 1966, Caheniasaccites elongatus Bose & Kar 1966, Caheniasaccites verrucosus (González-Amicón) Gutiérrez 1993, Stellapollenites talchirensis Lele 1965 and Divarisaccus stringoplicatus Ottone 1991. Among these species, C. verrucosus is recorded for the first time to the Paraná Basin. Based on analysis of samples from new localities, new slides of published sections, from scientific collections, and on the examination of available papers, synonymic lists are shown, modifying the ranges of certain species. Respective occurrences of the taxa in the other Brazilian intracratonic basins (Amazonas and Parnaíba) are also analyzed. Furthermore, main morphologic distinctive characters of these species are presented, to facilitate the identification and their use in biostratigraphic and paleoenvironmental analysis.

The fishes of the present study were collected in the headwater streams of the Sorocaba, Paranapanema and Ribeira de Iguape river basins during the dry period in 2010. A total of 2892 fishes, grouped in 53 species, were captured. The composition of the ichthyofauna captured in the streams of Sorocaba and Paranapanema river basin was greatly similar. On the other hand, the fish fauna of the streams of Ribeira de Iguape river basin were quite different from the ones captured in the others basins, with the occurrence of endangered species (Isbrueckerichthys epakmos and I. duseni) and exotic species (Misgurnus anguillicaudatus). The previous list of fish for the Sorocaba river basin increased with the addition of seven species of Characiformes, one Gymnotiformes and four Siluriformes.

AIM: The present study analyzed the spatial variation in fish species richness and composition in streams of the Ivinhema River basin, Upper Paraná basin, determining the relationship between local and regional descriptors of the fish assemblage organization; METHOD: From 2001 to 2011 we sampled 200 stream stretches, using different sampling methods. Local species richness and composition were analyzed using univariate and multivariate methods to detect patterns of variation in the fish assemblage organization; RESULTS: We identified 111 fish species in the streams, and estimated the occurrence of 117 fish species (CIα0.05 = 111 to 123) with lower species richness in headwater streams compared to the lower parts of the basin. The fish species recorded were predominantly of small size, and the mean size increased from the headwaters to the river mouth. The four most common species are widely distributed in the basin. However, 24 species are allocthonous to the Upper Paraná basin, and two species (Chaetobranchopsis australis and Apistogramma commbrae) are recorded here for the first time in the Upper Paraná basin. Altitude was the main determinant of local fish species richness and composition, and a discontinuity in assemblage organization (richness, composition, fish size) was detected at approximately 430 m a.s.l.; CONCLUSION: Streams of the Ivinhema River basin are inhabited mainly by small-sized fishes; and longitudinal variation, interacting with local characteristics, determines the fish assemblage patterns.

This study aimed to conduct an inventory of fish assemblages in small streams that are tributaries of large reservoirs in three previously unstudied regions of the Upper Paraná River basin. We sampled 117 streams from 1st to 3rd order in Araguari (Nova Ponte hydropower plant reservoir), Paranaíba (São Simão reservoir) and Grande (Volta Grande reservoir) drainages. In total, 20,696 specimens belonging to 100 species, 53 genera, 20 families and six orders were collected. Of these, 11,530 specimens and 41 species were recorded in Araguari, whereas 17 were exclusive to this drainage. In Grande drainage, 3,537 individuals belonging to 41 species (11 exclusive) and in Paranaíba, 5,629 specimens and 67 species (38 exclusive) were sampled. The mean richness per stream was 6.7 for Grande, 9.0 for Araguari and 10.9 for Paranaíba drainage. The predominant orders were Characiformes, 48% of the total richness, and Siluriformes, 36%. Three species were diagnosed as new: Astyanax sp. 1 (Grande and Paranaíba), Astyanax sp. 2 and Astyanax sp. 3 (both from Araguari), all from scabripinnis group. Another three were considered potentially new: Characidium sp. 1, Characidium sp. 2 and Rhamdiopsis sp. Among all records, eight species are not native from the Paraná basin: the exotics Oreochromis niloticus and Tilapia rendalli and the allochtonous Cyphocharax gillii, Hoplerythrinus unitaeniatus, Knodus moenkhausii, Poecilia reticulata, Roeboides descalvadensis and Trichomycterus brasiliensis. This study fills part of the existing knowledge gap about fish from small streams of the Paraná basin. Inventories of the fish fauna from these low-order water courses are important because they highlight their biodiversity relevance, including a significant number of unknown species. Thus, this study contributes to a better knowledge of the stream fish fauna of the upper Paraná River basin, as well as contribute to the establishment of strategies for conservation of this important component of aquatic biodiversity.

Abstract The objective of this study was to provide a comprehensive list of the fish fauna of headwater streams of the Miranda River in the Upper Paraguay River Basin. Our primary data set was constructed from sampling of fish using a rectangular sieve, trawl, and gill nets from 2004 to 2015. Our secondary data were derived from published reports conducted in the Miranda River Basin, in addition to taxonomic and distribution data from other studies conducted in the basin. All data were compiled, which in the end encompassed a period from 1999 to 2015. The datasets yielded a total of 143 species, 104 from the primary data (72.7%) and 39 from the secondary data (27.3%). Species were distributed among seven orders and 30 families were found in the Miranda River Basin. Characiformes and Siluriformes were the predominant orders, and the families Characidae and Loricariidae had the greatest number of species. Our results indicate a greater number of species compared to other studies of the Upper Paraguay Basin headwaters, likely due to the longer time frame covered by our primary and secondary datasets.

Abstract: In the present work, we conducted an extensive long-lasting inventory of the fishes, using different collection methodologies, covering almost the entire Pindaré River drainage, one of the principal tributaries of the Mearim River basin, an area included in the Amazônia Legal region, northeastern Brazil. We reported 101 species, just three of them being non-native, demonstrating that the composition of this studied fish community is majority composed of native species. We found a predominance of species of the orders Characiformes and Siluriformes, corroborating the pattern usually found for the Neotropical fish fauna. Similar to other studies, this inventory was mainly dominated by small characids, representing 21% of the species herein recorded. When comparing the present survey with other species lists published for this region (including the States of Maranhão and Piaui), we can conclude that the freshwater fish fauna of the State of Maranhão is probably still underestimated. We reported 41 more species, and one more species than Soares (2005, 2013) and Abreu et al. (2019) recorded for the entire Mearim River basin, respectively. We believe, however, that the number of species presented by Abreu et al. (2019) is overestimated. We compared our results with all other freshwater fish species inventories performed for the hydrological units Maranhão and Parnaíba sensu Hubbert & Renno (2006). With these comparisons, we concluded that our results evidenced that a high effort was put in the inventory here presented. The two works including more species recorded from coastal river basins of the hydrological units Maranhão and Parnaíba were the works published by Ramos et al. (2014) for the Parnaíba River basin, one of the main and larger river basin of Brazil, and the compiled data published by Castro & Dourado (2011) for the Mearim, Pindaré, Pericumã, and upper Turiaçu River drainages, including 146 and 109 species, respectively. Our survey recorded only 45 less species than Ramos et al. (2014), and eight less species than Castro & Dourado (2011). However, it is essential to emphasize that the number of species presented by Castro & Dourado (2011) is probably overestimated since they did not update and check the taxonomic status of the species of their compiled data. In several cases, they considered more than one name for the same species.

The Itapecuru is a relatively large river in the northeastern Brazilian state of Maranhão. During several expeditions to this basin, we collected 69 fish species belonging to 65 genera, 29 families and 10 orders. Characiformes and Siluriformes were the orders with the largest number of species and Characidae, Loricariidae, Cichlidae, Auchenipteridae and Pimelodidae were the richest families. About 30% of the fish fauna of the Itapecuru basin is endemic or restricted to northeastern Brazil. Just over a fifth (22%) of the species is also known to occur in the Amazon basin and only a few are more widely distributed in South American.

Abstract Brazilian laws allow the catch of some species as ornamental fish; however, in the absence of biological information, such catch can threaten species conservation. Therefore, this study aimed to offer population and reproductive information about Farlowella hahni in streams of the Ivinhema River Basin, Upper Paraná Basin. To accomplish this, a total of 165 F. hahni individuals were analyzed, including 109 females and 48 males, resulting in an important sex ratio difference from 1:1 (χ 2=19.97; p<0.001), indicating a predominance of females throughout the year. Females reach higher standard length than males. Males presented isometric Length-Weight Relationships, while females have positive allometric growth. Gonadosomatic index presented higher values from October through December. The mean fecundity was 100.3±36.4 of vitellogenic oocytes and was positively correlated with standard length (r=0.51; p=0.01). The data presented herein are the first for this species and suggest a need to carefully manage the F. hahni population, considering its low abundance and fecundity.
