ABSTRACT The upper Paraná river floodplain is a strategic area for the Brazilian biological and environmental patrimony and contains several conservation units. We aimed to record the occurrence and the geographic distribution of microalgae in this floodplain during 30 years of research carried out by the Center for Research in Limnology, Ichthyology and Aquaculture - State University of Maringá. We consulted 80 publications (national and international journals and books published from 1986 to 2016). We considered only published works that referenced algae at the generic and infrageneric levels. The results indicated 938 species of algae (562 periphytic, 482 planktonic), which 103 co-occur in the two habitats. Cosmarium was the richest genera for periphyton and Traquelomonas for phytoplankton. This study increased the knowledge of microalgae biodiversity in Brazil and provided data for future ecological and biogeographic studies.

Abstract Aim Contributing to taxonomic knowledge on Pigmented Euglenophyceae at the Upper Paraná River Floodplain by enlarging the biodiversity survey in this ecosystem, in addition to contributing to the knowledge on the geographical distribution of this group in Brazil. Methods Quarterly samplings in the limnetic region of a floodplain lake between February 2000 and March 2009, numbering 30 samples obtained from both vertical and horizontal trawls using plankton net of a 15 µm-mesh aperture and subjected to Transeau-solution preservation. We prepared temporary slides and analyzed in order to have the organisms identified, measured and photographed through digital camera, directly using an Olympus binocular optical microscope with a 400x/1000x magnification. The analysis included the calculation of Constancy (C) for the sample of each species. Results 36 taxa were identified. Genus Trachelomonas Ehr. emend. Defl. had the best representation, with 20 taxa. Among the taxa surveyed, 53% (19 taxa) constituted new records of occurrence for the Upper Paraná River Floodplain. The taxa recorded as frequent (33.3%) are considered cosmopolitan and present wide geographical distribution throughout Brazil; however, most of the taxa surveyed (67%) was classified as sporadic or rare, which is probably related to the high environmental variability observed along the study period. Conclusion Among the surveyed 19 taxa constituted new records of occurrence for the upper Paraná River floodplain and extended the geographical distribution of Euglenophyceae in Brazil.

Clinostomum Complanatum

The present paper represents the first study on the endoparasitic fauna of Potamotrygon falkneri and P. motoro in the upper Paraná River floodplain. Fishes were collected by fishing rod and gillnetting in different stations of the floodplain, from March, 2005 to September, 2006. Parasites were sampled, fixed and preserved according to specialized literature. About half of the analyzed fish were parasitized by at least one of the following species of endoparasites: Clinostomum complanatum, Genarchella sp. and Tylodelphys sp. (metacercaria) (Digenea); Acanthobothrium regoi, Rhinebothrium paratrygoni, Paroncomegas araya and Potamotrygonocestus travassosi (Cestoidea); Brevimulticaecum sp. (larva), Cucullanus sp., Echinocephalus sp. and Spinitectus sp. (Nematoda); and Quadrigyrus machadoi (Acanthocephala). Some species were already registered in Chondrichthyes and others were previously recorded in Osteichthyes from the study area. The study listed ten new records of parasites in the host P. falkneri, one new record in the host P. motoro and five new records in the locality upper Paraná River.

Rotifers present a high diversity in freshwater ecosystems. This study registered 11 genera and 42 species, new records for the Upper Paraná River floodplain. These results showed an increase in rotifer diversity in this ecosystem from 184 to 230 species. Among them some were registered only in the rivers and others in the lagoons. Thirty-seven species occurred in the littoral zone and 34 species in the pelagic; 3 species were registered only in the former zone and 2 species only in the latter. The lagoons presented the greatest richness, probably because of the greater stability, low current velocity, and the extensive aquatic macrophyte banks in the littoral zone of these environments as compared to those of the rivers. The highest number of species in the littoral habitats occurred due to the greater influence of shoreline vegetation, which allows greater habitat diversification. This fact contributed to the occurrence of non-planktonic species in the zooplankton samples.

The building of large dams in the Upper Paraná River basin altered the discharge regime at the Porto São José River section. The discharge regime has been altered since 1972, but the changes intensified after the Porto Primavera damming, in late 1998. Considering that discharge control affects the relationship between channel and floodplain, this work aimed to evaluate the intensity of the discharge control that resulted from the operation of the Porto Primavera Dam. To achieve this objective, statistical analyses were carried out based on the Porto São José Fluviometric Station historical series of river level readings and discharge, between 1964 and 2007. Results showed that the average discharge increased from 1964 to 1981 and diminished after river damming. The increase of average discharge rates was followed by an increase of the duration of higher discharges at different levels of geomorphologic and limnological importance, and the reduction of average discharge during the last observed period was followed by a disproportionate decrease in the duration of the abovementioned discharges. Moreover, it is clear that the relationship between fluviometric level and fluvial discharge changed, which implies that a certain river level reading represents a higher discharge than necessary before river damming.
