Cyclopid copepods from samples of fauna associated with aquatic macrophytes and plancton obtained in lotic and lentic environments were obtained from the upper Paraná River floodplain (in the states of Paraná and Mato Grosso do Sul, Brazil). Macrophytes were collected in homogeneous stands and washed. Plankton samples, taken from the water column surface and bottom, were obtained using a motor pump, with a 70 mum mesh plankton net for filtration. Twelve taxa of Cyclopidae were identified. Among them, Macrocyclops albidus albidus, Paracyclops chiltoni, Ectocyclops rubescens, Homocyclops ater, Eucyclops solitarius, Mesocyclops longisetus curvatus, Mesocyclops ogunnus, and Microcyclops finitimus were new finds for this floodplain. Eight species were recorded exclusively in aquatic macrophyte samples. Among these species, M. albidus albidus and M. finitimus presented greatest abundances. Only four species were recorded in plankton samples, and Thermocyclops minutus and Thermocyclops decipiens are limited to this type of habitat. Among these four species, T. minutus is the most abundant, especially in lentic habitats.

In this paper, nine species of Monogenea were recorded parasitizing the gills of Hoplias aff. malabaricus from the Upper Paraná River. The host were collected by gillnets in different regions to the Upper Paraná River Floodplain between March 2010 and March 2011. The parasites were quantified, fixed and preserved according with specialized literature. All hosts analyzed were parasitized by monogeneans. The monogeneans species were recorded Urocleidoides malabaricusi, U. cuiabai, U. eremitus, U. brasiliensis, Cosmetocleithrum bulbocirrus, Vancleaveus janauacaensis, Anacanthorus sp., Dactylogyridae gen. sp. and Dactylogyridae gen. 1. sp.

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.

ABSTRACT We present a taxonomic treatment for Malpighiaceae Juss. from the Upper Paraná River floodplain, Brazil, where 20 species in 12 genera were recognized. An identification key, morphological descriptions, photo plates, and comments on distribution and ecology of the species are provided. Tetrapterys xylosteifolia is recorded for the first time in both Paraná and Mato Grosso do Sul States in Brazil.

The aim of this work was to determine the caloric density of leaves, stems and roots of aquatic macrophytes in different environments of the Baía subsystem (Baía river and Fechada and Guaraná lagoons) on the Upper Paraná river floodplain, in addition to identify the variability between ecological groups. Samplings of Eichhornia crassipes, Salvinia spp, Pistia stratiotes, Eichhornia azurea, Polygonum sp, Cyperaceae and Poaceae were carried out in February 2003. Spatial differences in the caloric densities were not observed for these plants. Caloric density values varied from 1906.9 cal/g dry weight (root) to 4675.0 cal/g dry weight (leaf). However, significant differences between the caloric content averages of the vegetative structures were observed only for Polygonum sp and Salvinia spp. In relation to the ecological groups, the highest average value was verified for the emergent macrophytes (3529.7 ± 722.5), which were significantly different from the floating ones (3056.5 ± 571.0). There was no difference between the sites included in the subsystem when the caloric densities were compared.
