Última The invertebrate's community in adjacent Alto Iguaçu's anthropic lakes of different environmental factors Biota Neotropica Krawczyk,Ana Carolina de Deus Bueno; Baldan,Lucíola Thais; Aranha,José Marcelo Rocha; Menezes,Márcia Santos de; Almeida,Cyntia Vilasboas. Environmental differences occur between lentic and lotic communities' establishment, especially because of water time residence. Here we used a combination of field measurements and statistical analysis to evaluate the influent factors on the aquatic macroinvertebrates' composition and structure in 15 anthropogenic lakes from Alto Iguaçu's region. Macroinvertebrates were sampled from the marginal vegetation (with or without macrophytes) and sediment. Chemical parameters ranged among the anthropogenic lakes, mainly those which are connected to the Iguaçu River, beyond the presence or absence of macrophytes, interfering on the community's structure. Lake's morphometric data were measured in each lake and its relation to community was tested. The community...

Studies were performed to determine the growth curves in length and weight for Pimelodella pappenheimi in the "das Pombas" stream, a coastal stream susceptible to the flash flood phenomenon. Samples were collected from September-95 to February-97, monthly, using electric fishing. The fishes were measured in total length and weight. A total of 156 pairs of otholits were taken for ring reading. The Ford-Walford transformation allowed the use of von Bertallanffy expression. The pale ring formation was annual, and it occurred between the summer and the autumn. This species grews in length according to Lt=15.86 (1-e-0.57(t+0.1551) ) equation and in weight according to Wt= 24.23 (1-e-0.57(t+0.1551) )3.12. The increase in length was faster until the second year... Tipo: Info:eu-repo/semantics/article Palavras-chave: Growth; Coastal Stream; Pimelodidae.

Mimagoniates microlepis was collected between January and December/2002. Three sample points were chosen at higher, medium and lower portions of Ribeirão river, located at the east of Paraná state. The reproduction period was observed by the frequency of gonad developmental stages, variation of the gonosomatic relation (RGS) and gonad condition (K). The average length at the first sexual maturity (L50) and the average length when 100% of individuals were adults (L100) were calculated. The intensity of the reproductive activity (IAR) was estimated at each sample point. The reproduction period started in the winter and ended at the end of spring. The high values of IAR encountered demonstrated that the reproductive activity occurred in the whole study area,...

Aspects of the biology of D. langei were studied at different sites along a longitudinal gradient formed by the Ribeirão stream basin, a Neotropical stream of the Atlantic Forest, southern Brazil. Differences were observed in population structure and reproduction along the longitudinal gradient and during the study period. Juvenile fishes occurred in high abundance, mainly in the downstream site after the rainy months. Adults occurred mainly in the intermediate and upstream sites. During their life cycle, adults optimise their reproductive strategy by concentrating the reproductive period with total spawn in a short time interval before summer rains dragged the juvenile, larval forms and/or eggs downstream. The downstream site was characterized by a wide...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132008000600014 Population structure and condition factor of Pseudotothyris obtusa (hypoptopomatinae) from three coastal streams in southern Brazil BABT Takeuti,Denise de Freitas; Verani,José Roberto; Aranha,José Marcelo Rocha; Menezes,Márcia Santos de. Population structure features and condition factor of Pseudotothyris obtusa were compared between three coastal streams in southern Brazil. Fishes were monthly collected through electric fishing and measured in the total length. Fifteen fishes from each stream were dissected to identify their sex. The structure in size, sex ratio and young/adults ratio of populations were analysed and the length-weight relationship was obtained. The condition factor (K1) and the relative condition factor (Kn) were calculated for each stream. Fishes were grouped in 11 lenght classes of 3mm. The intermediate and bigger size classes were preponderant in the "Mergulhão" and "Colônia Pereira" streams, and the smaller and intermediate ones in the "Ribeirão" stream. Females...

The population structure, reproductive aspects and feeding of Phalloceros caudimaculatus (Hensel, 1868), Poecilia vivipara Bloch & Schneider (1801), Phalloptychus januarius (Hensel, 1868) e Jenynsia lineata (Jenyns, 1842) were studied in five sampling stations in the Ubatiba stream, municipality of Maricá (State of Rio de Janeiro, Brazil). In relation to the population structure, P. caudimaculatus was more representative upstream; P. vivipara mid-stream and downstream; P. januarius and J. lineata downstream. The species presented preponderance of females, except in the intermediate length classes. The occurence of imatures and females with young pointed out a long reproductive period and favoured areas for reproduction of the four species. The...
