Última Planktonic and non-planktonic rotifers in two environments of the Upper Paraná River floodplain, state of Mato Grosso do Sul, Brazil BABT Bonecker,Cláudia C.; Lansac-Tôha,Fábio A.; Rossa,Dayane C.. Investigations were carried out for the composition and occurrence of rotifer taxa of different forms and sizes during two distinct hydrological periods, in two environments (river and lake). Two sampling stations were established in open water of each environments. Surface samples were taken daily for 14 days. The faunistic similarity between the environments was established using Jaccard's index. One hundred and fourty three taxa were identified. The largest number of taxa was recorded in the river. Faunistic similarity between these environments was greater during high water. The planktonic taxa predominated and the difference for the non-planktonic ones was not marked. Non-planktonic taxa predominated in the river, while both types were numerous in the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Rotifers; Size classes; Habitat; Floodplain; Brazil. Ano: 1998 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89131998000400009 Daily variation of zooplankton abundance and evenness in the Rosana reservoir, Brazil: biotic and abiotic inferences Iheringia, Sér. Zool. Takahashi,Érica M.; Lansac-Tôha,Fábio A.; Dias,Juliana D.; Bonecker,Claudia C.. The zooplankton community presents stochastic temporal fluctuation and heterogeneous spatial variation determined by the relationships among the organisms and environmental conditions. We predicted that the temporal and spatial zooplankton distribution is heterogeneous and discrete, respectively, and that the daily variation of most abundant species is related to environmental conditions, specifically the availability of resources. Zooplankton samples were collected daily at three sampling stations in a lateral arm of the Rosana Reservoir (SP/PR). The zooplankton did not present significant differences in abundance and evenness among sampling stations, but the temporal variation of these attributes was significant. Abiotic variables and algal resource... Tipo: Info:eu-repo/semantics/article Palavras-chave: Temporal variation; Rotifers; Microcrustaceans; Coexistence; Competition.
