Resumo: | Population dynamics of Drepanotrema cimex (Moricand, 1839) (Mollusca: Basommatophora: Planorbidae) in Barigüi Park, Curitiba City, State of Paraná, Brazil. The ecology of the freshwater snail Drepanotrema cimex (Moricand, 1839), an intermediate host of trematode larvae, is little known in Brazil. We analyzed the population dynamics of D. cimex in Barigüi Park, Curitiba, Brazil. Collections for the survey were realized at three sites that were at different distances from the Barigüi River and had distinct water plant species. In total, 278 snails were collected, and the highest sampling rate was where Paspalum sp. and Alternanthera philoxeroides (Mart.) Griseb. occurred. A higher occurrence of D. cimex in the autumn suggested that the adult stage culminates in this season, resulting from the previous rainy period that seems to support the reproduction of snails in the summer. However, the water temperature had no correlation with the total quantity of snails. The mean shell diameter did not show any correlation either with the water temperature or with the seasons. We recorded intraspecific variations in the color of the shells among the collections from the different sites. |

Objetivou-se analisar a dinâmica populacional de D. cimex associada às macrófitas aquáticas do Parque Barigüi, Curitiba, Brasil. As coletas foram realizadas em três pontos do parque, que se diferenciavam pela distância até o rio Barigüi e pelo tipo de vegetação. Foram registradas 278 conchas, sendo mais freqüentes no local de predomínio das macrófitas Paspalum sp. e Alternanthera philoxeroides (Mart.) Griseb. A maior ocorrência no outono indicou que a fase adulta culmina nesta estação, como resultado do período de chuvas, que parece favorecer a reprodução dos indivíduos no verão. Contudo, não houve correlação da temperatura da água com o número total de caramujos e nem com diâmetro médio das conchas. Foram constatadas variações intraespecíficas na tonalidade das conchas nos três pontos amostrais.Universidade Federal de Santa Catarina2005-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21419Biotemas; v. 18 n. 2 (2005); 129-1412175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21419/19383Copyright (c) 2005 Marlus Bueno-Silva, Marta Luciane Fischerhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBueno-Silva, MarlusFischer, Marta Luciane2022-11-21T11:30:23Zoai:periodicos.ufsc.br:article/21419Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:30:23Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
