Title A name given to the resource <b>Aspectos ecológicos da fauna endoparasitária de <em>Acestrorhynchus lacustris</em> (Lütken, 1875) (Characiformes, Acestrorhynchidae) da planície de inundação do alto rio Paraná, Brasil</b> - DOI: 10.4025/actascibiolsci.v25i2.2043 <b>Ecological aspects of endoparasite fauna of <em>Acestrorhynchus lacustris</em> (Lütken, 1875) (Characiformes, Acestrorhynchidae) on the Upper Paraná River floodplain, Brazil</b>- DOI: 10.4025/actascibiolsci.v25i2.2043 Creator An entity primarily responsible for making the resource Ricardo Massato Takemoto, Gilberto Cezar Pavanelli, Gislaine Marcolino Guidelli, Solange de Carvalho Description An account of the resource Foram analisados 51 espécimes de Acestrorhynchus lacustris (Lütken, 1875) coletados na planície de inundação do alto rio Paraná, entre fevereiro de 2000 a novembro de 2001. Desses, 35 (68,6%) estavam parasitados por pelo menos uma espécie de endohelminto. Foram encontradas oito espécies de endoparasitas: cinco nematóides (Contracaecum Tipo 1 larva de Moravec, Kohn e Fernades, 1993, Contracaecum Tipo 2 larva de Moravec, Kohn e Fernades, 1993, Contracaecum sp., Eustrongylides sp., Procamallanus sp.), dois digenéticos (Clinostomum sp., Rhipidocotyle gibsoni Kohn e Fernandes, 1994) e um acantocéfalo (Quadrigyrus torquatus Van Cleave, 1920). Contracaecum sp. e Q. torquatus mostraram-se positivamente associadas e tiveram suas abundâncias positivamente correlacionadas. Houve diferença significativa na prevalência e intensidade média de infecção de Q. Torquatus entre os sexos dos hospedeiros. Este parasita também apresentou correlação negativa entre sua intensidade e comprimento padrão do hospedeiro. Houve correlação positiva significativa entre a prevalência de Contracaecum Tipo 1 e o comprimento padrão dos hospedeirosFifty-one specimens of Acestrorhynchus lacustris (Lütken, 1875) collected on the Upper Paraná River floodplain were analyzed from February 2000 to November 2001. Of these, 35 (68.6%) were parasitized by at least one species of endohelminth. Eight species of endoparasites were found: five nematodes (Contracaecum Type 1 larvae of Moravec, Kohn and Fernades, 1993, Contracaecum Type 2 larvae of Moravec, Kohn and Fernades, 1993, Contracaecum sp., Eustrongylides sp. and Procamallanus sp.), two digeneans (Clinostomum sp. and Rhipidocotyle gibsoni Kohn and Fernandes, 1994) and one acanthocephalan (Quadrigyrus torquatus Van Cleave, 1920). Contracaecum sp. and Q. torquatus were positively associated and also had positively correlated abundances. There was significant difference in the prevalence and abudance of infection of Q. torquatus between hosts sexes. This parasite also presented negative correlation between its intensity and host standard length. There are significant positive correlation between the prevalence of Contracaecum Type 1 and host standard length Date A point or period of time associated with an event in the lifecycle of the resource 2003 Subject The topic of the resource Acestrorhynchus lacustris, Río Paraná, ecología, endoparasitas Identifier An unambiguous reference to the resource within a given context 10.4025/actascibiolsci.v25i2.2043 Source A related resource from which the described resource is derived Acta Scientiarum : Biological Sciences Publisher An entity responsible for making the resource available Universidade Estadual de Maringá Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant Biology (General), Microbiology Relation A related resource <a href="http://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/2043" target="_blank" rel="noreferrer noopener">http://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/2043</a>
