Resumo: | Hypostomus ancistroides (Ihering, 1911) is a widely distributed species in the upper Paraná river basin and is also one of the most abundant species of this hydrographic region. Considering the premise that isolated populations in environments with distinct environmental characteristics may be influenced by intrinsic abiotic and biotic factors of the site, which culminate in the selection of certain adaptive attributes of an ecological character, we have tested the hypothesis that populations of H. ancistroides resident in different basins present differences in ecomorphological attributes. A total of 150 individuals of H. ancistroides from 10 different basins were analyzed within the upper Paraná River system. Fifteen specimens of H. ancistroides from each population were used to test the differences. Twenty-six morphometric measures were taken and six areas were calculated, so that 22 ecomorphological indices were calculated. In order to demonstrate ecomorphological differences between the specimens, we performed Canonical Variate Analysis (CVA) and a post hoc test of paired comparisons of Hotelling. All comparative relationships among populations showed significant differences. The factors that influenced the population variations were credited to the hydrodynamic differences in the longitudinal dimension of the rivers provided, mainly, by cascade of reservoirs and their consequences.Keywords: Cascade of reservoirs; dams; Ivaí River; morphology; Paranapanema River. |

Considerando a premissa de que populações isoladas em ambientes com características ambientais distintas podem ser influenciados por fatores abióticos e bióticos intrínsecos do local, os quais culminam na seleção de certos atributos adaptativos de caráter ecológico, foi testada a hipótese de que populações de H. ancistroides residentes em diferentes bacias hidrográficas apresentam diferenças nos atributos ecomorfológicos. Foram analisados 150 indivíduos de H. ancistroides provenientes de 10 bacias diferentes dentro do sistema do alto rio Paraná. Para testar as diferenças foram utilizados 15 exemplares de H. ancistroides de cada população, sendo tomadas 26 medidas morfométricas e calculadas seis áreas, de maneira que foram calculados 22 índices ecomorfológicos. Para evidenciar diferenças ecomorfológicas entre os espécimes foram realizados Análises de Variáveis Canônicas (AVC) e um teste “post hoc” de comparações pareadas de Hotelling. Todas as relações comparativas entre as populações apresentaram diferenças significativas. Os fatores que influenciaram as variações populacionais foram creditados às diferenças hidrodinâmicas na dimensão longitudinal dos rios providas, principalmente, por represamentos em cascata e suas consequências.Palavras-chave: Barramentos, cascata de reservatórios, morfologia, rio Ivaí, rio Paranapanema.Universidade Federal do AmapáCAPESCNPqde Souza, FagnerAltoé, Guilherme Guerinoda Silva Camargo, Paulo Ricardoda Silva, Roenilson GaiaFrota, Augusto2023-06-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/665510.18561/2179-5746/biotaamazonia.v13n1p30-35Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 13, n. 1 (2023); 30-352179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/6655/v13n1p30-35.pdfhttps://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/6655/1155Direitos autorais 2023 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2023-12-31T14:31:54Zoai:ojs.pkp.sfu.ca:article/6655Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2023-12-31T14:31:54Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false |
