Resumo: | This work, which is part of a study program on meroplankton larvae, aims to gain more in-depth knowledge about planktonic larvae. This study began with the mollusk Brachidontes solisianus (Bivalvia - Mytilidae), which is abundant on the rocky shores of the Cabo Frio region (state of Rio de Janeiro, Brazil). Brachidontes solisianus larvae were grown under controlled conditions for a period of 26 days and were fed with Isochrysis galbana and Tetraselmis chui. The temperature was kept at 26 °C and the saltiness at 28 . Images of the larvae were taken daily with a light camera and measured with a micrometric lens until settlement occurred. The average size of the first D-shaped veliger stage was 90 µm in length and 70 µm in height, while the size in the last stage before settlement (pediveliger) was 273 µm in length and 257 µm in height. The comparative study of the hinge system involved the most abundant intertidal species of the study area: Brachidontes solisianus and Perna perna. The B. solisianus species were found to have more visible denticles at the extremities of the provinculum, whereas the denticles of the P. perna species occur along the entire provinculum. |

Este estudo foi iniciado com a espécie Brachidontes solisianus (Bivalvia - Mytilidae) que é muito abundante nos costões rochosos da região de Cabo Frio. O desenvolvimento larvar foi realizado sob condições controladas durante 26 dias. A alimentação foi feita com Isochrysis galbana e Tetraselmis chui. A temperatura e a salinidade foram mantidas a 26° C e 28 , respectivamente. Diariamente, as larvas foram desenhadas em câmara clara e medidas com ocular micrométrica até a fixação. A primeira fase de véliger em forma de "D" ou Prodissoconcha I, mediu em média, 90 µm de comprimento por 70 µm de altura e a última, antes da fase de fixação (Pedivéliger), mediu 273 µm de comprimento e 257 µm de altura. No estudo comparativo das charneiras, duas espécies foram consideradas: Brachidontes solisianus e Perna perna. Observou-se que a espécie B. solisianus apresenta dentes mais evidentes nas extremidades do provinculum, enquanto na espécie P. perna aparecem ao longo de todo o provinculum.Em processamentoInstituto Internacional de EcologiaLarval development of Brachidontes solisianus (Bivalvia, Mytilidae): with notes on differences between its hinge system and that of the mollusk Perna pernaDesenvolvimento larvar de Brachidontes solisianus: com notas sobre as diferenças do seu sistema ligamentar quando comparado ao de Perna pernainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleprodissoconch morphologylarval growthhinge systemprodissonconchacrescimento larvarligamentoinfo:eu-repo/semantics/openAccessengreponame:Repositório Institucional da UnBinstname:Universidade de Brasília (UnB)instacron:UNBORIGINAL28983.pdfapplication/pdf2169400http://repositorio2.unb.br/jspui/bitstream/10482/26790/1/28983.pdf4abdedbfc129b1498d0c26c0a28f1118MD51open access10482/267902023-10-11 14:27:39.513open accessoai:repositorio2.unb.br:10482/26790Biblioteca Digital de Teses e DissertaçõesPUBhttps://repositorio.unb.br/oai/requestopendoar:2023-10-11T17:27:39Repositório Institucional da UnB - Universidade de Brasília (UnB)false |
