“…Bivalve mollusks are among the models that have been used to study the correlation between genetic and morphological variation and different factors like localities, environments, and time (Laudien et al 2003, Kong et al 2007, Zieritz et al 2010, Inoue et al 2013, Begum et al 2018, Bonner et al 2019. Bivalve mollusks have a wide geographic distribution, occupy a relatively wide range of environmental conditions, and are relatively abundant (Simpson & Harnik 2009, Lorion et al 2010, besides being animals of commercial importance for coastal communities (Krause et al 2019, Olivier et al 2020.…”

“…Anomalocardia brasiliana is an exclusively Brazilian species that has been studied since the 1970s in different approaches (Narchi 1972b, Mouëza et al 1999, Arruda et al 2009, Silva-Cavalcanti & Costa 2011, Corte et al 2017, similar to the species Crassostrea rhizophorae (Martino & Cruz 2004, Freitas et al 2006, Leal et al 2008, Kanhai et al 2014. However, I. brasiliensis is poorly studied despite its commercial relevance (Narchi 1972a, Ceuta et al 2010, Bonner et al 2019.…”

Iphigenia brasiliensis is a bivalve mollusk exploited as a shellfish and subsistence resource on the Brazilian coast, mainly in the north and northeast regions. Genetic (allozyme electrophoresis revealed eight gene loci) and morphological variations (multivariate morphometry of valves used 13 linear measurements of traditional and 19 Fourier coefficients of geometric morphometry) were studied, considering the geographic (445 km of the southwest tropical Atlantic), environmental (mangroves and channels of communication with the sea of three estuaries in the state of Rio de Janeiro), and temporal dimensions (over two years). I. brasiliensis showed high levels of genetic variation (the average number of alleles per locus ranged from 2.8 to 3.4, and the average heterozygosity ranged from 0.441 to 0.675). Bayesian analysis of population partitioning showed that the highest LnP(D) value was achieved for K = 3. These results indicated mixed ancestry, possibly oscillations in the dispersion dynamics among the different sampling groups, and temporal oscillations in the population sizes due to the anthropogenic influence on the studied estuaries. The results of morphological variation, inferred by the PERMANOVA from the Fourier analysis, indicated that a similar influence might occur in valves (also, the discriminant analysis showed that different groups could be consistently identified). In this sense, the studied populations may be organized in a dynamic of metapopulations. Finally, these are the first data on morphological and genetic variation of the species in the latitudinal, environmental, and temporal dimensions studied simultaneously, thus providing relevant information for the exploration, management, and conservation of this commercially important species.

“…Mesmo apresentando importância socioeconômica ao longo da costa brasileira (com destaque aos estados de Pernambuco, Bahia e Rio de Janeiro) (Arruda et al 2019;Ferreira et al 2019), poucos estudos são realizados com I. brasiliensis. Algumas das pesquisas efetuadas com a espécie são: descrição dos parâmetros morfofuncionais (Narchi 1972), gametogênese (Mesquita et al 2001;Silva et al 2012), comportamento reprodutivo (Silva et al 2012, casos de hermafroditismo (Ceuta et al 2010), biometria e proporção sexual (Silva et al 2016) e variação genética e assimetria entre populações (Bonner et al 2019). Destaca-se também a revisão efetuada por Ferreira et al (2019), que realizou uma revisão sistemática da bibliografia produzida a respeito de I. brasiliensis listando outros trabalhos encontrados sobre a espécie.…”

Iphigenia brasiliensis (Lamarck, 1818) é um molusco bivalve marinho pertencente à família Donacidae, que se distribui desde o Golfo do México até o sul da costa brasileira. Habita a região intermareal, onde é coletada por marisqueiras para alimentação e comércio. O presente estudo tem o objetivo de caracterizar a biometria e o crescimento relativo de I. brasiliensis, coletado em um banco natural, situado na Baía do Caeté, litoral amazônico. Para tanto, mensurou-se as medidas morfométricas e determinou-se a biomassa úmida dos moluscos coletados. Posteriormente, determinou-se a correlação das variáveis e efetuaram-se relações biomorfométricas. Adicionalmente, o crescimento relativo entre as variáveis foi analisado por meio do coeficiente de alometria. Testou-se também se há relação entre as razões morfométricas da concha e a biomassa úmida dos indivíduos. Os resultados indicam que I. brasiliensis apresenta medidas morfométricas altamente correlacionadas, não sendo evidenciado diferenças significativas no tamanho dos indivíduos por período sazonal. Destacam-se as relações entre as medidas do comprimento anteroposterior e a altura, ambas com a biomassa úmida, como isométrica, o que indica crescimento proporcional entre essas variáveis. Além dos resultados obtidos, recomendamos estudos acerca da biologia reprodutiva e sugerimos estudos de crescimento utilizando marcadores internos para estimar o crescimento absoluto da espécie.Palavras chave: Região Amazônica, molusco bivalve, morfometria.
