contents Size composition and sex ratio of Anadara tuberculosa and Anadara similis in a mangrove reserve from the northwest of Ecuador Luis Flores Roberto Licandeo Ciencias de la Tierra Shell length natural beds mangrove cockles Shell length frequency distribution (SLFD) and sex ratio of a subpopulation of the mangrove cockles Anadara tuberculosa and Anadara similis were analyzed from natural beds in the Cayapas-Mataje Ecological Mangrove Reserve, Ecuador. The SLFD was different between sexes for both species; females were larger than males. Subpopulations of A. tuberculosa and A. similis were dominated by females throughout the year. The overall sex ratio was 2.6:1 (female: male), although with variations in the monthly samples, from 1.2:1 to 5.9:1 in A. tuberculosa and 1.9:1 to 5.3:1 in A. similis. Possibly, these results may be due to differential growth rate between sexes and environmental factors along the year. 2010 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47919217021 http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.3 Vol.45
