Imposex en Plicopurpura pansa (Neogastropoda: Thaididae) en Nayarit y Sinaloa, México

Abstract

"Imposex is the development of male features in female prosobranch gastropods, caused by organotin compounds. In the Mexican Pacific coast, imposex was observed in Plicopurpura pansa . This snail has been used by indigenous people to dye cotton and traditional fabric clothing. During 2010 and 2011, 5 habitats were visited along the coastline of Nayarit and Sinaloa, Mexico. At low tide, 675 snails were collected. Shell length, sex ratio and imposex incidence were measured. Imposex incidences were higher in the samples collected near harbor areas.""El imposex es el desarrollo de características masculinas en hembras de gasterópodos prosobranquios, causado por compuestos organoestañosos. En la costa del Pacífico mexicano se observó el imposex en el caracol Plicopurpura pansa . Este caracol ha sido utilizado por grupos indígenas para teñir algodón y fabricar su ropa tradicional. Durante 2010 y 2011, se visitaron 5 hábitats en la costa de Nayarit y Sinaloa, México. Se recolectaron 675 caracoles durante la marea baja; se midió la longitud de la concha, proporción de sexos y la incidencia de imposex. De acuerdo con los resultados, la incidencia de imposex fue más alta en las muestras recolectadas en las áreas cercanas a los muelles.
