description  The malacological fauna of the Agua Dulce/El Ermitaño lagoon estuarine system was characterized and its relation to some environmental parameters determined. Five samplings were carried out in January, August, October and December 1993, and February 1994. Biological, hydrological and sediment samples were taken at seven stations in each water body of the system, located on the northern coast of the state of Jalisco (Mexico). The values of some physical and chemical parameters were recorded and differences were found between both water bodies, mainly in regard to salinity, as an average value of 27 psu was obtained for Agua Dulce lagoon and of 2 psu for El Ermitaño estuary. The qualitative analysis of the sediments showed that the system is made up of four basic types: sandy silt, clayey silt, fine to medium sand and a small part of rocky substrate. The malacological fauna was composed of two classes, Gasteropoda and Bivalvia, the first being the one that presented a greater number of species; 6,782 live organisms and 18,508 dead organisms were collected, corresponding to 17 species of gastropods and 14 bivalves. Of the 31 species collected, only 9 were found alive and some appeared in both water bodies in spite of the salinity gradient recorded in the system. Groups of representative species were identified for four types of environments (marine, >25 psu; euryhaline, 10–18 psu; brackish, 5–10 psu; and freshwater, 0–5 psu). Finally, the most important species were the bivalves Tagelus longisinuatus and Mytella strigata, and the gastropods Rissoella excolpa and Bittium mexicanum, with the highest abundances of the cycle. Low diversity values were obtained (D = 1.5–1.8, Dmax = 2.5); however, they were within those recorded for tropical and subtropical coastal ecosystems.

Para esto se llevaron a cabo cinco muestreos durante los meses de enero, agosto, octubre y diciembre de 1993, así como febrero de 1994. Las muestras biológicas, hidrológicas y de sedimentos se tomaron en siete estaciones de muestreo en cada cuerpo de agua del sistema, que se localiza en la costa norte del Estado de Jalisco (México). Los valores de algunos parámetros fisicoquímicos fueron registrados y se encontraron diferencias entre los dos cuerpos de agua, sobre todo en lo que respecta a la salinidad, obteniendo para la laguna Agua Dulce un valor promedio de 27 ups y para el estero El Ermitaño un valor promedio de 2 ups. El análisis cualitativo de los sedimentos mostró que el sistema está compuesto por cuatro tipos básicos: limo arenoso, limo arcilloso, arena media a fina y una pequeña parte de sustrato rocoso. La fauna malacológica encontrada estuvo compuesta por dos clases, Gasteropoda y Bivalvia, siendo la primera la que presentó un mayor número de especies. Se recolectaron 6,782 organismos vivos y 18,508 muertos, los cuales correspondieron a 17 especies de gasterópodos y 14 de bivalvos. De las 31 especies encontradas, sólo 9 se recolectaron vivas, existiendo algunas que se presentaron en ambos cuerpos de agua a pesar del gradiente de salinidad que se registró en el sistema. Se encontraron grupos de especies representativos para cuatro tipos de ambientes (marino, >25 ups; eurihalino, 10 a 18 ups; salobre, 5 a 10 ups; y dulceacuícola, 0 a 5 ups). Por último, las especies más relevantes fueron los bivalvos Tagelus longisinuatus y Mytella strigata, y los gasterópodos Rissoella excolpa y Bittium mexicanum, las cuales presentaron las abundancias más altas del ciclo. Se presentaron valores bajos de diversidad (D = 1.5 a 1.8, Dmáx = 2.5); sin embargo, éstos se mantuvieron dentro de los registrados para ecosistemas costeros tropicales y subtropicales.Iniversidad Autónoma de Baja California2003-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/14710.7773/cm.v29i2.147Ciencias Marinas; Vol. 29 No. 2 (2003); 169-184Ciencias Marinas; Vol. 29 Núm. 2 (2003); 169-1842395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/147/123info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/1472024-08-22T17:01:28Z
