Benthic macrofauna of three saline-lake wetlands on the coastal rim of southern Chile

 A coastal-lake wetland is a type of inland water ecosystem that does not occur very frequently in Chile, of which lakes Budi, Huillinco and Cucao are examples. Textural differences were found in the various constituent parts of the coastal lake sediments. Gravel was the smallest fraction a...

Textural differences were found in the various constituent parts of the coastal lake sediments. Gravel was the smallest fraction and showed significant differences among the three coastal lakes (P < 0.05). Significant differences (P < 0.05) were also recorded for the sand and mud fractions. Lakes Cucao and Huillinco are described as muddy sand, in contrast to Lake Budi, which is described as sandy mud, composed primarily of mud with a smaller percentage of sand. There were statistical differences among the lakes with regard to the contributions of organic matter in each fraction. The macrofauna in these bodies of water belongs to the fauna inhabiting estuary environments in southern Chile. Lake Budi had seven taxa, and lakes Huillinco and Cucao ten species of macrofauna each. There were no significant differences in the number of species captured at the three coastal lakes (P > 0.05), but differences did emerge in comparisons made among the sampling stations. Total abundances showed significant differences (P < 0.05) in comparisons made both among the lakes and the stations. Salinity and grain size could be limiting the density and number of species at the lakes.Un lago costero es un tipo de ecosistema de agua interior que no se encuentra muy frecuentemente en Chile; los lagos Budi, Huillinco y Cucao son ejemplos de este tipo de ecosistemas. Se encontraron diferencias texturales en los sedimentos de estos lagos costeros. La grava constituyó el porcentaje más pequeño, con diferencias significativas entre los tres lagos (P < 0.05). Los porcentajes de arena y de fango también presentaron diferencias significativas (P < 0.05). Los lagos Cucao y Huillinco se describen como de arena fangosa, en contraste con el Lago Budi que se describe como fango arenoso, compuesto principalmente de fango con un menor porcentaje de arena. Se encontraron diferencias estadísticas entre los lagos con respecto a las contribuciones de la materia orgánica a cada una de las fracciones. La macrofauna presente en estos cuerpos de agua pertenece a la fauna que habita en ambientes estuarinos en el sur de Chile. El Lago Budi presentó siete taxa y los lagos Huillinco y Cucao diez especies de macrofauna cada uno. No hubo ninguna diferencia significativa entre el número de especies capturadas en los tres lagos costeros (P > 0.05), pero sí surgieron diferencias al comparar entre estaciones. Las abundancias totales presentaron diferencias significativas (P < 0.05) en las comparaciones hechas entre los lagos y entre las estaciones. La salinidad y el tamaño del sedimento podrían estar limitando la densidad y el número de especies en estos lagosIniversidad Autónoma de Baja California2006-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed research noteNota de investigación arbitradaapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/112010.7773/cm.v32i3.1120Ciencias Marinas; Vol. 32 No. 3 (2006); 589-596Ciencias Marinas; Vol. 32 Núm. 3 (2006); 589-5962395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1120/1914info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/11202024-08-22T17:01:38Z

description  A coastal-lake wetland is a type of inland water ecosystem that does not occur very frequently in Chile, of which lakes Budi, Huillinco and Cucao are examples. Textural differences were found in the various constituent parts of the coastal lake sediments. Gravel was the smallest fraction and showed significant differences among the three coastal lakes (P < 0.05). Significant differences (P < 0.05) were also recorded for the sand and mud fractions. Lakes Cucao and Huillinco are described as muddy sand, in contrast to Lake Budi, which is described as sandy mud, composed primarily of mud with a smaller percentage of sand. There were statistical differences among the lakes with regard to the contributions of organic matter in each fraction. The macrofauna in these bodies of water belongs to the fauna inhabiting estuary environments in southern Chile. Lake Budi had seven taxa, and lakes Huillinco and Cucao ten species of macrofauna each. There were no significant differences in the number of species captured at the three coastal lakes (P > 0.05), but differences did emerge in comparisons made among the sampling stations. Total abundances showed significant differences (P < 0.05) in comparisons made both among the lakes and the stations. Salinity and grain size could be limiting the density and number of species at the lakes.
