Indicadores bioticos y fraccion de tamanos en la definicion de la macrofauna

Abstract: RESUMEN. El tamaño de la abertura de malla en tamices para retener macrofauna bentónica, podría afectar la estimación de los indicadores bióticos que describen el estado del sistema béntico submareal. El objetivo de este estudio fue determinar el efecto que tendría el límite inferior de abertura de la malla en las estimaciones de indicadores bióticos en dos centros de cultivo de mitílidos en el Seno de Reloncaví, Puerto Montt, Chile. Los datos fueron colectados desde muestras de sedimento obtenidas en estacion… Show more

“…The sediment samples obtained for macrofauna analysis were sieved in the laboratory with a 500-μm sieve [38,39]. The sieved material was placed in plastic flasks and preserved in 96% ethanol.…”

“…En Chile, Pino et al (2015) evaluaron el uso de dos aberturas de trama de tamices para la caracterización de la macrofauna bentónica al suroeste del Seno de Reloncaví. Este estudio, basado en muestras cercanas y lejanas a dos centros de cultivo de mitílidos, reporta que, de manera similar a lo registrado por el nuestro, el uso de un tamiz de 500 µm aumenta la abundancia de especies/taxa oportunistas, en comparación a uno de 1.000 µm.…”

“…Furthermore, the size, abundance, frequency, and the consistence appearance of Polygordius exolarvae makes them good candidates for biological trackers (Levin, 1990) of environmental fluctuations in circulatory patterns (Cañete et al 2016), oceanographic process (Mann & Lazier, 1991;Garçon et al 2001), temperature gradients (Valle-Levinson et al 2006), salinity (Johan et al 2012), organic enrichment of sediments from aquaculture (Pino et al 2015), and the productivity along southern Region, Chile (CIMAR 16). a) Anterior end, with primordial palps, one ocellus, and the ciliary band of the prototroch; b) posterior end of pygidium, showing the telotroch band; c) a complete, preserved neustonic individual (type "banana larvae").…”

“…Indeed, several studies of pelagic communities in the Strait of Magellan and the Beagle Channel (Marín & Antezana, 1985;Mazzocchi et al 1995;Hamamé & Antezana, 1999;Marín & Delgado, 2001) make no reference to the presence of Polygordius larvae (Biancalana et al 2007;Aguirre et al 2012). However, some benthic studies in the southern Chile demonstrate of abundant population in sedimentary intertidal flat of estuarine system from southern Chile (Acuña et al 2012;Pino et al 2015).…”
