Seasonal shifts of meiofauna community structures on sandy beaches along the Chennai coast, India

Seasonal shifts of meiofauna community structures on sandy beaches along the Chennai coast, India INTRODUCTION Meiofauna represents the smaller-sized component of the benthos and provides the food for higher consumer levels (Coull et al., 1995; Dahms et al., 2006). Meiofauna production can be equal to or higher than that of macrofauna (Warwick et al., 1979). Meiofauna enhances nutrient mineralization (Montagna, 1995; Fenchel, 1996) and affects biogeochemical cycles (Aller & Aller, 1992; Murray et al., 2002). Meiofauna taxa exhibit high sensitivity to various kinds of disturbance of anthropogenic nature, that make them useful bioindicators for the state of environmental health (Coull & Chandler, 1992; Chandler & Green, 2001; Dahms & Hellio, 2009). Sandy beaches are very much understudied with respect to meiofauna (McLachlan & Brown, 2006). Sandy beaches provide important environments in coastal ecosystems of both tropical and temperate regions, showing a remarkable biodiversity (McLachlan & Brown, 2006), and providing a dynamic environment with variations related to natural abiotic characteristics such as temperature, salinity, desiccation, mean grain size of sediment, sea bottom currents (Coull & Bell, 1979; McLachlan et al., 1996; Coull, 1999; Corgosinho et al., 2003), and community changes that might be mediated by biotic interactions like competition and predation (Snelgrove & Butman, 1994).

Abstract

INTRODUCTION Meiofauna represents the smaller-sized component of the benthos and provides the food for higher consumer levels (Coull et al., 1995; Dahms et al., 2006). Meiofauna production can be equal to or higher than that of macrofauna (Warwick et al., 1979). Meiofauna enhances nutrient mineralization (Montagna, 1995; Fenchel, 1996) and affects biogeochemical cycles (Aller & Aller, 1992; Murray et al., 2002). Meiofauna taxa exhibit high sensitivity to various kinds of disturbance of anthropogenic nature, that make them useful bioindicators for the state of environmental health (Coull & Chandler, 1992; Chandler & Green, 2001; Dahms & Hellio, 2009). Sandy beaches are very much understudied with respect to meiofauna (McLachlan & Brown, 2006). Sandy beaches provide important environments in coastal ecosystems of both tropical and temperate regions, showing a remarkable biodiversity (McLachlan & Brown, 2006), and providing a dynamic environment with variations related to natural abiotic characteristics such as temperature, salinity, desiccation, mean grain size of sediment, sea bottom currents (Coull & Bell, 1979; McLachlan et al., 1996; Coull, 1999; Corgosinho et al., 2003), and community changes that might be mediated by biotic interactions like competition and predation (Snelgrove & Butman, 1994).
