Depth and sediment granulometry effects on subtidal meiofaunal assemblages of the subtropical coast of Granada (Alboran Sea)

Hypotheses about relationships of meiofaunal assemblages to depth and sediment granulometry were tested. Samples were taken at 3 and 15 metres depth, in sediments classified according to grain size as ‘coarse’, ‘medium’ and ‘fine’. The meiofaunal community was analysed at a high taxonomic level. The...

Sumario:Hypotheses about relationships of meiofaunal assemblages to depth and sediment granulometry were tested. Samples were taken at 3 and 15 metres depth, in sediments classified according to grain size as ‘coarse’, ‘medium’ and ‘fine’. The meiofaunal community was analysed at a high taxonomic level. The most representative taxa were Nematoda, Copepoda, Polychaeta, Gastrotrichia, Ostracoda, Turbellaria, and nauplius larvae. At three metres depth diversity was lesser than at the deeper site. Moreover, multivariate analyses showed differences in meiofaunal assemblages according to depth. No significant differences related to the granulometry of the sediment were detected.
