Spatial and temporal variations of meiofaunal communities in Cienfuegos Bay, Cuba

ABSTRACT The community structure of meiofauna was studied in 16 subtidal sampling stations and in four months in Cienfuegos Bay, Cuba for describing their patterns of distribution, as well as their possible causes. Silt/clay (S/C) and organic matter (OM) contents in sediment were positively correlat...
