| Sumario: | The distributional patterns and related environmental parameters for four species of benthic foraminifera of the Superfamily Planorbulinacea occurring in surface sediments from the northeast Gulf of Cadiz are discussed. Their distribution is related to bathymetry, in the case of Hyalinea balthica (Schröter, 1783), and to the texture of the sediments in the area for the other three, Cibicides refulgens (Montfort, 1808), Lobatula lobatula (Walter and Jacob, 1798) and Planorbulina mediterranensis (d´Orbigny 1826). Two characteristic assemblages were differentiated with Q-mode analysis: F1 (H. balthica), affected mainly by water depth; and F2 (C. refulgens and L. lobatula), related to the substrate, typical of high-energy/low sedimentation rate environments. |
