Recent benthic foraminiferal assemblages and their relationship to environmental variables on the shoreface and inner shelf off Valencia (western Mediterranean).

摘要: The environmental variables that determine the distributions of benthic foraminiferal assemblages on shoreface and inner shelf north Valencia province (Western Mediterranean) are identified. possible influence such as water depth, distance from shore, hydrodynamics, substrate type, carbonate content, organic matter content human activity is evaluated. Multivariate cluster-Q-type analysis redundancy (RDA) used to identify have greatest assemblage distribution. spatial distribution closely associated with depth substrate. diversity abundance foraminifera shells increase their conservation improves. most common species in study area Ammonia beccarii, Rosalina globularis, Buccella granulata, Planorbulina mediterranensis, Lobatula lobatula. presence wastewater has not polluted (absence anomalous shells). direction discharge plume a potential source nutrients for deep water.
