| Abstract: | Spatial patterns of nematode community structure from two geographically spaced intermediate. micro-tidal beaches (i.e. Mediterranean and Baltic) were investigated. Differences in the nematode assemblages were found to be significantly different and related to the morphodynamic characteristics of the studied zones (upper beach. swash/breakers and subtidal). Highest nematode densities and species diversities were recorded on the coarse-grained, more physically controlled. Italian beach in contrast to the more chemically controlled Polish beach. This is in contrast to the worldwide patterns of macrofaunal coinmunities. As demonstrated by higher taxonomic distinctness measurements, upper beaches were found to harbour species from both the marine and terrestrial ecosystem and are considered to be important ecotones between these adjacent systems. The swash/breaker zones are characterised by the loss of distinctive species caused by the high water percolation in these zones. The concept of parallel ecological communities 'isocommunities' is only supported for the upper beach zones. (C) 2004 Elsevier Ltd. All rights reserved. |
