SUMMARY:Spatial homogeneity of seagrass faunal biodiversity - Pr. Richard

DESCRIPTION:The benthic animal species inhabiting seagrass meadows at site
 s in warm-temperate South Africa\, subtropical Queensland and the cool-tem
 perate North Sea all show heterogeneous (= patchy) distributions and accor
 dingly the assemblages that they form vary widely in composition across ea
 ch site.  Nevertheless\, at each site the number of species per unit area 
 ('species density') is statistically homogeneous (= uniform) over large ar
 eas (up to 6+ km)\, as is species richness and ENS diversity:  something s
 eemingly unreported from other systems.  Further the number of species per
  sample is effectively the same at all three disparate sites.  Is this ext
 reme deterministic control of assemblage structure?  The reasons for these
  peculiar ecological conditions are described in this talk.
