This research deals with comparable study of the specific composition of assemblages
gastropoda and migratory species in four regions of Syrian coast, which differed by substrate
nature and their exposure to pollution resources and rivers estuaries
, They are as fallow:The
Southern Region of Lattakia, AL Bhyss and AL Moelh South of Jableh, Estuary Assin. This
research was done between April 2010 and April 2011. The samples were collected from the
supralittoral ,littoral and sublittoral regions at depth 3m.
This study was conducted to evaluation of some marshes soil physical
characteristics at south Iraq from studying soil properties and accounting the
simple and multiple correlation coefficients and relation equations, from which
we can predicted th
e soil aggregate stability modules of rapture and soil bulk
density. Three transacts were chosen, which cover all south Iraqi marshes, with
selection of the larger marshes at every transect. The transects are: First
toward Amara included marshes of Al-Msendak, Al-Saadiah and Al-Wadiah.
Second toward Al- Nasiriah which included the marshes of Delmag, Ghumugaa
and Al-hammar. Third toward Samawa which included the marshes of Al-
