in five selected sites along the Aliakmon River was studied from January
2005 to December 2005 in Northern Greece. Soil and water chemical parameters
in these sites were also evaluated. A total of 75 taxa were recorded belonging
to 37 families and 53 genera. The majority of the macrophytes belonged
to coastal plants (76%), whereas the rest of the macrophytes belonged
to aquatic plants (24%). Species of the family Asteraceae were dominant
among coastal plants, whereas species of the family Potamogetonaceae were
dominant among aquatic plants. Soil samples from the site of Dam of Veria
had higher pH and electric conductivity (80-100 cm depth), whereas CaCO3
contents were significantly higher in soil samples from the area of P.
Prodromos (60-80 cm depth). Most physicochemical water parameters as well
as selected soil nutrients and major ionic components showed an increase
during the low charge period (fall) compared to with the high charge period
(spring), especially in parameters associated with agricultural activity.
Furthermore, there was an increase in most examined values moving towards
the delta of the river.]]>Alexiadis, K.L., 19672nd Edn.,APHA,198517th Edn.,Pages: 1268Pages: 1268Kavadas, D., 1956-19641956-1964Koumitzis, Th., C. Samara, D. Voutsa and G.
