Features of the structural organization and biomorphology of dominant plant species of Holarctic seas’ coasts along the tidal gradient
Investigations of the population and biomorphology of dominant species Plantago maritima L. (fam. Plantaginaceae) and Triglochin maritima L. (fam. Juncaginaceae) along the tidal gradient of the coasts of the White Sea are presented. The western coast of the White Sea has been chosen as a sample of H...
