Planktonic, epipelic and epiphytic algae were studied monthly, during the period from January to December 1985 in the Garmat ali river, a naturally regulated river draining to the al-Hammar marsh, Iraq. Chlorophyll-a, primary productivity and water
quality variables were also measured. High light penetration was noticed during the winter and spring. Seasonal variations were clear in the total cell numbers of algae from different habitats.

The Holocene palaeogeography of Paanajärvi National Park was studied by geobotanical, palaeobotanical, palynological, radiocarbon methods, and certain classes of organisms such as Algae, Fungi, Rhizopoda, Rotatoria. To increase the reliability
. It is shown that the former lake regime can be reconstructed by analysing the composition of the algae and other organisms.

Cyanobacteria (blue-green algae) have become an issue of increasing concern to water-resource managers in recent years. Cyanobacterial blooms form when a large population migrates to the lake surface. Vertical migration is controlled

Ephemeral sand ripples are described from steep sandstone rock surfaces in the south of England. They are unconsolidated or stabilized by algae and bryophytes. The sand is transported by flowing water to produce a semi-regular pattern of sinuous

The author collected phytoplankton in lake Abashiri during 1978 to 1979 and identified total 189 taxa of phytoplankton including Cyanophyceae, chrysophyceae, bacillariophyceae, and Chlorophyceae. Three periphytic algae were identified. This paper
