- W55880345 abstract "Amvrakikos Gulf, situated in Western Greece, is one of the most important areas of the country, protected by the Ramsar Convention, especially for waterfowl populations, and recently has been included to the Natura 2000 Network with code number GR2110001. It is considered to be a very important biotope for flora and fauna and especially for birds that they are nesting and breeding in such type of habitats. The lagoons of Amvrakikos Gulf appear mainly at the north part of it. The most important lagoons are Rodia, Tsoukalio and Ayleri western of Salaora’ s hill and Logarou at the eastern part of the same hill. Two of the lagoons are interconnected and separated from the third by a narrow strip of land. Coastal lagoons, situated between the land and the sea, are influenced by both marine and terrestrial factors and subjected to increased nutrient inputs by rivers and human activities of the catchment area. Coastal lagoons are autonomous dynamic systems with a high productivity potential and a number of common morphological and ecological features. Characteristic features of these systems are frequent fluctuations in the environmental parameters (temperature and salinity) causing severe changes in the abundance and distribution of organisms. The ecological study is based on monitoring data on the seasonal variation during the vegetated periods of 2003-‘04 on submerged vegetation, nutrients, light and physicochemical parameters of water (depth, transparency, temperature, salinity, conductivity, dissolved oxygen, pH), in three shallow coastal brackish lagoons of Amvrakikos Gulf, Ionian Sea. It was studied the species composition, the seasonal variations and the succession of submerged macrophytes in relation to the main environmental factors and the abundance of the different species. The submerged flora in the Rodia and Tsoukalio is dominated by a charophytes, Lamprothamnium papulosum and an important angiosperm Zostera noltii. In Logarou two species of macroalgae Gracilaria-bursa pastoris and Acetabularia mediterranea, are abundant while Zostera noltii occurs with a limited presence. Statistical analyses and ordination methods were performed with statistical package SPSS (V. 12) and PC Ord (V.4). The hydrological regime, depth, water transparency and the fluctuation of salinity seems to be the main factors controlling the abundance of different species in three lagoons. When the salinity changed during the second year of the survey it was observed an alteration of the vegetation. The most important alteration happened at Rodia lagoon on spring 2004. It was also observed changes on the concentrations of nutrients and especially on nitrogen. The concentrations of nitrates were higher in spring and autumn due to inputs from catchments area. On autumn they were observed higher concentrations of ammonium with the exception of phosphates that they were very low something that recorded in similar ecosystems in other areas of the world." @default.
