“…Changes in water and sediment quality subsequently lead to changes in the macrophyte community composition and vice versa [9,40,55]. High light penetration and high water transparency can be the result of low phytoplankton densities (as indicated by low Chl-a concentrations) but can also be promoted by the distribution of macrophyte assemblages as the dominance of angiosperms that diminishes the resuspension of the sediments [56].…”

“…This type includes Tsoukalio and Logarou lagoons (Amvarkikos Gulf) and Kleisova lagoon that belongs to the lagoonal complex system of Messolonghi-Aitoliko; (c) Type III includes small, shallow and restricted lagoons with euhaline salinity regime and medium seawater intrusion (Araxos lagoon). Detailed information is reported in Christia and Papastergiadou [2] and Christia et al [9,35]. According to Christia et al [9] the typological classification of lagoons also revealed a fourth type which includes Kaiafas but this has been omitted from the current research due to its peculiar environmental characteristics: small, deep, mesohaline lagoon with a wide barrier and a unique macrophyte assemblage composed by Potamogeton pectinatus and Chara hispida f. corfuensis.…”

“…The current study was based on the typological framework of coastal lagoons of Western Greece (Ionian Sea), as derived by Christia et al [9]. According to them, the investigated area is classified into three different lagoon types based on hydromorphological characteristics ( Figure 1): (a) Lagoon Type I includes large, chocked lagoons with meso to polyhaline waters as Rodia which belongs to the natural complex system of Amvrakikos Gulf; (b) Type II consists of large, shallow, restricted lagoons with poly to euhaline salinity regimes and higher sea water exchanges.…”

Coastal lagoon types of Western Greece were allocated to a spectrum of meso to polyhaline chocked lagoons; poly to euhaline restricted lagoons; and euhaline restricted lagoons along the Ionian Sea coast. This diversity comprises wide ranges of physical, chemical and environmental parameters in a seasonal and annual scale, which explains the variability in the distribution of benthic macrophytes. Four different macrophyte assemblages were distinguished, characterized by annual or perennial species. Extensive statistical analysis showed that salinity and nitrate concentrations had a great impact on the composition and distribution of macrophyte assemblages into lagoon types that also changed their abundance on a seasonal and annual scale. During the monitoring period, an important salinity shift in a chocked lagoon might cause the gradual loss of Zostera noltii and its replacement by Ruppia cirrhosa. Restricted lagoons were characterized by higher species diversity, while the other three identified macrophyte assemblages were dominated by the angiosperms Ruppia cirrhosa and Cymodocea nodosa. This integrated study of coastal lagoons is likely to be broadly applicable, since it was based on important parameters affecting such ecosystems, and the provided links between macrophyte assemblages and abiotic factors are of critical importance to improve management and environmental policies.
