“…High nutrient content in the tissues of European native and Far Eastern populations agree with their high invasive potential indicated by their vigorous growth, and also with the invasion success of European clones in North America (Meyerson et al 2009). The leaf-nitrogen values in our experiment were close to the maxima found in plants cultivated under high supply of nutrients (Clevering 1998) and to the maxima found in the field (Kohl et al 1998, Farnsworth & Meyerson 2003, Baldantoni et al 2004, Soetaert et al 2004, Elvisto 2010. The pattern of the highest leaf-nitrogen values in European clones followed by North American invasive and North American native genotypes (Guo et al 2014) was confirmed in our experiment.…”

“…Also the leaf-carbon values were close to maxima of 455-465 mg·g -1 reported from the field for European (Csatari et al 2015) and North American invasive plants (Schaefer et al 2014). The leaf phosphorus was comparable with the values, including maxima of 2.5-2.9 mg·g -1 , reported from the field in Europe (Baldantoni et al 2004, Elvisto 2010, Flury & Gessner 2014, Marchand et al 2014.…”

Meyerson L. A. (2019) Physiology of a plant invasion: biomass production, growth and tissue chemistry of invasive and native Phragmites australis populations. -Preslia 91: 51-75.Differentiation within Phragmites australis, one of the world's most cosmopolitan and globally important wild plants, and invasions by individual lineages outside of their native ranges is attracting the interest of scientists worldwide. We compared the physiological performance of 89 populations representing distinct genotypes from six phylogeographic groups from Australia, Europe, North America (two groups including native and invasive populations introduced from Europe), South Africa and Far East in a common garden experiment. We show that the populations cluster into two distinct groups: one that includes populations from Europe and Far East together with the North American invasive, and the second the North American native populations with those from Australia and South Africa. Populations within the former group exhibited superior performance in the following traits: they were more vigorous in terms of higher shoot number per pot, greater belowground biomass, longer rhizomes, had greater specific leaf area (SLA), higher N and P concentrations in tissues, and greater investment into generative reproduction. Pooled across phylogeographic groups, P. australis has higher values of maximal photosynthesis (Amax), higher N and P concentrations in tissues, and greater SLA than most vascular plants, represented by the GLOPNET dataset. Whether due to a weak environmental match or genetic differences, the results indicate that invasion by Australian and African populations in the Northern Hemisphere seems unlikely at present. However, it is not possible to exclude the invasion of genotypes of European origin into Southern Hemisphere or other temperate regions. K e y w o r d s: below-and aboveground biomass,

“…Previous studies also reported high efficiency of reed to remove nutrients (Álvarez-Rogel et al, 2006;Zhao et al, 2012), as well as heavy metals (Weis and Weis, 2004), from wetland soils. Foliar P concentrations in PC were much similar to those observed in PA, probably because a higher fraction of P was recycled from below ground tissues in PC compared with PA. Conversely, P concentrations in reed leaves in SM were several times lower than those usually recorded at nutrient-rich sites (see, for example: Ho, 1981;Elvisto, 2010;Ruiz and Velasco, 2010). Such low P concentrations in reed leaves in SM resulted in very high N : P ratios, suggesting that P limits reed growth in this community (Koerselman and Meuleman, 1996).…”

Reed (Phragmites australis) is widespread in aquatic habitats in Europe where it plays an important ecological role, especially as stabilizer of lake and river shores and as filter against pollutants. Reed is also abundant in ecotones towards terrestrial habitats, especially fen meadows, where its expansion can out-compete rare slowly-growing fen species. Therefore, defining appropriate guidelines for managing reed in wetlands has to consider differences in the ecological roles that reed plays in different wetland habitats. In a small pre-alpine lake in N Italy, we mowed reed stands in three plant communities located along a transect from the lake shore to the periphery. In each community, three areas were subjected to reed mowing in late winter, as traditionally done in the past. Three additional areas were subjected to mowing in winter and summer, while three areas served as un-treated controls. Summer mowing was carried out in August, when the nesting period of birds was concluded. Mowing in winter did not affect reed aboveground biomass (RAB) in any community but enhanced the efficiency of removing nutrients by reducing litter accumulation in the soil. Mowing in winter and summer only slightly decreased RAB in the riparian community, not at all in the intermediate community but significantly diminished RAB in fen meadows. Phosphorus deficiency and/or reduced competition with other species probably accounted for RAB reduction in fen meadows. In conclusion, winter mowing can be overall recommended for preventing eutrophication of littoral habitats while summer mowing is advisable for preventing reed expansion in fen meadows. However, the timing of summer mowing has to be defined considering all requirements needed for optimal management of each individual site.

“…The third study site (Paljassaare) is in the eastern part of the Saartevahe Haak, a small bay at the tip of the Paljassaare peninsula in the Tallinn area on the Gulf of Finland. Overgrown with reed beds, it is a sandy beach zone with a marine sand layer, resulting from accumulating wave activity, which sits on till layers (Elvisto 2010). This site is not managed.…”

Main Driving Factors for Seacoast Vegetation in the Southern and Eastern Baltic

This study aimed to determine the role of environmental factors in the pattern of vegetation related to marsh soils, which are rare in the Baltic coastal zone. It was assumed that the pattern of vegetation directly affected by seawater depends on seawater salinity, and in general reflects the decreasing salinity gradient of the Baltic Sea. The research of vegetation and soils (0-25 cm) has been undertaken on 11 selected sites along the Baltic seacoast in Germany, Poland and Estonia. According to TWINSPAN classification, five plant communities were distinguished: the Puccinellia maritima-Spergularia marina community, Juncus gerardi community, Agrostis stolonifera-Phragmites australisScirpus lacustris ssp. tabernaemontani community, Phragmites australis-Calystegia sepium community and Elymus repens community. A canonical correspondence analysis showed that the most important environmental factors influencing vegetation differentiation were: electrical conductivity of the saturation paste extract, hay/pasture management, redox potential, soil moisture and actual pH. In conclusion, the spatial distribution of the investigated vegetation and soil properties along the Baltic Sea shore were inconsistent with the spatial salinity gradient of the open surface seawater, but was significantly dependent on local conditions. This was confirmed by the highest soil salinity and most abundant occurrence of Salicornia europaea in Estonia.
