“…Regarding European coastal dunes, most studies have examined several functional traits at species level to explore plant adaptation to environmental factors (García-Mora et al, 1999;Acosta et al, 2006;Ciccarelli et al, 2009Ciccarelli et al, , 2010Gratani et al, 2009;Bermúdez & Retuerto, 2013, 2014Spanò et al, 2013); others have studied functional traits at community level analysing the relationship between functional diversity and phylogenetic structure of plant communities (Ricotta et al, 2012;Carboni et al, 2013;Brunbjerg et al, 2014); few studies have analysed coastal dune vegetation adopting Grime's (1974Grime's ( , 2001) CSR (Competition, Stress-tolerance, and Ruderality) strategy scheme (Macedo et al, 2010;Brunbjerg et al, 2012).…”

“…the proportion of absorbed light that is actually used in PSII photochemistry; 2) the maximum PSII quantum yield (Fv/Fm) of dark-adapted leaves, which is one of the most common indicators of stress in plants (Murchie and Lawson, 2013). Abiotic stress factors of coastal environments can induce oxidative stress in plants (Spanò et al, 2013) and hydrogen peroxide content was determined as a marker of stress level. Phenols, important antioxidant protective molecules, were also measured to test antioxidant defense response.…”

Coastal dune environment, due to the complex coast-to-inland gradient, contributes greatly to plant biodiversity. The ability of plants to withstand the harsh conditions of this habitat leads to a peculiar vegetation profile which may be affected by the natural and artificial degradation of the coast. Given that these disturbances are bound to increase in the future, there is a great interest in the deepening of knowledge of resistance mechanisms allowing plants to colonize this stressful environment. Our focus was on physiological stress markers that could be early signals of changes before ecological disturbances become evident. Three representative species of the different dune zones, Achillea maritima, Ammophila arenaria and Helichrysum stoechas were studied during the four seasons. Winter and summer were confirmed as the most critical seasons with different levels of stress depending on the coast profile where plants grew. The shoreline-inland gradient of stress conditions was evident only for A. arenaria, whose physiology was negatively affected in foredune during summer and for this reason this species could be a useful indicator of increasingly harsh environmental conditions. Physiological performances of the studied species changed across the seasons and the occupied niches, in accordance with the respective strategies of resistance.

“…Studies focusing on plant functional traits and European coastal dunes have focused on three aspects. First, functional traits have been examined at the species level to explore plant adaptations to environmental factors (García-Mora et al 1999;Acosta et al 2006;Ciccarelli et al 2009Ciccarelli et al , 2010Spanò et al 2013;Retuerto 2013, 2014). Second, others have studied functional traits at the community level by analysing the relationship between functional diversity and the phylogenetic structure of plant communities (Ricotta et al 2012;Carboni et al 2013;Brunbjerg et al 2014).…”

Coastal dunes are characterised by strong interactions between biotic and abiotic factors along a short gradient from the shoreline to the inland region. We carried out an ecological analysis of the vegetation in a protected area of the Italian coast to evaluate the relationships among species abundance, the occurrence of morphoanatomical traits related to leaves, stems, and roots, and soil variables. Three transects were established perpendicular to the shoreline, with 27 plots distributed in the frontal dunes, backdunes, and temporarily wet dune slacks. An analysis based on community-weighted mean values showed that the pioneer communities of the frontal dunes were dominated by ruderals that are well adapted to the harsh ecological conditions of these environments, showing succulent leaves, high limb thickness values, and low values for leaf dry matter content (LDMC). The backdune vegetation was a mosaic of annual herbaceous and perennial shrub communities showing both ruderal and stress-tolerant strategies (clonality, sclerified leaves, high LDMC values, root phenolics) consistent with less extreme ecological conditions. The dune slack areas were dominated by plants showing adaptations to both arid and flooded environments, such as C4 photosynthesis, amphistomatic leaves, and abundant aerenchyma in the roots. The invasive status, C4 photosynthesis, leaf trichomes, and aerenchyma in the roots were significantly correlated with soil humidity, organic matter content, and pH. These results demonstrate the usefulness of anatomical traits (including root system traits) in understanding the functional strategies adopted by plants. Invasive species tended to occupy plots with high levels of soil moisture, suggesting an avoidance strategy for the harsh environmental conditions of coastal sand dunes. Finally, we suggest including information regarding root systems into coastal monitoring programs because they are directly linked to soil parameters useful in coastal dune management and protection.
