The aim of this study is to shed light on plant physiognomy and landscape changes which have characterized the Abruzzo coast in the past, analysing different historical documents in order to join the information with those related to the actual vegetation focusing on some events and historical processes which influenced the modification of the landscape, causing a huge spillover on natural environment and relapse of the soil use. The existence of different types of coastal woodlands is documented by some texts and geographic maps showing that in the past centuries the Abruzzo coast was covered by thick and impervious forests named "selvae", which were integral part of the economy of local populations, mostly based on non-wood products. About the past plant physiognomy, most of the available information are fragmentary, but a few well detailed documents give an acceptable representation of some plant formations, as in the case of large coastal pine woods, which have been remodeled and reshaped over time, even with reforestation and are today restricted in small areas. Many documents are also important to prove the close link between these formations and the daily life of local people in the past, underlining at the same time their cultural and historical-environmental value. The study of this documentation is also useful for the analysis of those species whose presence status is nowadays considered critical or cryptic, as well as for the study of introduced species which are now historicized in the landscape and in some cases have become typical. © 2014 Italian Society for Vegetation Science.

The alliance Cynosurion cristati has been found by various authors across the European continent. However, the fact that its diagnosis is based on species that are found in a wide range of geographical and ecological conditions and on the absence of grazing-sensitive species has rendered the characterization of this alliance somewhat complicated. The aims of this paper were: i) to investigate differences in the composition of some European mesophilous pastures, with particular focus on Italy; ii) to assess the main factors underlying these changes; iii) to evaluate the need for a new classification for such communities in the Italian peninsula. We used previously published data from several other European countries and both published and unpublished data from Italy. A synoptic table of data from different parts of Europe was analysed by means of hierarchical clustering. We used Multi-Response Permutational Procedure and phi coefficient to test differences between Cynosurion clusters and identify their diagnostic species. We performed Non-metric Multi-Dimensional Scaling on a table of 111 Italian releves. Kendall's correlation coefficient was calculated by relating the releve scores in the ordination with the geographical, environmental variables, and with the Ellenberg indices relative to soil conditions. The first axis scores were also used as the dependent variable in a regression tree. Important compositional differences were found within the Cynosurion cluster, with significant differences emerging between the Apennine pastures in central and southern Italy and those in northern and central Italy. The first axis ordination was strongly related to the latitudinal/thermal gradient. Indeed, latitude and temperature were the most important variables in the regression tree. Our results highlight marked compositional variation in Cynosurion grasslands. This variation, which is related in the Italian peninsula to bioclimatic and biogeographical factors, led us to propose a rearrangement of the existing classification of the alliance for this part of Europe. © 2012 Gebrüder Borntraeger, 70176 Stuttgart, Germany.

The new alliance Cerastio tomentosi-Globularion meridionalis and the new association Helianthemo alpestris-Globularietum meridionalis are here proposed as a contribute to the prodrome of Italian vegetation. The new syntaxa are related to the chamaephytic high-mountain vegetation and they are characterized by a wide presence of endemics, southern European orophytes, mountain-Mediterranean, and amphi-Adriatic species. The proposal aims to differentiate, on a structural basis, the high-mountain vegetation of the Apennines at higher syntaxonomical levels. © 2015 Societa Botanica Italiana

Context: There is a need for the discovery of novel natural remedies to prevent and treat metabolic disorders such as hyperglycemia, type II non-insulin-dependent diabetes mellitus, and obesity. Several Achillea species have been utilized for centuries all around the world and are generally considered effective as hypoglycemic. Objective: Considering the ethnobotanical uses of Achillea genus, we evaluated the in vitro inhibitory activity of Achillea tenorii Grande (Asteraceae) extract on a-glucosidase, which is a valuable target to prevent and treat metabolic disorders. We also tested its antioxidant activity. Moreover, the phytochemical profile was discussed from a chemotaxonomic point of view. Materials and methods: In vitro α-glucosidase inhibition of crude ethanolic extract obtained from the aerial parts was assayed as well as the in vitro antioxidant activity (ABTS, DPPH, and FRAP-FZ tests) was measured. The extract was characterized from a phytochemical point of view by means of spectroscopic analysis. Results: The extract results endowed with α-glucosidase inhibitory activity (IC50 32 μg/mL) with a particular mechanism of action definable as un-competitive, which differed from the mechanism observed for the best-known α-glucosidase inhibitor (acarbose and miglitol). In addition, a considerable antioxidant potential has been found for A. tenorii extract, which resulted mainly constituted by phenolic compounds such as caffeoylquinic acids and flavonoids. Discussion and conclusions: These results suggest the potential of A. tenorii as a possible natural remedy to prevent and treat metabolic disorders of carbohydrates. © 2015 Informa Healthcare USA, Inc.

This work presents the first reported phytochemical study on the hydro-distilled essential oil from Achillea tenorii (Grande), collected in the protected area of Majella National Park (Italy). The composition of the essential oil was very different from those reported for the other species of Achillea nobilis group, being constituted mainly by oxygenated monoterpenes, among which ketones, alcohols and acetates compounds were the most representative. The marker compounds of A. nobilis group were not detected while the most abundant phytoconstituents were α-thujone (29.7%), trans-sabinol (18.6%) and trans-sabinyl acetate (15.7%), revealing a composition quite similar to that of Artemisia absinthium. © 2014 © 2014 Taylor & Francis.

We report here on very rare associations (7) of the Abruzzo coast that are unusual for this Region (16). Moreover, we propose a new association of the alliance Crucianellion maritimae. © 2014 Italian Society for Vegetation Science.

After a brief introduction on the causes of the degradation and the conservation status od Abruzzo coast, we highlight the dynamics of the coastal vegetation systems in Abruzzo over the past 35 years. This is provided through a comparison between the previous situation, as documented by the data in the literature, and the current situation. The study highlights a worrying loss of phytocoenotic biodiversity that affects large sections of the coast, with the extinction of very rare halophilic plant associations not only for Abruzzo, but also throughout the central-southern Adriatic coast. On a positive note, we highlight the presence of newly established plant communities for some of the coastal segments. © 2014 Italian Society for Vegetation Science.
