Open-access field and spatial data are increasingly available worldwide, but their contribution to modelling vegetation alliances remains to be assessed. This study aimed to map the suitability area of six heath alliances distributed along ecological gradients throughout France. We used 20 broad and local variables derived from WorldClim, the European Union DEM, SoilGrids, and the Global Wind and Solar Atlases that describe bioclimatic and environmental conditions. For each alliance, two nested MaxEnt models were calibrated and validated using archive field data: one at a broad scale (1000 × 1000 m) to define its bioclimatic area, and the second at a local scale (25 × 25 m) to predict its environmental area. The results showed complementarity of the variables used to discriminate the alliances, and the accuracy of spatial modelling at broad (AUC = 0.83–0.99) and local scales (AUC = 0.91–0.99). They also highlighted the gradients of continentality and temperature that differentiate the alliances. These new maps provide additional knowledge about alliance distribution areas and could support natural vegetation conservation at a national scale.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"48 1","pages":"379 - 391"},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87390861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighteen compounds were detected in methanol extract with ellagic acid (88.06 g/kg), as the major constituent. Ethyl acetate and methanol extracts inhibited α-amylase with half-maximal inhibitory concentration (IC50) values of 9.16 and 8.33 μg/mL, respectively. The ethyl acetate and methanol extracts exerted a non-competitive and a competitive inhibition on α-amylase enzyme, respectively. This activity was supported by molecular docking analysis of some major compounds of both extracts. All these compounds showed a low binding energy and they could bind with the key residues including ASP-206 and GLU-230 of the α-amylase enzyme and these ligands were also surrounded by other active site residues. These findings suggest that P. pinea extracts could serve as safe and efficient α-amylase inhibitors to treat postprandial hyperglycemia in diabetic patients.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"15 1","pages":"357 - 366"},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74927981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the diversity of Iberian gall oak forests is resolved into 15 associations characterised according to their floristic, biogeographical, bioclimatic and synecological data supported by the statistical analyses. Thirteen have been described previously, and two new associations are proposed: Glandoro diffusae-Quercetum fagineae and Helianthemo mollis-Quercetum fagineae. A new combination, a lectotypification and a nomenclatural correction are also proposed. The Ios2 (ombrothermic index of the warmest bimonth of the summer quarter), Itc (compensated thermicity index) and Ic (continentality index) indexes proved to be fundamental to explain the syntaxonomic differentiation of the forests in the study.

Our study showed that these fruits are different for their surface and shape: in particular, P. anisoides monocarps are glabrous, whereas the other two species are strigose. Two main compounds were identified in the essential oil of the five studied accessions: limonene (46.78-50.74%) and anethole (38.50-42.77%) whose sum ranged between 85.28 and 93.51%. estragole and β-phellandrene were other two representative compounds. All other volatiles accounted for less than 1% of the total volatile composition. One-way ANOVA analysis showed significant differences in almost all volatiles, whereas non-significant differences were found in the compounds detected in very low quantity. Hierarchical cluster analysis allowed to group the five accessions in three main clusters. Principal Component Analysis (PCA) showed that the first two principal components explained 71.80% of total variance.

In Italy, it can be found in different ecological contexts, often giving rise to diversified coenoses. Due to its ecological plasticity, G. radiata communities have been considered sometimes as simple dynamic variants of grasslands aspects, sometimes as more or less stable shrublands and this interpretation has changed over time. The aim of this study was to analyze the coenological and ecological features of all Italian G. radiata communities. An Italian comprehensive data-set has been investigated by means of multivariate analysis. Ecological and chorological analyses were performed, and the diagnostic species of different groups were identified through the phi coefficient of association. According to our analysis, nine different types of G. radiata communities were found to be present in Italy. Each group was characterized by means of its floristic, ecological and chorological components and investigated as to its syntaxonomic aspects. This allowed us to attribute the Italian G. radiata communities to nine different associations, four of which already existing and five proposed as new or as stat. nov.
