Most of the surveyed associations are linked to hoed cultivations. Major differences are determined by the tillage and watering regimes, on their turn related to the life-cycle of the cultivated plant.

The aims of this study were twofold. First, to provide data on the genetic diversity of pubescent oaks from an understudied area which currently exhibits one of the highest concentrations of pubescent oak species in Europe. Second, to verify if these groups of oaks are genetically distinct and if their identification is in accordance with the current taxonomic classification. Molecular analyses of leaf material of 480 trees from seventeen populations belonging to putatively different pubescent oak species (Quercus amplifolia, Q. congesta, Q. dalechampii, Q. ichnusae, Q. leptobalanos, Q. virgiliana) were performed. Twelve gene-based Expressed Sequence Tag-Simple Sequence Repeat markers were selected, and genetic diversity and differentiation were calculated. The results showed relatively high values of allelic richness, heterozygosity and number of private allele...

The alien flora of the Calabria region (Southern Italy) representing almost 12% of the regional flora and comprises 381 alien taxa, among which there are 370 angiosperms, 9 gymnosperms and 2 ferns. In relation to the state of spread, 35 invasive alien species (IAS) have been identified (4 of these are included in the list of Union Concern, sensu Regulation (EU) no. 1143/2014) which represent 9% of the Calabrian alien flora.In the last years the alien flora in Calabria has increased: in particular, alien species have increased over a decade from 190 to the current 381 taxa. If on the one hand this is due to new introductions, resulting from the globalization that relentlessly affects the whole planet, on the other hand it is to be linked to awareness of the problem of alien species and the increasing intensity of research in recent decades. This study would provide a baseline for further advanced studies on the ...

One critical group is Juniperus oxycedrus L., especially from the taxonomical point of view. For this reason, we have studied the ecology, taxonomy and distribution of the taxa in the J. oxycedrus group. From an ecological and distribution standpoint, in this work we use the ombroedaphoxeric index (Ioex) to explain the presence of Juniperus populations in ombrotypes that are not optimum for these taxa. The controversy over the taxonomy of J. oxycedrus subsp. badia (H. Gay) Debeaux and J. oxycedrus subsp. lagunae (Pau ex C. Vicioso) Rivas Mart. is clarified, and it is accepted as a valid name, J. oxycedrus subsp. badia. The phytochemical differences in essential oils (EO) are addressed and their similarities analyzed; greater similarities are observed between oxycedrus and badia, and between navicularis Gand. and macrocarpa (Sm.) Ball. species. The phytochemical, molecular ...

In these unstable ecological conditions, a considerable diversity of plant communities occurs. The objective of this study, carried out in the Algarve and Monchique, and the Mariánica Range biogeographical sectors, is to compare chasmo-chomophytic communities of the southwestern Iberian Peninsula, using a phytosociological approach (Braun–Blanquet methodology) and numerical analysis (hierarchical cluster analysis). From these results, two new communities were identified, Sanguisorbo rupicolae-Dianthetum crassipedis and Antirrhinetum onubensis, as a result of floristic and biogeographical differences from other associations already described within the alliances Rumici indurati-Dianthion lusitani and Calendulo lusitanicae-Antirrhinion linkiani, both included in the Phagnalo saxatilis-Rumicetea indurate class.

Il Progetto SIMBIOTIC ha tra i suoi obbiettivi l'incremento della connettivita ecologica tra l'isola di Gozo e la Sicilia sud-orientale, il miglioramento gestionale delle aree protette presenti, l'approfondimento e la divulgazione delle conoscenze sul patrimonio naturalistico. Lo studio diacronico, che ha analizzato le trasformazioni del paesaggio avvenute negli ultimi 150 anni, ha messo in evidenza un costante aumento della frammentazione dovuta all'intensificazione e specializzazione dell'attivita agricola e all'urbanizzazione della fascia costiera. Per le aree umide costiere non si riscontrano consistenti riduzioni di superficie, mentre risulta alterata la loro f...
