No full textA new plant association describing the dominated Lamium garganicum subsp. striatum vegetation is here proposed. This vegetation occurs on the calcareous screes with
medium-size stones in the lower subalpine belt of the Abruzzo region and it is linked to environment with some nitrate content. The association is included in the Apennine alliance

Contribution to knowledge of Apennine colline-submontane garigues on terrigenous rock types
No full textThis study provides new data and an in-depth syntaxonomic analysis of Apennine garigues in the Cisto cretici-Micromerietea julianae class, relative
to terrigenous substrates in temperate bioclimates. In this context, it is proposed to elevate the suballiance Astragalenion monspessulani Biondi,
Allegrezza & Zuccarello 2005 to the rank of alliance, with the name of Astragalion monspessulani, and to introduce the new Astragaletalia monspessulani
order. The study also describes a number of new associations and subassociations belonging to the Astragalion monspessulani and Cisto cretici-Ericion manipuliflorae alliances

No full textUnderstanding the abiotic factors influencing biodiversity patterns on Earth is a crucial task for conservation scientists. At the regional level, meso-climate factors, primarily associated with elevational gradients, are of great importance. However, disentangling these factors can be challenging due to the influence of other variables, such as geological substrata. To address this issue and better understand elevational gradients, it is essential to study geologically homogeneous terrains, particularly in Mediterranean islands where such research is lacking. In this study, we investigated the distribution of plant species richness along the elevational gradient of the Limbara massif, which consists predominantly of granite rocks and ranks as the third-highest peak in Sardinia at 1359 m a.s.l. We employed generalized linear models to analyze richness patterns, considering various factors, including all plant species, functional species groups categorized by Raunkiær life forms, chorological groups of species, alien species and phylogenetic diversity. Our findings revealed a hump-shaped model of species richness along the elevational gradient, with lower elevations exhibiting the highest species richness. Additionally, endemic species richness increased with higher elevations, while alien species were predominantly found at lower elevations. These results indicate that the Limbara massif possesses a significant elevational gradient in species composition, likely reflecting a unique plant evolutionary history. Furthermore, we emphasize the importance of published floras as valuable sources of biodiversity data for such studies
