“…Indeed, out of more than 100 taxa listed in the 'physiognomic reference combination' , 34 are endemic. Of these, 20 are exclusive to the Sardinian flora (Arrigoni 2006(Arrigoni -2015Peruzzi et al 2014;Bartolucci et al 2018;Bagella et al 2020b).…”

The ‘Habitats’ Directive (HD 92/43/EEC) is one of the primary legal tools aiming at conserving nature in Europe. Due to the complex iter to revise it, the habitats listed in the Annex I have been seldom updated after the HD adoption. Basing on already available information and expert knowledge, this paper presents a preliminary list of relevant habitats occurring in Sardinia, not yet considered and worth to be placed in the Annex I. Two new habitat proposals, one habitat new for Italy, and nine new subtypes of already existing HD habitats are here described. Most of the proposed new habitats and subtypes have a limited distribution range, due to the high number of narrow, often endangered, endemic species that characterize them. Being neglected, they are consequently poorly investigated, inconstantly monitored and unprotected. Thus, the main aim of this paper is to promote their conservation through implementation of HD and its interpretation manuals.

“…It should be noticed that the model based on checklists or floras may also contain biases, since published lists often include extinct, cultivated and/or occasional species. In fact, the completeness of species lists affects biogeographic and ecological results and can depend on the amount of data collection (Sastre and Lobo, 2009;Aranda et al, 2010) but also on the taxonomic treatment (e.g., Bagella et al, 2020).…”

Aim: Ecoinformatics offer new opportunity to test islands as biogeographic and ecological models. In this paper we predicted three hypotheses: (1) plot-based data issuing from vegetation surveys can be used to predict Island Species-Area Relationships (ISARs) or island similarity; (2) the habitat area is an independent predictor of species richness patterns within island; (3) species richness and composition are more dependent on habitat type than island identity in land-bridge islands. Area: Tuscan Archipelago, Italy. Methods: We assembled a database of all the vegetation plots available for the archipelago. For the first hypothesis we calculated ISARs, using Arrhenius model, and Beta Diversity, using Jaccard dissimilarity, on both published floras and cumulative plot data. For the second hypothesis, we modelled Habitat Species-Area Relationships (HSARs), using Arrhenius model. For the third hypothesis, we used additive partitioning of species richness, NMDS and PERMANOVA. Results: Island Species-Area Relationships based on plot data mirrored those on published floras, but absolute values of c and z parameters were different. Beta diversity based on plot data resembled those of published floras, but was higher. Species richness was significantly related to the habitat area. The total species richness of the archipelago was linked to large scale drivers, such as island identity, while plot species composition was driven by both habitat type and island identity. Conclusions: Data assembled issuing from vegetation surveys are useful to describe biogeographic patterns. Species richness in the archipelago is driven by spatial factors such as the amount of habitats and the differences among islands, while the species composition of local assemblages is largely driven by habitat filters rather than by island identity, as expected in land-bridge islands.

“…44166,44167 and 44240) Although this species was reported for Sardegna by Giau (1986), its presence in the island was questioned and only the presence of Utricularia australis R.Br. was confirmed (Desfayes 2008;Arrigoni 2013;Bartolucci et al 2018;Bagella et al 2020;Orrù et al 2020). We localized a population of U. vulgaris alongside the Platamona lagoon, in Habitat 7210* "Calcareous fens with Cladium mariscus and species of the Caricion davallianae" (Gigante et al 2019).…”

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions for taxa in the genera Artemisia, Chaetonychia, Cirsium, Cynanchum, Genista, Hieracium, Iberis, Melica, Misopates, Myosotis, Thalictrum, Trifolium, Utricularia, Veronica, and Vicia. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as supplementary material.
