Plant hunting: exploring the behaviour of amateur botanists in the field
2021
We asked what are the behavioural and logistic preferences of professional and amateur botanists when exploring flora in the field. We extracted temporal and spatial data on vas- cular plant species occurrences from three datasets of Sicilian flora: a subset of iNaturalist, a dataset collected by a Facebook group focused on the flora of Sicily and a subset of the professional database European Vegetation Archive. We used the time span of individual contributor’s activity as a proxy of their commitment to collecting information about the flora of Sicily. Climate and landscape data were used to better characterize the spatial and temporal activity of data contributors. Finally, we assessed wh…
Asian relationships of the flora of the European Alps
2008
Background: It has long been recognised that the Alps have strong biogeographical links to Asia. Aims: We investigate here whether the two areas are connected either through southern (mountain chains between the Alps and the Himalayas) or through northern regions. Methods: We compiled the geographical distribution of plant genera growing both in the Alps and the Himalayas, and outside these two regions. This compilation was used to search for molecular phylogenetic literature which was screened for area relationships informative for our purposes. Results: Of 933 genera growing in the Alps, 653 were considered further. Of the 429 genera growing in the Alps and the Himalayas, 218 grow in both…
Ellenberg’s Indicator values for the Flora of Italy – first update: Pteridophyta, Gymnospermae and Monocotyledoneae
2012
Ellenberg’s indicator values are an useful tool to delineate the relationship between plants and environment, recognising to each species a functional role as biological indicator. In the frame of the second edition of the Pignatti’s “Flora d’Italia”, some new informative systems are under preparations, in order to support geobotanical/applied studies, including a complete and updated review of the Ellenberg’s indicator values for the whole bulk of species mentioned in the flora of Italy. This first contribution includes a list of 380 species of Pteridophyta, Gymnospermae and Monocotiledoneae that complete the first assignment of the Ellenberg’s indicator values to the flora of Italy, publi…
New records and observations to the Characean flora (Charales, Charophyceae) of Sicily (Italy)
2019
New records to the Characean flora of Sicily are presented. Five species (Chara baltica, C. conimbrigensis, C. oedophylla, Nitella gracilis, Tolypella salina) are new to Sicily, two of them being also new to Italy (Chara conimbrigensis, C. oedophylla). Two species are confirmed for Sicily (Chara aspera, Nitella opaca), three (Chara braunii, C. canescens, Nitella capillaris) are rare taxa. The Characean flora of Sicily, updated with these records, currently includes 25 species, distributed in four genera: Chara (13 species), Nitella (eight species), Tolypella (three species) and Lamprothamnium (one species).
Measurement and Conservation of Species and Habitat Biodiversity at Different Scales on Small Mediterranean Islands
2021
In this paper we discuss current methodologies for measuring biodiversity, analyse pros and cons at different scales, and finally propose distribution mapping as the most suitable method for measuring floristic biodiversity on small Mediterranean islands. These territories often host endangered flora and habitats, and have peculiarities that distinguish them from the mainland and the larger islands.
Notulae to the Italian native vascular flora: 12
2021
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. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.
Contributo alla conoscenza floristica dei monti Sicani (Sicilia): resoconto dell’escursione del Gruppo di Floristica (S.B.I.) nel 2012
2015
The results of the excursion of the “Gruppo di Floristica” of the Italian Botanical Society held in the Sicani Mountains (CW-Sicily) on May 3-6, 2012, are here presented. During the research a total of 532 taxa was recorded. Three of them, the native Rosa squarrosa and the alien Phyllostachys aurea and Vitis ×koberi are new to Sicily, and 14 are new to the Sicani Mts. On the other side, we confirm the exclusion of Erica manipuliflora from the flora of the region.
Caucalido platycarpi-Vicietum michauxii — a new weed association from crop fields of Kyrgyzstan (Middle Asia)
2014
Abstract The study presents the results of geobotanical investigations conducted in crop fields in the western Tian Shan Mts in Kyrgyzstan (Middle Asia). The main research focused on classification of weed communities developing within this poorly investigated area, were conducted in the vicinity of Bishkek and Kara-Balta in 2010. Altogether, 299 phytosociological relevés were sampled using the Braun-Blanquet method. Based on all segetal vegetation patches, the analyses distinguished a new association: Caucalido platycarpi-Vicietum michauxii. The results of these phytosociological studies fill a gap in the knowledge about the syntaxonomical diversity of the Middle Asia region, which is one …
Genetic diversity in Cytisus aeolicus Guss. (Leguminosae), a rare endemite of the Italian flora
1998
ABSTRACT Cytisus aeolicus Guss, is an endemic plant restricted to the isles of Vulcano, Stromboli and Alicudi in the Aeolian archipelago. All known populations were assayed for genetic variability using enzyme polymorphism. Allozyme variation at 16 loci coding for 10 enzyme systems was examined. The great majority of loci turned out to be monomorphic or fixed heterozygous. The observed genetic depauperation is indicative of historical factors, such as the bottleneck effect associated with migration, and the founder effect in population re-establishment. The low genetic diversity is largely partitioned within rather than among populations, indicating that extant populations have not been est…
A first contribution to the cryptogamic flora of “Bosco Pomieri” (Northern Sicily)
2020
This is the first contribution to the cryptogamic flora (algae, bryophytes, fungi and lichens) of the “Bosco Pomieri”, an old-growth forest included in the Madonie Regional Park (N-Sicily). This area presents a significantly high biodiversity (41 algae, 41 bryophytes, 141 fungi, and 105 lichens) and also hosts several taxa of high biogeographic value.
