Vascular Plant Species Diversity of Mt. Etna
Vascular plant species diversity of Mt. Etna (Sicily): endemicity, insularity and spatial patterns along the altitudinal gradient of the highest active volcano in Europe Saverio Sciandrello*, Pietro Minissale* and Gianpietro Giusso del Galdo* Department of Biological, Geological and Environmental Sciences, University of Catania, Catania, Italy * These authors contributed equally to this work. ABSTRACT Background. Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt. Etna, the highest active volcano in Europe. Methods. We used all the available data (literature, herbarium and seed collections), plus hundreds of original (G Giusso, P Minissale, S Sciandrello, pers. obs., 2010–2020) on the occurrence of the Etna plant species. Mt. Etna (highest peak at 3,328 mt a.s.l.) was divided into 33 belts 100 m wide and the species richness of each altitudinal range was calculated as the total number of species per interval. In order to identify areas with high plant conservation priority, 29 narrow endemic species (EE) were investigated through hot spot analysis using the ``Optimized Hot Spot Analysis'' tool available in the ESRI ArcGIS software package. Results. Overall against a floristic richness of about 1,055 taxa, 92 taxa are endemic, Submitted 7 November 2019 of which 29 taxa are exclusive (EE) of Mt. -
List of 735 Prioritised Plant Taxa of CARE-MEDIFLORA Project
List of 735 prioritised plant taxa of CARE-MEDIFLORA project In situ and/or ex situ conservation actions were implemented during CARE-MEDIFLORA for 436 of the prioritised plant taxa. Island(s) of occurrence: Balearic Islands (Ba), Corsica (Co), Sardinia (Sa), Sicily (Si), Crete (Cr), Cyprus (Cy) Occurrence: P = present; A = alien (not native to a specific island); D = doubtful presence Distribution type: ENE = Extremely Narrow Endemic (only one population) NE = Narrow Endemic (≤ five populations) RE = Regional Endemic (only one Island) IE = Insular Endemic (more than one island) W = distributed in more islands or in a wider area. Distribution type defines the "regional responsibility" of an Island on a plant species. Criteria: Red Lists (RL): plant species selected is included in the red list (the plant should be EN, CR or VU in order to justify a conservation action); Regional Responsibility (RR): plant species selected plays a key role for the island; the "regional responsibility" criterion is the first order of priority at local level, because it establishes a high priority to plants whose distribution is endemic to the study area (an island in our specific case). Habitats Directive (HD): plant species selected is listed in the Annexes II and V of the Habitat Directive.

Is Palatability of a Root-Hemiparasitic Plant Influenced by Its Host Species?

Nature Conservation 22: 169–190. https://doi.org/10.3897/natureconservation.22.19809 Abstract Isolated populations are usually subject to low fitness and reduced genetic diversity, both of which may negatively affect their survival and adaptive potential. Hence, these issues cannot be neglected when plan- ning conservation actions for isolated populations. The Italian population of Cistus laurifolius subsp. lau- rifolius is extremely isolated. Furthermore, it is affected by fragmentation, being constituted by a single larger subpopulation, surrounded by three much smaller subpopulations, a few hundred metres to a few kilometres apart. -
Endemism in Recently Diverged Angiosperms Is Associated with Chromosome Set Duplication
Endemism in Recently Diverged Angiosperms Is Associated With Chromosome Set Duplication Sara Villa University of Milan: Universita degli Studi di Milano Matteo Montagna Universita degli Studi di Milano Simon Pierce ( [email protected] ) Università degli Studi di Milano: Universita degli Studi di Milano https://orcid.org/0000-0003-1182- 987X Research Article Keywords: adaptative radiation, apo-endemics, diversity creation, genome doubling, neo-endemism, speciation mechanism Posted Date: June 17th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-550165/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/22 Abstract Chromosome set duplication (polyploidy) drives instantaneous speciation and shifts in ecology for angiosperms, and is frequently observed in neo-endemic species. However, the extent to which chromosome set duplication is associated with endemism throughout the owering plants has not been determined. We hypothesised that across the angiosperms polyploidy is more frequent and more pronounced (higher evident ploidy levels) for recent endemics. Data on chromosome counts, molecular dating and distribution for 4210 species belonging to the major clades of angiosperms were mined from literature-based databases. As all clades include diploid taxa, with polyploids representing a possible ‘upper limit’ to the number of chromosomes over evolutionary time, upper boundary regression was used to investigate the relationship between the number of chromosomes and time since taxon divergence, both across clades and separately for families, with endemic and non-endemic species compared. A signicant negative exponential relationship between the number of chromosomes and taxon age was 2 evident across angiosperm clades (R adj=0.48 with endemics and non-endemics considered together, 2 2 R adj=0.46 for endemics; R adj=0.44 for non-endemics; p ≤0.0001 in all cases), which was three times stronger for endemics (decay constant=0.12, cf. -

Primary succession on slopes exposed to intense erosion: the case of Vesuvius Grand Cone Adriano Stinca, Giovanni Battista Chirico, and Giuliano Bonanomi Università di Napoli, Dipartimento di Agraria, Portici (NA), Italy ([email protected]) Mt. Vesuvius (1281 m a.s.l.) is an active volcano dominating the central part of the Campania Region coastline, with a distinctive barren crater summit, known as Grand Cone, formed during the eruption of AD 79. Local envi- ronmental factors hindered the colonization of the Vesuvius Grand Cone by vascular plants after the last eruptions of 1906 and 1944. The Grand Cone exhibits very steep planar slopes (33-35 degrees), covered by unconsolidated pyroclastic deposits, mainly formed by lapilli and gravels, characterized by an extremely low water holding ca- pacity and very low organic matter and nitrogen contents, and exposed to intense water and wind erosion. In the last decade Genista aetnensis (Biv.) DC. (Fabaceae), has been expanding over the Grand Cone, facilitating the colonization by other species, especially herbaceous, with a dramatic change of the landscape appearance of the Vesuvius Grand Cone. G. aetnensis is a plant endemic of Mt. Etna and Eastern Sardinia and was firstly introduced at the base of Mt. Vesuvius within reforestation programs after the eruption of 1906. This plant is a nitrogen fixing species with a strong ability to colonize andosols, much more pronounced than the indigenous brooms (Cytisus scoparius and Spartium junceum). An intensive investigation has been conducted to explore the eco-hydrological processes driving the vegetation dynamics observed on the slopes of Grand Cone. -
