Fungal biodiversity and in situ conservation in Italy

2011

A remarkable increase in knowledge of fungal biodiversity in Italy has occurred in the last five years. The authors report up-to-date numbers of fungi (Basidiomycota and Ascomycota) by regions together with distributional and ecological data on hypogeous fungi. Specific case studies such as alpine fungi, orchid mycorrhizas symbionts, invasive species, and the use of macrofungi as food by red squirrels are analyzed. In situ conservation strategies carried out on target species and/or taxonomic groups are also indicated.

Dwuizbowy parlament i reformy instytucjonalne w Republice Włoskiej

2019

Parlamenty z natury są instytucjami dwoistymi, gdyż łączą społeczeństwo z prawną strukturą władzy państwowej. Analiza właściwości strukturalnych współczesnych legislatyw wskazuje, że szczególnie istotny jest czynnik organizacji wewnętrznej pozwalający wyodrębnić bikameralizm symetryczny. Przypadek Republiki Włoskiej przyciąga badaczy ustrojów politycznych z wielu powodów. Między innymi z tego względu, że obie izby posiadają identyczną pozycję prawnoustrojową, taką samą długość pięcioletniej kadencji oraz dysponują identycznymi kompetencjami. Proporcjonalna ordynacja wyborcza (poza dwoma wyjątkami) gwarantowała, że legislatywa była lustrzanym odbiciem społeczeństwa, umożliwiając spotkanie ró…

Isoëtes todaroana (Isoëtaceae, Lycopodiophyta), a New Species from Sicily (Italy)

2009

Isoetes todaroana, a new species from western Sicily (Italy), is described. Morpholog- ical, anatomical and ecological characters are given. The main differential characters are the presence of only two leaf air chambers, rather than four as in all other known species of the genus, and the shape of the scales, which have two lateral rounded lobes and one central spine-like lobe, together with its peculiar calcophilic habitat. So far, the species is known from a single locality.

On the real identity of the Strelitzia cultivated in Sicily’s historic gardens

2016

The authors, on the basis of field observations and literature search, conclude that all tree-like plants of Strelitzia grown in Sicily belong to Strelitzia nicolaii. Therefore Strelitzia alba (= Strelitzia augusta), which was generally considered to be commonly cultivated in Sicily since the nineteenth century, if it ever was cultivated on the island, is not currently found there. The Lectotypes of the names S. nicolaii and S. alba are here designated.

Lampedusa humanitarian emergency in 2011: the case of unaccompanied migrant minors

2012

The purporse of this paper is to highlight the situation of the unaccompanied foreign minors in the Italian legal system, paying special attention to the Lampedusa humanitarian emergency in 2011. The paper examines the legal measures regulating the status of unaccompanied foreign minors in the Italian legal system, in order to understand if they are efficient in giving protection and offering integration to these minors. The papers offers insights into the most vulnerable category of illegal immigrants Purpose - The purpose of this paper is to highlight the situation on the unaccompanied foreign minors in the Italian legal system, paying special attention to the Lampedusa humanitarian emerg…

Root and Basal Stem Rot of Rose Caused by Phytophthora citrophthora in Italy

2011

Approximately 800 ha of cut flower roses are cultivated for commercial production in Italy. During autumn of 2004 in an experimental greenhouse in western Sicily (southern Italy), 60% of 2-year-old plants of rose cv. Red France on Rosa indica cv. Major rootstock grown in soil showed leaf chlorosis and wilt. A dark brown lesion lined by a water-soaked area was noticeable at the stem base near the soil surface. Root rot was found consistently associated with aboveground symptoms and plants collapsed within 4 months after the appearance of the first symptoms. The same symptoms were observed sporadically on rose plants of the same cultivar during the last 6 years in commercial nurseries in wes…

The marine diapsid reptile Endennasaurus from the Upper Triassic of Italy

2005

The marine reptile Endennasaurus from the Upper Triassic Zorzino Limestone of northern Italy is rede- scribed and reassessed. New details of the skull and postcra- nial skeleton are revealed, confirming the attribution of this genus to the diapsid reptile clade Thalattosauriformes. Phylo- genetic analysis suggests that Endennasaurus was related to the European genus Askeptosaurus and the Chinese Anshun- saurus. Despite a rather conservative postcranial morphology, Endennasaurus clearly occupied a highly specialized dietary niche as it combined a slender tapering premaxillary rostrum with a complete absence of either marginal or palatal teeth.

Typification of the name orobanche ebuli huter & rigo (orobanchaceae) and its taxonomic implications

2018

The present contribution is part of the ongoing work aimed at researching and identifying the original material on which the names of Orobanche Linnaeus (1753: 632) described for Europe and the Mediterranean are based (Domina et al. 2005, Domina & Stepanek 2009, Domina et al. 2013, Carlón et al. 2015). It falls within the researches promoted by the Italian Botanical Society aimed at recognizing and typifying all the taxa described from Italy and their loci classici, in order to increase their systematic knowledge and promote further studies (Domina et al. 2012, Peruzzi et al. 2015, Brundu et al. 2017). Orobanche ebuli Huter & Rigo (1907: 354), is an Italian endemic (Peruzzi et al. 2…

Seed germination in the Sicilian subspecies ofDianthus rupicolaBiv. (Caryophyllaceae)

2012

Abstract Five populations belonging to three subspecies of Dianthus rupicola Biv. (D. rupicola subsp. rupicola, D. rupicola subsp. aeolicus, and D. rupicola subsp. lopadusanus) and growing in different geographical areas of Sicily were tested for seed germination at various temperatures. All populations showed high germination rates with an optimum temperature between 15°C and 25°C. Efficient seed germination might contribute significantly to the preservation of these subspecies which are currently exposed to several environmental threats.
