The Alien Vascular Flora of Tuscany (Italy)
Quad. Mus. St. Nat. Livorno, 26: 43-78 (2015-2016) 43 The alien vascular fora of Tuscany (Italy): update and analysis VaLerio LaZZeri1 SUMMARY. Here it is provided the updated checklist of the alien vascular fora of Tuscany. Together with those taxa that are considered alien to the Tuscan vascular fora amounting to 510 units, also locally alien taxa and doubtfully aliens are reported in three additional checklists. The analysis of invasiveness shows that 241 taxa are casual, 219 naturalized and 50 invasive. Moreover, 13 taxa are new for the vascular fora of Tuscany, of which one is also new for the Euromediterranean area and two are new for the Mediterranean basin. Keywords: Vascular plants, Xenophytes, New records, Invasive species, Mediterranean. RIASSUNTO. Si fornisce la checklist aggiornata della fora vascolare aliena della regione Toscana. Insieme alla lista dei taxa che si considerano alieni per la Toscana che ammontano a 510 unità, si segnalano in tre ulteriori liste anche i taxa che si ritengono essere presenti nell’area di studio anche con popolazioni non autoctone o per i quali sussistono dubbi sull’effettiva autoctonicità. L’analisi dello status di invasività mostra che 241 taxa sono casuali, 219 naturalizzati e 50 invasivi. Inoltre, 13 taxa rappresentano una novità per la fora vascolare di Toscana, dei quali uno è nuovo anche per l’area Euromediterranea e altri due sono nuovi per il bacino del Mediterraneo. Parole chiave: Piante vascolari, Xenofte, Nuovi ritrovamenti, Specie invasive, Mediterraneo. Introduction establishment of long-lasting economic exchan- ges between close or distant countries. As a result The Mediterranean basin is considered as one of this context, non-native plant species have of the world most biodiverse areas, especially become an important component of the various as far as its vascular fora is concerned. -
I1.3 Arable Land with Unmixed Crops Grown by Low-Intensity Agricultural Methods
European Red List of Habitats - Screes Habitat Group I1.3 Arable land with unmixed crops grown by low-intensity agricultural methods Summary Species-rich arable weed vegetation, characterised by now rare native and archaeophyte annual plants, is a survivor of ancient low-intensity agriculture and widely distributed across Europe but survives in abundance only in the mountainous areas of the Mediterranean region, particularly Italy. Since the intensification of agricultural practices in the middle of the 20th century, much of it subsidised by agri- environment funding, a significant decrease both in quantity and quality has been observed caused by excessive use of herbicides, biocides, and chemical fertilizers, improved seed-cleaning methods, sowing highly productive and competitive varieties of cereals, and removal of refugial habitats in the landscape due to merging of small fields into large ones. Such threats continue in many places, especially threatening surviving outliers. A large scale improvement of quantity and quality may require a revision of Common Agricultural Policy and agri-environment funding schemes and promotion of restoration initiatives. Synthesis Despite variable data quality, a lack of data from several countries and different interpretations of the habitat definition, the decreases in quantity and quality have been calculated using the territorial data from a sufficient number of countries to build an overall European average. Due to a large decrease in area over the last 50 years, the habitat qualifies for category Endangered under criterion A1. All countries except Italy (-20% to -40%) and Switzerland (-37.5%) reported a decrease in area between -50% and -99%. If the Italian and Swiss data were neglected, the overall assessment would result in category Critically Endangered. -

Isolation of P. syringae pv. atrofaciens from weeds of wheat crops was carried out by classical microbiological methods. To identify isolated bacteria, their morphological, cultural, biochemical, and serological properties as well as fatty acids and Random Amplification of Polymorphic DNA (RAPD)-PCR (Polymerase chain reaction) profiles with the OPA-13 primer were studied. Pathogenic properties were investigated by artificial inoculation of wheat plants and weed plants, from which bacteria were isolated. For the first time, bacteria that are virulent both for weeds and wheat were isolated from weeds growing in wheat crops. -

We arrived more or less on time at 1.30 pm and the customs and immigration formalities were brief, so we were soon able to be greeted by Yiannis, our local guide and botanist and see our first new common birds, Hooded Crow and Wood Pigeon. It was only a 20 minute drive to our comfortable hotel and after quickly settling in we set off at 3.15 pm to walk to the Tombs of the Kings, about three quarters of a mile away, seeing Iris Gynandriris sisyrinchium near the hotel and our first Sardinian Warbler along the way. On arriving at the tombs we found a strong onshore wind was keeping any birds very low and in cover, but we did see a number of Crested Lark and European Wheatear, as well as less common species such as Spanish Sparrow and Cretzschmar’s Bunting, while brief views were also obtained of Isabelline Wheatear. -
Effect of Small Ruminant Grazing on the Plant Community Characteristics of Semiarid Mediterranean Ecosystems

SALKINI AND STEVEN L. PETERSEN† International Center for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria †Plant and Animal Sciences Department, Brigham Young University, Provo, UT 84602, USA 1Corresponding author’s e-mail: [email protected] ABSTRACT Rangeland degradation has been widespread and severe throughout the Syrian steppe as a result of both unfavorable environmental conditions and human induced impacts. To explore the effectiveness of management-based strategies on establishing sustainable rangeland development, we compared the response of temporarily removing grazing from rangelands ecosystems to those under a continuous heavy grazing regime. Results indicated that ungrazed sites had both higher biomass production and plant species composition than grazed sites. Ungrazed plots produced more than fourfold herbaceous biomass production than continuously grazed plots (p < 0.001). Extent of plant cover was 20% greater in ungrazed plots than grazed plots (33.5 & 13.5%, respectively). Furthermore areas protected from heavy grazing had over 200% greater species composition. Thus, protection from grazing can increase forage production and species composition, but may not necessarily improve plant species available for livestock utilization. A more balanced grazing management approach is recommended to achieve an optimal condition of biomass production (quantity), vegetation cover, quality and available forage species that contribute to proving livestock grazing conditions.
