Halophilous vegetation of Olbia pond system (NE-Sardinia)

Authors report some results about a phytosociological study concerning the wetlands to the south of Olbia (Gallura, north-eastern Sardinia). Vegetation analysis allowed to detect 21 associations, among them two are new and denominated Halimionio portulacoidis-Limoniastretum monopetali ass. nova and Ephedro fragilis-Pistacietum lentisci ass. nova. Among them, the association Halimiono portulacoidis-Limoniastretum monopetali shows a particular phytogeographical interest, because it sets the Limoniastrum monopetalum vegetation in the only Sardinian station of this shrubby Plumbaginacea. From a syntaxonomic point of view, described syntaxa are included in 9 vegetation classes. Plant landscape of the area was reconstructed by the study of chain contacts among different communities, placed in space according to humidity and salinity gradients, determined by substratum texture and micromorphology. On the basis of phytocoenotic diversity stressed by this research, this study area is believed to be deserving of protection aiming at conserving and managing its populations and plant communities

Two new species of the flea beetle genus Psylliodes Latreille of the montana species-group from Eastern Africa (Coleoptera: Chrysomelidae)

In this paper, Psylliodes afromontana sp. nov. and P. shira sp. nov., both from Eastern Africa [Kenya (Kikuyu Escarpment) and Tanzania (Kilimanjaro) respectively], are described. The two new species are attributed to the montana species-group, currently including four other wingless species occurring in the montane forests of Kenya and Tanzania: Psylliodes montana Weise, P. kikuyana Biondi, P. masai Biondi, P. manobioides Nadein. Micrographs of diagnostic characters, comprehending male and female genitalia are supplied. Ecological data for each species, including habitat preference, and phenology are also reported

A phytosociological investigation on the mixed hemycryptophitic and therophitic grasslands of the Cornicolani mountains (Lazio Region – central Italy)

Abstract In this paper a phytosociological study on the dry grasslands of the Cornicolani mountains is presented. The Cornicolani are a group of isolated limestone hills which emerge from the slightly ondulating grounds of the Rome countryside in the Tyrrhenian side of the central Italy. Eighty-nine relevés were performed using the Braun-Blanquet phytosociological approach. These were further subjected to hierarchical classification and to NMDS ordination. Five major types of grasslands were distinguished: short therophytic grasslands developed on shallow soils dominated, in turns, by Hypochaeris achyrophorus, Plantago lagopus and Plantago bellardii; sub-nitrophilous detriticolous perennial grasslands dominated by Dittrichia viscosa and Helichrysum italicum; Dasypyrum villosum and Vulpia ligustica lawn and fallow annual tall-grasslands; Ampelodesmos mauritanicus grasslands of the rocky S-facing slopes and sub-mesophilous Lolium perenne and Cynodon dactylon grasslands of the flat and pastured areas. From a syntaxonomical standpoint a new associations named Plantaginetum afrae-bellardii was proposed and included in the class Stipo-Trachynetea. In addition the association Helichryso italici-Inuletum viscosae Trinajstić 1965 (nom. inval.) was here validated

The Vegetation of S'Ena Arrubia lagoon (centre-western Sardinia)

This study describes the vegetation of S'Ena Arrubia lagoon, in the Gulf of Oristano, in the centre-western coast of Sardinia. This lagoon is classified as: Special Protection Zone (S.P.Z.) according to EEC Directive 79/409, community importance site according to EEC Directive 92/43, I.B.A. (Important Birds Area) site and fixed oasis of fauna protection and natural reserve. Throughout the years it was subject to several alterations. The most important ones were carried out in the Seventies and allowed the marine water upwelling and the fast removal of freshwater coming from the watershed. Before the fulfilment of these interventions, lagoon waters had a low salinity, as demonstrated by previous vegetation studies that showed the presence of freshwater communities and, only to a smaller extent, of halo-tolerant and halophile ones. This phytosociologic study led to the identification of several associations that are showed in the groups of merely halophile vegetation, in the freshwater and subhalophile lagoon vegetation and in the merely anthropogen vegetation typologies. The location of the considered typologies is represented with distributive patterns, which synthesise the current state of vegetation referring to the salinity. Two new associations, the Inulo crithmoidis-Paspaletum vaginati and the Astero tripolii-Bolboschoenetum maritimi, are here described. The first is dominated by the presence of Paspalum vaginatum Swartz, recorded for the second time in Italy and for the first time in Sardinia. It is recorded near the inlet, where it forms mosaics together with Salicornietum emerci association and it is also present, as bolboschoenetosum maritimi subassociation, in more inland and less salty zones. The latter new association includes the subhalophile reedswamps that are present in the areas floodcd by salty waters for a long time, where it replaces the Scirpetum compacto-littoralis, a less halophile association present in several siles of the Mediterranean and also in Sardinia. In addition, it is necessary to point out the recovery of Salicornietum venetae association, characterised by the presence of Salicornia veneta Pign. et Lausi, which was believed endemic in the North Adriatic lagoons. Finally, the significance of environmental changes fulfilled in the basin, which are the reason for some vegetation modifications and are detected by comparison between current associations and those at the beginning of the Seventies, is pointed out

Plant communities of Italy. The vegetation prodrome

The Vegetation Prodrome of Italy was promoted in 2012 by the Italian "Ministry of Environment, Land and Sea Protection", in collaboration with the "Italian Society of Botany", to provide a comprehensive and systematic catalogue and description of Italian plant communities. The Prodrome that is presented in this paper is the first full organic synthesis of the vegetation of Italy at the alliance syntaxonomic level. It fulfils several needs, the main one being a unified and comprehensive national framework that may make an important contribution to the definition of the European Vegetation Prodrome. Syntaxonomy, as well as taxonomy, is sometimes based on considerations that may in part diverge: several authors tend to favour models that are divisive or aggregative to a greater or lesser extent in terms of flora, biogeography and ecology. These different points of view stimulate the scientific debate and allow the adoption of a framework that is more widely supported. The Prodrome includes 75 classes, 2 subclasses, 175 orders, 6 suborders and 393 alliances. The classes were grouped into nine broad categories according to structural, physiognomic and synecological elements rather than to syntaxonomic criteria. The rank, full valid name, any synonymies and incorrect names are provided for each syntaxon. The short declaration highlights the physiognomy, synecology, syndynamics and distribution of the plant communities that belong to the syntaxon. The Prodrome of the Italian Vegetation is linked to the European Strategy for Biodiversity, the European Habitats Directive and the European Working Groups related to the ecosystems and their services. In addition to basic applications, the Prodrome can be used as a framework for scientific research related to the investigation of the relationships between plant communities and the environmental factors that influence their composition and distribution
