Gli Anemoni Bianchi Sono Piante Molto Belle E Diffuse
14 maggio 2011 (f.f.) gli anemoni bianchi sono piante molto belle e diffuse sulle nostre montagne anche se non creano i meravigliosi tappeti fioriti presenti nei boschi di latifoglie del nord-Europa. Distinguiamo due specie molto simili che devono essere rispettate anche se solo una è presente tra le specie protette in Toscana. IL GENERE ANEMONE Famiglia Ranunculaceae Anemone L. fu classificato da Linneo nel 1753. Il nome generico Anemone deriva dal latino ănĕmōnē, es termine usato da Plinio il Vecchio, a sua volta derivato dal greco άνεμώνη che denominava queste piante. Il termine è legato, nella tradizione popolare, a άνεμος (= vento) essendo questa pianta diffusa nei boschi esposti ai venti oppure perchè il suo fiore si apre al soffio dei venti. In realtà gli studiosi sono incerti sulla reale origine del termine che alcuni fanno derivare da Naaman, nome semitico di Adone, dal cui sangue, secondo la leggenda, si formarono gli anemoni. Diversi sono i miti che riguardano questo fiore: in uno di essi Zefiro si innamorò della ninfa Anemone e Chloris, la dea dei fiori, gelosa, la trasformò nel fiore condannato a schiudersi al soffio dei venti. In un altro mito Adone,del quale si era innamorata Venere, venne ucciso dal gelosissimo Marte trasformatosi in cinghiale, dalle lacrime di Venere e dal sangue di Adone sbocciarono gli anemoni. L’anemone era considerato simbolo di malinconia e dolore e in alcune tradizioni divenne simbolo del lutto e della morte Il genere Anemone è strettamente imparentato con i generi Pulsatilla e Hepatica tanto che in passato essi erano compresi nello stesso genere. -
Thomas Raus the Boreal and Centrai European Element in the Forest Flora
Thomas Raus The boreal and centrai European element in the forest flora of Greece Abstract Raus, T.: The boreal and centraI European element in the forest flora of Greece. - Bocconea 5: 63-76. 1995. - ISSN 1120-4060. The southemmost occurrences in Greece of selected vascular plant species associated with woodlands of beech, fir and spruce in C. and N. Europe are discussed. Preliminary maps of the Greek distribution are given for Aegopodium podagraria, Allium ursinum, Corallorhiza trifida, Galium odoratum, Lamium galeobdolon, Luzula luzuloides, L. sylvatica, Milium effusum, Orthilia secunda, Paris quadrifolia, Prenanthes purpurea, and Salvia glutinosa. Introduction The land surfaee of eontinental Greeee is far from being isolated from adjaeent parts of S.E. Europe by effeetive, W.-E. orientated geomorphologieal barriers. Mountains, lowlands and N.-S. running stream valleys allow free exehange and migration of organ isms from and to non-mediterranean areas in the north. The dinarie-pindie high moun tain system, in partieular, forrns an uninterrupted eonneetion between the southern part of the Balkan peninsula and C. Europe, whieh was an important faetor during the period of postglaeial restoration of European forest vegetation (Hammen 1965, Messerli 1967, Bottema 1974, Horvat & al. 1974, Athanasiadis 1975, Pott 1992). The mediterranean type climate, however, aetually limits regional southward distribution in N. and C. Greeee for many plants whieh are widespread in c., W. and N. Europe but not adapted to pronouneed summer aridity. Montane Fagus-Abies-Picea woodlands and various types of wetland habitats are those favourable niehes in Greeee where summer draught is suffieiently eompensated by miero- and mesoclimatie effeets and where most of the "northern" elements of the Greek flora are therefore eoneentrated. -

Vegetation dynamics and restoration trials in limestone quarries: the Botticino case study (Brescia, Italy) Federica Gilardelli UNIVERSITÀ DEGLI STUDI DI MILANO – BICOCCA Facoltà di Scienze Matematiche, Fisiche e Naturali Vegetation dynamics and restoration trials in limestone quarries: the Botticino case study (Brescia, Italy) Federica Gilardelli PhD thesis in Environmental Science XXV cycle Tutor: Cotutors: Prof. Sandra Citterio Prof. Sergio Sgorbati Dr. Rodolfo Gentili Dr. Stefano Armiraglio Collaborations: Dr. Ing. Sergio Savoldi Dr. Pierangelo Barossi February 2013 To all the quarrymen and their families. A tutti i cavatori e le loro famiglie. Background. All over the world, the naturalistic restoration of abandoned quarry areas represents a real challenge because of the very adverse initial site conditions for plant species colonization. In order to identify the best restoration practices, the present thesis considered, as a case study, the “Botticino extractive basin” (Lombardy, Italy), that is today the second greatest Italian extractive basin and it is famous worldwide for the limestone extraction. In particular, the thesis proposes a multidisciplinary approach based on the study of the local vegetation dynamics, laboratory tests, plant selection for restoration and field experiments to test different restoration techniques. Methods. Spontaneous vegetation dynamics over the whole extractive basin was studied by an ecological approach through 108 plots, that were carried out on surfaces whose “disused time” from quarry abandonment was known; data were analysed by cluster analysis and Canonical Correspondence Analysis (CCA) and compared to the available data on grassland and woodlands related to the study area. We identified successional phases according to the trend of the most common species whose cover significantly increases or decreases with time. -

Since 1982 when the last review of the genus was published by Brian Mathew many new taxa were found and work dealing with special parameters of Crocus, like the Calcium-oxalate crystals in the corm tunics, were published. Introducing molecular-systematic analyses to the genus brought a completely new understanding of Crocus that presents itself now far away from being small and easy-structured. This work was initiated by the idea that a detailed study accompanied by drawings and photographs is necessary to widen and sharpen the view for the important details of the genus. Therefore we look at the life-cycle of the plants as well as at important morphological and phenotypical characteristics of Crocus. Especially important to us is the explained determination of relevant taxonomical parameters which are necessary for a mistake-free identification of the rapidly increasing numbers of discovered species and for the creation of determination keys. Zusammenfassung: Die Gattung Crocus wird seit mehr als 30 Jahren von den Autoren sowohl in der Natur als auch in Kultur studiert. -

The Features of Lime Stands on Permanent Research Plots in Leningrad Region
FORESTRY AND WOOD PROCESSING DOI: 10.22616/rrd.24.2018.003 THE FEATURES OF LIME STANDS ON PERMANENT RESEARCH PLOTS IN LENINGRAD REGION Alexander Dobrovolsky, Oleg Antonov Saint Petersburg State Forest Technical University, Russia [email protected]; [email protected] Abstract The objects of research are the lime-tree forests of the Leningrad region. The studies were carried out on 2 permanent plots established by the authors in May 2013 in the Lisino forest district (Leningrad region, Russia). The goal of research was to obtain a complex characteristic of stands dominated by linden (Tilia cordata). The objective of the research included a taxation and geobotanical description on permanent plots and studies of the soil cover (morphological and agrochemical characteristics of soils). The general health status of stands on the surveyed areas was determined as satisfactory – mean score 2.5 and 2.8 (relevant health status was determined with the help of the following 6-grade scale for each tree: 1 – no signs of weakening; 2 – weakened tree; 3 – very weakened tree; 4 – partial mortality of the tree; 5 – dead-standing trees of the current year; 6 – dead-standing trees of previous years). The average mortality rate varies from 3.05% year-1 on the sample plot 2 to 5.7% year-1 on the sample plot 1. Vegetation on sample plots attributes to a nemorose-herbal series of forest types, soils – to a podzolic type with a weak development of the podzol-forming process. They were well-mediated ones by humus in the upper horizon. This fact was facilitated by the lime litter: a lime has a deep root system to take up nutritional chemicals from a greater depth, where moraine loams enriched with calcium carbonate located. -

Festuca Altissima All
Festuca altissima All. Wood Fescue Festuca altissima differs from most other Festuca species (unlike the allied genus Schedonorus) in being a tall broad-leaved grass. It has a scattered distribution from Bristol to northern Scotland, with concentrations in the Lake District, Tyne catchment and Glasgow area. It is evergreen and can be recorded throughout the year, flowering from mid- summer. Most sites are humid, being close to flowing water in crevices of shady rocks in gorges and denes. Previously under-recorded, its distinctive appearance is now better known, but it seems to be in rapid decline in some districts despite being considered as of ‘least concern’. ©John Richards IDENTIFICATION more; and Brachypodium sylvaticum which is also paler and more drooping, and is a smaller plant.

Salix L.) in the European Alps
diversity Review The Evolutionary History, Diversity, and Ecology of Willows (Salix L.) in the European Alps Natascha D. Wagner 1 , Li He 2 and Elvira Hörandl 1,* 1 Department of Systematics, Biodiversity and Evolution of Plants (with Herbarium), University of Goettingen, Untere Karspüle 2, 37073 Göttingen, Germany; [email protected] 2 College of Forestry, Fujian Agriculture and Forestry University, Fuzhou 350002, China; [email protected] * Correspondence: [email protected] Abstract: The genus Salix (willows), with 33 species, represents the most diverse genus of woody plants in the European Alps. Many species dominate subalpine and alpine types of vegetation. Despite a long history of research on willows, the evolutionary and ecological factors for this species richness are poorly known. Here we will review recent progress in research on phylogenetic relation- ships, evolution, ecology, and speciation in alpine willows. Phylogenomic reconstructions suggest multiple colonization of the Alps, probably from the late Miocene onward, and reject hypotheses of a single radiation. Relatives occur in the Arctic and in temperate Eurasia. Most species are widespread in the European mountain systems or in the European lowlands. Within the Alps, species differ eco- logically according to different elevational zones and habitat preferences. Homoploid hybridization is a frequent process in willows and happens mostly after climatic fluctuations and secondary contact. Breakdown of the ecological crossing barriers of species is followed by introgressive hybridization. Polyploidy is an important speciation mechanism, as 40% of species are polyploid, including the four endemic species of the Alps. Phylogenomic data suggest an allopolyploid origin for all taxa analyzed Citation: Wagner, N.D.; He, L.; so far. -
