Βασικός στόχος της διατριβής είναι η καταγραφή της ιθαγενούς και επιγενούς χλωρίδας της Καλύμνου, καθώς και η φυτοκοινωνιολογική μελέτη και καταγραφή των μονάδων βλάστησης του νησιού.H χλωρίδα της Καλύμνου αποτελείται από 831 taxa, 242 από τα οποία αναφέρονται για πρώτη φορά από το νησί. Το Linum grandiflorum Desf. αναφέρεται ως νέο επιγενές για την Ελλάδα. Πολυπληθέστερη οικογένεια είναι τα Leguminosae. Στο βιοφάσμα της Καλύμνου υπερέχουν τα θερόφυτα, ενώ στο χωρολογικό φάσμα τα Μεσογειακά γεωστοιχεία, από τα οποία σημαντική παρουσία έχουν τα Ανατολικομεσογειακά γεωστοιχεία. Στο χωρολογικό φάσμα της επιγενούς χλωρίδας, η οποία περιλαμβάνει 61 taxa, υπερτερούν τα Αμερικανικά γεωστοιχεία. Έπειτα από σύγκριση της χλωρίδας της Καλύμνου με τη χλωρίδα γειτονικών νησιών, με χρήση του δείκτη ομοιότητας του Sørensen, προκύπτει ότι η Κάλυμνος παρουσιάζει τη μεγαλύτερη χλωριδική συγγένεια με την Κω και τη Ρόδο. Στη χλωρίδα της Καλύμνου περιλαμβάνονται 17 ελληνικά ενδημικά taxa, 5 από τα οποία είναι τοπικά ενδημικά του Ανατολικού Αιγαίου. Από το σύνολο της χλωρίδας, 54 taxa περιλαμβάνονται σε εθνικούς και διεθνείς καταλόγους σπάνιων και απειλούμενων φυτών. Σύμφωνα με παρατηρήσεις μας, τρία taxa αμμόφιλης βλάστησης, με σημαντικότερο το Pancratium maritimum L., απειλούνται με εξαφάνιση από το νησί.Η βλάστηση μελετήθηκε με χρήση της μεθόδου Braun-Blanquet. Συνολικά πραγματοποιήθηκαν 152 φυτοληψίες. Tα αποτελέσματα της φυτοκοινωνιολογική έρευνας δείχνουν ότι η βλάστηση της Καλύμνου εντάσσεται σε 10 κλάσεις (Quercetea ilicis, Cisto-Micromerietea julianae, Crithmo-Staticetea, Saginetea maritimae, Cakiletea maritimae, Asplenietea trichomanis, Nerio-Tamaricetea, Thero-Brachypodietea ramosi, Stellarietea mediae και Isoeto-Nano-Juncetea). Στις 7 πρώτες αναγνωρίστηκαν συνολικά 9 τάξεις, 10 ενώσεις, 7 φυτοκοινωνίες και μία υποφυτοκοινωνία, καθώς επίσης και 16 φυτοκοινότητες, οι οποίες δε φαίνεται να αντιστοιχούν σε γνωστές από τη βιβλιογραφία φυτοκοινωνίες. Κάποιοι από τους τύπους βλάστησης που εντοπίστηκαν στην Κάλυμνο είναι σπάνιοι στο νησί, ενώ αρκετοί εμφανίζονται ιδιαίτερα υποβαθμισμένοι, κυρίως λόγω ανθρωπίνων δραστηριοτήτων.

The museum-preserve «The Kulikovo Field» is situated in the northern part of the Central Russian Upland within the forest-steppe zone near its northern border. There are a lot of abandoned fields, most of them left fallow since 1990–2000 years; the exact age of the old fields is unknown. Using the Braun-Blanquet approach as well as the method of K. Kopecký and S. Hejný (Kopecký, Hejný, 1974; Kopecký, 1992), the classification of the old-field vegetation of the central part of the museum-preserve was carried out. One derivate community, 2 basal communities (one of them with two variants), 3 communities and one association with three variants have been identified. The derivate community Conyza canadensis [Artemisietea vulgaris/Stellarietea mediae] is dominated by annual and biennial ruderal species: Conyza canadensis, Lactuca serriola and Carduus acanthoides. The association Convolvulo arvensis–Elytrigietum repentis is heterogeneous both in its floristic and subdominant composition and it can be divided into 3 variants. The variant typica represents monodominant communities where Elytrigia repens prevails. The variant Lactuca serriola is characterized by high constancy of Conyza canadensis, Lactuca serriola and some other ruderal plants and it represents coenoses dominated by Elytrigia repens with subdominants such as Lactuca serriola, Senecio jacobaea and Pilosella spp., mainly P. bauhini. The variant Cichorium intybus is dominated by Elytrigia repens with a subdominant Cichorium intybus; some mesophilous meadow species are often present. Variants Melilotus officinalis and Sonchus arvensis of the basal communityElytrigia repens–Cichorium intybus [Artemisietea vulgaris] are dominated by Cichorium intybus, Poa angustifolia and Elytrigia repens, the first of them also by Melilotus officinalis, Artemisia absinthium, and the second by Carduus acanthoides and Calamagrostis epigeios. Unlike the foregoing syntaxa the basal community Elytrigia repens–Cichorium intybus [Artemisietea vulgaris] is characterized by relative high constancy of some species pertaining to the order Galietalia veri, namely Fragaria viridis, Galium verum, Potentilla argentea. These species and also Poa angustifolia are the first steppificated meadow plants that appear in the old field communities under investigation. The community Pilosella bauhini [Onopordion acanthii] is dominated by Pilosella spp., mainly by P. bauhini that sometimes replaced by some ruderal plants, e. g. Achillea nobilis or Cichorium intybus. The peculiarity of this community is the low constancy and abundance of Elytrigia repens. The species of the orders Galietalia veri and Arrhenatheretalia play much noticeable role in the other syntaxa mentioned below, so these syntaxa are between the natural and synanthropic vegetation. The community Leucanthemum vulgare–Galium mollugo [Onopordion acanthii/Molinio-Arrhenatheretea] is distinguished by high abundance and constancy of some mesophilous and xeromesophilous meadow plants (Leucanthemum vulgare, Galium mollugo, Phleum pratense etc.). The community Artemisia marschalliana [Onopordion acanthii/Galietalia veri] is dominated mostly by Leontodon hispidus and Pilosella spp.; its peculiarity is a relatively high constancy of species common in the local steppificated meadows. The basal community Poa angustifolia [Galietalia veri/Artemisietea vulgaris] represents monodominant communities where Poa angustifolia prevails. Annual, biennial and some perennial ruderal species are rare in this variant, unlike most of the syntaxa mentioned above. The common feature of the last three syntaxa is subdominance of Fragaria viridis. It is known that the floristic composition of communities is changed during an old-field succession: the percentage of annual and biennial species declines and that of species pertaining to the classes of natural vegetation increases (Bonet, Pausas, 2007; Yamalov et al., 2008; Pankratova, Gannibal, 2009). Using the life-form and phytosociological spectrum of the syntaxa analysis an attempt to evaluate succession status of the described communities was made (tab. 9, 10). Based upon the results of this analysis, it is possible to suggest that the derivate community Conyza canadensis [Artemisietea vulgaris/Stellarietea mediae] is the earliest stage one can find in the investigated old fields. The variants Lactuca serriola and typica of the association Convolvulo arvensis–Elytrigietum repentis and the community Pilosella bauhini [Onopordion acanthii] are the next in the series. It seems that Pilosella spp. (P. bauhini and probably some other species of this genus) outcompete the pioneer species of initial stages, like Elytrigia repens, in some cases. The basal community Poa angustifolia [Galietalia veri / Artemisietea vulgaris] seems to be the most advanced stage: the percentage of annuals and biennials is minimal, and that of species pertaining to the syntaxa of natural vegetation of the high ranks, especially to the order Galietalia veri, increases greatly. Species richness of the communities is minimal at the most early stage, which is the peculiarity of the old-field vegetation (Pankratova, Gannibal, 2009; Ovcharova, Yamalov, 2013). Similar phenomenon was also noticed at the succession stages where strong dominant (Elytrigia repens or Poa angustifolia) prevails, regardless of how much advanced these stages are, the fact mentioned earlier (Prach, 1985). Species richness attains maximum at those stages of succession where the communities are polydominant and contain both early- and late-successional species, that was also previously described (Meiners et al., 2007).

Pancratium Maritimum

Pancratium maritimum (Amaryllidaceae) is a bulbous geophyte growing on coastal sands. In this study, we investigated changes in concentrations of metabolites in the root and leaf tissue of P. maritimum in response to mild salt stress. Changes in concentrations of osmolytes, glutathione, sodium, mineral nutrients, enzymes, and other compounds in the leaves and roots were measured at 0, 3, and 10 days during a 10-day exposure to two levels of mild salt stress, 50 mM NaCl or 100 mM NaCl in sandy soil from where the plants were collected in dunes near Cuma, Italy. Sodium accumulated in the roots, and relatively little was translocated to the leaves. At both concentrations of NaCl, higher values of the concentrations of oxidized glutathione disulfide (GSSG), compared to reduced glutathione (GSH), in roots and leaves were associated with salt tolerance. The concentration of proline increased more in the leaves than in the roots, and glycine betaine increased in both roots and leaves. Differences in the accumulation of organic osmolytes and electron donors synthesized in both leaves and roots demonstrate that osmoregulatory and electrical responses occur in these organs of P. maritimum under mild salt stress.

AbstractThe work deals with vegetation zonation in temporary ponds within cold holes in the Western Taurus mountain chain. There are two main factors that cause differentiation within the studied vegetation: one relates to the microtopography, the other to altitude. In the bottom of temporary ponds, marsh vegetation of Ranunculo argyrei-Tanacetea argentei (Sedo nani-Convolvuletalia galactici) appears (an endemic class vicariant to Scheuchzerio-Caricetea fuscae); in the intermediate zone, the vegetation is dominated by therophytes of Stellarietea mediae (Thero-Brometalia) and in the upper part, there is vegetation of hygrophilous grassland communities of Molinio-Arrhenatheretea (Potentillo-Polygonetalia). This zonation of communities can be found at lower altitudes (up to 1600 m); whereas at higher altitudes, the intermediate zone dominated by therophytes gradually disappears and then also the hygrophilous grasslands. The work also provides a description of new syntaxa, to wit: Ranunculo argyrei-Tanacetea argentei, Sedo nani-Convolvuletalia galactici, Rorippo aureae-Eleocharidion quinqueflorae, Sedo nani-Ranunculetum argyrei, Trifolio caudati-Hordeion geniculati, Taeniathero caput-medusae-Hordeetum geniculati, Alopecuro vaginati-Trifolion resupinati and Ornithogalo lanceolati-Elymetum repentis.

Stellarietea Mediae

Neste estudo apresenta-se uma classificação fitossociológica com base em inventários próprios realizados, de acordo com a metodologia fitossociológica, em comunidades herbáceas vivazes e anuais, nas subprovíncias Luso-Estremadurense, Carpetana-Leonesa e Orolusitana Atlântica, abrangendo o SE & CE de Portugal continental. O objetivo principal é a descrição das comunidades herbáceas do ponto de vista da composição e variabilidade florística, da ecologia, da distribuição e abundância na área de estudo, da sintaxonomia, dos contactos catenais, da sindinâmica e do estatuto de conservação, tendo como base os dados recolhidos no campo e obtidos através de pesquisa bibliográfica. Foram identificadas 9 classes de vegetação herbácea, 3 classes de vegetação arbustiva, 3 classes de vegetação arbórea e 65 associações no total. Assim, as comunidades inventariadas distribuem-se pelas classes: Isoeto-Nanojuncetea; Magnocarici elatae-Phragmitetea australis; Stellarietea mediae; Tuberarietea guttatae; Poetea bulbosae; Festuco-Brometea; Lygeo-Stipetea; Stipo giganteae-Agrostietea castellanae e Molinio-Arrhenatheretea. Foram identificadas 14 ordens, 20 alianças, 43 associações e 7 subassociações, no conjunto das comunidades terofíticas e vivazes estudadas, desde biótopos oligotróficos, nitrófilos e higrófilos a mesofíticos. Obtiveram-se 12 sintaxa que correspondem a habitats da Diretiva Habitats, alguns dos quais prioritários para conservação. É apresentada uma aproximação a um modelo dinâmico-catenal no qual se identificam os padrões de resposta das comunidades herbáceas a vários fatores de perturbação. Conclui-se que o conhecimento obtido a partir da Geobotânica, nomeadamente da Sinfitossociologia, constitui uma ferramenta essencial para uma gestão sustentável do território.
