The vegetation of the high mountains of Crete - a revision and multivariate analysis, 2002,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Bergmeier E,
The vegetation at elevations above 1,400 m in the south Aegean island of Crete (Greece) is studied and revised. By means of phytosociological classification (assisted by TWINSPAN) and ordination (Detrended correspondence analysis, DCA), the plant communities and abiotic (environmental, geographical) factors governing the variance in vegetation are described and discussed. The analyses are based on 492 sample plots from the three major mountain ranges of Crete. All published data available, as well as own unpublished releves are included. Since the plots differ much with respect to species number and plot size, and to combine different subsets and different data properties, various data sets are used for DCA ordination. Data on environmental variables are used supplementarily. Ordination results suggest the following factors to be of major effect on the variance in vegetation: Rock type, soil type, altitude, geographical situation, degree of substrate fixation, and inclination. The representation of local and regional endemics in the vegetation increases with altitude and along the habitat type series: phrygana and woodland - fixed slopes - dolines - screes. A synoptic table of 26 columns (vegetation types and subtypes) is presented. The vegetation consists of the tragacanth formation of fixed slopes (8 columns), swards and scrub of doline grounds (9), scree vegetation (4), and rupicolous chasmophytic vegetation (2). Phrygana (2) and woodland vegetation (1) are marginal. A hierarchical conspectus of the syntaxa is provided which includes the following nomenclaturally relevant new or validated names of various ranks (in alphabetic order): Alysso sphaciotici-Valantion apricae, Arenario fragillimae-Silenetum antri-jovis, Arenarion creticae, Astragalion cretici, Berberido creticae-Astragaletum cretici, Cicero incisi-Silenetum variegatae, Colchico cretensis-Cirsion morinifolii, Fumano paphlagonicae-Helianthemetum hymettii, Gypsophilo nanae-Arenarietum creticae, Hyperico kelleri-Anchusetum cespitosae, Lomelosio sphacioticae-Centranthetum sieberi, Paronychio macrosepalae-Juniperetum oxycedri, Saturejo spinosae-Scutella-rietalia hirtae, Sideritido syriacae-Verbascetum spinosi, Verbascion spinosi

The vegetation of alpine belt karst-tectonic basins in the central Apennines (Italy), 2005,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/speleogenesis.info/include/functions1.php on line 943
Blasi C, Di Pietro R, Pelino G,
The vegetation communities of the karst-tectonic basins of the Majella massif alpine belt were studied using the phyto sociological methods, and analysed from coenological, synchorological and syntaxonomical viewpoints. During the field-work, 115 releves were performed using the phytosociological approach of Braun-Blanquet, and these releves were further subjected to multivariate analyses. Eight clusters of releves resulted from the numerical classification. The plant communities identified in the study area were ascribed to the following five associations, two sub-associations and one community type: Leontopodio - Seslerietum juncifoliae (ass. nova); Helianthemo - Festucetum italicae (ass. nova); Gnaphalio - Plantaginetum atratae; Taraxaco-Trifolietum thalii gnaphalietosum magellensis (subass. nova),- Luzulo italicae-Nardetum, Carici - Salicetum retusae; Saxifrago - Papaveretum julici, Saxifrago - Papaveretum androsacetosum (subass. nova), Plantago atrata and Leontodon montanus community. The distribution of these communities within the karst basins was found to be related to variations in topographic and geomorphological parameters, such as altitude, slope, soil availability and stoniness. All the new associations proposed in this paper belong to the suballiance Leontopodio-Elynenion and to the alliance Seslerion apenninae, both of which are endemic to the central Apennines. In order to compare the plant community types identified within the Majella massif to similar associations found in the rest of the Apennine chain, synoptic tables were constructed. Finally, a comparative phytogeographical analysis of the alpine belt vegetation of the Apennines, Dinarides, southern Balkans and eastern Alps is presented

Vascular plant biodiversity richness and endemo relictness of the karst mountains Prenj-Čvrsnica-Čabulja in Bosnia and Herzegovina (W. Balkan) , 2011,

The complex of karstic mountains Prenj-Čvrsnica and Čabulja in Herzegovina (w. Balkan) is characterized by high level of both geomorphology and biodiversity richness. This has been confirmed by a research of plant communities, their structure and dynamics, which took place throughout several seasons from 2005 to 2008. In the investigated area the vegetation cover, as a reliable indicator for specific karstic circumstances, is being differentiated in a great number of syntaxa (plant communities) that encompass over 2,500 vascular plants. On the surface of about 100,000 ha identified were up to 236 plant associations, 116 alliances and 63 vegetation orders that belong to 34 classes. This amounts 34% of total of vegetation classes at the European level and 100% of so far known vegetation classes in Bosnia and Herzegovina, over 80% of classes at the level of Montenegro and Croatia.There have been identified nearly 450 endemic and relict species, which is why most of the identified communities are endemic and relict ones, not only at the level of association but also at the level of higher syntaxonomic categories, such as alliance and order. The highest diversity level characterizes those communities that make a direct contact with the calcareous geological foundation either in rock crevices or screes on limestone. That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean.That high level of floristic and vegetation richness places this area among the most diverse areas both in Europe and whole Mediterranean. Such pattern of vegetation (syntaxonomy) and floristic diversity confirms the unique role of dinaric-herzegovina karst as a complex of unrepeatable ecological factors on global scale.
