Vegetation and Phytodiversity Analysis, Untere Karspüle 2, 37073 Göttingen, Germany; [email protected], [email protected] Keywords: Relict species, Species distribution modelling, Ecological niche, Genetic isolation, Metapopulation, Plant conservation, Crete. Abstract Mediterranean mountain forests feature woody species relicts such as Zelkova abelicea, an endemic tree species confined to six spatially and genetically distinct populations in Crete (S Aegean, Greece). We used species distribution modelling to predict the potential distribution of Zelkova abelicea. Comparison of coordinate-based geodata extractions for climate and topography revealed pronounced environmental differences for the metapopulations. Main factors for species distribution models were altitude and temperature seasonality (proxy for west-east gradient) whereas topographic conditions had surpris- ingly little influence on our models. While the most extensive Zelkova metapopulations were found to occur under locally fairly mesic conditions and comprising a wider ecological spectrum, the smaller populations comprising narrower ecological range occurred at lower elevations and further east. For further extrapolation with similar models for known populations, only similar site conditions allowed for a prediction. Differentiated site conditions in the mountains, genetic distinctness and possible environmental adaptations of isolated populations are to be considered in conservation and management.

The Macrobotanical Evidence for Vegetation in the Near East, c. 18 000/16 000 B.C to 4 000 B.C. Abstract Vegetation during the glacial period, post-glacial warming and the Younger Dryas does not seem to have been affected by human activities to any appreciable extent. Forest expansion at the beginning of the Holocene occurred independently of human agency, though early Neolithic farmers were able to take advantage of improved climatic conditions. Absence of macrobotanical remains precludes discussion of possible drought from 6,000 to 5,500 ВС. By farming, herding, and fuel-cutting, human populations began to have an impact on the landscape at different times and places. Deleterious effects of these activities became evident in the Tigris-Euphrates drainage during the third millennium ВС based on macrobotanical evidence from archaeological sites. -
Vascular Plant Species Diversity of Mt. Etna
Vascular plant species diversity of Mt. Etna (Sicily): endemicity, insularity and spatial patterns along the altitudinal gradient of the highest active volcano in Europe Saverio Sciandrello*, Pietro Minissale* and Gianpietro Giusso del Galdo* Department of Biological, Geological and Environmental Sciences, University of Catania, Catania, Italy * These authors contributed equally to this work. ABSTRACT Background. Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt. Etna, the highest active volcano in Europe. Methods. We used all the available data (literature, herbarium and seed collections), plus hundreds of original (G Giusso, P Minissale, S Sciandrello, pers. obs., 2010–2020) on the occurrence of the Etna plant species. Mt. Etna (highest peak at 3,328 mt a.s.l.) was divided into 33 belts 100 m wide and the species richness of each altitudinal range was calculated as the total number of species per interval. In order to identify areas with high plant conservation priority, 29 narrow endemic species (EE) were investigated through hot spot analysis using the ``Optimized Hot Spot Analysis'' tool available in the ESRI ArcGIS software package. Results. Overall against a floristic richness of about 1,055 taxa, 92 taxa are endemic, Submitted 7 November 2019 of which 29 taxa are exclusive (EE) of Mt. -

Flora and Vegetation The southern part of Herzegovina where is situated the alignment is distinguished by the presence of mainly evergreen vegetation with numerous typical Mediterranean plants and rich fauna. 1.1. Flora The largest number of plant species belongs to the various subgroups of Mediterranean floral element. The most abundant plant families are grasses (Poaceae), legumes (Fabaceae) and aster family (Asteraceae), which also indicates Mediterranean and Submediterranean features of the flora. After literature data (Šilić 1996), some 10% of rare, endangered and endemic plant species from Bosnia and Herzegovina grows in Mediterranean region of the country. From this list, in investigated area could be found vulnerable species Celtis tournefortii, Cyclamen neapolitanum, Cyclamen repandum, Acanthus spinossisimus, Ruscus aculeatus, Galanthus nivalis, Orchis simia, Orchis spitzelii and some others. Rare species in this area are: Dittrichia viscosa, Rhamnus intermedius, Petteria ramentacea, Moltkia petraea, and Asphodelus aestivus. By the roads and in the areas under strong human impacts could be found certain introduced species, such as Paspalum paspaloides, P. -
Rare Indigenous Sheep Breeds of Greece Kominakis, A
Rare indigenous sheep breeds of Greece Kominakis, A. and E. Rogdakis Department of Animal Breeding & Husbandry, Agricultural University of Athens (AUA), Iera Odos 75, 11855, Athens, Greece, tel. +30-2105294403, fax +30-2105294442, e-mail: [email protected] Of the 6400 documented farm animal breeds, about one third is threatened by extinction (Scherf, 2000). Unlike in general biology, the focus in farm animal biodiversity is not on species, but on breeds within species. While species are clearly defined, breeds are not. Some definitions are based on arguments from population genetics while others also include sociological and cultural considerations. An exhaustive survey, lasted over 3 years, was undertaken by the Department of Animal Breeding & Husbandry of AUA, in an attempt to identify and describe the rare indigenous sheep breeds of Greece. According to this study, there were totally 17 sheep breeds identified. In terms of census population size, the status of these indigenous sheep populations could be characterized as critical i.e. close to extinction (N<300), endangered (300<N<1000), vulnerable (N=1,000-5,000) or insecure (N=5,000- 10,000) (Bodo, 1989, modified). It should be, however, noted that these are general guidelines; knowledge of the effective population size (Ne) is more important because it is directly associated with the genetic variation of a population. In breeding populations, Ne can be dramatically smaller than the census one because it is strongly affected by the ratio of males to females, selection and non random mating. The major morphological and (re)production characteristics of the 17 rare sheep breeds are presented in Table 1. -

Die gemessenen Spaltspuralter und modellierten Abkühlpfade weisen auf regionale und zeitliche Schwankungen der posteozänen Abtragungsgeschwindigkeiten hin. Zwei präeozäne Generationen von Paläokarst sind auf Skopelos zu beobachten. Die erste entwickelte sich während der Unterkreide auf triadischen Dolomiten des alten pelagonischen Schelfs. Die Bauxite und Laterite, mit denen dieser Palaeokarst versiegelt ist, sind aus verschwemmtem Material der Eohellenischen Decke hervorgegangen. Eine zweite Generation von Paläokarst entwickelte sich auf oberkretazi- schen Rudistenkalken und wurde unter palaeogenem Flysch begraben. Drei Generationen neogener Verflachungen treten auf Skopelos oberhalb von 300 m Seehöhe auf. -

MIRKOU (With 7 textfigures) Manuscript received on 17th of March 1980 Zusammenfassung Auf der Insel Paros bildet die Molasse die höchste Formation der Marmara-Decke. Diese ist ein Teil der regionalen Kykladen-Decke und umfaßt alle vorobermiozänen, nichtmetamorphen Gesteine des Gebietes. Das Alter der Molasse und ihrer Transgression auf den Ophiolithen wurde mit Foraminiferen und kalkigem Nannoplankton als Burdiga- lien bestimmt. Daraus ergibt sich eine Platznahme der Kykladen-Decke in der Zeit nach dem Burgidalien und vor dem Messinien, da die frühesten autochthonen Sedimente auf Milos dieses Alter haben. Die Kykladen-Decke stammt wahrscheinlich aus einem Gebiet südlich der Kykladen, etwa aus dem jetzigen Kreta-Becken. Abstract The Molasse of Paros Island is the upper formation of Marmara nappe, which is part of the regional Cycladic nappe comprising all the pre-upper Miocene non-metamorphic rocks of the area. The age of the Molasse as well as of its transgression on the ophiolites was determined by foraminifera and calcareous nannoplankton as Burdigalian. Hence, the emplacement of the Cycladic nappe is of post-Burdigalian and of pre-Messinian age (from the age of the first autochthonous sediments of Milos). -
Hyrcanian Vegetation
Plant Formations in the Hyrcanian BioProvince Peter Martin Rhind Hyrcanian Alnus-Pterocarya Forest These ancient yet ill-defined forests are confined mostly to damp and poorly drained soils on the coastal plain. They are characterized by the near endemic Alnus subcordata (Betulaceae) and Pterocarya fraxinifolia (Juglandaceae). Common associates include Acer insigne, Albizia julibrissin, Alnus glutinosa, Buxus sempervirens, Celtis australis, Diospyros lotus, Ficus carica, Fraxinus excelsior, Melia azedarach, Mesilus germanica, Morus nigra, Paliurus spina-christa, Prunus laurocerasus, Punica granatum and Salix fragilis, while common endemic or near endemic species are Gleditsia caspica (Fabaceae), Populus caspica (Salicaceae), and Prunus caspica (Rosaceae). The shrub layer comprises Andrache colchica, Hypericum androsaemum, Sambucus edulis and several endemic taxa like Epimedium pinnatum subsp. pinnatum (Berberidaceae), Ruscus hyrcanus (Liliaceae) and Teucrium hyrcanus (Lamiaceae). These forests are also characterised by the presence of numerous lianas and climbers, which occur on many of the trees and shrubs - typical species are Clematis vitalba, Hedera colchica, Jasminum officinale, Peroploca graeca, Rubus caesius, Smilax excelsa, Solanum dulcamara, Tamus communis and Vitis sylvestris. Hyrcanian Zelkova-Parrotia Forest These forests, dominated by Zelkova carpinifolia and the near endemic Parrotia persica (Brassicaceae), are primarily confined to the foothills and lower mountain slopes up to about 800 m. For a long time Parrotia was thought -
Ground Deformation Modelling of the 2020 Mw6.9 Samos Earthquake (Greece) Based on Insar and GNSS Data
remote sensing Article Ground Deformation Modelling of the 2020 Mw6.9 Samos Earthquake (Greece) Based on InSAR and GNSS Data Vassilis Sakkas Department of Geophysics-Geothermics, National Kapodistrian University of Athens, Panepistimiopolis Zografou, 15784 Athens, Greece; [email protected]; Tel.: +30-2107274914 Abstract: Modelling of combined Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) data was performed to characterize the source of the Mw6.9 earthquake that occurred to the north of Samos Island (Aegean Sea) on 30 October 2020. Pre-seismic analysis revealed an NNE–SSW extensional regime with normal faults along an E–W direction. Co- seismic analysis showed opening of the epicentral region with horizontal and vertical displacements of ~350 mm and ~90 mm, respectively. Line-of-sight (LOS) interferometric vectors were geodetically corrected using the GNSS data and decomposed into E–W and vertical displacement components. Compiled interferometric maps reveal that relatively large ground displacements had occurred in the western part of Samos but had attenuated towards the eastern and southern parts. Alternating motions occurred along and across the main geotectonic units of the island. The best-fit fault model has a two-segment listric fault plane (average slip 1.76 m) of normal type that lies adjacent to the northern coastline of Samos. This fault plane is 35 km long, extends to 15 km depth, and dips to the north at 60◦ and 40◦ angles for the upper and lower parts, respectively. A predominant dip-slip component and a substantial lateral one were modelled. Citation: Sakkas, V.

Abstract A work on the Celtis tournefortii subsp. aetnensis vegetation, endemic species located in disjointed sites in the Sicilian inland, is here presented. It forms microwoods with a relict character established on screes and detrital coverages, on a variety of lithological substrates (volcanics, limestones, quartzarenites). Based on the phytosociological analysis carried out in the territory, these vegetation aspects are framed in the alliance Oleo-Cerato- nion, within which a new association (Pistacio terebinthi-Celtidetum aetnensis) is described, in turn diversified in the following subassociations: a) typicum subass. nova, on detrital calcareous cones of the north-western part of Sicily, in the Palermo province (Rocca Busambra, Pizzo Castelluzzo and northern slopes of Pizzo Telegrafo); b) phlomidetosum fruticosae subass. nova, typical of carbonate megabreccias, on the most xeric sou- thern slopes of Pizzo Telegrafo (Caltabellotta territory, Agrigento province); c) artemisietosum arborescentis subass. nova, typical of quartza- renitic outcrops on the Nebrodi Mts. inland (Cesarò territory, Messina province); d) rhamnetosum alaterni subass. nova, widespread on cracked lava flows of the western side of Mount Etna (Catania province).
