The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges. -

SUMMARY In Chile’s Mediterranean region, over 18% of plant species are alien. This is particularly noteworthy in some agrosilvopastoral systems such as the espinales, which are functionally very similar to the Spanish dehesas and are of great ecological and socioeconomic interest. In the present paper we analyse Chile’s non-native flora, considering three scales of analysis: national, regional (the central region, presenting a Mediterranean climate) and at community level (the espinales within the central region). We compare this flora with that recorded in areas of the Iberian Peninsula with similar lithological and geomorphological characteristics, and land use. We discuss possible mechanisms that might have been operating in the floristic colonisation from the Mediterranean Basin to Chile’s Mediterranean region. Key words: Alien plants, biogeography, Chile, life cycle, Spain. INTRODUCTION Historically, the transit of goods, domestic animals and people has favoured the flow of wild organisms around the planet (Lodge et al., 2006), a fact that is often associated with the introduction of cultural systems, which have contributed to generating new environmental and socioeconomic scenarios (Le Houérou, 1981; Hobbs, 1998; Grenon and Batisse, 1989). -
Eastern Anatolia
A general survey of the vegetation of north - eastern anatolia by İBRAHİM AT AL AY Introduction The study area named NE Anatolia which is bounded by the Erzurum-Rize line on the west, the Erzurum-Tuzluca line or the Aras river valley on the south, comprises the subregion of the Eastern Black Sea and the subregion of Erzurum- Kars in Eastern Anatolia. From the vegetational point of view, the lower part of the Eastern Black Sea Mountains was covered by broad-leaved forests, and the upper section was occupied by pine forests. The southern slopes of the East Black Sea Mountains were covered by xerophytic and winter hardy forest from the bottom to the upper section, while the slopes facing the north of the ranges were covered by winter hardy and humid forests such as spurce, fir and Scotch pine. The upper watershed areas of the Çoruh river basin were occupied by oak, juniper, and shrub formations. The northern slopes and upper part of the continental sector of Eastern Ana tolia were occupied by scotch pine. Natural steppe vegetation was common on the tectonic corridor of the Aras valley, the Oltu basin, and the Kağızman-Tuzluca basin. Destroyed forest areas were covered by the mountain steppe which belong to the irano-Turanian ele ments. Tall prairie-like grass was seen between the Erzurum-Kars plateau. Alpine and subalpine grasses were widespread on the upper part of mountains. The aim of this short article is to explain the distribution of vegetation-for- mation and the evolution of vegetation and floristic composition in this region. -
Management of Threatened, High Conservation Value, Forest Hotspots Under Changing Fire Regimes
Chapter 11 Management of Threatened, High Conservation Value, Forest Hotspots Under Changing Fire Regimes Margarita Arianoutsou , Vittorio Leone , Daniel Moya , Raffaella Lovreglio , Pinelopi Delipetrou , and Jorge de las Heras 11.1 The Biodiversity Hotspots of the Earth Biodiversity hotspots are geographic areas that have high levels of species diversity but signifi cant habitat loss. The term was coined by Norman Myers to indicate areas of the globe which should be a conservation priority (Myers 1988 ) . A biodiversity hotspot can therefore be defi ned as a region with a high proportion of endemic species that has already lost a signifi cant part of its geographic original extent. Each hotspot is a biogeographic unit and features specifi c biota or communities. The current tally includes 34 hotspots (Fig. 11.1 ) where over half of the plant species and 42% of terrestrial vertebrate species are endemic. Such hotspots account for more than 60% of the world’s known plant, bird, mammal, reptile, and amphibian M.

Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -
Juniperus Thurifera
Juniperus thurifera Juniperus thurifera in Europe: distribution, habitat, usage and threats A. Gastón González, J. I. García-Viñas, S. Saura, G. Caudullo, D. de Rigo The Spanish juniper (Juniperus thurifera L.) is a small coniferous evergreen tree that forms open woodlands on poor soils with Mediterranean continental climate. Its natural range is the western part of the Mediterranean basin, mainly Spain, where is currently colonising new areas due to abandonment of arable lands. The Spanish juniper woodlands are protected habitats by European legislation. The Spanish juniper (Juniperus thurifera L.) is an evergreen coniferous shrub or tree, which can grow up to 20 m1, but usually Frequency has a height of 5-12 m. The crown is pyramidal in youth and < 25% then it becomes broad, rounded, and often irregular. The bark is 25% - 50% 50% - 75% thin, dark brown, grey-brown at maturity, scaly and exfoliating in > 75% strips. Leaves are light green, 2 mm long, acute scaly, appressed, Chorology Native covering completely the twigs. This tree species is dioecious. Flowers in male trees are clustered in 3-4 mm yellow spherical cones. Female trees have almost undetectable flowers that ripen into 7-8 mm berry-like dark-purple fleshy cones2. Berry-like dark-blue seed cones: they mature over a period of around 18 months. Distribution (Copyright Gaston Aitor: CC-BY) The Spanish juniper is endemic to South-Western Europe and viable seeds9.

The aim of this study was to collect information on the prescribing habits of a sample of Italian dentists with respect to the role of antibiotic prophylaxis in preventing surgical site infections (SSI). An anonymous questionnaire was prepared and made accessible online by sharing a Google Forms link. General anagraphic data and educational background information were collected to obtain a profile of the participants. Different clinical scenarios were then proposed, with the participants asked to choose whether they would prescribe an antibiotic prophylaxis and with which dosage regimens. In total, 169 dentists participated in the questionnaire and the obtained data were assessed through a percentage report. The results showed a substantial agreement in antibiotics prescription, but only in a limited number of clinical scenarios, such as deciduous teeth extraction or simple extractions in healthy adult patients. Discordant responses were found for several clinical cases, particularly Citation: Lollobrigida, M.; Pingitore, G.; Lamazza, L.; Mazzucchi, G.; for cases of comorbidities, surgical or multiple extractions, implant placement and abscess drainage. -

The aim of this work is to evaluate the ecological status of Juniperus foetidissima Willd. forest stands in the protected Natura 2000 site of Mt. Oiti in Greece. The study of the ecological status is important for designing and implementing active management and conservation actions for the species’ protection. Tree size characteristics (height, breast height diameter), age, reproductive dynamics, seed production and viability, tree density, sex, and habitat expansion were examined. The data analysis revealed a generally good ecological status of the habitat with high plant diversity. However, at the different juniper stands, subpopulations present high variability and face different problems, such as poor tree density, reduced numbers of juvenile trees or poor seed production, inadequate male:female ratios, a small number of female trees, reduced numbers of seeds with viable embryos, competition with other woody species, grazing, and Citation: Proutsos, N.; Solomou, A.; illegal logging. From the results, the need for site-specific active management and interventions is Karetsos, G.; Tsagari, K.; Mantakas, demonstrated in order to preserve or achieve the good status of the habitat at all stands in the region. -
