Pre‐instrumental summer precipitation variability in northwestern Greece from a high‐elevation Pinus heldreichii network

2021

The spatiotemporal variability of precipitation is of vital importance to Mediterranean ecology and economy, but pre‐instrumental changes are not well understood. Here, we present a millennial‐length June–July precipitation reconstruction derived from a network of 22 Pinus heldreichii high‐elevation sites in the Pindus Mountains of northwestern Greece. Tree‐ring width chronologies from these sites cohere exceptionally well over the past several hundred years (r1467–2015 = 0.64) revealing coherence at inter‐annual to centennial timescales across the network. The network mean calibrates significantly against instrumental June–July precipitation over the past 40 years (r1976–2015 = 0.71), even…

Mapping traditional cultural landscapes in the Mediterranean area using a combined multidisciplinary approach: Method and application to Mount Etna (…

2011

Traditional cultural landscapes (TCLs) are prominent in Mediterranean countries. The abundance of this landscape type, however, is not reflected by broad-scale inventories and mapping tools. The aim of this paper is to highlight the need for a multidisciplinary approach to landscape analysis, with special reference to the Mediterranean area. We propose an integrated method that combines deductive and inductive processes to define and map TCLs in a study area (Mount Etna, Sicily, Italy). We also develop a procedure to characterize the primary components of these landscapes as a reference to be used in cultural-landscape descriptions. For mapping purposes, three different scales of analysis w…

Archaeology of Uplands on a Mediterranean Island. The Madonie Mountain Range In Sicily

2019

The book presents an archaeological research conducted within the Highlands of Sicily. Results of the archaeological survey in the Madonie mountain range, in northern Sicily, supported by a chronological and cultural grid, drawn by the excavation of Vallone Inferno, deal with complex and fascinating problems of uplands and mountainous landscape. Settlement patterns, between the Late Pleistocene and the Medieval era, are investigated through the support of spatial analyses. A diversified use of the mountain is currently attested by this research, according to the different prehistoric and historical times. This work is innovative for the Mediterranean area, where there are no similar example…

Four-year soil erosion rates in a running-mountain trail in eastern Iberian Peninsula

2019

During the last decades, the use of mountain trails for running is more and more popular. New trails are opened to allow the runners to practice and compete. This form of human impact on the landscape is new as the new trails do not follow the conservation strategies in design and maintenance as traditional mountain trails constructed by farmers, shepherds and muleteers do. This impact of sport events in nature is not measured and we know little about this impact on vegetation, fauna and soils. We surveyed in September 2018 a trail that was opened in September 2014 and was used for four official mountain trail races, and for training by local runners. Our interviews with organizers and user…

Statistical features and perceived similarity of folk melodies

2001

Listeners are sensitive to pitch distributional information in music (N. Oram & L. L. Cuddy, 1995; C. L. Krumhansl, J. Louhivuori, P.Toiviainen, T. Järvinen, & T. Eerola, 1999). However, it is uncertain whether frequency-based musical features are sufficient to explain the similarity judgments that underlie listeners' classification processes. A similarity rating experiment was designed to determine the effectiveness of these features in predicting listeners' similarity ratings. The material consisted of 15 melodies representing five folk music styles. A multiple regression analysis showed that the similarity of frequency-based musical properties could account for a moderate amount …

Domain Structures in Langmuir-Blodgett Films Investigated by Atomic Force Microscopy

1993

Investigations of phase-separated Langmuir-Blodgett films by atomic force microscopy reveal that on a scale of 30 to 200 micrometers, these images resemble those observed by fluorescence microscopy. Fine structures (less than 1 micrometer) within the stearic acid domains were observed, which cannot be seen by conventional optical microscopic techniques. By applying the force modulation technique, it was found that the elastic properties of the domains in the liquid condensed phase and grains observed within the liquid expanded phase were comparable. Small soft residues in the domains could also be detected. The influence of trace amounts of a fluorescence dye on the micromorphology of monol…

Observed versus simulated mountain waves over Scandinavia – improvement by enhanced model resolution?

2016

Abstract. Two mountain wave events, which occured over northern Scandinavia in December 2013 are analysed by means of airborne observations and global and mesoscale numerical simulations with horizontal mesh sizes of 16 km, 7.2 km, 2.4 km and 0.8 km. During both events westerly cross-mountain flow induced upward propagating waves in the troposphere and stratosphere and trapped waves in the lee of the mountains. Despite similar forcing conditions gravity wave breaking occured during the first event at altitudes between 25 km to 30 km due to weak stratospheric background winds, while waves propagated to altitudes above 30 km during the second event. In the lower troposphere trapped lee waves …

Palaeoclimatic changes explain Anatolian mountain frog evolution: a test for alternating vicariance and dispersal events

2002

Holarctic biodiversity has been influenced by climatic fluctuations since the Pliocene. Asia Minor was one of the major corridors for postglacial invasions in the Palearctic. Today this area is characterized by an extraordinarily rich fauna with close affiliation to European, Asian and Indo-African biota. However, exact scenarios of range expansion and contraction are lacking. Using a phylogeographical approach we (i) identify monophyletic lineages among Anatolian mountain frogs and (ii) derive a spatio-temporal hypothesis for the invasion process in Anatolia. We sequenced 540 bp of the mitochondrial 16S rRNA gene from 40 populations of mountain frogs from Anatolia, the Elburz Mountains and…

La questione del confine italo-francese sul Monte Bianco

2020

Even though the common interest of France and Italy in relation to their Alpine border should be enhancing co-operation on cross-border issues (such as improving climate change adaptation as well as preventing and managing risks) a dispute on the delimitation of the border in the area around Monte Bianco has arisen in last years. As any other international dispute on territorial borders, it presents three different plans of analysis: the interpretation of boundary treaties and their official maps; the legal weight of “other” maps; the relationship between the boundary treaty and subsequent practice of the Parties (above all the relevance of effectivités). This article shortly discusses thes…
