2500 Years of European Climate Variability and Human Susceptibility

2011

Climate variations influenced the agricultural productivity, health risk, and conflict level of preindustrial societies. Discrimination between environmental and anthropogenic impacts on past civilizations, however, remains difficult because of the paucity of high-resolution paleoclimatic evidence. We present tree ring-based reconstructions of central European summer precipitation and temperature variability over the past 2500 years. Recent warming is unprecedented, but modern hydroclimatic variations may have at times been exceeded in magnitude and duration. Wet and warm summers occurred during periods of Roman and medieval prosperity. Increased climate variability from similar to 250 to 6…

Du Néolithique récent à l’âge du Bronze dans le Centre Nord de la France : les étapes de l’évolution chrono-culturelle

2011

Die seit 2001 im Rahmen eines PCR (Programme Collectif Régional) durchgeführte Gemeinschaftsarbeit über das Ende des Neolithikums und den Beginns der Bronzezeit im Zentrum Nordfrankreichs führt heute zu einer neuen Periodisierung der Zeit zwischen 3600 und 1800 v. Chr. in acht Etappen. Obwohl, insbesondere bezüglich der Transition zwischen dem Mittel-und dem Jungneolithikum einerseits und dem Jung-und dem Endneolithikum andererseits, auch weiterhin einige Lücken bestehen, erlaubt dieser präzisere Rahmen die Hauptetappen im Zentrum Nordfrankreichs mit denen der benachbarten Regionen zu synchronisieren, um eine dynamischere Vision der kulturellen Phänomene vorzuschlagen.

Typification of the name Abies nebrodensis (Pinaceae)

2017

Abies nebrodensis, endemic to the Madonie mountains (central-north Sicily), was originally described by Lojacono Pojero as A. pectinata var. nebrodensis and later raised to the rank of species. The species is considered to be critically endangered and was thought to be extinct until an extant population was rediscovered in 1957. The name is here lectotypified on a specimen preserved at NAP.

The Forcart Collection of lamps from Fayum

2019

The Forcart collection of Ptolemaic, Roman and Late Roman lamps from Fayum is today the largest single-collector Egyptian lychnological corpus owned by a Swiss public institution, the Geneva Museum of Art and History, which acquired it in 1923. The importance of the 145 lamps in this collection is twofold. Firstly, all the artifacts were offered to Max Kurt Forcart by the different directors of excavations operating legally in the Fayum area during the first two decades of the 20th century, giving us a clear—even if generic—finding area, contrary to collections purchased from the various antiquaries. And secondly, even if incomplete compared to the richness and diversity of the Fayum worksh…

Consigner ou fabriquer la légende d’Alexandre le Grand ? Arrien face à la tradition dans l’Anabase

2021

Dans l’Anabase, Arrien convoque des sources nombreuses et s’y refere souvent explicitement par une large gamme de mentions, allant du nom des auteurs aux expressions « ce qui est dit » ou « le bruit qui court ». Dans un contexte ou, habituellement, « un historien antique ne cite pas ses sources », selon une formule de Paul Veyne, ce choix est surprenant. Arrien est-il condamne a n’etre que le passeur d’une tradition deja toute constituee sur le conquerant, incapable de prendre lui-meme en charge le recit ? C’est precisement sur la nature exacte de la transmission du materiau historique dont il herite, sur ses criteres et sa finalite que porte cette etude. En realite, non content d’enregistr…

Reappraisal of some species of the giant galericine Deinogalerix (Mammalia, Eulipotyphla, Erinaceomorpha, Erinaceidae) from the Miocene of south-east…

2019

A revision of the remains of Deinogalerix from the Terre Rosse of Gargano, stored at the Department of Earth Sciences of Florence, improved our knowledge of the genus. The goals of this study are to clear the taxonomic status of the specimens and to tackle several issues connected with the evolutionary relationships of the different species. The sample of dental remains of Deinogalerix freudenthali provides new information, which confirms that this species belongs to the most primitive members of the genus, alongside D. masinii. It is now clear that D. freudenthali is very close to the hypothetical ancestor of all other Gargano species, except D. masinii. Nonetheless, the oldest fissures of…

Holocene vegetation and fire history of the mountains of Northern Sicily (Italy)

2016

Knowledge about vegetation and fire history of the mountains of Northern Sicily is scanty. We analysed five sites to fill this gap and used terrestrial plant macrofossils to establish robust radiocarbon chronologies. Palynological records from Gorgo Tondo, Gorgo Lungo, Marcato Cixé, Urgo Pietra Giordano and Gorgo Pollicino show that under natural or near natural conditions, deciduous forests (Quercus pubescens, Q. cerris, Fraxinus ornus, Ulmus), that included a substantial portion of evergreen broadleaved species (Q. suber, Q. ilex, Hedera helix), prevailed in the upper meso- mediterranean belt. Mesophilous deciduous and evergreen broadleaved trees (Fagus sylvatica, Ilex aquifolium) dominat…
