Implication of the biofilm ageing for the settlement of the vermetid gastropod Dendropoma cristatum (Biondi 1857)
2016
Dendropoma cristatumreefs are key-intertidal habitats of the central Mediterranean. Knowledge onD. cristatumbiology is presently scant, particularly on its early life stage. The development of embryos occurs inside the maternal shell, and the crawling larvae settle on hard substrates shortly after hatching. Epilithic biofilm is known to have implications in the settlement of many marine invertebrates; however whether biofilm plays a role in driving the vermetid settlement is unknown. In this study the microbial assemblage ageing is tested as apotentialtriggerforD. cristatumsettlement. A field experiment was set-up to compare the larval settlement rate on removable limestone cubes (5x5x2 cm)…
Settlement performance of the Mediterranean reef-builders Dendropoma cristatum (Biondi 1859) in response to natural bacterial films
2018
The gastropod Dendropoma cristatum is a biogenic engineer of the central Mediterranean, forming reefs along the lower rocky intertidal fringe with a remarkable ecological role. To understand whether reef-associated biofilm cultivable bacterial and biofilm ageing may trigger the settlement of the juvenile snails, a combination of laboratory techniques and field experiments was used. Reef-associated biofilm cultivable bacteria were isolated, and a settlement-choice experiment was performed in situ on artificial biofilms composed of i) a mixture of six biofilm-forming selected isolates, ii) all the cultivable bacteria, and iii) 13-, 23-, 32-day old biofilms formed under naturalconditions. Overall,sett…
Chronologie et périodisation des campaniformes en France méditerranéenne
2012
What is the current state of research, twenty years after the Ambérieu-en-Bugey colloquium, regarding the chronological setitng of the Bell Beaker horizon, the periodisation of pottery styles and the relationships between Bell Beakers and local groups in the late Neolithic in Mediterranean France ? A brief inventory of knowledge from 1992 together with research from the last two decades will allow us to re-evaluate stratigraphic evidence and radiocarbon dates and to examine the evolution of sttlement distribution and the artefact contexts and associations
Les modes d'habitat à l'âge du Bronze en France
2018
The many discoveries made in preventive archaeology have drawn the picture of a highly anthropogenic landscape in Bronze Age France. Timber post buildings are the most common type of dwellings however other types of construction (sills, mudbrick, …) that have lighter foundations and are more susceptible to erosion are considered less common due to the inherent problems of identification. Small dwellings from 25 to 40 m2 with a quadrangular 1 to 3 aisled plan and built to house a nuclear family are the most common,. Other types of buildings differ from this standardised plan such as the long rectangular dwellings in Alsace dating to the Early Bronze Age (type Eching) or the Early Bronze Age …
The Bronze Age in Lorraine: a proposed model of the settlement
2022
Thirty years of assiduous preventive archaeology practice in Lorraine have built up a stock of data that can be used for numerous archaeological problems with a spatial focus.For the Bronze Age, as for the other chronological periods, the archaeological occupations discovered during diagnostics and excavations are strongly correlated with current developments (motorways, TGV, housing estates, quarries, etc.). These occupations must be discussed in order to estimate their spatial representativeness. Similarly, the landscape characterisation, in which the occupations highlighted are situated, is an important step in defining the types of settlement.As most of the data comes from the national …

Rural settlement in the territorium of Ilici: the Roman farm of The Cabezo-Clot de Galvany (Elx, Alicante)
2015
Situado en el territorium de Ilici, en el paraje de El Clot de Galvany (Elx), junto a un humedal de tierras pobres, presentamos una granja romana (ss. I-III d.C.). Su posición periférica respecto al área centuriada ilicitana, los restos materiales aparecidos (molinos, ausencia de estructuras de transformación, aislamiento relativo) y la gran simplicidad estructural y funcional del conjunto remarcan el carácter autosuficiente de este núcleo. El área arqueológica tras la época romana queda deshabitada y sólo volvió a frecuentarse a partir del s. XVII, coincidiendo con el crecimiento demográfico de época moderna, como muestra la construcción de una ermita. Todo ello nos lleva a plantear cuesti…
Relative sea-level rise and potential submersion risk for 2100 on 16 coastal plains of the mediterranean sea
2020
The coasts of the Mediterranean Sea are dynamic habitats in which human activities have been conducted for centuries and which feature micro-tidal environments with about 0.40 m of range. For this reason, human settlements are still concentrated along a narrow coastline strip, where any change in the sea level and coastal dynamics may impact anthropic activities. In the frame of the RITMARE and the Copernicus Projects, we analyzed light detection and ranging (LiDAR) and Copernicus Earth Observation data to provide estimates of potential marine submersion for 2100 for 16 small-sized coastal plains located in the Italian peninsula and four Mediterranean countries (France, Spain, Tunisia, Cypr…
The Spread of English
2013
English descends from a set of Germanic dialects spoken 4,000 years or so ago in a small area of the far south of Scandinavia. The arrival of Germanic speakers on the island of Britain a millennium and a half ago led to the growth of the language we now call English. This language remained confined to this island for most of its history and, indeed, was not spoken in all parts of the island until extremely recently. During the last five centuries native-speaker English also spread to the Western Hemisphere and then to the Southern Hemisphere, leading to the development of new varieties of the language in the colonised areas, but also to the massive loss of indigenous languages in the Americ…
