Horse exploitation at the Late Upper Palaeolithic site of Oelknitz (Thuringia, Germany) with special reference to canine modifications

2012

Abstract The faunal assemblage from Structure 5 of the Magdalenian settlement Oelknitz (Thuringia, Germany) was analyzed. The fauna is dominated by horse. All stages of butchery from skinning to marrow extraction were performed within the horse assemblage. In addition to this, various stages of organic artifact production could be documented. Two fragmentary equid canine teeth were of particular interest. They are the only documented canines from Structure 5, which otherwise contained a large amount of teeth. Both canines show traces of human modification. They were cut out of the jaw while still in the alveole. On both canines, lateral incisions were performed at the cervix dentis and the …

The Geochemistry of Basalt Handaxes from the Lower Palaeolithic Site of Ma‛ayan Baruch, Israel-A Perspective on Raw Material Selection

2014

The Upper Acheulian site of Ma‛ayan Baruch, northern Israel, is primarily known for its exceptionally large assemblage of thousands of flint handaxes. Within this assemblage, a minute collection of basalt handaxes was retrieved as well, representing particular technological choice within the Upper Acheulian. Using geochemistry, we were able to determine that these basalt handaxes were not made from local basalt, but from different sources. Thus, the use of basalt at the site does not represent an ad hoc choice of using local raw material but, rather, a more complex technological choice pertaining to variability in raw material selection in the Lower Palaeolithic Levant.

Do small marinas drive habitat specific impacts? A case study from Mediterranean Sea

2011

Many human activities add new structures to the marine landscape. Despite the fact that human structures cause some inevitable impacts, surprisingly little information exists on the effects of marina on natural marine assemblages. The aim of this paper is to assess habitat-specific response of benthic sessile organisms of rocky shores in relation to the presence of a small marina. Sampling was carried out at three coastal habitats (midshore, lowshore and subtidal) by means of visual censuses adopting an after-control-impact (ACI) experimental design. It appears that the marina affects the structure and composition of benthic communities of both the midshore and the lowshore. Little effect w…

Mammal assemblage composition predicts global patterns in emerging infectious disease risk

2021

Abstract As a source of emerging infectious diseases, wildlife assemblages (and related spatial patterns) must be quantitatively assessed to help identify high‐risk locations. Previous assessments have largely focussed on the distributions of individual species; however, transmission dynamics are expected to depend on assemblage composition. Moreover, disease–diversity relationships have mainly been studied in the context of species loss, but assemblage composition and disease risk (e.g. infection prevalence in wildlife assemblages) can change without extinction. Based on the predicted distributions and abundances of 4466 mammal species, we estimated global patterns of disease risk through …

The fossil rodent faunas of the localities Alcoy 2C and 2D (Alcoy Basin, Spain). Implications for dating the classical locality of Alcoy-Mina

2014

In the Gormaig area (Alcoy basin, SE Spain) a number of fossil mammal localities are known, of which only the classic site of Alcoy-Mina, known since the mid-19th century, has yielded remains of macrofauna. In the vicinity of this site are the localities of Alcoy-2C (AL2C) and Alcoy-2D (AL2D), probably representing the levels of Alcoy-Mina. The faunal assemblage allows dating the AL2C and AL2D localities as Early Pliocene (end of the Early Ruscinian or early-late Ruscinian boundary, MN14-MN15). Several taxa (Pliopetaurista and Glis) are thought to have affinities for humid and close biotopes. En el área del Gormaig (cuenca de Alcoy, SE España), se conocen toda una serie de yacimientos de ma…

Microremains from El Mirón Cave human dental calculus suggest a mixed plant/animal subsistence economy during the Magdalenian in Northern Iberia

2015

Abstract Despite more than a century of detailed investigation of the Magdalenian period in Northern Iberia, our understanding of the diets during this period is limited. Methodologies for the reconstruction of Late Glacial subsistence strategies have overwhelmingly targeted animal exploitation, thus revealing only a portion of the dietary spectrum. Retrieving food debris from calculus offers a means to provide missing information on other components of diet. We undertook analysis of human dental calculus samples from Magdalenian individuals (including the “Red Lady”) at El Miron Cave (Cantabria, Spain), as well as several control samples, to better understand the less visible dietary compo…

Structural and functional organization of fish assemblages in a Mediterranean shallow CO2 vent.

2017

Gli effetti dell’acidificazione degli oceani a livello globale hanno richiamato l’attenzione degli scienziati su dei sistemi marini naturali quali i vent superficiali di CO₂. Si tratta di mesocosmi naturali, in quanto su piccole scale spaziali (anche di pochi metri) si osservano marcati gradienti di pH, dove poter testare ipotesi ecologiche dell’acidificazione delle acque marine. Obiettivo della tesi è studiare le risposte della popolazione ittica alla riduzione del pH in vent superficiali mediterranei utilizzando numerosi descrittori, quali la struttura di comunità, l’organizzazione trofica, le caratteristiche e la composizione chimica delle strutture carbonatiche. Inoltre poiché i vent so…

Submersed in the water, buried in the ground: comparative studies on metal assemblages and single finds from french Iron Age non-funerary contexts (V…

2020

Metal hoards are emblematic discoveries of European protohistoric societies and therefore an extremely dynamic research theme. However, even though there are many synthetic studies concerning Bronze Age practices, they are much less frequent concerning Iron Age deposits. In fact, since 1995 (Kurz 1995), no synthetic inventory on this subject had been carried out despite the regular increase in the number of discoveries since the development and multiplication of preventive archaeological excavations. Under these conditions, it seemed important to update the data and this led to the completion of a master's degree on this subject in 2011 (Le Cozanet 2011). Since then, our research hasn‘t cea…
