From the Mesolithic to the Neolithic on the Mediterranean Coast of the Iberian Peninsula
2009
This paper summarizes early Holocene cultural sequences, economic strategies, and social dynamics on the Mediterranean coast of the Iberian Peninsula. Recent research in the central-southern regions of Valencia provides important diachronic information, particularly for discerning the nature of the shift from a hunter-gatherer lisfestyle to agricultura. If biogeographic conditions played a leading role in determining exploitation strategies, the recognizing distinctive social responses is crucial for understanding the impact of the changes that occurred.
A HYDRAULIC CONDUCTIVITY MODEL POINTS TO POST-NEOGENE SURVIVAL OF THE MEDITERRANEAN OLIVE
2004
Research on the subfossil record and paleoecology of Olea europaea suggests a new interpretation of its history and ecology with reference to the Mediterranean climate since the Neogene. New results are based on the wood anatomy of ancient and extant Olea and a model estimating hydraulic conductance established for wild forms belonging to Olea europaea subsp. europaea. These suggest that during glacial periods wild olive populations survived in protected microenvironments, particularly riparian habitats. Thereafter, the postglacial expansion of olive associated with climatic warming took place from these refuge areas. This new evidence suggests that the continued existence of Olea in Medite…
The barren Messinian Tripoli in Sicily and its palaeoenvironmental evolution: suggestions on the exploration potential
2016
New observations on the Sicily Messinian Tripoli have yielded a variably thick diatomitic, calcareous and shaly rock interval marked by an upwards disappearance of calcareous and siliceous plankton (barren lithosome), coexisting with a variability in vegetal remains and significant amounts of amorphous organic matter (AOM). Facies analysis associated with biostratigraphy and palaeoecology of the several field and borehole sections has been framed in a well-accepted chronological scheme that points to this barren interval coinciding with the stratigraphic upper and younger part of some Tripoli sections (bituminous Tripoli) located in the northern part of the study area. Biostratigraphically,…
L’audition chez les primates : entre forme, fonction, écologie et comportement
2019
The order Primates is composed of species whose morphologies, life history traits and behaviors are very diversified. The oldest representatives are dated about 65 million years. Because of this diversity, studies have focused on understanding the relationships between different parameters. Among the morphological structures studied, the basicranium, in particular the characters of the ear, have very often been considered in a phylogenetic perspective. Since the development of new acquisition techniques such as micro-tomography (μCT), new data are available. Thus, the interest for the morphology of the inner and middle ear, hitherto difficult to access, is growing. The structures of the ear…
