The end of the Upper Palaeolithic in the Mediterranean Basin of the Iberian Peninsula

2012

This paper presents a synthesis of the Magdalenian in the Mediterranean Basin of the Iberian Peninsula, with special attention to the lithic and bone/antler assemblages, rock art, economy and radiocarbon dates. The data obtained in Cendres cave, situated in the middle of the Mediterranean Iberian Peninsula, permit articulation of the discussion about the Lower, Middle and Upper Magdalenian in this region. Furthermore, the paper discusses the end of the Magdalenian sequence with the Epimagdalenian industries.

Surviving the Holocene: Human Ecological Responses to the Current Interglacial in Southern Valencia, Spain

2009

For hunter-gatherer groups, the dramatic changes in climate at the end of the last glacial cycle necessitated rearrangement of land use, including shifts in mobility strategies, settlement location, and resource use. We examine these behavioral changes using lithic attribute data as well as spatial distributions of artifacts and features. Using data from intensive survey and excavation, we trace human ecological response through the onset of the current interglacial in central Mediterranean Spain, comparatively far from the margins of the north-temperate ice sheets.

Bioclimatology and Vegetation Series in Sicily: A Geostatistical Approach

2015

Tackling the Sicilian woody vegetation as a case-study, this work aims to verify the correspondence between Rivas-Martínez's bioclimatic units and the main vegetation series in the Mediterranean region. Following this approach, one macrobioclimate and 25 bioclimatic type belts can be recognized in Sicily. By means of a geostatistical analysis based on WorldClim data sets, cartographic models of the distribution range of each single bioclimatic unit were obtained and combined with vegetation data, in order to develop a new regional spatial framework, integrating climatic and vegetation data. Fidelity of each vegetation unit to a given climatic range was then evaluated as percent distribution…

New data for the characterization of Mediterranean Upper Magdalenian: the Cendres Cave (Teulada-Moraira, Valencian Country)

Monitoring temporal changes in the spatial patterns of a Mediterranean shrubland using Landsat TM images

2001

Summary The overall goal of this study is to understand the structure and function of a Mediterranean shrubland at landscape scale by means of satellite images and GIS. Specifically, to assess the sensitivity of several spatial statistics to characterise landscape pattern, measure fragmentation and quantify the change through time. We study the landscape structure of a Mediterranean shrubland located in the east part of Spain (Valencia) and the change in spatial patterns of different shrubs types from 1984 to 1994. To accomplish these objectives, we used 10 Landsat™ images from 1984 to 1994 (except 1988) to which a geometric correction and an atmospheric normalization was applied. In additi…

Macrofungi in Mediterranean maquis along seashore and altitudinal transects

2014

In semi-arid Mediterranean environments, fungal activity is fundamental for buffering biotic and abiotic stress to the plant and for sustaining a vegetation cover. Despite the important role that fungi play in habitats stability, mycological data from Mediterranean ecosystems are scarce and fragmentary. We investigated fungal diversity in several areas characterized by Mediterranean maquis, from continental Italy, Sicily, and Greece in order to contribute to the analysis of distribution, ecology, and diversity of macrofungi in evergreen sclerophyllous shrublands at different elevation and distance from the seashore across the Mediterranean Basin. Several fungal taxa that are remarkable due …

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.

Assessing disproportionate costs to achieve good ecological status of water bodies in a Mediterranean river basin.

2011

Water management is becoming increasingly important as the demand for water grows, diversifies, and includes more complex environmental concerns. The Water Framework Directive (WFD) seeks to achieve a good ecological status for all European Community water bodies by 2015. To achieve this objective, economic consideration of water management must be given to all decision-making processes. Exemption (time or level of stringency) from the objectives of the EU Directive can be justified by proving that the cost of implementing measures is disproportionate to the benefits. This paper addresses the issue of disproportionate costs through a cost-benefit analysis (CBA). To predict the costs, the fu…

Late Messinian to Early Pliocene paleoenvironmental changes in the Melilla Basin (NE Morocco) and their relation to Mediterranean evolution

2003

Abstract Three major paleoenvironmental changes have been recognized during the late Miocene to Early Pliocene in the Melilla Basin (Northeastern Morocco) and compared with the regional events that affected the Mediterranean hydrology during this crucial period. The first change was the definitive conversion of the restricted marine conditions that prevailed since the end of the reef carbonate complex into lacustrine environments; this occurred around 5.8 Ma which is earlier than in the rest of the Mediterranean where the Lower Evaporites were still forming. These lacustrine settings display great similarities with the Lago-Mare environments that started in the Mediterranean during the depo…

Western Mediterranean Climate Response to Dansgaard/Oeschger Events: New Insights From Speleothem Records

2019

The climate of the western Mediterranean was characterized by a strong precipitation gradient during the Holocene driven by atmospheric circulation patterns. The scarcity of terrestrial paleoclimate archives has precluded exploring this hydroclimate pattern during Marine Isotope Stages 5 to 3. Here we present stable carbon and oxygen isotope records from three flowstones from southeast Iberia, which show that Dansgaard/Oeschger events were associated with more humid conditions. This is in agreement with other records from the Iberian Peninsula, the Mediterranean, and western Europe, which all responded in a similar way to millennial‐scale climate variability in Greenland. This general incre…
