 Well, let's change a bit the topic of the session, as Laura said, I'm going to talk about new data palombramente para mi Córsica that enable the reconstruction of the environmental framework of my organization in the island. Well, just to present the study area, it's located in the western Mediterranean in the island of Córsica, and we studied in two sites, San Flogán, it's located in the north of Córsica, and the Antarela, it's located in the opposite extreme of the island in the southern area. In San Flogán we studied one core, and in the Antarela we studied three cores, and in this presentation room we only present two of these three cores. Well, the objective of this work is the reconstruction of vegetation history, and climate change in Córsica, and also in order to evaluate the differences between the north and the south of the island, and one important objective is to assess human impact, and we are mainly focused on theolithic times, and in order to find the earliest evidence of human impact in the island. One important objective is also to take first multi-proxy sequences in these areas of the island, and in the past there were a lot of studies carried out mainly by Moe's Bay, but there were all the studies without a good geological control, and one objective was to have a lot of C14 dates in order to have a geological control of environmental changes. There are some evidences of the alinearithic in Córsica, and well, the alinearithic in Córsica is making more tests in 8000 to 7000 before present, and it consists of the cardiovascular culture, and we have in both areas, in the central and in the north, we have to the alinearithic sites to spread in the other skin types, and in the southern area we have also two alinearithic sites, alineasenola and the unifacil. Well, the materials in the study, we studied three cores, the first ones in Flamán, in North Córsica, and we studied, we obtained data of the needle to the alinearithic, and also in Roman and Middle Ages, and we studied Xerrer, Rosoninbíxian, Laceoinsides, and also Polenic and Polynomodal analysis. In Pianzadella 1, we obtained the data for the alinearithic, and we conducted analysis of Polen and Rosoninbíxian in Ustracoda and Phamilifera, and finally in Piantarella 3, we obtained data for the needle to alinearithic, and we developed Rosoninbíxian, we studied size, Polen analysis, and metaphosive analysis. For Piantarella, the core one in Piantarella in Córsica, and we applied the study of Ostracoda and Phamilifera in order to reconstruct the evolution of the environment, and in this diagram we can see that in the alinearithic, there was a Black-Asian-Marine environment, so in the lagoon there was an input of marine water, and then in the transition to the late Oroxin, there's a change, it's still a Black-Asian-Marine environment, but with the present diversity of Ostracoda, that means that the input of marine water was decreasing. Then in Roman and Middle Ages times, the environment changed to a freshwater lagoon, so the connection with the sea was closed. For the Polen analysis, we can see open vegetation, since the alinearithic, mainly composed by Mediterranean scrublands, composed mainly by Erika and Xistacea, and we can see also from the alinearithic evidences of Ostracoda, evidences of agriculture, a permanente signal of cerealia during the sequence. We can see also in that blue, high bar values of Kenakodiaceae, that suggest the existence of a saline environment, consisting of marxion. So during the alinearithic, we can say that open vegetation existed in Soudalcorsica, with the doubt, with the question, if among Erika species we can have shrubs or Erika arboria that can compose forests, and if there is a doubt, if it consists of shrublands, or it could be also an Erika arboria forest, the landscape, but the forests will have been dominated by Xistacea, showing the midolos in climate ultimum in this area, with the predominance of growth in the serious trees, like the serious Kirkus and Corillus, and we can see also the alinearithic evidences of Fariculcha and Ximanipa in the southern part of Corsica. The other core study de anáxis de Antaela III that provides data for the midolithic and the inelithic, and we can see also the same signal of the vegetation dominated by Erika and Xistacea, so the dominance of Mediterranean scrublands, and here we can see the reduction of saline indicators, the reduction of canopodiesa, and the increase of freshwater indicators. So we have the same question like in the area in the alinearithic, if there is an open vegetation or could be Erika arboria forest, but we found some macrophosius in this sequence in the Antaela III and here we have the Charcol of Erika, and a seed of Erika that could be identified as a species level. It's Erika ascoparia and it's a species of Erika that consists of shrubs, not trees. So the hypothesis of the existence of Erika arboria forest would be less probable than the dominance of Mediterranean shrublands. In this sequence we can see an important change in the Mediterranean, we have the predominance of mesophilus taxa, showing the Holocentlaman opthimum, and then in the Mediterranean we see a decrease of mesophilus and the increase of evering mesclerophilus, showing the changing climate, maybe showing the decrease in precipitation and the difference between seasons. In this sequence we also had regular occurrence of cereales showing permanent human impact during the Neolithic and the Neolithic, except in the face of 50000, and we can see an increase of fresh water indicators showing this brackish environment that is in transition to fresh water environment. Well, here in this sequence we can see the integration of both cores of Pianta de la I and III and we can see red human impact episodes and in dark blue, peaks of saline indicators and in black blue, the peaks of fresh water indicators. For sin flogán, located in the north of the island, we see a very different landscape, we obtain data for the middle and the Neolithic in the water part of the island and we can see the evering mesclerophilus III, that Kirkus elexcortifera predominating in the landscape and we see a forest environment, it's different compared with southern Corsica, where Mediterranean straplands dominated and we see here in northern Corsica first evidence of agriculture in Middle Neolithic. We have serious area problem in Middle Neolithic, not in Neolithic. Well, in this diagram we can see in red the human impact changes and in the environmental change, the most important environmental change is the transition from fresh water environments during Middle Neolithic and then Neolithic to the input of marine water and the composition of marshlands during Roman and Middle Aces. The integration of all these multiproxiedata allowed us to reconstruct the city of reconstruction. These are very new data, just yesterday and while in blue, in light blue, we can see the data for Neocorsica and the data for the southern Corsica. We can see the evolution of the increasing level of the sea and just to conclude, some differences are very clear between Northern Corsica and Southern Corsica that also show the different climate conditions. In Northern Corsica, there were dense forests in the scale of those trees and in the Southern Corsica area we find more open vegetation dominated by the Mediterranean straplands by the monkeys and these Mediterranean straplands would have consisted of the natural vegetation of the southern part of the island since the Middle Aces and what we want to highlight with this study is the first evidence of the Neolithic human impact based on the environmental proxies and while the differences between southern Corsica and Northern Corsica is that here the evidence of human impact is documented in the southern area and finally the multiproxies analysis provide new data for the construction of sea level evolution and that's what's aligned and will develop in the future. Well, thanks for your attention.
