Late glacial-postglacial North African landscape and forestmanagement : Palynological and anthracological studies in the caves of Kaf Taht el-Ghar an…
2021
This work presents the anthracological and archeopalynological results obtained within the project AGRIWESTMED (ERC AdG 230561), which has involved a comprehensive retrieval of archeobiological remains based on a systematic sampling strategy, beyond the recovery of the usual archeological materials. These surveys were conducted on three sites located in the North of Morocco: the cave of Kaf Taht-el-Ghar, 8 km southeast from Tetuan, and two caves within the El Khil complex, close to Tanger. Both plant micro- and macro-remains (charred wood) were studied through palynological and anthracological analyses, respectively.
Changing patterns of eastern Mediterranean shellfish exploitation in the Late Glacial and Early Holocene: Oxygen isotope evidence from gastropod in E…
2016
Abstract The seasonal pattern of shellfish foraging at the archaeological site of Haua Fteah in the Gebel Akhdar, Libya was investigated from the Epipaleolithic to the Neolithic via oxygen isotope (δ 18 O) analyses of the topshell Phorcus (Osilinus) turbinatus . To validate this species as faithful year-round palaeoenvironmental recorder, the intra-annual variability of δ 18 O in modern shells and sea water was analysed and compared with measured sea surface temperature (SST). The shells were found to be good candidates for seasonal shellfish forging studies as they preserve nearly the complete annual SST cycle in their shell δ 18 O with minimal slowing or stoppage of growth. During the ter…
Systemic chemotherapy and pressurized intraperitoneal aerosol chemotherapy (PIPAC): A bidirectional approach for gastric cancer peritoneal metastasis
2019
Abstract Background Few patients affected by gastric cancer peritoneal metastasis (GCPM) are offered locoregional treatment, despite several proof-of-efficacy trials. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has emerged in recent years as a promising tool to control peritoneal carcinomatosis. The combination of PIPAC with systemic chemotherapy may offer a greater clinical benefit than standard treatment alone. Methods A single-center cohort of 28 consecutive patients affected by GCPM was scheduled for bidirectional treatment, comprising PIPAC and systemic chemotherapy, from September 2017 to September 2019. Data recorded included safety, efficacy and survival outcomes. Ascit…

Antiguas excavaciones, nuevas respuestas. El yacimiento epimagdaleniense de la Cova del Clot de l'Hospital (Roquetes, Baix Ebre)
2015
El objetivo de este trabajo ha sido estudiar los materiales obtenidos con las excavaciones de Francesc Esteve Gálvez en la Cova del Clot de l’Hospital (Bajo Ebro), yacimiento de finales del Pleistoceno-inicios del Holoceno, descubierto por él mismo el año 1945. La representación de raspadores, truncaduras, buriles y laminitas de dorso, entre otros tipos, permite atribuirlo al Epimagdaleniense, atribución corroborada por dos fechas radiocarbónicas sobre huesos de fauna: 11.115 y 10.045 BP. De esta forma, este yacimiento se suma a un numeroso conjunto de yacimientos del período citado, conocidos en las provincias de Tarragona y de Castellón de la Plana. Así mismo, el estudio de los restos fau…
Kaļķaino zāļu purvu veģetācijas sukcesija Engures ezera dabas parkā
2015
Eiropā kaļķainu zāļu purvu platības pēdējā gadsimta laikā ir strauji sarukušas, jo tās netiek atbilstoši apsaimniekotas. Dabiskās sukcesijas gaitā šie biotopi aizaug ar kokiem, krūmiem un graudzālēm. Šī tendence vērojama arī Engures ezera dabas parka kaļķainos zāļu purvos. Viena no dabas parka zāļu purvu lielākajām vērtībām ir augstā orhideju sastopamība. Darba mērķis ir noskaidrot sukcesijas ietekmi uz augu sabiedrībām un orhideju cenopopulācijām. Pētījuma ietvaros aprakstīti 787 veģetācijas parauglaukumi. Biežāk sastopamajām orhideju sugām novērtēta vitalitāte un sastopamība. Dabas parka zāļu purva kvalitāte vērtējama kā vidēja, savukārt orhideju vitalitāte kā zema līdz vidēja, bet sastop…
Explotació dels mamífers i economia de les darreres comunitats caçadores-recol·lectores del vessant mediterrani ibèric durant la transició Tardiglaci…
2015
En el presente trabajo se realiza el estudio zooarqueológico de los vertebrados terrestres explotados por los grupos humanos de los niveles tardiglaciares de los yacimientos de Santa Maira (boca Oeste) y Nerja (sala del Vestíbulo). A partir de los datos obtenidos para las facies culturales Magdaleniense / Epipaleolítico / Mesolítico se caracterizan las tendencias de cambio en los modelos económicos de las últimas comunidades cazadoras-recolectoras de la península ibérica. Estas secuencias se contextualizan así mismo en la zona biogeográfica mediterránea peninsular. Entre los resultados obtenidos cabe destacar la definición y caracterización de un modelo económico "tardiglaciar", donde el mo…
Pots, plants and animals: Broad-spectrum subsistence strategies in the Early Neolithic of the Moroccan Rif region
2019
Abstract The transition from hunter-gathering to food-producing societies in the Mediterranean zone of north Africa was complex and variable, likely influenced by local ecological conditions as well as the socio-economic origins of the population. The adoption of domestic plants and animals was piecemeal, with hunting and gathering continuing as an important part of local subsistence strategies. Here, we investigate the timing and extent of the adoption of agricultural practices, namely herding and cultivation, in three diverse coastal and inland Early Neolithic sites in the Mediterranean Maghreb region, namely Ifri Oudadane, Ifri n’Etsedda and Hassi Ouenzga. Results from absorbed lipid res…
Late Mesolithic burials at Casa Corona (Villena, Spain): direct radiocarbon and palaeodietary evidence of the last forager populations in Eastern Ibe…
2013
Abstract Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the…
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.
