ABSTRACT: Cores from four coastal plains of the Mar Ligure Sea in N Tuscany and E Liguria (Italy) were investigated by means of pollen analysis to delineate the Holocene landscape history of the NW Italian coasts. In the first half of the Holocene (c. 9800–7000 cal. yr BP) all four sites show elevated percentages of Abies pollen which suggest the local presence of fir woods (with Ulmus, Tilia, etc.). In the second half of the Holocene (from 7000 cal. yr BP), Abies becomes locally extinct along the coasts leaving space for the development of mosaic landscapes formed by open meso-thermophilous woods (with deciduous Quercus, Alnus, Corylus) and Mediterranean maquis (with Erica cf. arborea). The new data represent a significant contribution to the reconstruction of the landscape history of the NW Italian coasts and of the history of fir in Italy. Along all examined
cores discontinuous pollen records show that initially the coastal areas were characterized by retrodunal wetlands; after c. 6000 cal. yr BP only the larger plains in N Tuscany remained extensively damp while the smaller plains in E Liguria were buried (and/or drained). Thus, these buried deposits of ‘fossil’ coastal wetlands proved to be only partially useful for high-resolution environmental archaeology and history studies. Nonetheless they are unique traces of ecosystems that provided important local economic resources for millennia and formed elements of the coastal cultural landscapes which have almost totally disappeared today

ABSTRACT: A 90 m deep core from the Massaciuccoli lake basin (Tuscany, Italy) offers new material for improving the knowledge of the Holocene vegetation history in the coastal plains in Tuscany and Liguria bordering the Mar Ligure (Ligurian sea). In this paper, an assessment of the upper part of the core is presented. During the Holocene, the area was covered by woodlands whose composition changed in time. Numerous oscillations of the tree taxa were recorded which can probably be connected to sea level variations that had a strong influence on the depth of the water table. Human impact is evident particularly at ca. 4200–2500 b.p. when traces of opening of the woodland accompanied by noticeable pollen percentages of Vitis could suggest an early agricultural practice favouring this native plant. The new data have been integrated with previous palaeobotanical and archaeobotanical research. The occurrence of coastal wetlands has been shown. Throughout the Holocene, Mediterranean evergreen vegetation is generally poorly represented; it becomes widespread only in the late Holocene, suggesting that its establishment was probably favoured by the management practices in the coastal plains, particularly land reclamations, starting from the Roman period

Palynological analyses applied to a case of kidnapping in Italy
No full textLa conoscenza degli ambienti che hanno fatto da sfondo ad atti criminosi può costituire una fonte di informazioni utili per le indagini sia in fase iniziale, per l'acquisizione di indizi, sia in fase finale, per la verifica delle ipotesi o conclusioni raggiunte. Nel caso qui presentato, sono state svolte indagini di botanica forense, su polline e su alcuni macroresti, in relazione a un sequestro di persona. Parallelamente è stata condotta un’analisi mineralogico petrografica dello stesso materiale. I campioni analizzati sono stati prelevati da materiale aderente al veicolo utilizzato per il sequestro (parafanghi e pedane dell'abitacolo) e dagli indumenti del sequestrato dopo la sua liberazione (vestiti e scarpe). Le informazioni ottenute sono riconducibili agli spostamenti e ai luoghi di permanenza del sequestrato e dei sequestratori
Palynology of a resin from an Egyptian coffin of the second century B.C.
No full textA palynological analysis was carried out on a small amount of resin from the inside of an anthropoid Egyptian stone coffin from the second century B.C. Pinus halepensis Miller is the best represented resiniferous plant (5.3%) in the pollen spectrum and the botanical origin of the resin can be ascribed to it. The only group of pollen which is relatively abundant in the spectrum is Poaceae (29.6%). This high percentage suggests that grasses were in bloom during the period the resin was collected (late spring or summer). Pollen of Quercus ilex. Olea europaea, Ostrya carpinifolia, Castanea sativa were also found. Pollen grains of Hordeum and Avena/Triticum types together with those of Plantago, Urtica, Chenopodiaceae, Rumex and Artemisia represent anthropogenic indicators. A phytogeographical interpretation of the found pollen assemblage suggests the eastern part of the Mediterranean as the most probable area where the resin was collected. The presence of Cedrus libani pollen suggests an origin from south-eastern Turkey, north-western Syria or northern Lebanon. The flora of this area is in accordance with the pollen assemblage found in the studied resin
