Vegetation dynamics of Kisima Ngeda freshwater spring reflect hydrological changes in northern Tanzania over the past 1200 years: implications for pa…
2021
13 pages; International audience; Kisima Ngeda (KN), a spring on the northern margin of saline Lake Eyasi, Tanzania, sustains an Acacia-Hyphaene palm woodland and Typha swamps, while the surrounding vegetation is semi-desert. To study the vegetation changes associated with this spring, which represents a plausible modern analog for the fossil springs documented in the nearby paleoanthropological and archaeological sites of Olduvai Gorge, we analyzed the pollen content of a 43 cm-long sediment core that documents vegetation changes since the last ~1200 years (from cal yrs. C.E. 841 to 2011). Our results show that (1) Hyphaene palms, which require meso-halophytic soil conditions were most abu…
The contribution of archaeological plant remains in tracing the cultural history of Mediterranean trees: The example of the Roman harbour ofNeapolis
2015
In this paper, we present a detailed record of the plant remains recovered on the palaeo-seafloors of Neapolis harbour, spanning ≈700 years, between the 2nd century BC and the 5th century AD, thus intersecting the entire Roman Imperial Age. The site preserved many cultivated or cultivable plant remains, especially from food related trees. This particular feature provided the opportunity to reconstruct the puzzling history of planting them and the Roman economy, especially with respect to food production, the market and to dietary habits. The evidence suggests that Prunus persica, Castanea sativa, Juglans regia and Pinus pinea were locally grown all along the investigated period, testifying …
