“…The Ganges-Brahmaputra drainage basin is primarily made up of igneous and metamorphic rocks, including granites and gneiss, although some sandstones, carbonates, shales, and conglomerates are present (Alam et al, 2003 Krishnaswami et al, 1992;Blum et al, 1998;Galy et al, 1999). The floodplain alluvial soils in the delta comprise a mixture of silts, clays, quartz, and carbonates (Coleman, 1969;Brammer et al, 1988;Uddin and Lundberg, 1998 (Xin, 1993;Bau et al, 2004). The complex geology of western Panama is poorly studied.…”

15Submarine groundwater discharge (SGD) to the ocean supplies Sr with less radiogenic 87 Sr/ 86 Sr than seawater, and thus constitutes an important term in the Sr isotope budget in the modern ocean. However, few data exist for Sr in coastal groundwater or in the geochemically dynamic subterranean estuary (STE). We examined Sr concentrations and isotope ratios from nine globally-distributed coastal sites and characterized the behavior of Sr in the STE. Dissolved Sr 20 generally mixed conservatively in the STE, although large differences were observed in the meteoric groundwater end-member Sr concentrations among sites (0.1 -24 µM Sr). Strontium isotope exchange was observed in the STE at five of the sites studied, and invariably favored the meteoric groundwater end-member signature. Most of the observed isotope exchange occurred in the salinity range 5-15, and reached up to 40% exchange at salinity 10.

“…[18][19][20][21][22][23][24] In addition, the 87 Sr/ 86 Sr composition of animals from a specific locality is influenced by non-geological sources, such as rainwater. [25][26][27] There is, however, limited 87 Sr/ 86 Sr biosphere data currently available for the study region, and we have, therefore, largely relied on predictions based on the geological literature and studies from comparable geological formations.…”

The hunter-gatherer transhumance model presents foragers as specialised hunters of migratory ungulates, which moved seasonally between coastal lowlands and interior uplands. We studied six animal teeth of horse (Equus hydruntinus) and red deer (Cervus elaphus) from four different archaeological sites: the Grotta di Vado all'Arancio, Grotta di Settecannelle, Grotta Polesini and Grotta di Pozzo, in central Italy to test whether the migratory patterns and seasonal variations recorded in their teeth were consistent with expectations of the transhumance model for this region during the late Upper Palaeolithic. Sequential sub-samples of enamel were analysed from each tooth for oxygen, carbon and strontium isotope ratios to reconstruct mobility and yearly seasonal variations. The results show little evidence that these animals were moving over different geological terrains throughout the year, although small variations in Sr isotope ratios and concentrations were detected that corresponded to probable seasonal variations as shown by variability in oxygen isotope sequences. The results do, however, demonstrate that Cervus elaphus and Equus hydruntinus had different ranging behaviours, with the former moving over wider areas than the latter. This methodology produces results appropriate to assess animal migratory behaviour and, in turn, to test the consistency of proposed models of hunter-gatherer subsistence and mobility strategies. Copyright # 2008 John Wiley & Sons, Ltd.Eurasian hunter-gatherer populations experienced rapid and extreme environmental changes from the Last Glacial Maximum to the early Holocene (ca. 18 000 to 8000 BP). e.g. 1,2 During this period profound socio-economic changes and technological developments took place that culminated with the transition to agriculture. Various models have been applied to explore the relationship between the environment and hunter-gatherer behaviour during the late-glacial in Mediterranean Europe. The hunter-gatherer transhumance model, a variation of the seasonal mobility model originally developed by Higgs, 3,4 presents foragers as specialised hunters of migratory ungulates that moved seasonally between coastal lowlands and interior uplands. In Italy, Barker hypothesised that hunter-gatherers of the late Pleistocene followed seasonally migratory herd species including Cervus elaphus and Equus hydruntinus between the Apennine uplands and the coastal plains. 5,6 These two locations offer seasonally distinct opportunities for grazing species: in winter the mountains are inhospitable and cold while the coastal plains remain grass-covered. In summer, instead, the lowlands are dry with little vegetation and the mountains remain vegetated. These distinctions would have been intensified in the late Pleistocene, and Barker argued that the seasonal climatic variations of this Mediterranean landscape would have suited wild species of grazing herbivores that could migrate between these two regions. 6 Although the hunter-gatherer transhumance model is attractive for various reasons...
