Isotopes of strontium (Sr) are a useful tracer for weathering, atmospheric fluxes, cation biocycling, and pedogenesis. We present basic models for application of strontium isotopes to the soil-vegetation-atmosphere system. The mathematical formulations fall into the general categories of: (1) steady-state models, in which isotopic ratios remain constant over the time scale of interest; and (2) time-dependent...
Through the cooperative efforts of the Scientific Committee on Antarctic Research (SCAR) Evolution and Biodiversity in Antarctica (EBA) Project and the Latitudinal Gradient Project (LGP), a monitoring network was established in Victoria Land in 2002 to assess the impacts of climate change on vegetation, soils, active-layer dynamics, and permafrost across a latitudinal gradient. In this study, we report...
The European Union Site of Community Importance Pineta San Vitale (Ravenna, Italy) is located in a complex lagoon system nearby the Adriatic Sea. This area is affected by relevant environmental pressures related to subsidence, groundwater salinization and industrial contamination. The occurrence of rare earth elements (REE), and the characterization of processes that control their migration in the...
