Weblong-term development of a forest ecosystem [18–21]. In recent studies, Ca isotope fractionation has been used in marine carbonate stud-ies [22–26] and stable Ca … WebSr isotope ratios provide a valuable tracer for provenance studies of alkaline earth elements in forested ecosystems, but its usefulness is limited when deciphering biogeochemical processes involved in the terrestrial Ca cycle. Ca isotopes in combination with Sr/ Ca ratios reveal more complex processes involved in the biogeochemistry of Ca and ...
WebIn favourable conditions, the 87Sr/86Sr isotope ratios of the Sr delivered by rain and soil mineral weathering differ. Assuming that Ca and Sr behave similarly in forest ecosystems, several authors have used the 87Sr/86Sr variation in forest compartments to calculate the contribution of rain and mineral weathering to Ca fluxes and pools. However, there are a … Webto understand Ca cycling pathways in order to identify sensitive ecosystems, minimize further losses of Ca, and evaluate potential mitigation strategies.
