“…Broadley et al (2003) demonstrated the importance that phylogenetic effects in the variation of Ca concentration in angiosperms might have for predicting transfer coefficients and managing human dietary intakes of Ca. Given that Ca and Sr are known to behave similarly during soil-to-plant transfer (Andersen, 1967;Veresoglou et al, 1995Veresoglou et al, , 1996, we hypothesised that there is a phylogenetic effect on Sr concentrations in plants and that this might be useful for predicting transfer coefficients, managing dietary intakes and selecting plants for phytoextraction of 90 Sr. Here, using the same statistical methods as Broadley et al (2003), we report an analysis for 103 taxa we grew and 66 taxa from the literature, that quantifies a phylogenetic effect on Sr content of angiosperms and compares it to that of Ca.…”

“…It has also long been clear that increases of two-or three-fold in plant uptake of 90 Sr might make it possible to decontaminate soils of 90 Sr using plant uptake (Romney et al, 1957;Nishita et al, 1958;Fuhrmann et al, 2002). Soil properties clearly affect soil-to-plant transfer of 90 Sr (Abbazov et al, 1978;Roca et al, 1997;Askbrant and Sandalls, 1998) but differences between plant species in uptake from the same soil have also long been known to make a significant contribution to differences in soil-to-plant transfer (Andersen, 1967;Garret et al, 1971;Veresoglou et al, 1995). Here, we present a phylogenetic analysis of inter-species differences in Sr concentrations in plants.…”

A Residual Maximum Likelihood (REML) procedure was used to compile Sr concentrations in 103 plant species from experiments with Sr concentrations in 66 plant species from the literature. There were 14 species in common between experiments and the literature. The REML procedure log e -transformed data and removed absolute differences in Sr concentrations arising from soil factors and exposure times to estimate mean relative Sr concentrations for 155 species. One hundred and forty-two species formed a group with a normal frequency distribution in mean relative Sr concentration. A nested hierarchical analysis of variance (ANOVA) based on the most recent molecular phylogeny of the angiosperms showed that plant species do not behave independently for Sr concentration but that there is a significant phylogenetic effect on mean relative Sr concentrations. Concentrations of Sr in non-Eudicots were significantly less than in Eudicots and there were significant effects on Sr concentrations in the dataset down the phylogenetic hierarchy to the family level. Of the orders in the dataset the Cucurbitales, Lamiales, Saxifragales and Ranunculales had particularly high Sr concentrations and the Liliales, Poales, Myrtales and Fabales particularly low Sr concentrations. Mean relative Sr concentrations in 60 plant species correlated with those reported elsewhere for Ca in the same species, and the frequency distribution and some phylogenetic effects on Sr concentration in plants were similar to those reported for Ca. This analysis of mean relative Sr concentrations in 155 plant species across the angiosperm phylogeny might be helpful for modelling 90 Sr in food chains, predicting radiological doses to flora, and selecting species for phytomonitoring and phytoremediation of 90 Sr.

“…The comparison between element ratios in the soil solution and in the exchangeable fraction can be used to determine sorption selectivities on the exchange complex (Veresoglou et al 1995). For example, a higher Sr/Ca ratio in the exchangeable fraction compared to that of the soil solution indicates a selectivity of the exchanger for Sr relative to Ca.…”

Evaluation of the mobility and discrimination of Ca, Sr and Ba in forest ecosystems: consequence on the use of alkaline-earth element ratios as tracers of Ca

A comprehensive understanding of Ca cycling in an ecosystem is desirable because of the role of this element in tree mineral nutrition and its status as a major base cation on the soil exchange complex. The determination of the origin of Ca in forests is particularly indicated in regard of important changes linked to acid inputs and intensive logging. Natural strontium isotopes are increasingly used as tracers of Ca in forest ecosystems for qualitative and quantitative assessments. Nevertheless this method is limited to relatively simple systems with two sources of nutrients. Some recent studies coupled Sr/Ca or Sr/Ba ratios to Sr isotopic measurements in order to solve more complex systems. Such method has however associated with it some uncertainties: this approach assumed that Ca, Sr and Ba behave similarly throughout the ecosystem and does not take into account the Ca biopurification processes occurring in some tree's organs which can alter element ratio. The present work focuses on two deciduous species covering large areas in Europe: European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.). In order to test the similarity of behaviour between Ca, Sr and Ba, their concentrations were measured extensively in the major compartments of two forest ecosystems. In parallel, the discrimination process inside tree organs was studied in 23 stands for beech and 10 stands for oak. We found that Sr and Ca behave similarly in all soil and tree compartments. By contrast, Ba and Ca appear to have contrasting behaviours, especially in streams, soil solution and soil exchange complex (no correlations between element concentrations). Sr/Ba and Ba/Ca ratios must therefore be used with care as tracer of Ca. The Ca biopurification is absent in roots and slight in bole wood but is large in bark, twigs and leaves. The discrimination factors (DF) between wood and leaves are characteristic of the two species studied and do not change significantly as a function of the soil Ca status (acidic or calcareous soils). Therefore, strontium-calcium DF can be used as a correction factor of the Sr/Ca ratio of leaves when this ratio is used in connection with Sr isotopic ratios. This correction allows to solve systems of tree nutrition with more than two sources of Ca.

“…Because of the linear and positive relationship of Sr and Ca concentrations in plants, Veresoglou et al (1995) proposed the use of the index transfer factor for Sr per species' Ca concentration instead of T.E for Sr to compare various soils according to their ability to supply plants with Sr when different plant species are grown in those soils. Transfer factors can be used to compare plant species in taking up radionuclides when grown in the same soil or to compare different soils in supplying of a particular species with a radionuclide.…”

Shoot Sr concentrations in relation to shoot Ca concentrations and to soil properties

This work was aimed to investigate whether shoot Sr concentrations of plant species are related to respective Ca concentrations and to soil properties and to compare the Sr-Ca observed ratios (OR), defined as the quotient of the ratios Sr/Ca in shoots and in the soil solution or in the extractable form, among species and soils. Ten pasture plant species were grown in pots (1-L volume) filled with eight soils differing in the various physicochemical characteristics. Each pot received 50 mg Sr except those of the soil with the highest cation exchange capacity (C.E.C.) that received 100 mg Sr per pot. For each soil, shoot Sr concentrations of species were linearly and positively related with the respective Ca concentrations. C.E.C, organic matter content and Ca in the soil solution or in the extractable form were the only soil properties that were related, all negatively, with shoot Sr concentrations. The ratio of extractable Sr and Ca was positively and linearly related with the ratio of Sr and Ca. in the soil solution. OR was affected by both species and soils. Most of OR values of all species in all soils ranged between 0.8 and 1.5, except for the grass Agrostis capillaris which had the highest values for most of soils. This indicates that Agrostis capillaris compared to other species, takes up proportionally more Sr than Ca.
