Intraspecific variation in calcium and strontium accumulation / depuration in an epigeic earthworm species

Metals in organic and conventional wheat flours determined by an optimised and validated ICP‐MS method

“…The average Ca/Mg ratio was by 22.5% higher in Conv compared with Org wheat flours as a consequence of higher Mg content in Org samples. Ca has also many common properties with Sr, which is considered as its metabolic analogue (West et al. , 2001).…”

“…The average Ca ⁄ Mg ratio was by 22.5% higher in Conv compared with Org wheat flours as a consequence of higher Mg content in Org samples. Ca has also many common properties with Sr, which is considered as its metabolic analogue (West et al, 2001). However, it has been suggested that bioaccumulations of these two elements are different, which is related to the ability of plants to selectively control the uptake of Sr and Ca (Morgan et al, 2002).…”

Ecology, Soils, and the Left

“…For example, root composition diversity within cabbage has been found to lead to greater or lesser numbers of nematodes without altering the soil food web, but the analysis is confined to interspecific relations (Kabouw et al 2010). In contrast, West et al (2001) report that different populations from the same earthworm species (Lumbricus rubellus) excreted different amounts of strontium, which over time could affect that element's distribution in soil (see also Sizmur et al 2011).…”
