between soft and mineralized tissues as a monitor of calcium
use in vertebrates. PNAS 96: 13709–13713

doi:10.1029/2005GL022746, 2005
A paper on the Ca cycle in soils and trees. Short and sweet.

natural calcium isotope (44Ca/40Ca) fractionation in urine as a
proxy for the human body calcium balance. Bone
