At the Earth's surface, calcium (Ca) is a critical element at a variety of scales: it is soluble in
natural waters, a biological nutrient, and a major constituent of the dominant mineral sink for …

Primary productivity of forest ecosystems depends on the availability of plant‐essential
mineral nutrients. Because nutrient demand of trees often exceeds nutrient supply from rock …

Calcium is one of the most important mobile metals that can migrate easily between major
geochemical reservoirs at the Earth's surface; the hydrosphere and the biosphere and crust …

Weathering and ecosystem nutrition are intimately linked through the supply of fresh mineral
nutrients from regolith and bedrock (the “geogenic nutrient pathway”). However, the …

This study reports radiogenic Sr isotope ratios (87 Sr/86 Sr), stable Sr isotope ratios (δ 88/86
Sr), and major ion concentrations for river, rock, sediment, soil, and plant samples collected …

A Mg isotope study of sugar maple (Acer saccharum Marsh.) in a field site in southern
Québec, Canada, and seedlings grown in sterile soil substrate in the laboratory, both …

Calcium (Ca) is the fourth most abundant element in mineral nutrition and plays key
physiological and structural roles in plant metabolism. At the soil-water-plant scale, stable …

Acid deposition is widespread in Japan, but acidification of stream water is rare in forest
ecosystems. Bedrock‐derived cations, including those released into the soil by weathering …

In archaeological mobility studies, non-local humans and animals can be identified by
means of stable strontium isotope analysis. However, defining the range of local 87 Sr/86 Sr …

Calcium and strontium isotope ratios were used to identify Ca sources for bulk soil, soil
solutions and runoff in the stressed forest ecosystems of Central Europe. All three study sites …
