“…Mg and Ni leaching would result in a higher Ca:Mg molar ratio and lower Ni concentration (less chemical stress) than typical serpentine soils, as seen in this study. A similar weakening of the serpentine syndrome on forest soils has also been documented in coniferous forests of northern California (Alexander 1988). In that case, higher forest productivity on well developed, ancient soils was attributed to the progressive leaching of Mg and other heavy metals such as Ni.…”

Background and aims Soils derived from serpentinite (serpentine soils) often have low macronutrient concentrations, exceedingly low Ca:Mg molar ratios and high heavy metal concentrations, typically resulting in sparse vegetative cover. This combined suite of edaphic stresses is referred to as the "serpentine syndrome." Although several plant community-level studies have been conducted to identify the most important edaphic factor limiting plant growth on serpentine, the primary factor identified has often varied by plant community and local climate. Few studies to date have been conducted in serpentine plant communities of alpine or boreal climates. The goal of our study was to determine the primary limiting edaphic factors on plant community species composition and productivity (cover) in the alpine and boreal climate of the Western Alps, Italy. Methods Soil properties and vegetation composition were analyzed for several sites underlain by serpentinite, gabbro, and calc-schist substrates and correlated using direct and indirect statistical methods.

“…Serpentine soils, rich in iron, magnesium, and heavy metals such as chromium and nickel, have a suite of soil properties that differ from nonserpentine soils derived from metasedimentary rocks (Brooks 1987;Alexander 1988;O'Hanley 1996;Lee et al 2001;Oze et al 2004). The effect of these soil differences is a change in vegetation density and in woody plant species (Kruckeberg 2006).…”

Ectomycorrhizal communities of Quercus garryana are similar on serpentine and nonserpentine soils

Serpentine soils, rich in iron, magnesium, and heavy metals, select for unique plant communities and for endemic species. Because mycorrhizal fungi mediate the interaction between plants and soil, we hypothesized that distinct ectomycorrhizal fungi would colonize Quercus garryana roots on serpentine and nonserpentine soils. We sampled roots of Q. garryana on serpentine soils at two locations in the Klamath-Siskiyou Mountains of southwestern Oregon and identified ectomycorrhizas by morphological and molecular methods. The same six most abundant and most frequent mycorrhizal species, Cenococcum geophilum, Tuber candidum, Genea harknessii, Tomentella sp., Sebacina sp., and Inocybe sp., were found on serpentine and nonserpentine soils. Based on similarities calculated using the Sørensen index in Non-metric Multidimensional Scaling, mycorrhizal communities on serpentine and nonserpentine soils were not significantly different. This study showed that ectomycorrhizal species associated with Q. garryana exhibit edaphic tolerance and were neither reduced nor excluded by serpentinite or peridotite parent materials.

“…Previous studies have illustrated the importance of the following processes in ultramafic pedogenesis: (1) redistribution of Mg and Ni within soil profiles and below the solum (Rabenhorst et al 1988;Alexander 1988), (2) transfer of Fe and trace metals from silicate minerals to secondary Fe oxides and oxyhydroxides (Sasaki et al 1968;Mizota 1982;Miura et al 1988), and (3) alteration ofserpentine, chlorite and other minerals present in ultramahc rocks to vermiculite and smectite (\ilildman et al 1968; Ducloux et al 1976;Bain 1911).…”
