Serpentine Soils as Media for Plant Growth

2007
Plants and animals require water, energy sources, and nutrients to make tissues and perform vital functions. The primary source of energy is the sun. Green plants use solar energy to manufacture organic compounds that are later oxidized to produce energy for both plants and animals.

Calcareous and serpentine soils and their vegetation

1987
In these cases a very conspicuous ecological pattern is imposed by substrate on vegetation. This pattern virtually transcends all other environmental factors, and thus in some ways resembles the effect of phosphate depletion on Australian vegetation (see Chapter 16).

Serpentine Soil Distributions and Environmental Influences

2007
Serpentine soils occur in all but one of the twelve orders (Alexander 2004b), which is the highest level in Soil Taxonomy (Soil Survey Staff 1999), the primary system of soil classification utilized in this book (appendix C). They occur in practically every environment from cold arctic to hot tropical and from arid to perhumid (always wet).

Diversity of Cenococcum geophilum isolates from serpentine and non-serpentine soils

Mycologia, 2001
Serpentine soils are characterized by a dis- proportionate level of Mg in relation to Ca and often contain phytotoxic levels of available Ni. Both of these factors may represent stresses to plants and fun- gi colonizing these soils. Ectomycorrhizal fungi play important roles in tree biology, and ecotypic adap- tation in these fungi may be critical to ...

Characterization of nickel‐resistant bacteria isolated from serpentine soil

Environmental Microbiology, 2001
In the present study, heterotrophic nickel‐resistant bacteria were isolated and characterized from three different serpentine outcrops in central Italy populated by the nickel‐hyperaccumulating plant Alyssum bertolonii .

Facilitation allows plant coexistence in Cuban serpentine soils

Plant Biology, 2013
AbstractSerpentine soils represent stressful habitats where plants have to cope with heavy metals, moisture limitation and low nutrient availability. We propose that facilitation is an important mechanism structuring plant communities under such stressful conditions.

Soil and Vegetation of the Keen of Hamar Serpentine, Shetland

The Journal of Ecology, 1987
SUMMARY (1) The Keen of Hamar, Shetland, is an important lowland British serpentine site which has many plant rarities and extensive areas of sparsely colonized rock debris. (2) The site has been subjected to various forms of human disturbance but these do not account for the extent of the debris.

Heavy metals in soils and plants of serpentine and industrial sites of Albania

Science of The Total Environment, 1998
Soils developed on serpentine rocks cover a large area in Albania which contains large reserves of iron, nickel, chromium and copper and is characterised by a high density of mines and metal smelters. This work was conducted to study the flora associated with serpentine and former industrial and mining sites in Albania. Eight sites were investigated in

EFFECT OF SOIL REACTION ON UPTAKE OF NICKEL FROM A SERPENTINE SOIL

Soil Science, 1956
In pot experiments with a serpentine soil, increase in soil pH, whether produced by CaCO/sub 3/ or Na/sub 2/CO/sub 3/, was found to reduce Ni extractable by ammonium acetate and also that absorbed by oat plants. Laboratory studies were made of the recovery of Ni added to a granitic soil limed by either CaCO/sub 3/ or Na/sub 2/CO/sub 3/.

Metallophytes of Serpentine and Calamine Soils – Their Unique Ecophysiology and Potential for Phytoremediation

2017
Abstract For years, metallophytes of both natural and human-influenced metalliferous soils have focussed considerable attention due to their unique appearance and ability to colonize often extremely harsh habitats. A majority of metal-contaminated areas comprise serpentine (ultramafic, rich in Ni, Cr and Co) and calamine (rich in Zn, Pb and Cd) soils
