TLDR
Data support hypotheses that a relationship exists between the mycorrhizal status of Cyperaceae and their habitat, and that AM have a positive role in plant tolerance to ultramafic soils (mineral nutrition and metal tolerance), and suggest the use of these pioneer plants with AM management as potential tools for nickel mine site rehabilitation in New Caledonia.Abstract:
In New Caledonia, a hot spot of biodiversity, plants from the Cyperaceae family are mostly endemic and considered pioneers of the nickel-rich natural serpentine ecosystem. The aim of the study was ...read more

Phosphorus-mobilization ecosystem engineering: the roles of cluster roots and carboxylate exudation in young P-limited ecosystems
Hans Lambers,John G. Bishop,Stephen D. Hopper,Stephen D. Hopper,Etienne Laliberté,Alejandra Zúñiga-Feest +5 more
TL;DR: In this paper, the authors argue that the significance of cluster roots and high carboxylate exudation in the development of young ecosystems is probably far more important than has been envisaged thus far, and suggest that diazotrophic species that colonize young soils with strong P-sorption potential should be considered for their positive effect on P availability.

Occurrence of arbuscular mycorrhizal fungi in mining-impacted sites and their contribution to ecological restoration: Mechanisms and applications
TL;DR: Mining activities generally decrease topsoil and vegetation, reduce soil biodiversity, and yield extremely harsh environmental conditions, which limit natural revegetation and soil restorat... as discussed by the authors.

Diverse communities of arbuscular mycorrhizal fungi inhabit sites with very high altitude in Tibet Plateau
TL;DR: It is suggested that a diverse AMF flora is present in the Tibet Plateau, comprising both potentially habitat-selective and generalist fungi.

Arbuscular mycorrhizal symbiosis alleviates drought stress imposed on Knautia arvensis plants in serpentine soil
TL;DR: The role of AM symbiosis in plant drought tolerance under serpentine conditions was documented, but the potential of AMF to alleviate drought stress was limited beyond a certain threshold, as indicated by a steep decline in mycorrhizal growth dependence and phosphorus uptake benefit and a concomitant rise in proline concentrations in the roots of mycor rhizal plants at the highest drought intensity.

The role of macrophytes in wetland ecosystems
TL;DR: The most widely accepted macrophyte classification differentiates between freely floating macrophytes and those attached to the substrate, with the attached, or rooted macrophystes further divided into three categories: floating-leaved, submerged and emergent as discussed by the authors.

Biodiversity hotspots for conservation priorities
Norman Myers,Russell A. Mittermeier,Cristina G. Mittermeier,Gustavo A. B. da Fonseca,Jennifer Kent +4 more
TL;DR: A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed.

The Mineral Nutrition of Higher Plants
M. H. Martin,H. Marschner +1 more
TL;DR: This chapter discusses the relationship between Mineral Nutrition and Plant Diseases and Pests, and the Soil-Root Interface (Rhizosphere) in Relation to Mineral Nutrition.
Book
Mineral Nutrition of Higher Plants
TL;DR: In this article, the authors discuss the relationship between mineral nutrition and plant diseases and pests, and diagnose deficiency and toxicity of mineral nutrients in leaves and other aerial parts of a plant.

Phylogenetic distribution and evolution of mycorrhizas in land plants
B. Wang,Yin Long Qiu +1 more
TL;DR: A survey of 659 papers mostly published since 1987 was conducted to compile a checklist of mycorrhizal occurrence among 3,617 species (263 families) of land plants and a plant phylogeny was then used to map the mycor rhizal information to examine evolutionary patterns.

R. E. Koske,J.N. Gemma +1 more
TL;DR: A modified technique for staining roots to detect VA mycorrhizas is described and success has been achieved with angiosperm, fern, lycopod and psilophyte roots and bryophyte.
