Research Priorities for Conservation of Metallophyte Biodiversity and their Potential for Restoration and Site Remediation
Plants that have evolved to survive on metal-rich soils-metallophytes-have key values that must drive research of their unique properties and ultimately their conservation. The ability ofExpand

Metallophytes: the unique biological resource, its ecology and conservational status in Europe, central Africa and Latin America
Metalliferous soils provide very restrictive habitats for plants due to phytotoxicity, resulting in severe selection pressures. Species comprising heavy-metal plant communities are geneticallyExpand

Phytostabilization of copper mine tailings with biosolids: implications for metal uptake and productivity of Lolium perenne.
A greenhouse pot experiment was conducted to evaluate the feasibility of using biosolids and Lolium perenne for the phytostabilization of copper mine tailings and to evaluate the patterns of metalExpand

Effect of soil copper content and pH on copper uptake of selected vegetables grown under controlled conditions.
A one-year greenhouse experiment was conducted to study the transfer of copper from contaminated agricultural soils to edible and nonedible structures of lettuce, tomato, and onion plants. StudyExpand

Micro-spatial variation of soil metal pollution and plant recruitment near a copper smelter in Central Chile.
Soil chemical changes produced by metal smelters have mainly been studied on a large scale. In terms of plant survival, determination of small scale variability may be more important because lessExpand

Soil physicochemical factors as environmental filters for spontaneous plant colonization of abandoned tailing dumps
Abandoned tailing dumps (ATDs) offer an opportunity to identify the main physicochemical filters that determine colonization of vegetation in solid mine wastes. The current study determined the soilExpand

Influence of copper on root exudate patterns in some metallophytes and agricultural plants.
A hydroponic experiment was carried out to determine the root exudation patterns in two Cu-metallophytes (Oenothera picensis and Imperata condensata) and two agricultural plants (Lupinus albus andExpand

Relationship between soil copper content and copper content of selected crop plants in central Chile.
A survey of copper levels in agricultural soils of central Chile revealed two soil clusters-one with a mean copper level of 162 mg/kg and one with a mean copper level of 751 mg/kg of soil. Samples ofExpand
