cobalt; copper; hyperaccumulators; mesic conditions; models; niches; soil; soil toxicity; toxicity; vegetation; Republic of the Congo
Abstract:
... Ecological niche modelling helps us to understand the spatial assembly of species in heterogeneous environments. Three patterns have been widely reported in the research literature regarding the relationship between realised niches and macronutrient concentration gradients: (1) species’ optima are unevenly distributed, with a higher frequency in mesic conditions; (2) species’ response curves are n ...

Abstract:
... In Katanga (southeastern Democratic Republic of Congo), the flora of copper and cobalt deposits is highly threatened by mining. Until mining activity ceases and restoration can take place, seed banking is one of the strategies to be considered for the conservation of these metallophytes of which 32 are strict endemics. In the tropics, however, many species have recalcitrant (desiccation-sensitive) ...

Abstract:
... BACKGROUND: Plants that accumulate metal and metalloid trace elements to extraordinarily high concentrations in their living biomass have inspired much research worldwide during the last decades. Hyperaccumulators have been recorded and experimentally confirmed for elements such as nickel, zinc, cadmium, manganese, arsenic and selenium. However, to date, hyperaccumulation of lead, copper, cobalt, ...

Abstract:
... Populations of medicinal plants growing on serpentines and their respective soils were analyzed for Fe, Ni, Mn, Cr, Co, Cd, Cu, Zn, and Pb using inductively coupled plasma atomic emission spectrometry. Aqua regia extraction and 0.43 M acetic acid extraction were used for the quantification of pseudototal and bioavailable fractions, respectively, of elements in soil and nitric acid digestion for de ...

Abstract:
... This study was conducted to determine the uptake of elements (Ag, Al, As, Ca, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, P, S, Sb, Tl, U, W, Zn) by native gorse (Ulex europaeus) and heather (Calluna vulgaris), growing on abandoned tailings, Carnon Valley, Cornwall, UK. The metalliferous tailings are particularly As-rich (0.11–0.59wt% As) and contain acid-generating sulfides (pH 3.36–6.59). Since abandonment ...

Abstract:
... The aim of this study was to assess the accumulation of seven heavy metals (lead, cadmium, copper, zinc, chrome, nickel and cobalt). The investigations were conducted on twelve genotypes of willows which grow in the Potasze Forest Division Salicarium. The analysis facilitated quantification of concentrations of selected metals in plants and their comparison in relation to sorption ability of each ...

Abstract:
... The efficiency of the absorption from the medium and accumulation by plant of ions of the heavy metals depends on many factors including plant age and its genotype. The heavy metals accumulation by 1-, 2- and 3-year-old plants was studied in the aspect of reclamation and revitalization effectiveness of demoted areas. Results of this study answer the question concerning the accumulation of seven he ...

Abstract:
... Rhizosphere microorganisms harboring nickel hyperaccumulators, Rinorea bengalensis (Wall.) O. K. and Dichapetalum gelonioides ssp. andamanicum (King) Leenh. endemic to serpentine outcrops of Andaman Islands, India, were screened for their tolerance and accumulation of Ni. The rhizosphere soils from both the plants were rich in total and available Ni along with Co, Cr, Fe and Mg but poor in microbi ...

Abstract:
... Metal concentrations have been determined in shoots of 12 species considered as Cu and/or Co hyperaccumulators, collected from five subpopulations in a Cu/Co mine in Katanga. Samples have been subjected to three cleansing protocols (water, alconox, alconox + EDTA). Cu/Co concentrations were significantly higher when demineralised water was used to wash samples compared to more aggressive solutions ...

Abstract:
... Nickel phytoextraction using hyperaccumulator plants offers a potential for profit while decontaminating soils. Although soil pH is considered a key factor in metal uptake by crops, little is known about soil pH effects on metal uptake by hyperaccumulator plants. Two Ni and Co hyperaccumulators, Alyssum murale and A. corsicum, were grown in Quarry muck (Terric Haplohemist) and Welland (Typic Epiaq ...
