R. M. de  aUptake and hyperaccumulation of Ni by ultramafic flora as a function of soil type and Ni availability (Barro Alto, GO, Brzil).  c2009  aOne lateritic soil and one saprolitic soil and their respective flora were sampled for chemical analysis. Results indicated that total Ni in sils varied from 0.7 to 1.2% whilst the chemical availability of Ni ranged from 60um to 650 um Ni g-1 of soil. Chemical composition of the soils in this area was consistent with the general chemical properties of typical ultramafic soils. About 23 different species were presented in each area and Ni content in their tissues varied from 18 to 2,140 mg Ni kg-1 DW. Finally, it was observed that plant diversity and Ni accumulation in plant tissues were strongly related to Ni availability observed in the soils.  aCerrado  aEspécies nativas  aRecuperação de área degradada1 aECHEVERRÍA, G.1 aAQUINO, F. de G.1 aMIRANDA, Z. de J.
