  abstract = {{T}he hyperaccumulator {P}ycnandra acuminata is a {N}ew {C}aledonian rainforest tree known to have the highest concentration of nickel in any living organism, with 25 wt% nickel in its latex. {A}ll trees (with a diameter of >10 cm) and soil profiles in a 0.25-hectare permanent plot were sampled to assess the biogeochemical compartmentalisation of nickel in a dense stand of {P}. acuminata trees. {N}ickel stable isotope analysis permitted insights into the cycling of nickel in this ecosystem. {T}he total tree biomass of the plot was calculated to be 281 tonnes ha(-1), which contained 0.44 kg of cobalt, 49.1 kg of manganese, 257 kg of nickel and 6.76 kg of zinc. {N}ickel stable isotope analysis identified the biotic origin of the nickel in the soil upper layers, with {P}. acuminata shoots enriched in lighter nickel isotopes. {T}he delta {N}i-60 latex signature suggests that long-distance transport, radial xylem and phloem loading are at play in {P}. acuminata.},
