Partitioning of Major and Trace Elements in a Stand of the Nickel Hyperaccumulator Rinorea cf. bengalensis in Borneo

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Rinorea cf. bengalensis is a tropical nickel hyperaccumulator plant that can be dominant in forests locally. We investigated the partitioning of major and trace elements in a stand of R. cf. bengalensis in Borneo. Hyperaccumulators have a large impact on the cycling of Ni and other elements in their ecosystem. ABSTRACT Rinorea cf.
