Facultative nitrogen fixation by legumes in the central Congo basin is downregulated during late successional stages

Abstract

Article first published online: 10 March 2016 ; The contribution of the legume community to the nitrogen cycle during natural forest regeneration remains poorly understood. We systematically assessed the changes in abundance and nodulation status of all legumes, across taxa and plant types, in a forest succession gradient in the Equateur Province of the Democratic Republic of the Congo. Our results clearly show that symbiotic N2 fixation is downregulated during late successional stages. ; Peer Review
