August 2018 – New Phytologist special collection: Plant allocation in a changing world. Guest-edited by Henrik Hartmann, Michael Bahn, Andrew Richardson, and Mariah Carbone. Submission instructions here.
Targeted questions: 1) what drives carbon allocation in plants and ecosystems? 2) what is the fate of newly assimilated carbon? 3) what determines the allocation of nonstructural carbon to growth, metabolism and storage? 4) how does carbon allocation affect nutrient and water relations in plant and ecosystems? and 5) how do allocation patterns change under changing environmental conditions and what are the consequences for biogeochemical cycles?
