Other claims from this paper (14)
- Intervention effect P fertilization increased alder nodule biomass relative to controls.
- Intervention effect P fertilization increased alder N-fixation rates relative to controls.
- Intervention effect N fertilization lowered alder nodule biomass relative to controls.
- Intervention effect N fertilization lowered alder N-fixation rates relative to controls.
- Intervention effect Stand-level N inputs in +P plots exceeded +N plots by more than an order of magnitude.
- Association Nodule respiration and N-fixation rates were positively correlated in alder.
- Mechanism Alder increased carbon use efficiency when N fixation was up-regulated.
- Observation Two of eight identified Frankia OTUs were dominant.
- Association Fertilization explained significant differences in Frankia OTU composition.
- Observation Dominant Frankia OTUs responded similarly to up- and down-regulation treatments.
- Observation Dominant Frankia OTUs differed in carbon costs of N fixation.
- Intervention effect The most abundant subdominant Frankia OTU failed to increase N fixation in +P plots.
- Mechanism Manipulating Frankia assemblages was suggested as an alder adaptation across different environments.
- Mechanism Alder changes in carbon allocation to nodules appear to drive and respond to environmental heterogeneity.
