Other claims from this paper (8)
- Association Eucalyptus urophylla seedlings emitted about 50 % more isoprene than field-grown trees.
- Association Eucalyptus urophylla seedlings were enriched in cyclic monoterpenes such as α-pinene and 1,8-cineole.
- Association Field-grown Eucalyptus urophylla trees shifted toward highly reactive acyclic monoterpenes.
- Observation In field-grown trees β-ocimenes accounted for over 85 % of the terpene flux.
- Observation Field-grown trees showed a double rise in sesquiterpenes.
- Association Tree age had a significant impact on both the magnitude and the speciation of BVOC emissions.
- Observation The authors infer that one-third of the entries in global emission-factor compilations, derived from seedling studies, are likely inappropriate as surrogates for natural forest emissions.
- Recommendation The authors call for systematic, large-sample, branch-level measurements of adult trees to produce representative emission factors.
