Question
In Eastern Canada, wildfires turn Picea mariana forests into Kalmia angustifolia dominated heath or P. mariana forest depending on burn severity. These alternate end‐points of succession provide an opportunity to test assumptions concerning alternate successional trajectories dominated by distinct plant functional groups. Disturbance effects on functional diversity (FD) have been studied...
Using black spruce (Picea mariana)-Kalmia angustifolia dominated communities of eastern Canada we tested the hypothesis that habitat filter pre-empts biotic filter as a community structuring force in early post-fire succession leading to Kalmia dominated heath. We considered post-fire seedbed as an abiotic (habitat) filter and post-fire aboveground biomass of dominant plants as a biotic filter. First...
