Native tree seedling interactions with variations in edaphic properties in upland boreal forest restoration
Bibliographic record
Abstract
The boreal forest is a vast circumpolar ecosystem covering approximately 11 % of terrestrial land globally. The Canadian boreal forest is rich in natural resources such as lumber, minerals, and oil, and therefore is heavily managed by humans in some regions. Surface mining for oil sands deposits in northern Alberta requires active forest reclamation which presents a unique challenge given the severity of this type of disturbance. I investigated the influence of organic- and mineral-dominated reclamation soils on native tree seedling establishment. Specifically I determined (1) the community recovery of important belowground mutualists, ectomycorrhizal fungi, and their influence on seedling growth in these soils using outplanted seedlings of Populus tremuloides, Pinus banksiana, and Picea glauca. In addition, I examined (2) the influence of low soil temperature during budflush for seedlings of Populus tremuloides. I found (1) the species of tree seedling was more important in determining ectomycorrhizal fungal community composition rather than reclamation soil type, and that (2) low soil temperature during budflush of Populus tremuloides seedlings results in lower growth. Based on these results I suggest that using a diversity of tree seedlings for outplanting onto reclamation areas may recover a more diverse ectomycorrhizal fungal community, and that efforts should be made to monitor the peat content and depth of reclamation soils to prevent the creation of low spring soil temperatures that may be detrimental to the establishment and growth of Populus tremuloides seedlings.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
