The dual role of detritus as resource and habitat: integrating non-trophic processes to ecosystem dynamics
Bibliographic record
Abstract
The diversity of ecological interactions, trophic and non-trophic, is central to understand the assembly of communities. However, we have yet to integrate non-trophic to ecosystem-level processes such as recycling or habitat provisioning. Here we study a simple ecosystem model where the dual role of detritus as both resource and habitat allows defining ecosystem engineering from non-trophic processes interacting with the cycling of matter at the ecosystem level. Our results show how habitat and resource limitation of consumer growth from detritus can affect ecosystem stability. We further predict that non-trophic processes can stabilize ecosystems via (i) asynchrony between trophic and non-trophic interactions, (ii) weak trophic interactions emerging from non-trophic feedbacks, and (iii) coupling between non-trophic and recycling processes that control top-down vs bottom-up trophic regulation. Our results show ecosystem dynamics provides the relevant context to study the interplay between trophic and non-trophic processes

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.
