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 Supplementary Material File (guichard_ea_ms_full.pdf) Download 1.29 MB Information & Authors Information Version history V1 Version 1 23 June 2025 Copyright This work is licensed under a Non Exclusive No Reuse License.
