In contrast, compositional stability increased with warming and was not affected by herbivory, revealing a decoupling between the two facets of ecosystem stability under global change. Indeed, functional and compositional stability were positively related under ambient conditions but both became non significantly related under warming. Herbivory primarily affected community structure by reducing dominant species abundance and decreasing species asynchrony, whereas warming mainly decreased it by decreasing species asynchrony.</p><p dir="ltr"><b>Synthesis.</b> Our findings highlight that warming not only can affect ecosystem stability, but also shift the importance of control mechanisms from dominance to asynchrony, decoupling different ecosystem stability facets. Understanding how drivers of global change may interact is critical to anticipating change and managing natural ecosystems in an increasingly anthropogenic world. </p> 2025-09-26T14:01:03Z Dataset Dataset 10.6084/m9.figshare.30219025.v3 https://figshare.com/articles/dataset/Warming_modulates_the_effect_of_consumers_on_ecosystem_stability_Data_and_script/30219025 CC BY 4.0
