How Combined Pairwise and Higher-Order Interactions Shape Transient Dynamics

Abstract

Understanding how species interactions shape biodiversity is a core challenge in ecology. While much focus has been on long-term stability, there is rising interest in transient dynamics-the short-lived periods when ecosystems respond to disturbances and adjust toward stability. These transitions are crucial for predicting ecosystem reactions and guiding effective conservation. Our study introduces a model that blends pairwise and higher-order interactions, offering a more realistic view of natural ecosystems. We find pairwise interactions slow the journey to stability, while higher-order interactions speed it up. This model provides fresh insights into ecosystem resilience and recovery, helping improve strategies for managing species and ecological disruptions.
