Advances in Ecosystem Regime Shifts and Tipping Mechanisms: A Comprehensive Review

doi:10.7523/j.ucas.2025.043

Abstract

Abstract: Regime shifts and their critical mechanisms in ecosystems are the critical issue in ecological research, with profound implications for predicting ecological risks under global change. This review systematically synthesizes the theoretical advances in alternative stable state (ASS) of ecosystem multi-stability, focusing on three key dimensions: (1) micro-macro process coupling, (2) mechanisms of threshold response, and (3) the role of regulatory nodes in ecosystem resilience. By integrating methodologies such as ASS theory, potential landscape modeling, and bifurcation analysis, we highlight how climate change and anthropogenic activities are driving critical ecosystems (e.g., coral reefs, Amazon rainforest, Arctic permafrost) toward tipping points, while hysteresis effects and irreversible potentials exacerbate recovery challenges. Emerging approaches combining network theory and energy (carbon) flux analysis offer novel insights for cross-scale early warning, yet bridging micro-scale mechanisms with macro-scale patterns remains a critical challenge. This review provides a theoretical framework for ecological threshold management and underscores the urgent need for interdisciplinary approaches to address planetary-scale regime shift risks.

Key words: Ecosystem regime shifts, tipping point, Stability, Hysteresis effects, Food webs
