The study of periphery uniqueness and balance in ecological networks

Abstract: The study of ecological networks is crucial for modern conservation biology, addressing habitat fragmentation and biodiversity loss, especially in complex regions. These networks, including corridors, sources, and nodes, are key for species movement and ecosystem functioning. The Periphery Analysis Model (PAM) is introduced as a new approach to study the periphery of these networks, focusing on peripheral nodes' role in environmental change response and network resilience. PAM, drawing from graph theory, complex network analysis, and landscape ecology, uses the Periphery Uniqueness Index (PuI) and the Periphery Balance Index (PbI) to measure peripheral nodes' attributes and balance. It also offers derived indices for a detailed understanding of the periphery's influence. By revealing the periphery's defining characteristics, PAM enhances knowledge of ecological networks' structural features, providing insights for biodiversity, connectivity, and ecosystem health. The research encourages integrating PAM into conservation strategies to inform policy for ecosystem preservation amid environmental challenges.
