This study systematically analyzes the primary drivers of species endangerment and explores the application of ecological and conservation biology theories in endangerment research. Based on island biogeography theory, metapopulation theory, and ecological niche theory, it examines the impacts of habitat fragmentation, climate change, and population decline on species survival. Furthermore, it discusses key endangerment mechanisms, including genetic diversity loss, food web disruptions, reduced reproductive success, and physiological and behavioral changes induced by environmental pressures. Using the global amphibian crisis as a case study, this study illustrates how environmental changes exacerbate species decline, summarizing the threats posed by disease, climate change, and habitat destruction to amphibian populations. Additionally, it proposes a series of mitigation strategies, including habitat restoration, captive breeding, genetic interventions, policy and regulatory frameworks, and community-based conservation approaches. This study aims to provide policymakers and conservation practitioners with systematic theoretical support and practical guidance to advance global biodiversity conservation.
