Human activities have significantly altered coastal ecosystems worldwide. The phenomenon of shifting baselines syndrome (SBS) complicates our understanding of these changes, masking the true scale of human impacts. This study investigates the long‐term ecological effects of anthropogenic activities on New Zealand's coastal ecosystems over 800 years using fish otolith microchemical profiling and dynamic time warping across an entire stock unit. Results reveal a shift in snapper (Chrysophrys auratus ; Sparidae) habitat‐use behaviour, transitioning from low‐salinity estuarine environments to higher‐salinity habitats, correlating with ongoing land‐use changes. This shift coincided with New Zealand's localised Industrial Revolution, which served as a tipping point for widespread ecosystem transformation. By comparing current coastal fish movement profiles with historical baselines, we provide evidence to address SBS and guide conservation strategies. Re‐establishing pre‐industrial habitat‐use behaviours in snapper will indicate successful habitat restoration, promoting overall ecosystem connectivity and resilience. Our findings enable more effective habitat restoration measures and sustainable management practices, informing policies for maintaining coastal biodiversity and ecosystem function.

克服不断变化的基线:古生物学行为揭示工业革命是转折点
人类活动极大地改变了全世界的沿海生态系统。基线变化综合症 (SBS) 的现象使我们对这些变化的理解复杂化,掩盖了人类影响的真实规模。本研究使用鱼类耳石微化学分析和整个种群单位的动态时间扭曲,调查了 800 多年来人为活动对新西兰沿海生态系统的长期生态影响。结果显示鲷鱼 (Chrysophrys auratus;Sparidae) 栖息地利用行为,从低盐度河口环境过渡到高盐度栖息地,与持续的土地利用变化相关。这种转变与新西兰的局部工业革命相吻合,工业革命是广泛生态系统转型的转折点。通过将当前的沿海鱼类运动概况与历史基线进行比较,我们为解决 SBS 问题提供证据并指导保护策略。重新建立鲷鱼工业化前栖息地使用行为将表明栖息地恢复成功,促进整体生态系统的连通性和复原力。我们的研究结果使更有效的栖息地恢复措施和可持续管理实践成为可能,为维护沿海生物多样性和生态系统功能的政策提供信息。
