TERSANE致力于阐明古代非人为全球变化的后果，目的是预测人为气候变化对生物和生态系统的影响。我们的首要假设是，与过去海洋生物危机相关的气候相关压力源（CRS）的影响可能会对未来的海洋产生类似影响。TERSANE初始阶段的成功和悬而未决的问题促使我们申请续约：TERSANE 2.0。我们自己以前的工作和独立的新发展需要在TERSANE的第二阶段强调：空间模式，生物地球化学循环，基于机制的理解和建模。TERSANE 2将有9个项目，它们被组织在三个紧密相连的研究支柱中，每个支柱包括三个项目：(1)识别跨越二叠纪-三叠纪边界的CRS (2) CRS影响的时空模式(3)桥接时空尺度柱1将使用地球化学代理和地球系统建模来揭示显生宙最大的高温事件和大灭绝期间的确切环境变化。项目将以营养和碳循环、大陆风化和缺氧原因的强度为目标。温度、二氧化碳和pH值已经在第一阶段得到了解决。支柱2在时间序列背景下探讨CRS影响的空间格局。这里应用了古生物学方法和建模。项目的重点是温度变化作为范围移动和灭绝的触发因素。每个项目还将强调与柱1相连的二叠纪-三叠纪边界的模式。支柱3致力于探索时空尺度对CRS影响的作用。我们假设生理数据提供了在多个时间尺度上对CRS反应的机制理解。因此，我们将生理实验、跨多个时间尺度的体型动态和生物生态系统命运联系在一起。该支柱中的项目与支柱1和支柱2紧密相连。

TERSANE is dedicated to elucidating the consequences of ancient, non-anthropogenic global change with the aim to project the consequences of anthropogenic climate change on organisms and ecosystems. Our overarching hypothesis is that the impact of climate-related stressors (CRS) that were associated with past marine biological crises may serve as analogues for the future ocean. Success of the still ongoing initial phase of TERSANE and outstanding questions lead us to apply for a renewal: TERSANE 2.0. Our own previous work and independent new developments necessitate emphasizing in phase 2 of TERSANE: Spatial patterns, biogeochemical cycles, mechanism-based understanding, and modeling.TERSANE 2 will have nine projects, which are organized in three tightly connected research pillars each comprising three projects:(1) Identifying CRS across the Permian-Triassic boundary(2) Spatiotemporal patterns of CRS impacts(3) Bridging spatiotemporal scales Pillar 1 will use geochemical proxies and earth system modeling to reveal the exact environmental changes across the largest hyperthermal event and mass extinction of the Phanerozoic. Projects will target nutrient and carbon cycles, continental weathering, and the intensity of causes of anoxia. Temperature, CO2 and pH have already been addressed in phase 1. Pillar 2 explores the spatial pattern of CRS impacts in a time series context. Here paleobiological methods and modeling are applied. Projects focus on temperature change as a trigger of range shifts and extinction. Each project will also emphasize patterns across the Permian-Triassic boundary linking to pillar 1.Pillar 3 is dedicated to probing the role of spatiotemporal scales on CRS impacts. We hypothesize that physiological data provide the mechanistic understanding for CRS responses on multiple time scales. Consequently, we link physiological experiments, body size dynamics across multiple time scales and organismic-ecosystem fates in this pillar. Projects in this pillar are tightly linked to both pillars 1 and 2.
