Tersane致力于阐明古老的、非人为的全球变化的后果，目的是预测人为气候变化对生物和生态系统的后果。我们的总体假设是，与过去的海洋生物危机相关的气候相关应激因素(CRS)的影响可能类似于未来的海洋。仍在进行的Tersane初始阶段的成功和悬而未决的问题导致我们申请续签：Tersane 2.0。我们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将有九个项目，这些项目被组织在三个紧密相连的研究支柱中，每个研究支柱包括三个项目：(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)连接时空尺度支柱1将使用地球化学代理和地球系统模拟来揭示最大的超热事件和显生界大灭绝过程中准确的环境变化。这些项目将针对营养和碳循环、大陆风化以及缺氧原因的强度。第一阶段已经讨论了温度、二氧化碳和酸碱度。支柱二探讨了在时间序列背景下CRS影响的空间模式。这里应用了古生物学方法和模型。项目的重点是温度变化作为范围转移和物种灭绝的触发点。每个项目还将强调连接到支柱1的跨越二叠系-三叠系边界的模式。支柱3致力于探索时空尺度对CRS影响的作用。我们假设生理数据在多个时间尺度上为CRS反应提供了机制上的理解。因此，我们将生理实验、多个时间尺度上的身体大小动态以及这一支柱中的生物生态系统命运联系起来。这一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.
