Marine biological communities contain multiple species that interact to form dynamic networks. These networks profoundly shape the coexistence of species and function of marine ecosystems. Climate change and species invasions threaten these networks at planetary scales. Predicting how marine communities respond to these changes is challenging because the disturbances they cause can affect the interwoven networks in unexpected ways. In addition, marine organisms may adapt to those perturbations. For example, they may adapt to eat new species, be better defended from predators, or to assimilate nutrients more effectively from oceanic currents. This project will develop new models to predict how environmental changes influence organisms and how they adapt to those changes. These models will integrate empirical data and the fossil record of three of the most productive coasts in the world,- the Californian, Chilean, and South African coast. The fossil record of these marine communities will inform the models of how these communities responded to climate change and species invasions thousands of years ago. This project will also offer workshops for early career scientists once a year. This project also supports diversity initiatives through the Center for the Advancement of Multicultural Perspectives on Science.This project will bring together scientists from the fields of network ecology, oceanography, paleontology, evolution, theoretical ecology, and community ecology. Together, they will develop new network models to evaluate how functional-trait responses to climate change and species invasions may affect the resistance and resilience of marine ecosystems to multiple environmental stressors. At ecological timescales, this project will leverage long-term data of biological and physical variables. At evolutionary timescales, this project will leverage the historical paleontological record, which shows strong evidence of the role of climate change and species invasions in shaping the functional biodiversity of these systems. These models will allow the scientific community to test hypotheses on how functional biodiversity responds to environmental change from the organismal to the ecosystem level, at ecological and evolutionary timescales.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

海洋生物社区包含多种相互作用以形成动态网络的物种。这些网络深刻地塑造了物种的共存和海洋生态系统的功能。气候变化和物种入侵威胁着行星尺度上的这些网络。预测海洋社区如何应对这些变化是一项挑战，因为它们引起的干扰可能会以意想不到的方式影响交织的网络。此外，海洋生物可以适应这些扰动。例如，它们可能适应食用新物种，更好地防御捕食者，或者从海洋流中更有效地吸收营养。该项目将开发新的模型，以预测环境变化如何影响生物以及它们如何适应这些变化。这些模型将整合经验数据和世界上三个最有效的海岸的化石记录，即加利福尼亚州，智利和南非海岸。这些海洋社区的化石记录将为这些社区如何应对气候变化和数千年前的物种入侵的方式告知模型。该项目还将每年为早期职业科学家提供讲习班。该项目还通过基于科学的多元文化观点的发展中心支持多样性倡议。该项目将把网络生态学，海洋学，古生物学，进化论，理论生态学和社区生态学领域的科学家汇集在一起​​。他们将共同开发新的网络模型，以评估功能性特征对气候变化的反应以及物种入侵可能影响海洋生态系统对多个环境压力源的抵抗力和弹性。在生态时期，该项目将利用生物学和物理变量的长期数据。在进化时段，该项目将利用历史古生物学记录，该记录显示了气候变化和物种入侵在塑造这些系统功能生物多样性中的作用的有力证据。这些模型将使科学界能够在生态和进化时期对环境变化的响应来检验假设对环境变化的反应。该奖项反映了NSF的法定任务，并通过使用该基金会的智力优点和广泛的影响来评估Criteria criteria criteria criteria审查了NSF的法定任务。
