Human health and well-being are intimately tied to surface freshwater availability and quality. Providing adequate and safe freshwater requires management of freshwater systems like lakes, rivers, and ponds. Increasing environmental variability makes management more difficult and requires an understanding of how natural biological communities respond to change. Resilience, or the ability to withstand changes to climate, is likely due to both diversity in species and individual characteristics. Species contain individuals that can be very different from one another, we suggest this diversity in characteristics (phenotype) is as important as the diversity of species in building climate resilience. This idea has rarely been evaluated experimentally or across space and time. This multi-institution, multi-disciplinary team will test the effects of changing climatic conditions on freshwater ecosystems. This collaboration combines technology (artificial intelligence and distributed computing) with biological theory to understand freshwater systems using observational, experimental, and modeling approaches. This interdisciplinary team will test ecological frameworks and explore resilience to environmental change. In ponds and lakes, body size is an aspect of phenotype that can determine the success of a predator or a competitor, where larger organisms are often more successful. Body size can also change in response to environmental conditions, and some animals are better able to adjust body size under favorable conditions. We hypothesize that communities with limited species diversity and individual variation will be less resilient, while communities that can maintain species diversity and individual variation will maintain high resilience and ecosystem services. We hypothesize that communities that maintain diversity and variation will do so by shifts in how species and individuals interact, controlled in part by changes in body size. In addition to predicting resilience of freshwater ecosystems under a changing climate, results of this study will provide managers and policy makers with a deeper understanding of the range of ecosystem changes to anticipate and enable targeted application of management actions and dollars to preserve ecosystem services for human well-being. The study will enhance the learning and research experience of STEM (Science, Technology, Engineering, and Math) students at Oregon State University, Gonzaga University, and Whitworth University by providing an experience in scientific collaboration using skills and information from different fields to solve a common problem. The team will conduct outreach and recruitment efforts to engage underrepresented groups, particularly tribal and migrant communities, via curriculum development, research participation, and the production of bilingual children's books that highlight Pacific Northwest freshwater ecosystems.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.

人类健康和福祉与地表淡水的供应和质量密切相关。提供充足和安全的淡水需要对湖泊、河流和池塘等淡水系统进行管理。日益增加的环境变异性使管理更加困难，需要了解自然生物群落如何应对变化。复原力，或抵御气候变化的能力，可能是由于物种和个体特征的多样性。物种包含可能彼此非常不同的个体，我们认为这种特征（表型）的多样性与建立气候适应力的物种多样性一样重要。这个想法很少被实验或跨越空间和时间评估。这个多机构、多学科小组将测试气候条件变化对淡水生态系统的影响。这项合作将技术（人工智能和分布式计算）与生物理论相结合，使用观测，实验和建模方法来了解淡水系统。这个跨学科的团队将测试生态框架，并探索对环境变化的适应能力。在池塘和湖泊中，身体大小是表型的一个方面，可以决定捕食者或竞争者的成功，其中较大的生物通常更成功。身体大小也会随着环境条件而改变，有些动物在有利的条件下能够更好地调整身体大小。我们假设，有限的物种多样性和个体变异的社区将是较低的弹性，而社区，可以保持物种多样性和个体变异将保持高弹性和生态系统服务。我们假设，保持多样性和变化的社区将通过改变物种和个体之间的相互作用来实现这一目标，而这在一定程度上是由身体大小的变化所控制的。除了预测气候变化下淡水生态系统的复原力外，本研究的结果还将使管理人员和决策者更深入地了解生态系统变化的范围，以预测和有针对性地应用管理行动和资金，为人类福祉保护生态系统服务。该研究将通过提供利用不同领域的技能和信息进行科学合作的经验，增强俄勒冈州州立大学、贡扎加大学和惠特沃斯大学STEM（科学、技术、工程和数学）学生的学习和研究经验。解决共同问题。该团队将通过课程开发、参与研究和制作突出太平洋西北部淡水生态系统的双语儿童读物，开展外联和招募工作，以吸引代表性不足的群体，特别是部落和移民社区。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
