Populations of fish are declining across the globe. While the specific causes of the declines are unknown it is suspected that they are related to changing ice and water temperature as lakes have experienced reduced ice cover and significant thermal warming in response to environmental change. What is needed is a globally coordinated experiment to test the causes for these declines. Funds are provided to support US participants in a two-day international workshop to design and coordinate a cross-latitudinal, cross-continental experiment to evaluate the ability of freshwater whitefishes (subfamily Coregoninae) to adapt to changing temperature and habitat changes across global latitudes. Workshop participants will design a large-scale common experiment to identify the causes and consequences of global scale changes in lake temperature and ice cover.This workshop will provide a unique opportunity to design and implement an international collaborative global scale experiment to assess the role of changing global thermal regimes on the role of adaptation and plasticity to changes in life history, physiology, and phenotype through genetic and epigenetic changes of a key freshwater fish family. It will be the first experiment designed to evaluate changing thermal regimes across a broad latitudinal gradient and provide a unique forum to ensure standardization, coordinated implementation, and robust data management. The workshop offers an excellent opportunity to integrate and encourage ecological and molecular approaches to enhance and strengthen understanding of environmental change impacts on global fish populations. Besides the direct fisheries management impacts of the research, it will serve as a significant training experience in team science for the participating graduate students and early career faculty. The workshop is a joint partnership between universities and federal agencies in the USA and French National Institute for Agricultural Research, with 25 participants from 13 countries.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.

全球鱼类数量正在下降。虽然减少的具体原因尚不清楚，但人们怀疑它们与冰和水温的变化有关，因为湖泊因环境变化而经历了冰盖减少和显著的热变暖。我们需要的是一项全球协调的实验，以检验这些下降的原因。资助美国参加为期两天的国际研讨会，设计和协调一个跨纬度、跨大陆的实验，以评估淡水白鱼（Coregoninae亚科）适应全球纬度变化的温度和栖息地变化的能力。研讨会参与者将设计一个大规模的共同实验，以确定全球尺度湖泊温度和冰盖变化的原因和后果。本次研讨会将提供一个独特的机会来设计和实施一个国际合作的全球规模的实验，通过遗传和表观遗传的变化来评估全球热制度的变化对一个关键淡水鱼家族的生活史、生理和表型变化的适应和可塑性的作用。这将是第一个旨在评估在广泛的纬度梯度上不断变化的热状态的实验，并提供一个独特的论坛，以确保标准化、协调实施和强大的数据管理。讲习班提供了一个极好的机会，可以综合和鼓励生态和分子方法，以增进和加强对环境变化对全球鱼类种群影响的了解。除了研究对渔业管理的直接影响外，它还将为参与研究的研究生和早期职业教师提供重要的团队科学培训经验。该讲习班是美国大学和联邦机构与法国国家农业研究所之间的联合伙伴关系，有来自13个国家的25名与会者。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
