Workshop to Establish a Collaborative Global Experiment to Understand Coregonid Adaptive Response to Changing Thermal Regimes

全球范围内的鱼类数量正在减少。虽然下降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，因为随着环境变化，湖泊经历了冰覆盖的减少和显着的热变暖。现在需要的是一项全球协调的实验，以测试这些下降的原因。提供资金支持美国参加为期两天的国际研讨会，以设计和协调一项跨纬度、跨大陆的实验，以评估淡水白鱼(Coregoninae亚科)适应全球纬度温度和栖息地变化的能力。研讨会参与者将设计一项大型共同实验，以确定全球范围内湖泊温度和冰盖变化的原因和后果。该研讨会将提供一个独特的机会，设计和实施一项国际合作全球规模实验，以评估全球温度制度变化对通过一个关键淡水鱼家族的遗传和表观遗传变化适应和可塑性对生活史、生理和表型变化的作用。这将是第一个旨在评估广泛纬度梯度上不断变化的热状况的实验，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，可以整合和鼓励采用生态和分子方法，以增进和加强对环境变化对全球鱼类种群的影响的了解。除了这项研究的直接渔业管理影响外，它还将成为参与研究的研究生和早期职业教师在团队科学方面的重要培训经验。该研讨会是美国大学、联邦机构和法国国家农业研究所的联合伙伴关系，有来自13个国家的25名参与者。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
