RoL: FELS Conference: A Fading Cryosphere Shifting Temperature and Stoichiometry in Mountain Lakes and Streams: A US-China Cooperative Workshop

该项目支持2019年4月在平头湖生物站(蒙大拿州)举办的讲习班，来自美利坚合众国的研究人员和中国参加了讲习班。冰冻圈是地球上冻结的部分，包括冰川冰、积雪和永久冻土。在世界各地，冰冻圈正在加速融化，包括在山区。这些变化很重要，因为山区为世界40%的人口供水。然而，在许多情况下，人们还没有很好地了解冰冻圈的变化如何影响湖泊和河流等水生生态系统以及生活在其中的生物。此外，在不同国家进行的研究往往没有很好地整合，共享类似数据的数据平台也不发达。这次研讨会将支持一个为期5天的会议，来自美国的研究人员和中国正在研究变化的冰冻圈如何影响山区的水生生态系统。重点将放在潜在的生物相似性(生命规则)如何有助于建立区域之间的联系，以及如何开发数据平台以最大限度地提高对这些变化的科学调查的效率和效力。这次研讨会将有大约20名美国研究人员参加，他们处于不同的职业阶段(从研究生到教授)，以及类似的中国同行。山区正在经历冰冻圈的快速转变，失去了缓冲排放、塑造区域环境和栖息地条件并为人类提供多样化生态系统服务的永久冰雪。冰冻圈正在进行的变化是广泛而复杂的，并影响到高山湖泊和溪流的各种关键参数，如温度、透明度、流量和营养供应。记录、理解和预测这些影响具有挑战性，需要广泛的跨学科协作。在2017年8月在中国青海湖举行的第一次研讨会取得成功的基础上，将在美国举办第二次研讨会有两个目标：1.评估生物群的基本相似性(如新陈代谢的温度依赖性或生物量的化学计量特征)如何有助于理解冰冻圈丧失对水生生态系统的影响；2.为美国/中国联合数据中心建立框架，建立两国多个地点的数据库。这次研讨会将通过美中两国研究人员在两个地区共同紧迫的环境问题上的合作来促进国际合作，为数据共享和合作建立概念框架和先例。协作讲习班的高度跨学科性质还将为包括研究生和博士后在内的所有职业阶段的参与者提供重要的职业发展机会和培训。有关研讨会的更多信息可以在https://renzedyk.wixsite.com/us-china-workshop2This上找到，该奖项反映了国家科学基金会的法定使命，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。

This project supports a workshop in April 2019 at the Flathead Lake Biological Station (Montana) involving researchers from the United States of America and China. The cryosphere is the frozen part of the Earth and involves glacier ice, snowpack, and permafrost. Around the world, cryosphere melt is accelerating, including in mountain regions. These changes are important because mountain regions supply water to 40% of the world's population. However, in many situations it is not well-understood how the changing cryosphere impacts aquatic ecosystems such as lakes and rivers and the organisms that live in them. Furthermore, research conducted in different countries is often not well-integrated and data platforms for sharing of similar data are not well-developed. This workshop will support a 5-day meeting of researchers from the USA and China who are studying how the changing cryosphere affects aquatic ecosystems in mountain regions. An emphasis will be on how underlying biological similarities (Rules of Life) can help draw connections between regions and how data platforms can be developed to maximize efficiency and effectiveness in scientific investigations of these changes. This workshop will involve about 20 USA researchers at a broad range of career stages (graduate students to professors) and a similar cohort of Chinese counterparts. Mountain regions are experiencing rapid transitions in the cryosphere, losing permanent snow and ice that buffer discharge, shape regional environmental and habitat conditions, and provide diverse ecosystem services for humanity. The ongoing changes in the cryosphere are widespread, complex, and affect a variety of key parameters of alpine lakes and streams such as temperature, transparency, discharge, and nutrient supply. Documenting, understanding, and forecasting these impacts is challenging and requires broad interdisciplinary collaborations. Building off of the success of a first workshop held at Qinghai Lake in China in August 2017, a second workshop to be held in the USA has two goals: 1. assessing how fundamental similarities in biota (such as the temperature dependence of metabolism or the stoichiometric signature of biomass) can help understand the impacts of cryosphere loss on aquatic ecosystems and 2. establishing a framework for US/China joint data centers, producing a database across multiple sites in both countries. This workshop will foster international cooperation via collaboration across US and Chinese researchers working on a common, pressing environmental issue in both regions, establishing conceptual frameworks and building precedents for data sharing and collaboration. The highly interdisciplinary nature of the collaboration workshop will also provide important professional development opportunities and training for participants of all career stages including graduate students and postdocs.
