Impact of UV-B Radiation of Pelagic Freshwater Ecosystems: A Workshop

9316534威廉姆森最近全球平流层臭氧的减少主要是由人为排放的氯氟烃造成的，这导致了紫外线辐射的相应增加，这可能会对自然生态系统造成破坏。虽然最严重的变化发生在极地地区，但人们对淡水生态系统或更高的营养水平如何应对紫外线辐射的变化知之甚少。这次研讨会将提议聚集紫外线-B辐射和淡水生态系统方面的国际专家。研讨会将召集科学家评估紫外线-B辐射如何影响淡水生态系统的已知和需要了解的内容。将制定一份关键研究目标的优先清单，特别关注较高的营养水平。会议将评估目前用于量化水柱中紫外线-B辐射的仪器和生物剂量计技术，为地区大学的学生和教职员工提供专题讲座系列，并鼓励不同学科、国家和地区的合作。会议记录将作为期刊《水生生物档案》的特刊出版。***

9316534 Williamson Recent global decreases in stratospheric ozone induced largely by anthropogenic release of chlorofluorocarbons have led to a corresponding increase in ultraviolet radiation that is potentially damaging to natural ecosystems. While the most serious changes have been in polar regions, little is known about how either freshwater ecosystems or higher trophic levels may respond to changes in ultraviolet radiation. This workshop will proposed to gather international experts in ultraviolet-B radiation and freshwater ecosystems. The workshop will assemble scientists to assess what is known and what needs to be known about how ultraviolet-B radiation influences freshwater ecosystems. A priority list of critical research objectives with a special focus on higher trophic levels will be developed. The meeting will evaluate current instrumentation and biological dosimeter techniques for quantifying ultraviolet-B radiation in the water column, provide a special lecture series to students and faculty from area universities, and encourage collaboration from different disciplines, countries, and regions. The proceedings will be published as a special volume of the journal Archiv fur Hydrobiologia. ***
