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于人为释放氟氯化碳造成的，这导致紫外线辐射相应增加，可能对自然生态系统造成损害。 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。 该讲习班将提议召集紫外线-B辐射和淡水生态系统方面的国际专家。 讲习班将召集科学家，评估关于紫外线B辐射如何影响淡水生态系统的已知和需要知道的情况。 将制定一份重点研究目标优先清单，特别侧重于高营养级。 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，为来自地区大学的学生和教师提供特别系列讲座，并鼓励不同学科，国家和地区的合作。 会议记录将作为《水生生物学档案》杂志的特刊出版。***

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. ***
