Precipitation Pulse Effects in Arid and Semi-arid Ecosystems -- Workshop (Tucson, Arizona)

最近观察到，缺水生态系统中的大部分降水来自大型的零星风暴事件，这些脉冲事件而不是年平均降水量可能是表征降水的更重要的方式。该讲习班将在多个生物尺度上审查干旱和半干旱环境中的降水脉冲事件的影响。在这些生态系统中，降雨事件的时间、持续时间和强度自然是不同的，被认为控制着其居民的生活史战略、种群动态、群落变化、对入侵的恢复能力、土壤养分动态和生态系统养分通量。由于全球变暖，预计全世界干旱和半干旱生态系统的降水模式将发生变化。该讲习班的目的是召集一批不同的国际研究人员，以促进区域间和学科间的交流、数据综合、理论发展和培训。研讨会将为一本广为阅读的生态杂志撰写一篇评论文章，并为研究人员、教育工作者和专业人员提供网站资源。

It has recently been observed that the majority of precipitation in water-limited ecosystems comes in large, sporadic storm events and that these pulse events, rather than annual mean precipitation, may be the more significant manner by which to characterize precipitation. This workshop will examine the effects of pulse events in precipitation in arid and semi-arid environments at multiple biological scales. The timing, length and intensity of rainfall events is naturally variable in these ecosystems and is thought to govern the life history strategies of its inhabitants, population dynamics, community change, resilience to invasion, soil nutrient dynamics and ecosystem nutrient fluxes. As a consequence of global warming, precipitation patterns are expected to change in arid and semi-arid ecosystems worldwide. The purpose of this workshop is to convene a diverse group of international researchers in order to facilitate interregional and interdisciplinary exchange, data synthesis, theory development and training. The workshop will produce a review article targeted for a broadly read ecological journal along with website resources for researchers, educators and professionals.
