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

最近观察到，在水有限的生态系统中，大部分降水来自大的，零星的风暴事件，这些脉冲事件，而不是年平均降水量，可能是更重要的方式来表征降水。该研讨会将在多个生物尺度上研究干旱和半干旱环境中降水脉冲事件的影响。在这些生态系统中，降雨事件的时间、长度和强度是自然可变的，被认为支配着其居民的生活史策略、人口动态、群落变化、对入侵的恢复力、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。研讨会将为一份广泛阅读的生态学杂志撰写一篇评论文章沿着为研究人员、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.
