BIOCOMPLEXITY-INCUBATION ACTIVITY: The Effects of Global Change On Community Structure, Biodiversity And Ecosystem-Level Processes In Pinyon-Juniper Woodlands

[00:83623 .格林]全球变化正在影响世界各地的生态系统，其中一些影响最强烈的是美国西南部的干旱地区。为了应对最近的干旱，树木大量死亡，有害昆虫也达到了创纪录的水平。这些变化对植物、动物和微生物的影响可能会改变整个生态系统的功能，从而影响生活在干旱地区的人口。我们在生态学、遗传学、生理学和土壤科学方面组建了一个研究小组，他们研究了帮助植物从土壤中获取营养的土壤微生物，攻击干旱胁迫树木的昆虫，以及在美国西南部最大的森林类型之一中鸟类和哺乳动物的重要性。我们建议举行一次研讨会和虚拟会议，以便这些专家可以发展新的合作并确定未来的研究领域，这些领域将最好地应对干旱环境中全球变化的挑战。本次研讨会的目标是通过结合其他学科和技术，如计算机建模和稳定同位素分析，扩大我们对复杂生态过程的理解，以预测全球变化对生态和遗传系统的可能影响。

0083623GehringGlobal changes are affecting ecosystems worldwide, and some of the strongest effects are in the arid lands of the southwestern US. In response to recent droughts, trees have died in large numbers and harmful insects have expanded to record levels. How these changes impact plants, animals and microbes may change the way entire ecosystems function, thereby affecting human populations living in arid areas. We have assembled a team of researchers in ecology, genetics, physiology and soil science who have studied the soil microbes that help plants acquire nutrients from the soil, the insects that attack drought-stressed trees, and the importance of birds and mammals in one of the largest forest types of the southwestern US. We propose to hold a workshop and virtual meetings so that these experts may develop new collaborations and determine areas of future research that will best meet the challenges of global change in arid environments. The goals of this workshop are to expand our understanding of complex ecological processes by incorporating other disciplines and technologies, like computer modeling and stable isotope analysis, to predict the likely impacts of global change on ecological and genetic systems.
