项目摘要
Many protozoa have been shown to play a major role in regulating metabolism in bacteria, which is central to nutrient cycling in virtually all ecosystems on Earth. All organisms depend on these cycling processes, and thus protozoa are integral to the continual existence of life on earth. Understanding which species of protozoa play which role in nutrient cycling will result in more accurate environmental models, a greater ability to manipulate microbial communities in bioreactors, an improved understanding of ecosystem engineering, and aid projects aimed at increasing agricultural productivity. Because the ecology of microbial communities is usually highly complex, this project will use soils from the relatively simple ecosystems of the McMurdo Dry Valleys (MDV) in Antarctica to explore the relationship between protozoan communities and nutrient cycling. Dr. Craig Cary at the University of Waikato in Hamilton, New Zealand is accomplished at characterizing microbial communities in Antarctic environments and has access to unique microcosms that will be essential for this project. Antarctic soil will be incubated in artificial soil microcosms for an extended period of time to capture the dynamics of a community in nature. Changes in protozoan and bacterial community structure will be subsampled and sequenced at prescribed intervals. Soil geochemistry and nutrient concentration will be analyzed to link nutrient availability to community composition. To provide context for the incubation experiment, environmental DNA from diverse locations and a range of soil chemistries will also be target-sequenced. Significance of bacterial and protozoan species correlation will be inferred using multidimensional scaling (MDS). These data will elucidate habitat suitability models for MDV protozoa, clarifying which elements of the community are driven by abiotic or biotic constraints, respectively. This NSF EAPSI award is funded in collaboration with Royal Society of New Zealand.
许多原生动物已被证明在调节细菌代谢方面发挥着重要作用,而细菌代谢是地球上几乎所有生态系统中营养循环的核心。所有生物都依赖于这些循环过程,因此原生动物是地球上生命持续存在的组成部分。了解哪种原生动物在营养循环中扮演何种角色将导致更准确的环境模型,更大的能力来操纵生物反应器中的微生物群落,更好地理解生态系统工程,以及旨在提高农业生产力的援助项目。由于微生物群落的生态学通常是高度复杂的,本项目将使用南极洲麦克默多干谷(MDV)相对简单的生态系统的土壤来探索原生动物群落与养分循环之间的关系。新西兰汉密尔顿的怀卡托大学的克雷格卡里博士擅长描述南极环境中的微生物群落,并能接触到对本项目至关重要的独特的微观世界。 南极土壤将在人造土壤微观世界中培养一段时间,以捕捉自然界中一个群落的动态。原生动物和细菌群落结构的变化将在规定的时间间隔内进行二次取样和测序。将分析土壤地球化学和养分浓度,将养分的可用性与群落组成联系起来。为了提供孵化实验的背景,还将对来自不同地点和一系列土壤化学物质的环境DNA进行靶向测序。将使用多维标度(MDS)推断细菌和原生动物物种相关性的意义。这些数据将阐明MDV原生动物的栖息地适宜性模型,澄清社区的哪些元素是由非生物或生物的限制,分别驱动。这个NSF EAPSI奖是与新西兰皇家学会合作资助的。
