Detecting and quantifying our biodiversity is a fundamental prerequisite to understanding how our ecosystems and their services are formed, and how natural and anthropogenic factors effect ecosystem viability. Whilst this is well advanced for most fields of animal and plant ecology, the microscopic nature of bacteria means we have virtually no understanding of what the major groups of bacteria, or their distributions, are within Great Britain. Critically, bacteria perform central roles in enhancing plant productivity and biogeochemical nutrient cycling. It is imperative that we understand which major groups are present, what controls their distribution, and how environmental changes occurring now, and in the future, will affect the diversity of their populations, the biogeochemical functions they perform and how this maps to integrated ecosystem assessments. In this application, we propose to address this shortfall by assessing the occurrence of major terrestrial bacterial groups across the whole of England, Scotland and Wales, as part of the upcoming Countryside Survey of 2007. In this globally unique approach, we will detect bacterial groups by high throughput molecular biological methods, measure key soil chemistry parameters, and co-analyse these data rich variables to address several key hypotheses. Further, we will produce high resolution maps of bacterial group distribution across Great Britain and couple these data to existing publicly available data, disseminated through the world wide web, within the Countryside Survey 2007 core programme. Finally, during the process of this investigation, we will form and archive a nationally accessible genome bank for use by other investigators in order that they may address their own specific hypotheses in relation to other microbial groups and processes.

检测和量化我们的生物多样性是了解我们的生态系统及其服务如何形成以及自然和人为因素如何影响生态系统活力的基本先决条件。虽然这对于动植物生态学的大多数领域来说都是非常先进的，但细菌的微观性质意味着我们实际上不了解英国境内的主要细菌类群或其分布。至关重要的是，细菌在提高植物生产力和生物地球化学养分循环方面发挥着核心作用。我们必须了解存在哪些主要群体，是什么控制着它们的分布，以及现在和未来发生的环境变化将如何影响其种群的多样性、它们所执行的生物地球化学功能以及如何将其映射到综合生态系统评估。在本申请中，我们建议通过评估整个英格兰、苏格兰和威尔士主要陆地细菌群的出现情况来解决这一不足，作为即将进行的 2007 年乡村调查的一部分。在这种全球独特的方法中，我们将通过高通量分子生物学方法检测细菌群，测量关键土壤化学参数，并共同分析这些数据丰富的变量，以解决几个关键假设。此外，我们将制作英国各地细菌群分布的高分辨率地图，并将这些数据与 2007 年乡村调查核心计划中通过万维网传播的现有公开数据结合起来。最后，在这项调查过程中，我们将建立并存档一个全国范围内可访问的基因组库，供其他研究人员使用，以便他们可以解决与其他微生物群体和过程相关的特定假设。
