细菌的基本生态位可以沿着沿着许多环境轴来定义，包括温度耐受性和消耗的资源，而与其他生物体的相互作用可以限制（例如竞争）或扩大（例如交叉喂养）实现的生态位。生物体通常被分为通才或专才，对应于广泛或狭窄的生态位要求，然后可以将其与生态系统中的功能作用联系起来。我们将展示这些术语是如何应用于细菌，预测如何由一个有机体显示的类型和程度的通才与其功能潜力，并讨论收集不同类型的通才细菌的价值。我们相信，利用高通量测序和环境操纵的新方法可以让我们了解在培养和尚未培养的细菌中发现的许多类型的普遍性。
The fundamental niches of bacteria can be defined along many environmental axes, including temperature tolerance and resources consumed, while interactions with other organisms can constrain (e.g. competition) or enlarge (e.g. cross-feeding) realized niches. Organisms are often categorized as generalists or specialists, corresponding to broad or narrow niche requirements, which can then be linked to their functional role in an ecosystem. We show how these terms are applied to bacteria, make predictions about how the type and extent of generalism displayed by an organism relates to its functional potential and discuss the value of collecting different types of generalist bacteria. We believe that new approaches that take advantage of both high-throughput sequencing and environmental manipulation can allow us to understand the many types of generalism found within both cultivated and yet-to-be-cultivated bacteria.
