在生态学中，生态位是一个物种与特定环境条件的匹配。它描述了生态位的3种变体如何对资源和竞争对手的分布做出反应(例如，在资源丰富的时候生长，而在捕食者、寄生虫和病原体稀缺的时候生长) ，以及它如何反过来改变这些相同的因素(例如，限制其他生物对资源的获取，充当捕食者的食物来源和猎物的消费者)。”构成环境生态位尺度的变量的类型和数量因物种而异，[而]特定环境变量对某一物种的相对重要性可能因地理和生物环境而异”。另见第二章: 壁龛的概念，第页。7 ff

A Grinnellian niche is determined by the [[habitat]] in which a species lives and its accompanying [[Behavioral ecology|behavioral adaptations]]. An Eltonian niche emphasizes that a species not only grows in and responds to an environment, it may also change the environment and its behavior as it grows. The Hutchinsonian niche uses mathematics and statistics to try to explain how species coexist within a given community.
