个体变异越来越多地被认为是生态过程的核心组成部分，但其在构建环境生态位协会的作用在很大程度上仍然未知。物种对环境条件的反应最终取决于单个个体的生态位，然而环境关联通常仅在物种水平上被捕获。在这里，我们开发的方案，如何个人的变化可能联合收割机，以定义复合环境生态位的人口，使用广泛的运动数据来记录个人的环境生态位的变化，测试相关的假设生态位配置，并检查随着时间的推移，个人生态位的一致性。对于45个单独的白色鹳（鹳鹳; 116个人年的组合），我们发现高的变异性，在个人的环境协会，一致性的个人生态位随着时间的推移，和中度到强烈的生态位专业化。在种群内部，环境生态位遵循嵌套模式，个体沿着沿着从专家到通才的梯度排列。这些结果拒绝共同的假设，个人生态位之间的同种等价，以及分离的个人生态位到不同的部分环境空间。这些研究结果强调了在全球变化研究中需要更彻底地考虑个人环境反应。了解个体生态位如何变化可以为生态学和保护提供信息。一项研究的45个GPS跟踪白色鹳在三个繁殖种群显示，个人的环境小生境嵌套，安排沿着一个专业通才的梯度，是高度一致的时间。
Individual variation is increasingly recognized as a central component of ecological processes, but its role in structuring environmental niche associations remains largely unknown. Species’ responses to environmental conditions are ultimately determined by the niches of single individuals, yet environmental associations are typically captured only at the level of species. Here, we develop scenarios for how individual variation may combine to define the compound environmental niche of populations, use extensive movement data to document individual environmental niche variation, test associated hypotheses of niche configuration, and examine the consistency of individual niches over time. For 45 individual white storks (Ciconia ciconia; 116 individual-year combinations), we uncover high variability in individual environmental associations, consistency of individual niches over time, and moderate to strong niche specialization. Within populations, environmental niches follow a nested pattern, with individuals arranged along a specialist-to-generalist gradient. These results reject common assumptions of individual niche equivalency among conspecifics, as well as the separation of individual niches into disparate parts of environmental space. These findings underscore the need for a more thorough consideration of individualistic environmental responses in global change research. Understanding how individual niches vary can inform ecology and conservation. A study of 45 GPS-tracked white storks across three breeding populations reveals that individual environmental niches are nested, arranged along a specialist-generalist gradient that is highly consistent over time.
