Infochemicals, including hormones, pheromones, and allelochemicals, play a central role in mediating information and shaping interactions within and between individuals. Due to their high plasticity, infochemicals are predestined mediators in facilitating individualized niches of organisms. Only recently it has become clear that individual differences are essential to understand how and why individuals realize a tiny subset of the species' niche. Moreover, individual differences have a central role in both ecological adjustment and evolutionary adaptation in a rapidly changing world. Here we highlight that infochemicals act as key signals or cues and empower the realization of the individualized niche through three proposed processes: niche choice, niche conformance, and niche construction.

信息化学物质，包括激素，信息素和化感物质，在调节信息以及塑造个体内部和个体之间的相互作用方面起着核心作用。由于信息化学物质具有很高的可塑性，因此它们是促进有机体个性化生态位的预定媒介。直到最近才变得清楚，个体差异对于理解个体如何以及为什么意识到物种利基的一小部分至关重要。此外，在迅速变化的世界中，个体差异在生态调节和进化适应中都起着核心作用。在这里，我们重点介绍信息化学物质作为关键信号或线索，并通过三个拟议的过程来实现个性化利基的实现：利基选择，利基一致性和利基构建。
