Phenotypic variation among individuals and species is a fundamental principle of natural selection. In this review, we focus on numerous experiments involving the model species Daphnia (Crustacea) and categorize the factors, especially secondary ones, affecting intraspecific variations in inducible defense. Primary factors, such as predator type and density, determine the degree to which inducible defense expresses and increases or decreases. Secondary factors, on the other hand, act together with primary factors to inducible defense or without primary factors on inducible defense. The secondary factors increase intraspecies variation in inducible defense, and thus, the level of adaptation of organisms varies within species. Future research will explore the potential for new secondary factors, as well as the relative importance between factors needs to be clarified.

诱导防御种内变异的生态和进化因素：从水蚤实验中获得的见解。

个体和物种之间的表型变异是自然选择的基本原理。在这篇综述中，我们重点关注涉及模型物种水蚤（甲壳纲）的大量实验，并对影响诱导防御种内变异的因素（尤其是次要因素）进行分类。主要因素，例如捕食者类型和密度，决定诱导防御表达和增加或减少的程度。另一方面，次要因素与主要因素一起作用于诱导性防御，或者不与主要因素一起作用于诱导性防御。次要因素增加了诱导防御的种内变异，因此，生物体的适应水平在物种内有所不同。未来的研究将探索新的次要因素的潜力，以及需要澄清的因素之间的相对重要性。
