水蚤通过改变其形态、行为和生活史来对来自各种捕食者（Chaoborus、Notonecta、鱼类）的利它素做出反应。在这些捕食者存在的情况下引起的生活史变化的适应性尚未明确，这些变化要么被视为形态防御的成本，要么被视为反捕食者适应本身。我使用荟萃分析的统计技术结合了两打以上研究的结果，这些研究检查水蚤的生活史变化以应对不同的捕食者。这项分析得出了关于这些生活史反应、它们之间的关系以及它们在反捕食者防御进化中的作用的一般结论。
Daphnia react to kairomones from a variety of predators (Chaoborus, Notonecta, fish) by altering their morphology, behavior, and life history. The adaptive nature of induced life history shifts in the presence of these predators has not been established clearly, with these changes being alternatively viewed as either the cost of morphological defenses or as anti-predator adaptations themselves. I use the statistical techniques of meta-analysis to combine the results of more than two dozen studies that examine life history shifts in Daphnia in response to different predators. This analysis produces general conclusions on these life history responses, their relationships to each other, and their role in the evolution of antipredator defenses.
