植物根据生态条件做出觅食决策，例如资源的可用性和分布。尽管植物行为生态学领域发展势头强劲，但生态学家仍然对影响植物行为的因素知之甚少，尤其是光觅食行为。我们利用行为反应规范方法来研究一种表现出快速运动的植物物种的光觅食：含羞草。我们探索了M. pudica（受到干扰时会暂时关闭小叶）的食草动物回避行为如何受到个体能量状态和当前环境质量的影响，并且还反复测试了来自两个种子来源的个体的行为，以确定个体是否表现出“个性”（即行为综合症）。我们发现，当个体处于低能量状态时，它们会采取风险较高的光觅食策略，更快地打开传单，并且不会经常关闭传单以应对干扰。然而，当植物处于高能量状态时，它们会表现出依赖于环境质量的塑料光觅食策略。尽管我们没有发现任何证据表明个体表现出行为综合症，但我们发现来自不同种子来源的个体始终表现出不同的行为。我们的结果表明，植物能够做出依赖于状态的决策，并且植物决策是复杂的，取决于内部和外部因素之间的相互作用。
Plants make foraging decisions that are dependent on ecological conditions, such as resource availability and distribution. Despite the field of plant behavioral ecology gaining momentum, ecologists still know little about what factors impact plant behavior, especially light‐foraging behavior. We made use of the behavioral reaction norm approach to investigate light foraging in a plant species that exhibits rapid movement: Mimosa pudica. We explored how herbivore avoidance behavior in M. pudica (which closes its leaflets temporarily when disturbed) is affected by an individual's energy state and the quality of the current environment and also repeatedly tested the behavior of individuals from two seed sources to determine whether individuals exhibit a “personality” (i.e., behavioral syndrome). We found that when individuals are in a low‐energy state, they adopt a riskier light‐foraging strategy, opening leaflets faster, and not closing leaflets as often in response to a disturbance. However, when plants are in a high‐energy state, they exhibit a plastic light‐foraging strategy dependent on environment quality. Although we found no evidence that individuals exhibit behavioral syndromes, we found that individuals from different seed sources consistently behave differently from each other. Our results suggest that plants are capable of making state‐dependent decisions and that plant decision making is complex, depending on the interplay between internal and external factors.
