摘要

Behavioral traits can differ between individuals in a population and affect their fitness if they differentially influence survivorship in a microhabitat scale. This may occur when individuals experience different predation risks between microhabitats. In this study, we investigated boldness, exploration, and their correlation depending on the microhabitat of origin in the hermit crab Clibanarius symmetricus. Individuals of both sexes were collected from four microhabitats with different levels of predation exposure within the intertidal zone of a mangrove. We conducted experiments introducing the hermit crabs to a new standard environment and simulated predation attempts to assess exploration and boldness. Latency to re-emerge from the shell (boldness) was consistent and not affected by size, sex, or microhabitat type, but was slightly different between years. Exploration, in turn, varied only according to the microhabitat from which individuals were collected. Hermit crabs from the less risky environments explored the experimental arena for longer than individuals from the microhabitat most exposed to predators. This behavioral consistency in exploration activity can influence microhabitat choice in C. symmetricus. In addition, boldness and exploration were weakly correlated in a behavioral syndrome. Therefore, predation exposure can be a source of variation in exploration-avoidance personalities and can indirectly influence the expression of boldness in C. symmetricus. We conclude that personality traits can coevolve and have implications for habitat choice, but traditional theories of individual behavioral consistency still lack a unified theoretical background linking animal personality to niche specialization with empirical support.

Symmetricus的微藻选择。此外，在行为综合征中粗体和探索弱。因此，捕食曝光可以是勘探 - 避免性质的变异源，并且可以间接地影响C.对称性的粗体表达。我们得出结论，人格特质可以共同发展，对栖息地选择产生影响，但是个人行为一致性的传统理论仍然缺乏将动物个性与实证支持专业化的统一理论背景联系起来。
