Abstract 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.

永远不要忘记你来自哪里:起源的微型栖息地影响寄居蟹 Clibanaruus symmetricus(Diogenidae)的大胆和探索
摘要 行为特征在种群中的个体之间可能不同,如果它们在微生境尺度上对生存有不同的影响,则会影响他们的健康。当个体在微生境之间经历不同的捕食风险时,可能会发生这种情况。在这项研究中,我们根据寄居蟹 Clibanarius symmetricus 的起源微生境调查了大胆、探索及其相关性。从红树林潮间带内具有不同捕食暴露水平的四个微生境中收集了两种性别的个体。我们进行了实验,将寄居蟹引入新的标准环境,并模拟捕食尝试以评估探索和胆量。从壳中重新出现的潜伏期(粗体)是一致的,不受大小、性别或微生境类型的影响,但年份之间略有不同。反过来,探索仅根据收集个体的微生境而有所不同。与来自最暴露于捕食者的微栖息地的个体相比,来自风险较低环境的寄居蟹探索实验场所的时间更长。探索活动中的这种行为一致性会影响 C. symmetricus 中的微生境选择。此外,大胆和探索在行为综合征中的相关性很弱。因此,捕食暴露可能是探索回避型人格变异的一个来源,并且可以间接影响 C. symmetricus 中大胆的表达。我们得出结论,个性特征可以共同进化并对栖息地选择产生影响,
