The specific aim of our study was to test individual common shrews from a population monitored long-term. In a preference test, we revealed sex-related differences in behavioral traits of young common shrews and consistent individual differences in sociability, boldness and in an exploration pattern that have not been reported previously. More active animals were bolder and more superficial in the exploration of non-social objects as compared to shier shrews. Significant inter-annual differences in sociability, boldness and exploratory activity were observed. When we assessed correlations of sociability with population density, non-residents’ abundance, activity shared in space, survivorship and home range size, we found a positive association with shared spatial activity and home range size. Contrary to expectation, sociability did not correlate with the density of residents and survivorship. A significant negative association of sociability with non-residents’ abundance was documented. Survivorship was associated only with an exploration pattern. The thoroughness of exploration positively correlated with non-residents’ abundance. We regard the inter-annual changes in sociability that we observed in the test as a by-product of survival of shrews with various exploration patterns that are associated with dispersal. We can hypothesize that the personality differences registered in this study are maintained by balancing frequency-dependent selection of animals that is associated with differences in habitat quality throughout the population cycle.

我们研究的具体目的是测试长期监测的人群中的个体普通鼩鼱。在一项偏好测试中，我们揭示了年轻的普通鼩鼱行为特征的性别相关差异，以及在社交能力、胆识和探索模式方面的一致个体差异，这是以前未曾报道过的。与喜怒无常的鼩鼱相比，更活跃的动物在探索非社交对象时更大胆、更肤浅。观察到社交能力、胆识和探索活动的显着年际差异。当我们评估社交性与人口密度、非居民的丰度、空间共享活动、生存率和家庭范围大小的相关性时，我们发现共享空间活动和家庭范围大小呈正相关。出乎意料，社交能力与居民密度和生存率无关。记录了社交性与非居民丰富度的显着负相关。生存仅与探索模式有关。勘探的彻底性与非居民的丰度呈正相关。我们将我们在测试中观察到的社交能力的年际变化视为鼩鼱生存的副产品，这些鼩鼱具有与分散相关的各种探索模式。我们可以假设，通过平衡与整个种群周期中栖息地质量差异相关的与频率相关的动物选择，可以维持本研究中记录的个性差异。记录了社交性与非居民丰富度的显着负相关。生存仅与探索模式有关。勘探的彻底性与非居民的丰度呈正相关。我们将我们在测试中观察到的社交能力的年际变化视为鼩鼱生存的副产品，这些鼩鼱具有与分散相关的各种探索模式。我们可以假设，通过平衡与整个种群周期中栖息地质量差异相关的与频率相关的动物选择，可以维持本研究中记录的个性差异。记录了社交性与非居民丰富度的显着负相关。生存仅与探索模式有关。勘探的彻底性与非居民的丰度呈正相关。我们将我们在测试中观察到的社交能力的年际变化视为鼩鼱生存的副产品，这些鼩鼱具有与分散相关的各种探索模式。我们可以假设，通过平衡与整个种群周期中栖息地质量差异相关的与频率相关的动物选择，可以维持本研究中记录的个性差异。我们将我们在测试中观察到的社交能力的年际变化视为鼩鼱生存的副产品，这些鼩鼱具有与分散相关的各种探索模式。我们可以假设，通过平衡与整个种群周期中栖息地质量差异相关的与频率相关的动物选择，可以维持本研究中记录的个性差异。我们将我们在测试中观察到的社交能力的年际变化视为鼩鼱生存的副产品，这些鼩鼱具有与分散相关的各种探索模式。我们可以假设，通过平衡与整个种群周期中栖息地质量差异相关的与频率相关的动物选择，可以维持本研究中记录的个性差异。
