1. 个体之间的直接互动在群居动物的社会性、交配系统和疾病传播中起着重要作用。在这里，我们设计了一种方法，从无线电跟踪数据中量化近距离相互作用的相对比率，并突出了英格兰东北部中等密度獾种群接触网络中潜在的不对称性。我们分析了从四个连续的社会群体收集的无线电跟踪数据，收集时间超过3年。动态相互作用分析是用来评估个体的运动与其他运动的关系，在社会群体内部和之间。对所涉及的獾的季节、性别、年龄和设置使用模式进行了评估。组内分离距离明显短于组间分离距离，组间相互作用较少。在群体中，个体之间的互动比预期的要频繁，而且互动模式随着季节和使用模式的不同而显著变化。非移动组（在50%的情况下使用主组进行日间休息）比移动组（在50%的情况下使用离群组进行日间休息）或移动-非移动组的互动频率更高。在冬季，群体成员之间的互动最为频繁。在密切的群体内相互作用（< 50 m的分离距离）中，88.6%与主要集相关，只有4.4%与异常集相关。在主集合中，非移动二元组和非移动二元组的相互作用明显多于只移动二元组。这些结果强调了主要群体对獾社会性的重要性，并支持了獾社会群体由不同的子群体组成的观点，在我们的案例中，这是基于不同的群体使用模式。人群中接触结构的不对称将影响疾病通过社会网络传播的方式。对这些网络进行评估对于了解疾病在不能自由混合或在空间或社会行为上表现出异质性的人群中的持续存在和传播至关重要。
1. Direct interactions between individuals play an important part in the sociality of group-living animals, their mating system and disease transmission. Here, we devise a methodology to quantify relative rates of proximity interaction from radio-tracking data and highlight potential asymmetries within the contact network of a moderate-density badger population in the north-east of England.2. We analysed radio-tracking data from four contiguous social groups, collected over a 3-year period. Dynamic interaction analysis of badger dyads was used to assess the movement of individuals in relation to the movement of others, both within and between social groups. Dyads were assessed with regard to season, sex, age and sett use pattern of the badgers involved.3. Intragroup separation distances were significantly shorter than intergroup separation distances, and interactions between groups were rare. Within groups, individuals interacted with each other more often than expected, and interaction patterns varied significantly with season and sett use pattern. Non-mover dyads (using the main sett for day-resting on > 50% of occasions) interacted more frequently than mover dyads (using an outlier sett for day-resting on > 50% of occasions) or mover-non-mover dyads. Interactions between group members occurred most frequently in winter.4. Of close intragroup interactions (< 50 m separation distance), 88.6% were associated with a main sett and only 4.4% with outlier setts. Non-mover dyads and non-mover-mover dyads interacted significantly more often at the main sett than mover-only dyads. These results highlight the importance of the main sett to badger sociality and support the suggestion that badger social groups are comprised of different subgroups, in our case based on differential sett use patterns.5.Asymmetries in contact structure within a population will affect the way in which diseases are transmitted through a social network. Assessment of these networks is essential for understanding the persistence and spread of disease within populations which do not mix freely or which exhibit heterogeneities in their spatial or social behaviour.
