Colourful network: Pair-bonding temporal dynamics involve sexual signals and impact reproduction

Mate choice and pair-bonding are the products of complex decisions involving repeated social interactions over time. They generally rely on multiple sexual signals and behaviours, depend on the phenotype and experiences of the chooser and are affected by environmental conditions and competition for mate access. However, studies investigating the mechanisms of mate selection often ignore the dynamic aspects of the pair formation. In the current study, we used social network analyses to (1) describe sexual interactions over time in multiple groups of captive zebra finches (Taeniopygia guttata), (2) ask how individual sexual signals and body condition relate to pair-bonding temporal dynamics and (3) investigate whether sexual networks influence assortative mating and reproductive performance. We followed sexual interactions of 8 sex-balanced groups of 8 individuals to extract social network metrics over 8 sessions of observation. We assessed individual body condition, sexual signals and co..., , , # Data from: Colourful network: Pair-bonding temporal dynamics involve sexual signals and impact reproduction [https://doi.org/10.5061/dryad.0rxwdbsb5](https://doi.org/10.5061/dryad.0rxwdbsb5) ## Description of the data and file structure The data were collected on 64 adult zebra finches (*Taeniopygia guttata*) in 2022 (between March and October) at the Centre d’Etudes Biologiques de Chizé (CNRS) in France. Data from the file MSBE_Socialinteraction.csv was collected using a group-level scan sampling method to record the sexual behaviour of all individuals within each group (8 groups of 8 individuals in total). We conducted two 20 min observation sessions per group each day, from the release of the birds until pair formations were observed, or after eight sessions of observation (i.e. 4 days). We noted the ID of birds expressing one of the three types of sexual interactions: male song (i.e. singing directed song toward the partner), allopreening (grooming/preening the feather of the...择偶行为与配偶结合是复杂决策的产物，此类决策涉及随时间推进的反复社交互动。这类行为通常依赖多种性信号与行为模式，取决于选择者的表型与既往经历，同时受环境条件与配偶获取竞争的影响。然而，现有探究择偶机制的研究往往忽略了配偶形成过程的动态特征。在本研究中，我们借助社交网络分析（social network analyses）方法，完成三项研究内容：（1）描述多组圈养斑胸草雀（*Taeniopygia guttata*）随时间变化的性互动情况；（2）探究个体性信号与身体状况如何与配偶结合的时间动态特征相关联；（3）调研性社交网络是否会影响选型交配（assortative mating）与繁殖表现。我们对8个性别均衡的组群（每组8只个体）的性互动进行追踪，在8次观测周期内提取社交网络指标。我们对个体身体状况、性信号以及……# 数据源自：《多彩社交网络：配偶结合的时间动态涉及性信号并影响繁殖》 [https://doi.org/10.5061/dryad.0rxwdbsb5] ## 数据与文件结构说明 本数据集采集自2022年（3月至10月）法国国家科学研究中心基兹生物研究中心（CNRS）的64只成年斑胸草雀（*Taeniopygia guttata*）。 文件MSBE_Socialinteraction.csv中的数据采用群体扫描取样法采集，用于记录每组内所有个体的性行为（总计8组，每组8只个体）。我们每日为每组开展两次20分钟的观测周期，观测起始于鸟群释放之时，直至观测到配偶形成，或累计完成8次观测周期（即4天）。我们记录了发生三类性互动之一的个体ID：雄性定向鸣唱（即朝向配偶发出针对性鸣唱）、互相理羽（梳理同伴羽毛……）
