Data for: What you have, not who you know: food-enhanced social capital and changes in social behavioural relationships in a non-human primate

Social network position in non-human primates has far-reaching fitness consequences. Critically, social networks are both heterogenous and dynamic, meaning an individual’s current network position is likely to change due to both intrinsic and extrinsic factors. However, our understanding of the drivers of changes in social network position is largely confined to opportunistic studies. Experimental research on the consequences of in situ, controlled network perturbations is limited. Here we conducted a food-based experiment in rhesus macaques to assess whether allowing an individual the ability to provide high-quality food to her group changed her social behavioural relationships. We considered both her social network position across five behavioural networks, as well as her dominance and kin interactions. We found that gaining control over a preferential food resource had far-reaching social consequences. There was an increase in both submission and aggression centrality and changes in ..., Data collection:
Data were collected on a single group of Rhesus macaques. Behavioural observations were conducted all adult individuals (3+ years) in the group. Affiliative and agonistic interactions were recorded.
Data processing:
Behavioural observations were used to construct a weighted, directed behavioural network for each of the following behaviours, for both baseline and experimental phases separately: (1) dyadic aggressive interactions where aggressive behaviour was met with a clear submissive response, (2) approach – move away interactions, such as displacements, (3) SBT signals in response to peaceful approaches (note: peaceful SBTs may be accompanied by other submissive behaviours including turn away, move away. or rump present), and (4) social grooming interactions. Weighted, undirected networks were constructed for huddling/social contact and proximity interactions. For directed behaviours, indegree, outdegree (the number of adjacent edges to each node), and strength (tota..., , # Dataset for \"What you have, not who you know: food-enhanced social capital and changes in social behavioural relationships in a non-human primate\"

The goal of the experiment was to assess whether allowing an individual Rhesus macaque to provide food to her group changed her social behavioural relationships. Our study consisted of a 4-week baseline period and a 4-week experimental period during which behavioural observations were conducted. During the baseline period, there were no changes to daily routine. During the experimental period, one female with average dominance rank and average social connectivity was trained to open a food box and provide high-quality food to her group once per day. The provider monkey was trained using standard positive reinforcement techniques to pull a non-functional lever on a feeder box when cued by research staff.

Behavioural observations were conducted by two observers four days per week on all adult individuals (3+ years) in the group. One obser...

非人灵长类的社会网络（social network）位置对其适合度（fitness）具有深远影响。至关重要的是，社会网络兼具异质性与动态性，即个体当前的网络位置可能因内在和外在因素发生改变。然而，目前我们对社会网络位置变化驱动因素的认知，大多局限于偶发性观测研究。针对原位（in situ）可控网络扰动效应的实验研究仍较为匮乏。

本研究以恒河猴（Rhesus macaques）为对象开展了基于食物供给的实验，旨在探究赋予个体向群体提供优质食物的能力后，其社会行为关系是否会发生改变。我们同时分析了该个体在五种行为网络中的社会网络位置，以及其支配与亲属互动模式。研究发现，获得优先食物资源的控制权会产生广泛的社会效应：服从与攻击中心性均有所提升，且发生了……

## 数据收集：
本研究的数据源自一个恒河猴群体。研究人员对群体内所有成年个体（3岁及以上）开展行为观测，并记录其亲和（affiliative）与攻击（agonistic）互动行为。

## 数据处理：
研究人员基于行为观测数据，分别为基线期与实验期构建了针对以下四类行为的加权有向行为网络：（1）攻击行为伴随明确服从回应的二元攻击互动；（2）趋近-逃离互动，如驱赶行为；（3）平静趋近触发的SBT信号（注：平静状态下的SBT信号可能伴随其他服从行为，包括转身、远离或露出臀部）；（4）社会梳毛互动。同时，针对依偎/社会接触与近距离互动构建了加权无向网络。对于有向行为，我们计算了入度（indegree）、出度（outdegree，即每个节点的邻边数量）以及强度（总……）[原文截断]。

本实验旨在探究赋予单只恒河猴向群体提供食物的能力后，其社会行为关系是否会发生改变。本研究分为为期4周的基线期与实验期，两个阶段均开展行为观测。基线期内，猴群日常作息无任何变动。实验期内，研究人员训练一只具有平均支配等级与平均社会连接度的雌性恒河猴，使其能够每日一次打开食盒并为群体提供优质食物。该供食猴通过标准正向强化训练法，在研究人员提示下拉动食盒上的非功能性拉杆。

行为观测由两名观察员每周开展四天，覆盖群体内所有成年个体（3岁及以上）。一名观测……[原文截断]
