社会接触可以促进生存相关信息和传染病的传播，但人们对这些过程如何联合收割机塑造宿主和寄生虫的进化知之甚少。在这里，我们使用一个理论模型，捕捉感染和信息传递过程，以研究宿主社会性（接触努力）和寄生虫毒力（疾病相关死亡率）（共同）如何演变。我们发现，社会性（反过来，毒力）的选择取决于社会信息和感染的内在成本和收益，以及它们在人群中的相对流行率。具体来说，当感染风险低或高并且社会信息既不太常见也不太罕见时，就会出现更大的社会性和更低的毒力。当流行模式逆转时，社会性降低，毒性增加。当感染和社会信息在人群中都处于中等水平时，选择的方向取决于被感染或被告知的相对成本和收益。我们还表明，社会性与毒力成反比，寄生虫可能无法防止失控的选择更高的接触努力。总之，这些发现为我们理解群体生活以及明显对立的生态过程如何以各种方式影响社会性和毒性的进化提供了新的见解。
Social contacts can facilitate the spread of both survival‐related information and infectious diseases, but little is known about how these processes combine to shape host and parasite evolution. Here, we use a theoretical model that captures both infection and information transmission processes to investigate how host sociality (contact effort) and parasite virulence (disease‐associated mortality rate) (co)evolve. We show that selection for sociality (and in turn, virulence) depends on both the intrinsic costs and benefits of social information and infection as well as their relative prevalence in the population. Specifically, greater sociality and lower virulence evolve when the risk of infection is either low or high and social information is neither very common nor too rare. Lower sociality and higher virulence evolve when the prevalence patterns are reversed. When infection and social information are both at moderate levels in the population, the direction of selection depends on the relative costs and benefits of being infected or informed. We also show that sociality varies inversely with virulence, and that parasites may be unable to prevent runaway selection for higher contact efforts. Together, these findings provide new insights for our understanding of group living and how apparently opposing ecological processes can influence the evolution of sociality and virulence in a range of ways.
