进化生态学家经常试图找出维持种内变异的机制。在社会性动物中,整个群体可以在集体特征上表现出群体间的差异。我们研究了负频率依赖选择(即稀有型优势)是否有助于维持组间变异。我们设计的社区社会蜘蛛殖民地轴承大胆或害羞的觅食表型,并监测其繁殖力在原位。我们发现,大胆的殖民地享有稀有型的优势,是失去了大胆的殖民地在附近的频率增加。害羞的殖民地的成功是不依赖于频率。这些动态似乎是由一个大胆的殖民地,失去了大胆的社区,因为猎物变得稀缺,害羞的殖民地表现得更好,在低资源条件下大胆的殖民地觅食优势。因此,要理解集体特征的选择,孤立地研究群体是不够的。群体居住和竞争的表型环境也必须考虑。
Evolutionary ecologists often seek to identify the mechanisms maintaining intraspecific variation. In social animals, whole groups can exhibit between-group differences in their collective traits. We examined whether negative frequency-dependent selection (that is, a rare-type advantage) could help to maintain between-group variation. We engineered neighbourhoods of social spider colonies bearing bold or shy foraging phenotypes and monitored their fecundity in situ. We found that bold colonies enjoyed a rare-type advantage that is lost as the frequency of bold colonies in a neighbourhood increases. The success of shy colonies was not frequency dependent. These dynamics seem to be driven by a foraging advantage of bold colonies that is lost in bold neighbourhoods because prey become scarce, and shy colonies perform better than bold colonies under low-resource conditions. Thus, to understand selection on collective traits, it is insufficient to examine groups in isolation. The phenotypic environment in which groups reside and compete must also be considered.
