dc.description.abstract | Cooperation among non-kin constitutes a conundrum for evolutionary biology. Theory suggests that
non-kin cooperation can evolve if individuals differ consistently in their cooperative phenotypes and
assort socially by these, such that cooperative individuals interact predominantly with one another.
However, our knowledge of the role of cooperative phenotypes in the social structuring of real-world
animal populations is minimal. In this study, we investigated cooperative phenotypes and their link to
social structure in wild Trinidadian guppies (Poecilia reticulata). We first investigated whether wild
guppies are repeatable in their individual levels of cooperativeness (i.e. have cooperative phenotypes)
and found evidence for this in seven out of eight populations, a result which was mostly driven by
females. We then examined the social network structure of one of these populations where the expected
fitness impact of cooperative contexts is relatively high, and found assortment by cooperativeness, but
not genetic relatedness. In contrast, in accordance with our expectations we did not find assortment by
cooperativeness in a population where the expected fitness impact of cooperative contexts is lower. Our
results provide empirical support for current theory and suggest that assortment by cooperativeness is
important for the evolution and persistence of non-kin cooperation in real-world populations. | en_GB |
