Ecological drivers and reproductive consequences of non-kin cooperation by ant queens
Results were consistent with the hypothesis that cooperative nesting by unrelated ant queens is likely a selection response to difficult environments, rather than a strategy to maximize reproduction under favorable conditions, and assessment of ecological conditions also support the harsh environment hypothesis.

It is shown that group selection can explain the evolution of cooperative nest founding in the harvester ant Pogonomyrmex californicus, and it is found that aggressive individuals had a survival advantage within their nest, but foundress groups with such non-cooperators died out more often than those with only cooperative members.

Ecological Drivers of Non-kin Cooperation in the Hymenoptera
The diversity and organization of non-kin sociality across the Hymenoptera is reviewed, particularly among the communal bees and polygynous ants and wasps, with a particular focus on ecological factors.
