Effect of pleometrosis and brood transplantation on colony growth of the black garden ant, Lasius niger

Natalia E. L. Madsen & Joachim Offenberg
In response to intra- and interspecific competition, ant colonies have evolved mechanisms to maximize early colony growth. Through the analysis of photographic images, this study describes the individual effect of two different strategies, pleometrosis and pupae transplantation, on the growth of Lasius niger colonies. Results showed that both methods had an overall positive effect on colony production, albeit the magnitude at which pupae transplantation boosted colony growth was much larger than pleometrosis. After six weeks,...
