Experimental manipulation of queen number affects colony sex ratio investment in the highly polygynous ant Formica exsecta.

Proceedings. Biological sciences - 7 Sept 2005

Kümmerli Rolf, Helms Ken R, Keller Laurent

Abstract excerpt

In polygynous (multiple queens per nest) ants, queen dispersal is often limited with young queens being recruited within the parental colony. This mode of dispersal leads to local resource competition between nestmate queens and is frequently associated with extremely male-biased sex ratios at the population level. The queen-replenishment hypothesis has been recently proposed to explain colony sex ratio...
