Blinkered teaching: Tandem running by visually impaired ants (2011)
Journal Article

Recently, Hughes et al. (Trends in Ecology & Evolution, 23, 672-677, 2008) have theorised that symbionts of large, long-lived, homeostatic, and well defended social insect colonies should mostly be of low virulence. If the symbionts are rare, i.e. fe... Read More about Symbionts of societies that fission: Mites as guests or parasites of army ants.
