Journal Article
Berghoff, S. M., Wurst, E., Ebermann, E., Sendova-Franks, A. B., Rettenmeyer, C. W., & Franks, N. R. (2009). Symbionts of societies that fission: Mites as guests or parasites of army ants. Ecological Entomology, 34(6), 684-695. https://doi.org/10.1111/j.1365-2311.2009.01125.x

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.

Division of labour in ant colonies in terms of attractive fields (2009)

In nature there exist many mechanisms giving rise to self-regulation. One such mechanism is the division of labour in insect societies. Within this work we propose a mathematical model for the allocation of tasks in ant colonies, where each of the ta...
