Abstract: Colonies of the bacteria Streptomyces coelicolor divide labour between cells that specialize on growth and sporulation and cells that specialize on antibiotic production. This division of labour arises due to costly chromosome deletions in the… read more here.

Abstract: Colonial organisms with division of labour are assumed to achieve increased colony-level efficiency in task performance through functional specialisation of individuals into distinct castes. In social insects, ratios of individuals in different castes can adjust… read more here.

Abstract: This study presents a novel strategy for regulating caste ratio via maternal reproduction in a parthenogenetic social aphid, Pseudoregma bambucicola. Most mothers in the colony produce only soldiers or normal nymphs, whereas a small proportion… read more here.
