  1. Smith A, Hölldobler B, Liebig J. Hydrocarbon signals explain the pattern of worker and egg policing in the ant Aphaenogaster cockerelli. J Chem Ecol. 2008;34:1275-82 pubmed publisher
    ..This queen-like signaling may be due to workers maintaining a high level of ovarian activity, linked to trophic egg production, in the presence of the queen. ..
  2. Dolezal A, Brent C, Hölldobler B, Amdam G. Worker division of labor and endocrine physiology are associated in the harvester ant, Pogonomyrmex californicus. J Exp Biol. 2012;215:454-60 pubmed publisher
  3. Johnson R, Cover S. A taxonomic revision of the seed-harvester ant genus Pogonomyrmex (Hymenoptera: Formicidae) on Hispaniola. Zootaxa. 2015;3972:231-49 pubmed publisher
    ..schmitti darlingtoni Wheeler (= aterrimus) are synonomized. We also describe the queen of P. aterrimus and P. saucius, and provide information on biology, distribution maps, and a key to workers and queens. ..
  4. Smith A, Hölldober B, Liebig J. Cuticular hydrocarbons reliably identify cheaters and allow enforcement of altruism in a social insect. Curr Biol. 2009;19:78-81 pubmed publisher
    ..Cheaters are identified through information that is inherently reliable. ..
  5. Moore D, Liebig J. Mechanisms of social regulation change across colony development in an ant. BMC Evol Biol. 2010;10:328 pubmed publisher
    ..Mechanisms of conflict mediation observed in one phase of a social group's development cannot be generalized to all stages. ..
  6. Gadau J, Helmkampf M, Nygaard S, Roux J, Simola D, Smith C, et al. The genomic impact of 100 million years of social evolution in seven ant species. Trends Genet. 2012;28:14-21 pubmed publisher
    ..Altogether, these seven ant genomes open exciting new research avenues and opportunities for understanding the genetic basis and regulation of social species, and adaptive complex systems in general. ..
  7. Waters J, Fewell J. Information processing in social insect networks. PLoS ONE. 2012;7:e40337 pubmed publisher
  8. Penick C, Copple R, Mendez R, Smith A. The role of anchor-tipped larval hairs in the organization of ant colonies. PLoS ONE. 2012;7:e41595 pubmed publisher
    ..Based on our results, it is likely that many species exhibit this larval hanging behavior, and this could impact colony characteristics such as spatial organization and the care of developing larvae by nurse workers. ..
  9. Sasaki T, Pratt S. Groups have a larger cognitive capacity than individuals. Curr Biol. 2012;22:R827-9 pubmed publisher
    ..An isolated ant, on the other hand, must personally assess a larger number of sites to approach the same level of option coverage. By sharing the burden of assessment, the colony avoids overtaxing the abilities of its members. ..

    ..This shift may have facilitated the development of greater queen-worker dimorphism as well as multiple worker castes. ..
  2. Dolezal A, Johnson J, Hölldobler B, Amdam G. Division of labor is associated with age-independent changes in ovarian activity in Pogonomyrmex californicus harvester ants. J Insect Physiol. 2013;59:519-24 pubmed publisher
    ..The general finding that ovarian physiology is associated with social insect behaviors is consistent with the hypothesis that reproductive physiology may have played an important role in the evolution of social insect behavior...

    ..Therefore, the development of genetics in Harpegnathos establishes this ant species as a model organism to study the complexity of eusociality. ..

    ..We propose that corazonin is a central regulator of caste identity and behavior in social insects. ..
