..., but also establish that rescue, heretofore overlooked in analyses of division of labor, is a true specialization, an ant version of first responders. Moreover, this specialization emerges as early as 5 days of age, and the frequency of rescuers remains constant across ants' age ranges. The extremely broad...

...Margarita Orlova; Jesse Starkey; Etya Amsalem ABSTRACT The mechanisms that maintain reproductive division of labor in social insects are still incompletely understood. Most studies focus on the relationship between adults, overlooking another important stakeholder – the juveniles. Recent studies...

...Sarah P. Lawson; Salena L. Helmreich; Sandra M. Rehan ABSTRACT By manipulating resources or dispersal opportunities, mothers can force offspring to remain at the nest to help raise siblings, creating a division of labor. In the subsocial bee Ceratina calcarata , mothers manipulate the quantity...

... ( Beshers and Fewell, 2001 ). Among these models, the response-threshold model has played an influential role in the explanation of the division of labor in social insects. It posits that differences in sensitivity to external stimuli exist between individuals and that individuals highly sensitive...

...Adam G. Dolezal; Colin S. Brent; Bert Hölldobler; Gro V. Amdam SUMMARY In Pogonomyrmex californicus harvester ants, an age-associated division of labor occurs in the worker caste, in which young workers perform in-nest tasks and older workers forage for food. Here, we tested whether this behavioral...
