Genetic polyethism in leaf-cutting ants [PDF]
Behavioral Ecology, 2010 Females mating with multiple males (polyandry) is taxonomically widespread but is hard to explain in many animals in which it has no obvious direct benefits. In some, of which social insects are the best example, it is suggested that females benefit from the increased genetic diversity of their offspring.

How to coexist with fire ants: The roles of behaviour and cuticular compounds [PDF]
, 2013 tBecause territoriality is energetically costly, territorial animals frequently respond less aggressively toneighbours than to strangers, a reaction known as the “dear enemy phenomenon” (DEP).

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]
, 2013 Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Effect of trail bifurcation asymmetry and pheromone presence or absence on trail choice by Lasius niger ants [PDF]
, 2014 During foraging, ant workers are known to make use of multiple information sources, such as private information (personal memory) and social information (trail pheromones).

Genetic royal cheats in leaf-cutting ant societies [PDF]
Proceedings of the National Academy of Sciences, 2008 Social groups are vulnerable to cheating because the reproductive interests of group members are rarely identical. All cooperative systems are therefore predicted to involve a mix of cooperative and cheating genotypes, with the frequency of the latter being constrained by the suppressive abilities of the former.

Climate Change Influences Basidiome Emergence of Leaf-Cutting Ant Cultivars [PDF]
Journal of Fungi, 2021 Maintaining symbiosis homeostasis is essential for mutualistic partners. Leaf-cutting ants evolved a long-term symbiotic mutualism with fungal cultivars for nourishment while using vertical asexual transmission across generations. Despite the ants’ efforts to suppress fungal sexual reproduction, scattered occurrences of cultivar basidiomes have been ...
