Social complexity influences brain investment and neural operation costs in ants
@article{Kamhi2016SocialCI, title={Social complexity influences brain investment and neural operation costs in ants}, author={J. Frances Kamhi and Wulfila Gronenberg and Simon K A Robson and James F. A. Traniello}, journal={Proceedings of the Royal Society B: Biological Sciences}, year={2016}, volume={283} }
The metabolic expense of producing and operating neural tissue required for adaptive behaviour is considered a significant selective force in brain evolution. In primates, brain size correlates positively with group size, presumably owing to the greater cognitive demands of complex social relationships in large societies. Social complexity in eusocial insects is also associated with large groups, as well as collective intelligence and division of labour among sterile workers. However…

Worker brain development and colony organization in ants: Does division of labor influence neuroplasticity?
- BiologyDevelopmental neurobiology
- 2017
Comparison of macroscopic and cellular neuroanatomy in two ant sister clades with striking contrasts in worker morphological differentiation and colony‐level social organization suggests changes in the mushroom body with age are associated with division of labor, and therefore social complexity, in ants.
Social Complexity and Brain Evolution: Comparative Analysis of Modularity and Integration in Ant Brain Organization
- Biology, PsychologyBrain, Behavior and Evolution

It is found that colony size and social organization, key measures of social complexity, were only weakly correlated with brain modularity in these formicine ants, suggesting that brain organization may be shaped by the divergent life histories of the two study species.
Behavioral performance requirements for division of labor influence adaptive brain mosaicism in a socially complex ant

Investment in multi-sensory integration and motor requirements for task performance was estimated to be greatest for media workers whose leaf-harvesting repertoire involves the most diverse and demanding sensory and motor processes, including plant discrimination, leaf cutting, and fragment transportation.

Strongly polyphenic social insects provide excellent models to examine the neurobiological basis of division of labor. Turtle ants, Cephalotes varians, have distinct minor worker, soldier, and…
Behavior, brain, and morphology in a complex insect society: trait integration and social evolution in the exceptionally polymorphic ant Pheidole rhea
- BiologyBehavioral Ecology and Sociobiology

The early branching position of P. rhea in the phylogeny of Pheidole and patterns of worker phenotypic plasticity suggest this species exhibits an ancestral state of sociobiological and neurobiological organization that served as a ground plan for diversification in this ecologically dominant ant genus.
Brain evolution in social insects: advocating for the comparative approach

It is argued that measuring the role of sociality in brain evolution will benefit from attending to recent advances in neuroethology and adopting existing phylogenetic comparative methods employed in analysis of non-neural traits.
Brain Size, Metabolism, and Social Evolution
- Biology, PsychologyFrontiers in Physiology
- 2021
Using ants as eusocial insect exemplars, an analysis of brain evolution encompassing metabolism, brain size, and neuroarchitecture is proposed to understand how these traits scale with body size and correlate with social behavior.

The hypothesis that variation in task performance influences selection for mosaic brain structure, the independent evolution of proportions of the brain composed of different neuropils, is supported.
Socioecology and Evolutionary Neurobiology of Predatory Ants
- BiologyFrontiers in Ecology and Evolution

The socioecology of predatory ants and its influence on neuroanatomy is discussed, which provides the opportunity to separate the relative roles of diet and colony size and brain structure, and offer diverse novel systems to understand adaptive brain mosaicism and the neuronal regulation of predatory behavior.

It is argued that future work aiming to understand how animal behavior, cognition, and brains are shaped by the environment should focus on brain functions and identify neural circuitry correlates of social tasks, not only brain sizes.

It is shown that large relative brain size in birds is associated with pair-bond strength, itself a likely consequence of cooperation and negotiation between partners under high levels of parental investment, and that the evolution of both traits is contingent on biparental care.
