Recent advances in army ant biology (Hymenoptera: Formicidae)
@inproceedings{Kronauer2009RecentAI, title={Recent advances in army ant biology (Hymenoptera: Formicidae)}, author={Daniel J C Kronauer and Quartier UNIL-Sorge}, year={2009} }
Arm y ants are dominant social hunters of invertebrates and thereby play an integral role in tropical ecosystems. They are defined by a suite of evolutionarily interrelated physiological, behavioural and morphological traits, the army ant adaptive syndrome: they are obligate group predators, they frequently relocate their nests, and their permanently wingless queens found new colonies accompanied by workers. If this functional definition is applied rather than a taxonomic one, army ants have…

Army-ant following in Neotropical birds: A review and prospectus
- Biology, Environmental ScienceOrnithology
- 2021
It is argued that this complex system of army-ant following birds provides unique and underappreciated opportunities for testing hypotheses in 5 main areas of interest: competitive interactions among attendant birds, cognitive and behavioral adaptations for locating swarms, evolution of ant-following behavior, ecology, evolution, and biogeography.
Strict monandry in the ponerine army ant genus Simopelta suggests that colony size and complexity drive mating system evolution in social insects
- BiologyMolecular ecology
- 2011
Ponerine army ants of the genus Simopelta, which are distantly related but similar in general biology to other army ants, have strictly monandrous queens, suggesting that differences in mature colony size and social complexity may explain these striking discrepancies.
The genomic basis of army ant chemosensory adaptations
- BiologyMolecular ecology
- 2021
Evidence is provided that army ants and their relatives possess a suite of modifications in the chemosensory system that may be involved in behavioural coordination and prey selection during social predation, and lays the groundwork for future studies of army ant biology at the molecular level.
The adaptive significance of phasic colony cycles in army ants
- Biology, Environmental SciencebioRxiv
- 2016
This model provides the first quantitative framework for understanding the adaptive value of phasic colony cycles in ants and shows that cyclic reproduction is favored under conditions where per capita foraging costs decrease with the number of larvae in a colony.

The Evolution of Extreme Polyandry in Social Insects: Insights from Army Ants
- BiologyPloS one
- 2014
It is shown that extreme polyandry is not only an integral part of the army ant syndrome, but generally adaptive in social insects by improving genetic variance, even at the high end spectrum of mating frequencies.
Foraging behavior in the ant genus Messor (Hymenoptera: Formicidae: Myrmicinae)
- Biology
- 2013
This paper reviews foraging strategies and the underlying behavioral mechanisms found in species of Messor, a diverse genus of seed harvesting ants found in grasslands, semi-arid areas and savannahs in both the Old and New World.
The rise of army ants and their relatives: diversification of specialized predatory doryline ants
- BiologyBMC Evolutionary Biology
- 2013
The phylogenetic analyses provide only weak support for army ant monophyly and call into question a previous hypothesis that army ants underwent a fundamental split into New World and Old World lineages, which provides a basic framework for comparative biological analyses.

Antbirds parasitize foraging army ants
- Biology
- 2005
It is shown, through use of exclusion experiments, that ant-following birds are parasites on Eciton burchellii, significantly reducing the ants' success rate in capturing prey.

This work focuses on the characteristics of fission in the phylogenetically primitive ants Ponerinae in which both ergatoid queens and gamergates occur.

This study establishes the army ant N. esenbeckii as the only known predator capable of successfully attacking and killing mature as well as young colonies of Atta leaf-cutting ants.
High rates of army ant raids in the Neotropics and implications for ant colony and community structure
- Environmental Science
- 2003
The results suggest that army ant predation can affect both smaller average colony sizes and indeterminate colony growth, and with the density of potential prey (litter-nesting ant colonies), across sites.
DOES THE AFROTROPICAL ARMY ANT DORYLUS (ANOMMA) MOLESTUS GO EXTINCT IN FRAGMENTED FORESTS?
- Environmental Science
- 2006
ABSTRACT Swarm-raiding army ants are extremely polyphagous nomadic predators inhabiting tropical forests. They are considered keystone species because their raids can regulate the population dynamics…
Do army ant queens re-mate later in life?
- BiologyInsectes Sociaux
- 2007
Sperm counts for males and queens of both species show that army ant queens have to mate with several males to become fully inseminated, suggesting that sperm limitation by queens is unlikely to have been the prime reason for the evolution of high queen-mating frequencies in this group.

Results strongly indicate that the suite of behavioral and reproductive adaptations found in army ants throughout the world is inherited from a unique common ancestor, and did not evolve convergently in the New World and Old World as previously thought.
A molecular phylogeny of Dorylus army ants provides evidence for multiple evolutionary transitions in foraging niche
- BiologyBMC Evolutionary Biology
- 2007
The evolutionary transitions in foraging niche were more complex than previously thought, but the comparative analysis of worker morphology lends strong support to the contention that particular foraging niches have selected for very specific worker morphologies.
Sexual competition during colony reproduction in army ants
- Biology
- 1987
It is suggested that males resemble queens not as a form of deceitful mimicry but because under the influence of sexual selection they have come to use the same channels of communication to demonstrate their potential fitness to the workforce as those used by queens.
