Driver Ants Invading a Termite Nest: Why Do the Most Catholic Predators of All Seldom Take This Abundant Prey?

  title={Driver Ants Invading a Termite Nest: Why Do the Most Catholic Predators of All Seldom Take This Abundant Prey?},
  author={Caspar Sch{\"o}ning and Mark W. Moffett},
Driver ants (i.e., epigaeic species in the army ant genus Dorylus, subgenus Anomma) are among the most extreme polyphagous predators, but termites appear to be conspicuously absent from their prey spectrum and attacks by driver ants on termite nests have not yet been described. Here, we report a Dorylus (Anomma) rubellus attack on a colony of the fungus‐growing termite Macrotermes subhyalinus that was observed during the dry season in a savannah habitat in Nigeria's Gashaka National Park. It… 


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

Species‐level predation network uncovers high prey specificity in a Neotropical army ant community

It is shown that prey specialization in army ants is unexpectedly high and prey niche overlap very small, and a spatiotemporal niche differentiation in army ant raid activity is uncovered.

Recent advances in army ant biology (Hymenoptera: Formicidae)

The aim of this review is to provide a synthesis of the most recent work on army ant biology, to outline an evolutionary scenario that connects the different aspects of army ant life-history, and to give some directions for future research.

Prey spectra of two swarm‐raiding army ant species in East Africa

It is demonstrated that the method of assessing prey spectra in terms of relative prey item numbers often produces biased results, and therefore recommend relative prey biomass as the more useful parameter.

Predation on insects on Tiwai, Sierra Leone

Tiwai is a wooded island in the river Moa near the Gola rainforest in eastern Sierra Leone, and a good number and variety of caterpillars have been found, including a species for which no caterpillar records existed.

Detection of Mitochondrial COII DNA Sequences in Ant Guts as a Method for Assessing Termite Predation by Ants

The data provide tentative support for the hypothesis that unspecialised termite predation by ants is widespread and highlight the use of molecular approaches for future studies of ant-termite food webs.

Should I stay or should I go now? Patch use by African army ant colonies in relation to food availability and predation

Testing if and how patch departure time of the aboveground-hunting army ant Dorylus molestus under field conditions is influenced by food availability and nest attacks by predators found it necessary to definitively determine whether food availability influences patch departure times and to elucidate the consequences of colony encounters.

Ant‐termite interactions: an important but under‐explored ecological linkage

It is inferred that ant predation on termites is the most important, most widespread, and most studied type of interaction and it will be necessary to quantify the efficacy both of particular ant species and of ant communities as a whole in regulating termite populations in different biomes.

Spatiotemporal resource distribution and foraging strategies of ants (Hymenoptera: Formicidae).

It is demonstrated that different foraging strategies are indeed associated with specific spatiotemporal resource attributes, and the general patterns described here can be used as a framework to inform predictions in future studies of ant foraging behavior.

Male-biased dispersal promotes large scale gene flow in a subterranean army ant, Dorylus (Typhlopone) fulvus

The well flying D. fulvus males appear to be the sex to promote large scale gene flow, and the species is indeed a species in which sex specific dispersal patterns and the mating system profoundly affect the population structure and phylogeography.



Combat between large derived societies: A subterranean army ant established as a predator of mature leaf-cutting ant colonies

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.

Army ant prey availability and consumption by chimpanzees (Pan troglodytes vellerosus) at Gashaka (Nigeria)

It is suggested that the chimpanzees in this population of the chimpanzee subspecies Pan troglodytes vellerosus in Nigeria do not harvest army ants from trails and do not use trails to locate nests, suggesting that army ant prey is not a fallback during periods of sparse availability of plant food, but quantitatively important throughout the year.

Predatory Behavior and Food Preferences of Driver Ants in Selected African Habitats

Aspects of predatory behavior and food preferences of three species of driver ants, Dorylus (Anomma) gerstaeckeri Emery, D. (A.) nigricans Illiger, and D. (A.) nigricans var. molesta (Gerstaecker),

Foraging of a hypogaeic army ant: a long neglected majority

D. laevigatus was found to construct stable hypogaeic trunk trail systems providing quick and easy access to all parts of its foraging area, and seems to follow a sustainable use of the soil fauna.

Behavioral ecology of the neotropical termite-hunting ant Pachycondyla (= Termitopone) marginata: colony founding, group-raiding and migratory patterns

It is concluded that P. marginata presents a rudimentary form of the so-called “army ant behavior”, which is highly developed in the subfamilies Dorylinae and Ecitoninae, and the associated high costs of migration are likely to prevent it from evolving a full army ant life pattern.

Reproductive success of Macrotermes bellicosus (Isoptera, Macrotermitinae) in two neighbouring habitats

It is suggested that the forest is a suboptimal habitat for M. bellicosus, whereas in forests it is comparatively rare and is only found in relatively open areas.

Evolution of allometries in the worker caste of Dorylus army ants

A detailed comparative analysis of the allometries of nine characters for ten species belonging to all six currently recognized subgenera and showing different life-styles suggests that shifts in ecological niche are linked with adaptations in these traits.

Habitat fragmentation, percolation theory and the conservation of a keystone species

Many species survive in specialized habitats. When these habitats are destroyed or fragmented the threat of extinction looms. In this paper, we use percolation theory to consider how an environment

Nigerian Chimpanzees (Pan troglodytes vellerosus) at Gashaka: Two Years of Habituation Efforts

It is reported on the first 2 years of a new long-term study from what is perhaps their last remaining stronghold: the Gashaka Gumti National Park, Nigeria, where chimpanzees are relatively tolerant of human observers and susceptible to a wide range of methodological, social and ecological factors.

A New General Catalogue of the Ants of the World

For every name that has ever been applied to ants, the book supplies a history and an account of current usage, together with a fully documented indication of the present-day classification.
