Summary: Colonies of the monogyne social form of the red imported fire ant, Solenopsis invicta, may contain half a million workers per nest. Spatially organizing such a large group within the confines of a single nest requires a pragmatic architectural design. The morphology of field mounds and subterranean nest chambers of S. invicta were determined using several cast methods. The above-ground portion of a fire ant nest, the mound, consisted of a dense matrix of narrow tunnels. Below ground… Expand

Discovering the Giant Nest Architecture of Grass-Cutting Ants, Atta capiguara (Hymenoptera, Formicidae)
TLDR
The architecture of three A. capiguara nests from a fragment of Cerrado in Botucatu, São Paulo, Brazil is investigated to contribute to a better understanding of the so far unknown nest architecture of this grass-cutting ant. Expand
Testing the effect of a nest architectural feature in the fire ant Solenopsis invicta ( Hymeno ptera : Formicidae )
When natural fire ant colonies (Solenopsis invicta) are sampled over five orders of magnitude of colony size, their production efficiency (new biomass per current biomass) remains constant, whereasExpand
Nest Architecture and Colony Growth of Atta bisphaerica Grass-Cutting Ants
TLDR
It is demonstrated for A. bisphaerica that nest development in terms of chamber volume is similar to the increase in number of colony workers, and this contributes to a better understanding of Atta nest architecture. Expand
Nest-seeking rock ants (Temnothorax albipennis) trade off sediment packing density and structural integrity for ease of cavity excavation
TLDR
Overall, colonies only showed a significant preference for cavities that were fastest to excavate over those that were slowest, suggesting that the speed of decision making and moving appears paramount over the suitability of the sediment for forming an enclosing wall. Expand
Effect of the presence of brood and fungus on the nest architecture and digging activity of Acromyrmex subterraneus Forel (Hymenoptera, Formicidae)
TLDR
The results do not support the hypothesis that the fungus garden and/or brood are local stimuli for nest excavation or that they mold the internal architecture of the nest, and the same does not apply to A. subterraneus. Expand
Nest architecture of the ant Formica pallidefulva: structure, costs and rules of excavation
TLDR
The architecture of underground ant nests was studied in the ant Formica pallidefulva, which consist of more or less vertical shafts that bear chambers, which are top-heavy and declining exponentially with depth. Expand
Diversity ffect of the presence of brood and fungus on the nest architecture nd digging activity of Acromyrmex subterraneus Forel ( Hymenoptera , ormicidae ) arlos
This study investigated the stimuli that trigger digging behavior in Acromyrmex subterraneus during nest building. The hypothesis was that the presence of the fungus garden and/or brood triggers theExpand
Digging beneath the surface: incipient nest characteristics across three species of harvester ant that differ in colony founding strategy
TLDR
Results reveal degree of claustrality is correlated across species with several nest initiation characteristics that together may represent different colony founding syndromes. Expand
The nest architecture of the Florida harvester ant, Pogonomyrmex badius
TLDR
The architecture of the subterranean nests of the Florida harvester ant, Pogonomyrmex badius, was studied through excavation and casting and it was found that older workers moved upward to assume positions in the upper parts of the nest, much as in the colonies from which they were taken. Expand
Excavated substrate modulates growth instability during nest building in ants
TLDR
It is found that transitions and excavation cessation follow area–response thresholds: the shape transitions take place and the digging activity stops when the dug area reaches the corresponding threshold values, which are independent of nest shape and material. Expand

Sociometry and sociogenesis of colony-level attributes of the Florida harvester ant (Hymenoptera : Formicidae)
TLDR
The seasonal patterns of colony fat reserves suggest that colonies draw on these reserves to overwinter and produce sexuals, then they rebuild the reserves during the summer, suggesting that changes in colony composition and function lead to better nutrition. Expand

A study of new colonies of Solenopsis invicta Buren showed that from their inception in early May until fall when weather stops development, the colonies had grown from a single queen and 15–20Expand
Effects of colony-level attributes on larval feeding in the fire ant, Solenopsis invicta
TLDR
Investigation of the effects of colony size and worker:brood ratio on the rate of worker-to-larva trophallaxis in the fire ant reinforced previous research demonstrating that social feeding in theFire ant emerges from localized interactions rather than mass communication. Expand
Sociometry and Sociogenesis of Colonies of the Fire Ant Solenopsis Invicta During One Annual Cycle
TLDR
Fire ant colonies reached their annual maximum population size in midwinter and their maximum biomass in spring and declined to a midsummer minimum, showing that the transition from the ergonomic to the reproductive stages is sharp, and that colonies must grow in order to produce more sexuals.

Self-organizing nest construction in ants: individual worker behaviour and the nest's dynamics
TLDR
This model confirms that a surprisingly small and simple set of behavioural rules are not only sufficient for wall construction but also for the formation of one or more nest entrances, and predicts that the nests of these ants are likely to exhibit interesting dynamics, in which the tendency to build a new larger nest may lag behind growth of the population that the nest has to house.

TLDR
There is little, if any, morphspecific task specialization by workers suggesting worker size variance is a colony-level adaptation permitting maintenance of a large and constant worker force during periods of resource fluctuation. Expand
Impact of temperature on colony growth and developmental rates of the ant, Solenopsis invicta
TLDR
It appears that temperature-adjusted development rates of ants and other social Hymenoptera are quite similar, and Nanitic brood developed about 35% faster than did minor worker brood, an important benefit for founding colonies. Expand

TLDR
Evidence was provided in support of the hypothesis that the growth of the worker population was autocatalytic, the numbers at any time playing a large part in determining the amount of growing juvenile replacement material. Expand
What is the function of encounter patterns in ant colonies?
TLDR
The results show that in undisturbed conditions, contact rate was not random, and the magnitude of the increase depended on proportions, not numbers of non-nestmates present, suggesting that contact rate may be a cue to nestmate density. Expand
