Nest site selection is a frequent context for decision making in ants, but little is known of the criteria used to make a choice. We tested the nest site preferences of Leptothorax curvispinosus, both by measuring hollow acorn nests occupied in nature, and by inducing laboratory colonies to choose between artificial nests of different design. Three criteria were examined. (1) Entrance size: the ants preferred small entrance holes, presumably for their greater defensibility and crypsis. Natural…

Active modification of cavity nest‐entrances is a common strategy in arboreal ants

The majority of tropical arboreal ant species nest in tree cavities. These cavities, often produced initially by wood‐boring beetles, can be in live or dead wood and represent long‐lasting and highly

Behavioral mechanisms of collective nest-site choice by the ant Temnothorax curvispinosus

The ants’ behavior qualitatively matches that of T. albipennis, where models have shown that decentralized choice of the best site depends on quality-dependent recruitment delays, amplified by a quorum rule for initiating transport.

Temperature differences associated with colour do not determine where the acorn ant Temnothorax crassispinus (Hymenoptera: Formicidae) chooses to nest

During a field experiment, the choice of nest site by the acorn ant Temnothorax crassispinus, a species which lives in coniferous and mixed forests, was studied, and it was predicted that in early spring, dark coloured nest sites would be warmer and thus more frequently occupied by ant colonies.

Queen location and nest site preference influence colony reunification by the ant Temnothorax rugatulus

It is shown that colonies balance multiple factors when reaching consensus, and that preferences for physical features of the environment can outweigh the queen’s influence.

Construction of nest mound and preference for it during relocation in an Indian ant Diacamma indicum

Ants living in subterranean nests face the challenge of nest flooding and require to combat this recurring issue. The tropical Ponerine ant species, Diacamma indicum, living in simple nests with a

Different nest entrance architecture by Colobopsis and Temnothorax ants colonizing oak galls

This study focuses on oak galls induced by the cynipid wasp Andricus quercustozae and secondarily colonized by two ant species, Colobopsis truncata and Temnothorax italicus.

The effect of prior experience on nest site evaluation by the ant Temnothorax curvispinosus

Nest Site Selection during Colony Relocation in Yucatan Peninsula Populations of the Ponerine Ants Neoponera villosa (Hymenoptera: Formicidae)

The ponerine ant Neoponera villosa workers seems to depend on innate preferences but familiarization with plant stimuli is not excluded, and chemical cues and plant structure play an important role in nest site selection.

Deterioration in nest quality triggers relocation without affecting its dynamics in an ant

The manner in which the colonies move to improve their nests is comparable to the dynamics of relocation when the old nest is totally destroyed as the costs of occupying a sub-optimal nest presumably outweigh the costs associated with relocation.

In-nest behavior by tandem recruiters of the ant Temnothorax rugatulus: effects of context and quality

It is hypothesized that tandem recruiters in the ant Temnothorax rugatulus share information about both target type (food vs. nest) and quality and this behavior is investigated inside the home nest, where they have many interactions with nestmates before leading a follower to the target.



Nest site limitation and colony takeover in the ant Leptothorax nylanderi

Investigation of the colony and population structure of the small, mynnicine ant Leptothorax (Myrafant) nylanderi in a deciduous forest near Wurzburg, Germany, where nest sites appear to be strongly limited, finds that nest sites become scarce in summer and both established colonies and young founding queens face a severe shortage of suitable nest sites.

Individual and collective decision-making during nest site selection by the ant Leptothorax albipennis

These small colonies make use of a distributed mechanism of information processing, but also take advantage of direct decision-making by well-informed individuals, which may reflect the stringent demand for unanimous decisions by house-hunting colonies of any size.

Spatial relationships within nests of the ant Leptothorax unifasciatus (Latr.) and their implications for the division of labour

Results from randomization tests demonstrated that the individual workers in L. unifasciatuscolonies had movement zones of limited area where each worker performed the tasks within her spatial fidelity zone, which was flexibly organized along the continuum of SFZs.

Size-Dependent Nest Site Choice by Cavity-Dwelling Ants

Nest site choice by cavity-dwelling ants of north temperate deciduous forests was studied at two sites in the northeastern United States, and two numerically dominant ant species chose different cavity sizes in experiments employing artificial nest sites.

Nest site selection and nest-building behaviour in domestic fowl

Resource location and structural properties of the nestbox as determinants of nest-site selection in the golden hamster

It is shown that hamsters can decrease foraging costs by setting their nests in the nestbox nearest to the food and/or nestmaterial sources, and that hoarding costs are taken into account in the choice process.


The strongest evidence of adaptive response to nest fate was higher nest density on an island where nest success was relatively high, and the strongestEvidence of natural (phenotypic) selection with data for six species of ducks was tested.

Population Studies of Two Species of Ants, Leptothorax Longispinosus Roger and Leptothorax Curvispinosus Mayr

Social insects are valuable for population studies because of the fact that each colony is a closed unit of society which shows all the phases of population phenomena of incipiency, growth, and decline.

Gaseous templates in ant nests.

There is surprising convergence between the period of cycles of synchronously active ants and the time taken for CO2 levels to equilibrate; and the qualitatively distinct regions of the "dynamic template" correspond to regions occupied by different groups of ants.
