Abstract Colonies of the red harvester ant, Pogonomyrmex barbatus, do various tasks outside the nest. There is a daily temporal pattern in the numbers of ants engaged in each of five activities: foraging, nest maintenance, patrolling, midden work and covening. Perturbations were carried out in the field to investigate how the daily round changes in respose to environmental events and colony needs. Intefering with nest maintenance, foraging or both caused changes in the temporal patterns in all… 
Group-level dynamics in harvester ants: young colonies and the role of patrolling
TLDR
Comparisons and differences in the flexibilities of colonies 3 or more years apart are organizational rather than a result of the accumulated experience of particular individuals, and suggest a more strongly homeostatic response to perturbations in older colonies than in younger ones.
The structure of foraging activity in colonies of the harvester ant, Pogonomyrmex occidentalis
TLDR
The duration of foraging during this study was correlated with the duration ofForaging measured 6 years earlier, suggesting that it is an aspect of colony phenotype, and some colonies have a consistent advantage in foraging.
The Regulation of Foraging Activity in Red Harvester Ant Colonies

TLDR
It is suggested that whether a colony forages at all on a given day depends on conditions detected early by patrollers but that once foraging begins, the intensity of foraging does not track, on an hourly timescale, how quickly foragers can find food.
Variation in the transition from inside to outside work in the red harvester ant Pogonomyrmex barbatus
TLDR
High variability in task sequence in laboratory colonies of the red harvester ant, Pogonomyrmex barbatus, suggests that requirements imposed by variable external conditions and colony needs in the field have a strong influence on task sequence.
How colony growth affects forager intrusion between neighboring harvester ant colonies

TLDR
Colonies of the harvester ant adjust the direction and length of foraging trails in response to the foraging behavior of their conspecific neighbors, and foraging area may be of greater current or prospective value for younger, smaller, quickly growing colonies than for older, larger ones of stable size.
Activity Patterns of Harvester Ants Pogonomyrmex pronotalis and Pogonomyrmex rastratus in the Central Monte Desert, Argentina
TLDR
The results suggest that temporal changes in surface activity respond mainly to soil temperature fluctuations, and at intermediate temperatures, temperature appears not to be a good predictor of daily and seasonal activity fluctuations.
Intraspecific competition through food robbing in the harvester ant,Messor aciculatus (Fr. Smith), and its consequences on colony survival
TLDR
The results of field observations and experiments suggest the existence of a dominance order among the neighbors of the harvester ant, Messor aciculatus, and the influence of ritualized combat and food robbing on colony activities is discussed.
Hydrocarbons on Harvester Ant (Pogonomyrmex barbatus) Middens Guide Foragers to the Nest
TLDR
It is shown that hydrocarbons found on the mound of Pogonomyrmex barbatus nests facilitate the return of foragers to the nest, and the chemical environment of the nest mound contributes to the regulation of foraging behavior in harvester ants.
Nest Maintenance Activity of Dinoponera quadriceps in a Natural Environment
TLDR
The results indicate the existence of an annual variation in the nest maintenance activity of D. quadriceps associated with environmental variables, however, it occurs equally both at night and day, countering the hypothesis that there is a daily rhythm.
Nest-plugging: interference competition in desert ants (Novomessor cockerelli and Pogonomyrmex barbatus)
TLDR
Nest-plugging by N. cockerelli decreases the foraging capacity of P. barbatus colonies and means that these colonies do not compensate for late emergence or events impeding foraging by increasing foraging rate.

Mechanisms of Interference and Foraging Among Colonies of the Harvester ant Pogonomyrmex Californicus in the Mojave Desert
TLDR
Following an encounter involving physical struggle, ants returned to and remained in their nests for an extended period of time, thereby reducing seed input to the colony, thus indicating that such aggression may have a substantial impact on colony size.
Response to predation by colonies of the Florida harvester ant, Pogonomyrmex badius. [1965 studies]
TLDR
Although the forager population was greatly reduced, the colonies were able to survive until more foragers could be produced and an adaptive strategy is possible because of a highly developed social behavior which results in a well-defined division of labor within the ant colony.
Social responses to variation in food supply and nest suitability in ants (Tapinoma erraticum)
TLDR
The existence of types of social organization which are specific to each of the activities performed is indicated: the transport behaviour of T. erraticum workers does not appear to be agedependent, unlike feeding behaviour.

TLDR
In the present study, the behavior of exterior workers of the harvester ant Pogonomyrmex badius is classified into a more detailed set oftasks than in previous studies of the genus.
Daily Rhythms in Social Activities of the Harvester Ant,Pogonomyrmex Badius
Daily cycles in behavior are well known throughout the animal kingdom. There is some evidence that the activities of ant colonies are temporally organized so that, at a given time of day, a certain
Factors Affecting Foraging Activity in Chihuahuan Desert Harvester Ants
TLDR
Foraging in harvester ants seemed to be primarily affected by forage availability, secondarily by microclimate, with historical factors and interspecific competition as contributing parameters in some species.

TLDR
It is concluded that evolution of a long—term strategy in horned lizards is unlikely and three characteristics of P. Desertorum colonies are attributed to three conditions.

TLDR
Colonies of Pogonomyrmex rugosus exhibited a mixed foraging strategy, with the most distinct feeding columns occurring during a period of peak seed abundance.

TLDR
The results illustrate how indirect interactions among species at a single trophic level may play a significant role in organizing natural communities.
