Summary 1 We tested for density-dependent regulation of biomass in a population of the fire ant Solenopsis invicta and examined the mechanisms of population recovery following replicated colony removals. 2  All colonies were killed within the core area (1018 m2) of six plots, while six additional plots served as undisturbed controls. Over the next 5 years, colonies were mapped several times per year and the biomass of each colony was estimated from the volume of the nest-mound. 3…

Experimental analysis of territory size in a population of the fire ant Solenopsis invicta

Results show that territory areas in S. invicta are strongly affected by the relative fighting ability of neighboring colonies but provide no evidence that colonies adjust territory area in response to short-term changes in the availability of food.

Experimental evidence that the introduced fire ant, Solenopsis invicta, does not competitively suppress co-occurring ants in a disturbed habitat.

The results are contrary to classical predictions and indicate that S. invicta is not a superior competitor that suppresses native ants, and that the low diversity and abundance of native ants in degraded ecosystems does not result from interaction with fire ants.

Abundance and Distribution of the Invasive Ant, Solenopsis invicta (Hymenoptera: Formicidae), in Cypress Savannas of North Carolina

Cypress savannas join a growing list of habitats, having wet sandy or loamy soils and little canopy, that have become invaded by S. invicta in the absence of anthropogenic soil disturbances and could have important direct and indirect effects on the native communities.

Genetic and morphological variation over space and time in the invasive fire ant Solenopsis invicta

Social insects are among the most successful and damaging of invasive taxa. We studied spatial and temporal variation in two traits, colony genetic structure and worker mass, associated with social

The Biology and Natural History of Aphaenogaster rudis

The biology of these so-called rudis-group ant species, including details about their sociometry, productivity, natural history, and behavior, are synthesized here using published and newly collected data.

Rainfall, neighbors, and foraging: The dynamics of a population of red harvester ant colonies 1988‐2019

Changing climatic conditions are shaping how density mediates resource competition. Colonies of the seed-eating red harvester ant, Pogonomyrmex barbatus , live for about 30 years in desert grassland.

Frequent nest relocation in the ant Aphaenogaster araneoides: resources, competition, and natural enemies

This paper document several cycles of nest relocation in a population of the Central American ant Aphaenogaster araneoides and proposes that nest relocation is driven by the escape from natural enemies.

Intraspecific competition affects population size and resource allocation in an ant dispersing by colony fission.

Colonies adjust resource allocation and colony fission to the degree of intraspecific competition, and at the end of the experiment, colonies that derived from fission were smaller in the experimental than in the control plots, suggesting that the former had undergone fission at a smaller size than inControl plots, which presumably allowed them to colonize the emptied areas.



Territory area and colony size in the fire ant Solenopsis invicta

Mound volume, which can be quickly measured without disturbing the colony, provided a reasonable estimate of colony or worker biomass and explained most of the variance in territory size.

Spatial Model of Territorial Competition and Population Dynamics in the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae)

A simulation model of monogyne red imported fire ant populations that operates by competitive interactions of individual colony territories describes six major aspects of colony lite history: nest founding, brood raiding, territory expansion, queen death, possible requeening, and colony death.

Growth and Development of Colonies of the Red Imported Fire Ant, Solenopsis invicta

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 15–20

Density-Dependent Competition in Fire Ants: Effects on Colony Survivorship and Size Variation

Competition by brood raiding tended to increase the degree of size inequality among colonies, consistent with models and observations of «asymmetric competition» among sessile organisms.

Mechanisms of Interference and Foraging Among Colonies of the Harvester ant Pogonomyrmex Californicus in the Mojave Desert

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.

Colonization patterns of the leaf‐cutting ant, Atta bisphaerica Forel: evidence for population regulation

Following the nuptial flight, colonization patterns of queens of the leaf‐cutting ant, Atta bisphaerica, were studied by means of belt transects to find queen execution by conspecifics was greater in areas of mature colonies.

Ant predators of founder queens of Solenopsis invicta (Hymenoptera : Formicidae) in central Texas

Vials containing founder queens of the red imported fire ant, Solenopsis invicta Buren, were placed under the soil surface at four locations in central Texas to compare founder queen predation mortality and also to document ant predators of the queen.

Spatial distribution of Pogonomyrmex occidentalis : Recruitment, mortality and overdispersion

1. The western harvester ant Pogonomyrmex occidentalis is frequently the dominant insect species in the deserts and arid grasslands of western North America. 2. The lek mating system of this species

Comparison of Polygyne and Monogyne Red Imported Fire Ant (Hymenoptera: Formicidae) Population Densities

Overall, this study indicates that polygyne population densities are ≈2 times larger on average than monogynepopulation densities.

Sociometry and Sociogenesis of Colonies of the Fire Ant Solenopsis Invicta During One Annual Cycle

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.
