SummarySeveral polymorphic allozyme loci (Amylase, Esterase-1, Esterase-3) have been used as genetic markers for the analysis of some aspects of social behaviour in two colour forms (actually sibling species) of meat ants,Iridomyrmex purpureus. A small amount of data suggests that haploid males are probably produced from eggs laid by the queen, and not by the workers. It appears that a substantial proportion of colonies of bothI. purpureus sens. strict, and the blue form of meat ants, may… Expand

Colony dispersion and relationships of meat antsIridomyrmex purpureus and allies in an arid locality in south Australia
TLDR
The distributions of three “forms”, actually sibling species, of meat ant were studied near Morgan, South Australia, an area with mean annual rainfall of 230 mm, and it was suggested that the numbers of individuals and species of other taxa active on the soil surface, predominantly Collembola, were affected by numbers of ants. Expand
Intracolony relatedness and polydomy in the Australian meat ant, Iridomyrmex purpureus
TLDR
Testing the genetic and spatial structure of polydomous colonies of Iridomyrmex purpureus in New South Wales, Australia revealed high relatedness within all but one of the colonies, indicating that the workers are mostly produced by one, singly inseminated queen, and polydomy in this population therefore is not associated with polygyny. Expand
Colony founding, queen dominance and oligogyny in the Australian meat ant Iridomyrmex purpureus
TLDR
A striking antagonistic behavior among coexisting queens in young colonies of the Australian meat ant is discovered, in the form of ritualized antennation bouts, which result in a reproductive rank order in which dominant queens inhibit egg-laying by subordinates, but escalation into physical fighting is rare. Expand
Conflict resolution strategies in meat ants (Iridomyrmex purpureus): ritualised displays versus lethal fighting
Our understanding of the evolution of display as a conflict strategy derives from extensive theoretical and empirical studies of non-social animals. Surprisingly, such an approach has seldom beenExpand
Australian ant research: fabulous fauna, functional groups, pharmaceuticals, and the Fatherhood
TLDR
The history of describing the Australian ant fauna is outlined, the resources that are available for identifying and researching them are documented, and a framework for understanding the dynamics of Australian ant communities is outlined. Expand
Unexpected, well-developed nestmate recognition in laboratory colonies of polygyne imported fire ants (Hymenoptera: Formicidae)
TLDR
Hypotheses to account for the acute intraspecific discrimination observed in the laboratory of the imported fire ant are presented and empirical testing of these hypotheses will illuminate ecological constraints and proximate mechanisms underlying the reduced intercolony discrimination associated with natural polygyne colonies of this and other ant species. Expand
Defense of termitaria by termitophilous ants
TLDR
Many termite colonies cohabiting with those two ant species were vigorous, suggesting that this ant-termite relationship is mutualistic; thus, the ants were provided nest sites and probably even food and the termites were protected from destructive natural enemies. Expand
Comparative Analysis of Worker Reproduction and Policing in Eusocial Hymenoptera Supports Relatedness Theory
TLDR
This analysis provides strong overall support for the theory that relatedness affects kin conflict over male parentage and shows that a significantly higher percentage of the males are workers’ sons in species where the workers are more related to other workers' sons. Expand
Ants build transportation networks that optimize cost and efficiency at the expense of robustness
TLDR
It is proposed that meat ant networks are an ideal model system for the development of network optimization heuristics after it was found that meat ants built low-cost trail networks that were relatively efficient. Expand

TLDR
Differences in gene frequency between sympatric populations of the red and blue forms of I. purpureus are observed, confirming their reproductive is isolation and sibling species status. Expand

Electrophoretic Variation of Amylase in Meat Ants, Iridomyrmex Purpureus, and Its Taxonomic Significance.
TLDR
Amylase isozymes in natural populations of Iridomyrmex purpureus (F. p. Sm.) in South Australia were found to be controlled by a polymorphic gene locus with four alleles, taken as evidence that these forms do not interbreed in nature and so are separate species. Expand
THE Population Biology OF THE Meat ANT
TLDR
Data on the populations of the meat ant Iridomyrmex purpureus in the Canberra area are analysed and discussed and the process appears to be a more effective method of colony foundation than for a single queen to attempt to start a new colony on her own. Expand
Dispersion and History of a Population of the Meat Ant Iridomyrmex Purpureus (Hymenoptera: Formicidae).
TLDR
An isolated population was studied at Belair, in the Mt Lofty Ranges in South Australia, by mapping the distribution of nests and colony territories, which indicated that intercolonial competition was involved in the development of the distribution pattern. Expand
Short-Term Change in a Population of the Meat Ant Iridomyrmex Purpureus (Hymenoptera: Formicidae).
TLDR
Comparison of parts of the population from areas differing in aspect and drainage shows that colony size and structure are controlled by rates of growth and survival of nests, depending largely on summer and winter stress respectively. Expand

Alcohol dehydrogenase polymorphism in Apis mellifera
TLDR
A polymorphic system of ADH isozymes is described in the honeybee Apis mellifera, and two different regions of activity were observed in the same samples, in the absence of the coenzyme. Expand
