Sexual reproduction can lead to major conflicts between sexes and within genomes. Here we report an extreme case of such conflicts in the little fire ant Wasmannia auropunctata. We found that sterile workers are produced by normal sexual reproduction, whereas daughter queens are invariably clonally produced. Because males usually develop from unfertilized maternal eggs in ants and other haplodiploid species, they normally achieve direct fitness only through diploid female offspring. Hence… Expand
Meiotic recombination dramatically decreased in thelytokous queens of the little fire ant and their sexually produced workers.
TLDR
It is suggested that the combination of automixis with central fusion and a major decrease in recombination rates allows clonal queens to benefit from thelytoky while avoiding the potential inbreeding depression resulting from the loss of heterozygosity during Automixis. Expand
Genetic determination of female castes in a hybridogenetic desert ant
TLDR
It is shown that the association between genotype and caste in this species is maintained by a ‘hard‐wired’ genetic caste determination system, whereby nonhybrid genomes have lost the ability to develop as workers. Expand
RARE SEXUAL REPRODUCTION EVENTS IN THE CLONAL REPRODUCTION SYSTEM OF INTRODUCED POPULATIONS OF THE LITTLE FIRE ANT
TLDR
Although the main reproduction system in New Caledonia remained clonality for both male and female reproductives, it was found that rare sexual reproduction events that led to the production of both new queen and male clonal lineages were found. Expand
RARE SEXUAL REPRODUCTION EVENTS IN THE CLONAL REPRODUCTION SYSTEM OF INTRODUCED POPULATIONS OF THE LITTLE FIRE ANT
A unique reproductive system has previously been described in Wasmannia auropunctata, a widespread invasive ant species, where males are produced clonally, female queens are parthenogens, and femaleExpand
Males are here to stay: fertilization enhances viable egg production by clonal queens of the little fire ant (Wasmannia auropunctata)
TLDR
The data suggest that physiological constraints, such as the requirement for insemination, must be considered in regard to evolution of reproduction systems, in addition to ecological data and theoretical considerations of fitness. Expand
Sib mating without inbreeding in the longhorn crazy ant
TLDR
The complete segregation of the male and female gene pools allows the queens to circumvent the costs associated with inbreeding and therefore may act as an important pre-adaptation for the crazy ant's tremendous invasive success. Expand
Sex and clonality in the little fire ant.
TLDR
This work found that traditional sexual populations occurred in W. auropunctata and are likely the recent source of neighboring clonal populations, and investigates the origins of female parthenogenesis and male clonality. Expand
Clonal reproduction and genetic caste differences in a queen-polymorphic ant, Vollenhovia emeryi
TLDR
The queen-polymorphic ant Vollenhovia emeryi might provide an interesting model system to trace the evolution of unusual caste and sex determination systems. Expand
Evolutionary biology: Males from Mars
TLDR
An extreme case of sexual conflict has been unearthed in the little fire ant Wasmannia auropunctata, which effectively results in a complete separation of the male and female gene pools. Expand
Lifelong commitment to the wrong partner: hybridization in ants
TLDR
The morphological similarity of most ant males, perhaps resulting from the lack of sexual conflict, may similarly contribute to the commonness of hybridization and may thus be an option for queens when conspecific mates are not available. Expand

Mating frequency of ant queens with alternative dispersal strategies, as revealed by microsatellite analysis of sperm
TLDR
This study provides no support to the hypotheses that multiple mating is beneficial because it increases genetic variability within colonies and occasional multiple mating by F. paralugubris queens may have no adaptive significance. Expand
Conditional Use of Sex and Parthenogenesis for Worker and Queen Production in Ants
TLDR
By selectively using sex for somatic growth and parthenogenesis for germline production, C. cursor has taken advantage of the ant caste system to benefit from the advantages of both sexual and asexual reproduction. Expand
Sexually antagonistic male adaptation triggered by experimental arrest of female evolution
TLDR
It is shown that when female D. melanogaster are experimentally prevented from coevolving with males, males rapidly adapt to the static female phenotype, which leads to a reduction in female survivorship, which is mediated by an increased rate of remating and increased toxicity of seminal fluid.

Complex hybrid origin of genetic caste determination in harvester ants
TLDR
It is shown that genetic caste determination evolved in these populations after complex hybridization events in Pogonomyrmex barbatus and P. rugosus, and seems to be evolutionarily stable. Expand

In this report the psr trait was shown to be caused by a supernumerary chromosome, which contains at least three repetitive DNA sequences that do not cross-hybridize to each other or to the host genome. Expand

TLDR
Evidence of intra-nest kin-recognition mechanisms implies a long evolutionary history of discrepant reproductive interests among colony members resulting from multiple mating, in view of the potential disadvantages stemming from polyandry. Expand

TLDR
It is argued that intragenomic conflict might be an important evolutionary force, and may influence the evolution of sex determining systems, sex allocation systems and post-zygotic isolating mechanisms. Expand
