The near-ubiquity of sexual reproduction in animal species has long been considered a paradox because sexually reproducing individuals transmit only half of their genome to their progeny. Here, we show that the ant Cataglyphis cursor circumvents this cost by using alternative modes of reproduction for the production of reproductive and nonreproductive offspring. New queens are almost exclusively produced by parthenogenesis, whereas workers are produced by normal sexual reproduction. By… Expand
Ant queens adjust egg fertilization to benefit from both sexual and asexual reproduction
TLDR
It is shown that queens of the ant Cataglyphis cursor maximize the transmission rate of their genes by regulating the proportion of fertilized and parthenogenetic eggs laid over time. Expand
Facultative use of thelytokous parthenogenesis for queen production in the polyandrous ant Cataglyphis cursor
TLDR
It is shown that the queen can also produce gynes sexually and may do so to offset the costs of asexual reproduction, andSimulations of gynes inbreeding level following one to ten generations of automictic thelytoky suggest that the queens switches between or combines thelyToky and sex, which may reduce the costsof inbreeding. Expand
Sex and Social Evolution
TLDR
Recent research suggests that queens of some ants and termites can solve this trade-off by the conditional use of sexual and asexual reproduction, whereby queens produce the next generation of queens by parthenogenesis but use sexual reproduction to produce workers. Expand
Queen Succession Through Asexual Reproduction in Termites
TLDR
A previously unknown termite breeding system in which both parthenogenesis and sexual reproduction are conditionally used is identified, showing how eusociality can lead to extraordinary reproductive systems and provide important insights into the advantages and disadvantages of sex. Expand
Sexual and Asexual Reproduction in Termites
TLDR
How eusociality, with its attendant caste structure and unique life histories, can generate novel reproductive and genetic systems with mixed modes of reproduction provides important insights into the advantages and disadvantages of sexual reproduction. Expand
Termite queens close the sperm gates of eggs to switch from sexual to asexual reproduction
TLDR
It is discovered that queens of the termite close micropyles (openings for sperm entry) of their eggs to produce parthenogenetic offspring in the presence of kings, the first identification, to the authors' knowledge, of the mechanism through which females control egg fertilization over time in diploid animals. Expand
Social Hybridogenesis in the Clonal Ant Cataglyphis hispanica
TLDR
A unique case of social hybridogenesis in the desert ant Cataglyphis hispanica is reported, where workers are produced exclusively from interbreeding between two distinct genetic lineages, whereas male and female sexuals are produced by asexual reproduction through parthenogenesis. 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
Repeated evolution of queen parthenogenesis and social hybridogenesis in Cataglyphis desert ants
TLDR
It is inferred that both the conditional use of sex and social hybridogenesis independently evolved multiple times in the genus Cataglyphis, and one new case in which sexual reproduction was conditionally used in the absence of dependent‐lineage reproduction is identified. Expand
Brood development into sexual females depends on the presence of a queen but not on temperature in an ant dispersing by colony fission, Aphaenogaster senilis
TLDR
It is shown that developing diploid larvae should have a preference for becoming a queen and having their own offspring, rather than becoming workers and rearing the offspring of other females, which constrains the possibility of fission in eusocial insects. Expand

TLDR

TLDR
It is hypothesize that the system of caste determination that is observed in the red harvester ant, Pogonomyrmex barbatus, segregates the population into two distinct genetic lineages, each of which has distinct alleles at the microsatellite locus and also has different alleles, it is proposed, at caste.

The reproductive cycle of the queenless ant pristoMyrmex pungens
TLDR
It is found that the virgin small workers can lay eggs and that these develop into further small workers, indicating that reproduction in P. pungens is carried out predominatly or, probably, wholly by the small workers and hence is thelytokous. Expand
Reproductive Harmony via Mutual Policing by Workers in Eusocial Hymenoptera
TLDR
Examination of the cause-effect relationship between queen mating frequency and worker policing indicates that worker policing is caused by queen polyandry but thatworker policing is unlikely to cause polyandries, although it may help stabilize it if police workers show behavioral dominance. Expand
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

TLDR
The possible evolutionary routes to parthenogenesis are reviewed based on a survey of the phylogenetic relationships between sexual and parthenogenetic lineages in a broad range of animals and the influences of these mechanisms on both the genetic properties and the ecological life styles of the resulting lineages are discussed.
