Antagonistic Coevolution and Sex
- BiologyEvolution: Education and Outreach
- 2009
The reasons for why sex is anomalous for evolutionary theory, the rationale underlying the Red Queen hypothesis, and some empirical studies of the RedQueen hypothesis using a freshwater snail are presented.
Parasite Selection and the Fitness of Sexual Reproduction
- Biology
- 2015
The findings suggest that parasite selection can indeed operate on reproductive mode and are consistent with theory and a prior field study indicating that the direction of parasite selection is variable, such that parasites periodically select against sexual reproduction.
A review of Red Queen models for the persistence of obligate sexual reproduction.
- Biology, PsychologyThe Journal of heredity
- 2010
A historical review of coevolutionary models for the evolutionary persistence of sexual reproduction focuses on the fate of obligately sexual populations facing competition with one or more obligately asexual clones, finding that models that incorporate more ecological realism also seem more favorable to the parasite theory of sex.
Escape from the Red Queen: an overlooked scenario in coevolutionary studies
- Biology
- 2012
Sexual hosts are more difficult for coevolving parasites to ‘track’ over time, hence the “Red Queen hypothesis”, which refers to a passage in Lewis Carroll's ‘Through the Looking Glass’ in which the Red Queen tells Alice: ‘it takes all the running you can do, to keep in the same place’.
The Geographic Mosaic of Sex and Infection in Lake Populations of a New Zealand Snail at Multiple Spatial Scales
- BiologyThe American Naturalist
- 2013
It is found that parasite-mediated selection contributes to the long-term coexistence of sexual and asexual individuals in coevolutionary hotspots, and that the “warmth” of hotspots can vary on small spatial scales.
The ecology of sexual reproduction
- Biology, PsychologyJournal of evolutionary biology
- 2014
The evidence from natural populations and from laboratory experiments point to antagonistic coevolution as a potent and possibly ubiquitous force of selection favouring cross‐fertilization and recombination.
Sex, Death, and the Red Queen
- BiologyScience
- 2011
In laboratory experiments, Morran et al. grew several populations of nematode worms, some with and some without a bacterial parasite, to provide the most definitive support yet for the Red Queen's answer to why sex evolved.
Host–parasite coevolution induces selection for condition‐dependent sex
- BiologyJournal of evolutionary biology
- 2012
A population genetic model of a host population coevolving with a parasite population, where the parasites are haploid and the hosts either haploid or diploid, shows that in the large majority of the parameter space, infection‐dependent sex is more successful than infection‐independent sex.
Infection Dynamics in Coexisting Sexual and Asexual Host Populations: Support for the Red Queen Hypothesis*
- BiologyThe American Naturalist
- 2014
This study evaluated the prevalence of infection by a sterilizing trematode in a natural population of freshwater snails that was composed of both sexual and asexual individuals and found that at most sites and over most years, the sexual population was less infected than the coexisting asexual population.
When does parasitism maintain sex in the absence of Red Queen Dynamics?
- BiologybioRxiv
- 2020
Which host and parasite characteristics are most important for the maintenance of sex in the absence of RQD are revealed, and empirically testable predictions for how demography and epidemiology mediate competition between sex and asex are provided.

Geographic structure and dynamics of coevolutionary selection
- Environmental Science, BiologyNature
- 2002
It is confirmed that current coevolutionary selection in interspecific interactions can be highly divergent across both narrow and broad geographic scales, thereby fuelling continuing coev evolution of taxa.
PARASITES, SEX, AND EARLY REPRODUCTION IN A MIXED POPULATION OF FRESHWATER SNAILS
- BiologyEvolution; international journal of organic evolution
- 1995
Examining the predictions of these theories in a single population of freshwater snails (Potamopyrgus antipodarum), which contains a mixture of obligately sexual and obligately parthenogenetic females, found the results were in agreement with both theories.
Adaptation varies through space and time in a coevolving host–parasitoid interaction
- BiologyNature
- 2004
It is shown that gene flow across a spatially structured landscape alters coevolution of parasitoids and their hosts and that the resulting patterns of adaptation can fluctuate in both space and time.
Diverse, endemic and polyphyletic clones in mixed populations of a freshwater snail (Potamopyrgus antipodarum)
- Biology
- 1995
Protein electrophoresis was used to determine the source and diversity of clones in a freshwater snail in four glacial lakes in which sexual and clonal females were thought to coexist, and showed that repeated mutation to parthenogenetic reproduction since the Pleistocene has introduced a different and diverse set of clone in all four lakes.
THE GEOGRAPHY OF COEVOLUTION: COMPARATIVE POPULATION STRUCTURES FOR A SNAIL AND ITS TREMATODE PARASITE
- BiologyEvolution; international journal of organic evolution
- 1996
Gene flow and the genetic structure of host and parasite populations are critical to the coevolutionary process, including the conditions under which antagonistic coevolution favors sexual…
Coevolution between hosts and parasites with partially overlapping geographic ranges
- BiologyJournal of evolutionary biology
- 2003
A spatially explicit genetic model for a host that overlaps with a parasite in only part of its geographical range shows that there is a critical amount of overlap beyond which reciprocal selection leads to a coevolutionary response in the host.
Interactions between Genetic Drift, Gene Flow, and Selection Mosaics Drive Parasite Local Adaptation
- BiologyThe American Naturalist
- 2008
This work provides a general expression for parasite local adaptation that allows local adaptation to be partitioned into the contributions of spatial covariances between host and parasite genotype frequencies within and between habitats, and shows that genetic drift can dramatically increase the level of parasiteLocal adaptation under some models of specificity.
GENETIC STRUCTURE OF COEXISTING SEXUAL AND CLONAL SUBPOPULATIONS IN A FRESHWATER SNAIL (POTAMOPYRGUS ANTIPODARUM)
- Environmental Science, BiologyEvolution; international journal of organic evolution
- 1996
It is suggested that habitat specialization by clones, as well as parasite‐mediated selection against common clones, are important factors affecting the structure of this mixed population of sexual and clonal snails.
Host Sex and Local Adaptation by Parasites in a Snail‐Trematode Interaction
- BiologyThe American Naturalist
- 2004
The results demonstrate that the parasites are adapted, on average, to infecting their local host populations and suggest that they may be a factor in selecting against common host genotypes in natural populations.
Benefits and handicaps of sexual reproduction.
- Biology
- 1980
According to theories of regulation of recombination systems, a wide array of structural and ecological features of organisms, including sexuality vs. asexuality, are adjusted together to produce a supposedly optimal supply of genetic recombinants.
