Cryptic intimate populations take into account hereditary variety and environmental success in a widely distributed, asexual fungus-growing ant

Abstract

Intercourse and recombination are main procedures in life producing diversity that is genetic. Organisms that rely on asexual propagation danger extinction because of the loss in genetic diversity in addition to incapacity to adapt to changing conditions that are environmental. The fungus-growing ant types Mycocepurus smithii had been regarded as obligately asexual because just parthenogenetic populations have now been gathered from widely separated localities that are geographic. Nevertheless, M. smithii is environmentally successful, most abundant in extensive circulation as well as the population densities that are highest of any fungus-growing ant. Right here we report that M. smithii actually comes with a mosaic of asexual and intimate populations which are nonrandomly distributed geographically. The populations that are sexual along the Rio Amazonas together with Rio Negro and search to function as way to obtain separately developed and commonly distributed asexual lineages, or clones. Either apomixis or automixis with main fusion and low recombination prices is inferred to end up being the cytogenetic apparatus underlying parthenogenesis in M. (more…)
