The ability to adapt to marginal habitats, in which survival and reproduction are initially poor,
plays a crucial role in the evolution of ecological niches and species ranges. Adaptation to …

Though polyploidy is an important aspect of the evolutionary genetics of both plants and
animals, the development of population genetic theory of polyploids has seriously lagged …

Asexual organisms usually have larger and more northern distributions than their sexual
relatives. This phenomenon, called geographical parthenogenesis, has been controversially …

Apomixis, the asexual production of seed, is a trait estimated to occur in fewer than 1% of
flowering plant species, with an uneven distribution among lineages. In the past decade …

Theory predicts that sexual reproduction is difficult to maintain if asexuality is an option, yet
sex is very common. To understand why, it is important to pay attention to repeatably …

Genetic exchange enables parasites to rapidly transform disease phenotypes and exploit
new host populations. Trypanosoma cruzi, the parasitic agent of Chagas disease and a …

Plants produce large amounts of secondary metabolites in their shoots and roots and store
them in specialized secretory structures. Although secondary metabolites and their secretory …

The Asteraceae is commonly listed, along with Poaceae and Rosaceae, as one of the
principal families within which asexual reproduction by seed, ie, apomixis, is prolific. A …

Apomixis, the asexual reproduction via seed, has long been regarded a blind alley of
evolution. This hypothesis was based on the assumption that apomixis is an irreversible …

Asexual organisms often occupy larger and more northern distribution areas than their
sexual relatives. These phenomena, summarized under the term “geographical …
