PARTHENOGENESIS IN A FRESHWATER SNAIL: REPRODUCTIVE ASSURANCE VERSUS PARASITIC RELEASE [PDF]
Evolution; International Journal of Organic Evolution, 1992 Two alternative (but not mutually exclusive) hypotheses were contrasted for their abilities to explain the distribution of parthenogenesis in the freshwater snail Potamopyrgus antipodarum: the reproductive assurance hypothesis, which predicts that parthenogenesis will be favored in sparse populations where mates are difficult to find, and the Red Queen

Pollen Limitation and Reproductive Assurance in the Flora of the Coastal Atacama Desert
International Journal of Plant Sciences, 2010 Pollen limitation (PL) in plant populations is supposed to be particularly strong in variable pollinator environments. Here, we examined the extent of PL in the coastal Atacama Desert, where low and unpredictable rainfall drives large interannual variation in plant cover and pollinator abundances.

Pollination generalization and reproductive assurance by selfing in a tropical montane ecosystem
The Science of Nature, 2021Pollination and reproduction are important processes for understanding plant community dynamics. Information regarding pollination and reproduction is urgent for threatened ecosystems, such as tropical montane ecosystems. In tropical mountains, pollination patterns are expected to conform to the reproductive assurance theory (due to low pollinator ...

The evolution of mating‐type switching for reproductive assurance
BioEssays, 2016Alternative ways to ensure mate compatibility, such as hermaphroditism and the breakdown of self‐incompatibility, evolved repeatedly when finding a mating partner is difficult. In a variety of microorganisms where compatibility is determined by mating‐types, a highly regulated form of universal compatibility system called mating‐type switching has ...

ALLEE EFFECT AND SELF-FERTILIZATION IN HERMAPHRODITES: REPRODUCTIVE ASSURANCE IN DEMOGRAPHICALLY STABLE POPULATIONS [PDF]
Evolution; International Journal of Organic Evolution, 2004 The fact that selfing increases seed set (reproductive assurance) has often been put forward as an important selective force for the evolution of selfing. However, the role of reproductive assurance in hermaphroditic populations is far from being clear because of a lack of theoretical work.

Abstract In haploid species, sexual reproduction by selfing lacks the common benefits from recombination and is indistinguishable from asexual reproduction at the genetic level. Nevertheless, the evolution of self-compatibility, known as homothallism in organisms with mating types, has occurred hundreds of times in fungi.
