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

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 ...

Genetic cost of reproductive assurance in a self-fertilizing plant
Nature, 2002The transition from outcrossing to self-fertilization is one of the most common evolutionary trends in plants. Reproductive assurance, where self-fertilization ensures seed production when pollinators and/or potential mates are scarce, is the most long-standing and most widely accepted explanation for the evolution of selfing, but there have been few ...
