Reproductive Assurance and the Evolution of Pollination Specialization [PDF]
International Journal of Plant Sciences, 2007 (Uploaded by Plazi for the Bat Literature Project) Flowers with highly specialized pollination systems sometimes have the ability to self-pollinate, contradicting our notion that pollination specialization reflects selective pressures to ensure high maternal outcrossing rates.

Royal Society Open Science, 2023 To understand mating-system evolution in self-compatible hermaphrodites, variation in selfing rates is highly relevant. Empirical studies are rarely designed to capture variation between individuals, instead often comparing species and populations.

Male age mediates reproductive investment and response to paternity assurance [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2013 Theory predicts that male response to reduced paternity will depend on male state and interactions between the sexes. If there is little chance of reproducing again, then males should invest heavily in current offspring, regardless of their share in paternity.

, 2023 It is generally considered that sexual organisms show faster evolutionary adaptation than asexual organisms because sexuals can accumulate adaptive mutations through recombination.

The Rise of Apomixis in Natural Plant Populations
Frontiers in Plant Science, 2019 Apomixis, the asexual reproduction via seed, has many potential applications for plant breeding by maintaining desirable genotypes over generations.

Partial selfing, ecological disturbance and reproductive assurance in an invasive freshwater snail [PDF]
Heredity, 2005 Although reproductive assurance (RA) might play a central role in the evolution of the selfing rate, this hypothesis has never been seriously investigated in an hermaphroditic animal. We studied the mating system of the freshwater snail Physa acuta in which the availability of mating partners might be highly variable, because this species is an ...

Going solo: discovery of the first parthenogenetic gordiid (Nematomorpha: Gordiida). [PDF]
PLoS ONE, 2012 Despite the severe fitness costs associated with sexual reproduction, its persistence and pervasiveness among multicellular organisms testifies to its intrinsic, short-term advantages.

F1000Research, 2014 The reproductive assurance hypothesis states that self-incompatible female plants must produce twice the number of seeds relative to their self-compatible hermaphroditic counterparts to persist in gynodioecious populations.

Mixed Mating System Are Regulated by Fecundity in Shorea curtisii (Dipterocarpaceae) as Revealed by Comparison under Different Pollen Limited Conditions. [PDF]
PLoS ONE, 2015 The maintenance of mixed mating was studied in Shorea curtisii, a dominant and widely distributed dipterocarp species in Southeast Asia. Paternity and hierarchical Bayesian analyses were used to estimate the parameters of pollen dispersal kernel, male ...
