Repeated evolution of self-compatibility for reproductive assurance [PDF]
Nature Communications, 2018 Mating-type switching enables self-compatible reproduction in fungi, but switching ability is variable even within species. Here, the authors find de novo evolution of switching genotypes in experimentally evolved fission yeast populations and show a ...

Diplostigmaty in plants: a novel mechanism that provides reproductive assurance [PDF]
Biology Letters, 2013 Differentiation of female sexual organs in flowering plants is rare and contrasts with the wide range of male reproductive strategies. An unusual example involves diplostigmaty, the possession of spatially and temporally distinct stigmas inSebaea(Gentianaceae).

Hypodermic self-insemination as a reproductive assurance strategy. [PDF]
Proc Biol Sci, 2015 Self-fertilization occurs in a broad range of hermaphroditic plants and animals, and is often thought to evolve as a reproductive assurance strategy under ecological conditions that disfavour or prevent outcrossing. Nevertheless, selfing ability is far from ubiquitous among hermaphrodites, and may be constrained in taxa where the male and female ...

Reproductive assurance drives transitions to self-fertilization in experimental Caenorhabditis elegans. [PDF]
BMC Biol, 2014 Evolutionary transitions from outcrossing between individuals to selfing are partly responsible for the great diversity of animal and plant reproduction systems. The hypothesis of 'reproductive assurance' suggests that transitions to selfing occur because selfers that are able to reproduce on their own ensure the persistence of populations in ...

Rain pollination provides reproductive assurance in a deceptive orchid. [PDF]
Ann Bot, 2012 Abiotic pollination by wind or water is well established in flowering plants. In some species pollination by rain splashes, a condition known as ombrophily, has been proposed as a floral strategy. However, evidence for this type of abiotic pollination has remained controversial and many reported cases have subsequently been shown to be false.

Reproductive Assurance Maintains Red-Flowered Plants of Lysimachia arvensis in Mediterranean Populations Despite Inbreeding Depression [PDF]
Frontiers in Plant Science, 2020 Flower color polymorphism, an infrequent but phylogenetically widespread condition in plants, is captivating because it can only be maintained under a few selective regimes but also because it can drive intra-morph assortative mating and promote ...

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

Comparison status and factors of pregnancy stress among pregnant women with second child between advanced maternal age and reproductive age: a cross-sectional study [PDF]
BMC Pregnancy and ChildbirthBackground With the implementation of China’s two-child policy and the rising trend of advanced maternal age, pregnancy stress in women with a second child has become a significant concern.

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.

18-Year Monitoring of the Steno-Endemic Verbascum rupicola (Scrophulariaceae): Compounding Pressures and the Extinction Vortex [PDF]
PlantsThe steno-endemic Verbascum rupicola faces a precarious future due to its extreme habitat specialization on tectonically active hydrothermal quartz veins. This study presents a long-term assessment based on periodic population censuses spanning 18 years (
