Hypodermic self-insemination as a reproductive assurance strategy. [PDF]

open access: yesProc 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 ...

Rain pollination provides reproductive assurance in a deceptive orchid. [PDF]

open access: yesAnn 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 drives transitions to self-fertilization in experimental Caenorhabditis elegans. [PDF]

open access: yesBMC 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 ...

Baker's Law Revisited: Reproductive Assurance in a Metapopulation [PDF]

open access: yesEvolution, 1998
Baker's Law states that it is more likely for self-compatible than for self-incompatible individuals to establish sexually reproducing colonies after long-distance dispersal, because only the former can do so with a single individual. This hypothesis, proposed by H. G.

The mixed mating system of a widespread weed: the case of Argemone ochroleuca Sweet (Papaveraceae)

open access: yesBotan‪ical Sciences, 2022
Background: Argemone ochroleuca is a worldwide invasive weed but is also highly valuable for their chemical compounds. Knowledge about its reproduction will help create plans for its control or its propagation. Questions: Does A.

Living in the shadows: Gastrodia orchids lack functional leaves and open flowers

open access: yesPlants, People, Planet, 2022
Non‐photosynthetic plants dependent on fungi have long fascinated botanists and mycologists. The genus Gastrodia (Orchidaceae) contains more than 100 achlorophyllous species, including some species recently discovered in Japan and Taiwan which produce ...

Evolution of Autonomous Selfing in Marginal Habitats: Spatiotemporal Variation in the Floral Traits of the Distylous Primula wannanensis

open access: yesFrontiers in Plant Science, 2021
Outcrossing plant species are more likely to exhibit autonomous selfing in marginal habitats to ensure reproduction under conditions of limited pollinator and/or mate availability.

Corolla Abscission Triggered by Nectar Robbers Positively Affects Reproduction by Enhancing Self-Pollination in Symphytum officinale (Boraginaceae)

open access: yesBiology, 2021
Nectar robbers, which affect plant fitness (directly or indirectly) in different degrees and in different ways, potentially constitute a significant part of mutualistic relationships.

Geographic variation in reproductive assurance of Clarkia pulchella [PDF]

open access: yesOecologia, 2018
Abstract Climate can affect plant populations through direct effects on physiology and fitness, and through indirect effects on their relationships with pollinating mutualists. We therefore expect that geographic variation in climate might lead to variation in plant mating systems.
