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 ...

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 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 ...

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

Biology, 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]
Oecologia, 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.

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.

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.

Assisted reproductive technology in the USA: is more regulation needed? [PDF]
, 2014 The regulation of assisted reproductive technologies is a contested area. Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA ...
