Factors influencing paternity in multiply mated female red-sided garter snakes and the persistent use of sperm stored over winter
- BiologyBehavioral Ecology and Sociobiology
- 2014
Female influence over sperm and/or copulatory plug transfer during matings may also affect which male fathers her offspring in response to coercive matings as the authors assisted females to mate for their second mating.
Directional postcopulatory sexual selection is associated with female sperm storage in Trinidadian guppies
- BiologyEvolution; international journal of organic evolution

Results indicate that processes associated with FSS tend to reinforce the strength of PCSS in guppies, rather than weaken it, and it is necessary to test whether this pattern changes in case of more prolonged FSS.
Sexual coloration and sperm performance in the Australian painted dragon lizard, Ctenophorus pictus
- BiologyJournal of evolutionary biology
- 2017
It is shown that male painted dragons use this bright yellow bib as both an inter‐ and intrasexual signal, and it is suggested that the bib polymorphism may be maintained by complex interactions between physiological or life‐history traits including other sperm or ejaculate traits and environmental influences.
Sperm storage and sperm competition across ovarian cycles in the dragon lizard, Ctenophorus fordi.
- BiologyJournal of experimental zoology. Part A, Ecological genetics and physiology
- 2013
It is suggested that sperm storage across ovarian cycles may be common in small, multi-clutched lizards and that its impact on selection on male phenotypes could contribute to the evolution of lizard mating systems.
Sperm competition and the evolution of alternative reproductive tactics in the swordtail Xiphophorus nigrensis (Poeciliidae)
- Biology
- 2011
This study suggests that the evolution of sperm quantity and quality can be decoupled and that sperm morphology is likely to play an important role in mediating sperm competition through its effects on sperm performance.

DURATION OF SPERM STORAGE IN THE SIMULTANEOUS HERMAPHRODITE LYMNAEA STAGNALIS
- Biology

This study investigated the pattern of outcrossing over time after a single mating in a freshwater snail, Lymnaea stagnalis, using a microsatellite marker and reveals that overall body size is positively correlated with paternity longevity.
Male alternative reproductive tactics and sperm competition: a meta-analysis.
- BiologyBiological reviews of the Cambridge Philosophical Society

There is little evidence that male ARTs differ substantially in investment into sperm and ejaculates across species, and studies often use sperm or ejaculate traits that do not reflect overall post-mating investment accurately or affect fertilisation success.
Genital morphology associated with mating strategy in the polymorphic lizard, Uta stansburiana

It is suggested that strong sexual selection may drive genital trait differentiation across morphs within populations of terrestrial vertebrates.
Viability, behavior, and color expression in the offspring of matings between common wall lizard Podarcis muralis color morphs
- BiologyCurrent zoology
- 2022
It is concluded that inter-morph breeding remains entirely viable and genetic incompatibilities are of little significance for the maintenance of discrete color morphs in P. muralis from the Pyrenees.

Mating system variation and morph fluctuations in a polymorphic lizard
- BiologyMolecular ecology
- 2007
It is shown using microsatellites that the frequency of mixed paternity in the wild is low, that all morphs on average have the same number of offspring sired per year, and that mating system variation (polyandry vs. monandry) is strongly correlated with perch density on male territories.
Sons are made from old stores: sperm storage effects on sex ratio in a lizard
- BiologyBiology Letters
- 2007
It is shown that stored sperm have a 23% higher probability of producing sons than daughters, which means shifts in sex ratio, for example over the reproductive season, can partly be explained by different survival of son-producing sperm or some unidentified female mechanism taking effect during prolonged storage.

The results suggest that males may prolong copulation to become more competitive when under increased risk of sperm competition.

Using nuclear microsatellites to estimate the paternity rates of three male lizard strategies previously modeled as a rock-paper-scissors game, yellow-throated sneaker males sire offspring via secretive copulations and often share paternity of offspring within a female's clutch, indicating that sperm competition may be an important component of their strategy.
Why do female adders copulate so frequently?

These field studies on Swedish adders provide the first empirical evidence that multiple copulations, with different partners each time, increase offspring viability.
Multiple paternity in reptiles: patterns and processes
- BiologyMolecular ecology
- 2008
It is argued that the most parsimonious explanation for patterns of multiple paternity is that it represents the combined effect of mate‐encounter frequency and conflict over mating rates between males and females driven by large male benefits and relatively small female costs, with only weak selection via indirect benefits.

A rare female-like morph of ruffs is described: the ‘missing’ third alternative mating strategy, which is called ‘faeder’ and appears to combine feminine and masculine behaviours.
