    Population genetics of fungal diseases of plants by Giraud T., Enjalbert J., Fournier E., Delmotte F., Dutech C.

    Published 2008-09-01
    “…Yet, the advent of molecular markers offers great tools for studying important processes, such as dispersal, mating systems, adaptation to host and speciation. Here we highlight some studies that used molecular markers to address questions about the population genetics of fungal (including oomycetes) plant pathogens. …”

    Developments of the Price equation and natural selection under uncertainty. by Grafen, A

    Published 2000
    “…Population genetics theory makes clear that predicting gene frequency changes requires more detailed knowledge, for example of linkage and linkage disequilibrium and mating systems. Because gene frequency changes underlie adaptation, this can lead to a suspicion that approaches ignoring these sophistications are approximate or tentative or wrong. …”

    Published 2007
    “…Sperm storage is a widespread phenomenon across taxa and mating systems but its consequences for central fitness parameters, such as sex ratios, has rarely been investigated. …”

    Sex differences in intimate relationships by Palchykov, V, Kaski, K, Kertész, J, Barabási, A, Dunbar, R

    Published 2012
    “…Evolutionary theory suggests that, even in monogamous mating systems, the pattern of investment in close relationships should vary across the lifespan when post-weaning investment plays an important role in maximising fitness. …”

    Sexual selection in females and the evolution of polyandry by Salomé Fromonteil, Lucas Marie-Orleach, Lennart Winkler, Tim Janicke

    Published 2023-01-01
    “…Our findings offer support for the idea that sexual selection is widespread in females and to play a key role for the evolution of animal mating systems. Thereby, our results extend our understanding of the evolutionary consequences of sexual reproduction and contribute to a more balanced view of how sexual selection operates in males and females.…”

    Sexual ratio in populations of Sparisoma radians and Sparisoma atomarium at Los Roques Archipelago, Venezuela: An evolutionary approach by JR De-Nóbrega, E Villamizar

    Published 2004-03-01
    “…The differences observed between species agree with that reported in another study, which outlines an evolutionary explanation based on the different mating systems of these species. Significant differences were detected in the form and central localization of size distribution between the two samples of S. radians, accompanied with a displacement in the respective size class for sex change and the constancy in overall sex ratio. …”

    Extra-pair paternity in a Neotropical rainforest songbird, the White-necked Thrush Turdus albicollis (Aves: Turdidae) by Carlos Biagolini-Jr, Mariellen C. Costa, Daniel F. Perrella, Paulo V.Q. Zima, Lais Ribeiro-Silva, Mercival R. Francisco

    “…ABSTRACT Over the last two decades, several studies have shown that the mating systems of various birds are more complex than previously believed, and paternity tests performed with molecular techniques have proved, for instance, that the commonly observed social monogamy often presents important variations, such as extra-pair paternity. …”

    Sexually selected traits predict patterns of species richness in a diverse clade of suboscine birds. by Seddon, N, Merrill, R, Tobias, J

    Published 2008
    “…However, the explanatory power of previous models may have been constrained because they employed coarse-scale, between-family comparisons and used mating systems and morphological cues as surrogates for sexual selection. …”

    Sexually transmitted disease in birds: occurrence and evolutionary significance. by Sheldon, B

    You are what your mother eats: evidence for maternal preconception diet influencing foetal sex in humans. by Mathews, F, Johnson, P, Neil, H

    Published 2008
    “…In mammals, the search for consistent patterns is complicated by variations in mating systems, social hierarchies and litter sizes. Humans have low fecundity, high maternal investment and a potentially high differential between the numbers of offspring produced by sons and daughters: these conditions should favour the evolution of facultative sex ratio variation. …”

    Brain and behaviour in primate evolution by Dunbar, R

    Published 2010
    “…While the standard form of the social brain hypothesis in primates is a quantitative relationship between social group size and brain size, comparative analyses for other mammal and bird taxa reveal that it takes a purely qualitative (i.e., categorical) form in all nonprimates examined so far: species with pairbonded (i.e., monogamous) mating systems have larger brains than all others. I suggest that this difference is due to the fact that anthropoid primates developed bonded social systems early in their evolutionary history. …”
