Sexual selection in a simultaneous hermaphrodite : mate choice and sperm utilization patterns [PDF]
, 2011 Sexual selection processes, in general, are distinguished in precopulatory and postcopulatory mechanisms. In the animal kingdom, precopulatory mechanisms are related to mate competition and mate choice before the copulation.

Sexual selection, germline mutation rate and sperm competition
BMC Evolutionary Biology, 2003 Background An important component of sexual selection arises because females obtain viability benefits for their offspring from their mate choice.

Adaptation to a bacterial pathogen in Drosophila melanogaster is not aided by sexual selection
Ecology and Evolution, 2022 Theory predicts that sexual selection should aid adaptation to novel environments, but empirical support for this idea is limited. Pathogens are a major driver of host evolution and, unlike abiotic selection pressures, undergo epidemiological and co ...

Divergent natural selection alters male sperm competition success in Drosophila melanogaster
Ecology and Evolution, 2022 Sexually selected traits may also be subject to non‐sexual selection. If optimal trait values depend on environmental conditions, then “narrow sense” (i.e., non‐sexual) natural selection can lead to local adaptation, with fitness in a certain environment

Can Sexual Selection Drive the Evolution of Sperm Cell Structure?
Cells, 2021 Sperm cells have undergone an extraordinarily divergent evolution among metazoan animals. Parker recognized that because female animals frequently mate with more than one male, sexual selection would continue after mating and impose strong selection on ...

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps
, 2014 Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Sexual selection gradients change over time in a simultaneous hermaphrodite
eLife, 2017 Sexual selection is generally predicted to act more strongly on males than on females. The Darwin-Bateman paradigm predicts that this should also hold for hermaphrodites.

Resource acquisition and pre‐copulatory sexual selection
Ecology and Evolution, 2022 Sexual selection influences the evolution of phenotypic traits and contributes to patterns of biodiversity. In many animals, mating involves sequential steps.

Symmetry Is Related to Sexual Dimorphism in Faces: Data Across Culture and Species [PDF]
, 2008 Summary Background Many animals both display and assess multiple signals. Two prominently studied traits are symmetry and sexual dimorphism, which, for many animals, are proposed cues to heritable fitness benefits.
