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 ...

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.

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 ...

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.

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

THE EVOLUTION OF HOMO LUDENS: SEXUAL SELECTION AND A THEOLOGY OF PLAY
Zygon, 2022 This essay argues that reflection on sexual selection can be theologically generative, and that it presents needed counteremphases to some of the discussions about theological anthropology that have been fueled by theological reflection on natural ...

PLoS Genetics, 2022 Sexual reproduction is a complex process that contributes to differences between the sexes and divergence between species. From a male's perspective, sexual selection can optimize reproductive success by acting on the variance in mating success (pre ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Objectives The association between exposure to dinutuximab beta (DB) and event‐free survival (EFS) or overall survival (OS) of neuroblastoma patients was assessed using data collected during three clinical trials (five cohorts). Methods A systematic review (March 2026) was conducted to identify relevant studies (prospective; registered DB ...
