DOI: 10.1002/jmor.21572
Abstract: The penis bone, or baculum, is present in many orders of mammals, although its function is still relatively unknown, mainly due to the challenges with studying the baculum in vivo. Suggested functions include increasing vaginal… read more here.

Sex peptide receptor-regulated polyandry modulates the balance of pre- and post-copulatory sexual selection in Drosophila

DOI: 10.1038/s41467-018-08113-w
Abstract: Polyandry prolongs sexual selection on males by forcing ejaculates to compete for fertilisation. Recent theory predicts that increasing polyandry may weaken pre-copulatory sexual selection on males and increase the relative importance of post-copulatory sexual selection,… read more here.

Resource-dependent investment in male sexual traits in a viviparous fish

DOI: 10.1093/beheco/arac060
Abstract: Abstract Exaggerated and conspicuous sexually selected traits are often costly to produce and maintain. Costly traits are expected to show resource-dependent expression, since limited resources prevent animals from investing maximally in multiple traits simultaneously. However,… read more here.

Female-limited X-chromosome evolution effects on male pre- and post-copulatory success

DOI: 10.1098/rsbl.2020.0915
Abstract: Intralocus sexual conflict arises when the expression of shared alleles at a single locus generates opposite fitness effects in each sex (i.e. sexually antagonistic alleles), preventing each sex from reaching its sex-specific optimum. Despite its… read more here.

Positive correlations between pre‐ and post‐copulatory sexual traits in warblers

DOI: 10.1111/jav.01694
Abstract: Theoretical models predict that investment in pre‐copulatory and post‐copulatory sexually selected traits should trade‐off. At the macroevolutionary scale, the majority of studies to date have focused on male weaponry as the target of pre‐copulatory sexual… read more here.

Pre‐ and post‐copulatory sexual selection increase offspring quality but impose survival costs to female field crickets

DOI: 10.1111/jeb.14132
Abstract: Whether sexual selection increases or decreases fitness is under ongoing debate. Sexual selection operates before and after mating. Yet, the effects of each episode of selection on individual reproductive success remain largely unexplored. We ask… read more here.

DOI: 10.1371/journal.pone.0261894
Abstract: Pathogens exert a profound and pervasive cost on various aspects of primate sociality and reproduction. In olive baboons (Papio anubis) at Lake Manyara National Park, Tanzania, genital skin ulcers, caused by the bacterium Treponema pallidum… read more here.
