Postcopulatory sexual selection (PCSS), comprised of sperm competition and cryptic female
choice, has emerged as a widespread evolutionary force among polyandrous animals …

More than a century ago, August Weissman defined a distinction between the germline
(responsible for propagating heritable information from generation to generation) and the …

Instances of multicellularity across the tree of life have fostered the evolution of complex
organs composed of distinct cell types that cooperate, producing emergent biological …

ABSTRACT A central paradigm in evolutionary biology is that the fundamental divergence in
the fitness interests of the sexes ('sexual conflict') can lead to both the evolution of sex …

Sperm production and allocation strategies have been a central concern of sperm
competition research for the past 50 years. But during the 'sexual cascade'there may be …

Even in well-characterized genomes, many transcripts are considered noncoding RNAs
(ncRNAs) simply due to the absence of large open reading frames (ORFs). However, it is …

Background The female reproductive tract is exposed directly to the male's ejaculate,
making it a hotspot for mating-induced responses. In Drosophila melanogaster, changes in …

The predicted temperature increase caused by climate change is a threat to biodiversity.
Across animal taxa, male reproduction is often sensitive to elevated temperatures leading to …

Declining ejaculate performance with male age is taxonomically widespread and has broad
fitness consequences. Ejaculate success requires fully functional germline (sperm) and …

Background The rapid evolution of seminal fluid proteins (SFPs) has been suggested to be
driven by adaptations to postcopulatory sexual selection (eg sperm competition). However …
