For sexual selection to act on a given sex, there must exist variation in the reproductive
success of that sex as a result of differential access to mates or fertilisations. The …

It is well known that sexual selection can target reproductive traits during successive pre‐
and post‐mating episodes of selection. A key focus of recent studies has been to understand …

Over the last decades, the field of sexual selection underwent a paradigm shift from sexual-
stereotype thinking of “eager” males and “coy” females towards a more nuanced perspective …

The operational sex ratio (OSR) has long been assumed to be a key ecological factor
determining the opportunity and direction of sexual selection. However, recent theoretical …

How do animals regenerate specialised tissues or their entire body after a traumatic injury,
how has this ability evolved and what are the genetic and cellular components underpinning …

The year 2021 marks the 150th anniversary of the publication of Charles Darwin's
extraordinary book The Descent of Man and Selection in Relation to Sex. Here, we review …

Regeneration-capable flatworms are informative research models to study the mechanisms
of stem cell regulation, regeneration, and tissue patterning. However, the lack of …

Sexual selection theory predicts a trade-off between premating (ornaments and armaments)
and postmating (testes and ejaculates) sexual traits, assuming that growing and maintaining …

Broadcast spawning invertebrates offer highly tractable models for evaluating sperm
competition, gamete-level mate choice and sexual conflict. By displaying the ancestral …

Macrostomum lignano is a free-living flatworm that is emerging as an attractive experimental
animal for research on a broad range of biological questions. One feature setting it apart …
