Free-living flatworms of the genus Macrostomum are small and transparent animals,
representing attractive study organisms for a broad range of topics in evolutionary …

Whole genome duplication (WGD) is an evolutionary event resulting in a redundancy of
genetic material. Different mechanisms of WGD, allo-or autopolyploidization, lead to distinct …

The free-living, simultaneously hermaphroditic flatworms of the genus Macrostomum are
increasingly used as model systems in various contexts. In particular, Macrostomum lignano …

Background Sex allocation is the distribution of resources to male or female reproduction. In
hermaphrodites, this concerns an individual's resource allocation to, for example, the …

In species with multiple mating, intense sexual selection may occur both before and after
copulation. However, comparing the strength of pre-and postcopulatory selection is …

The evolution of gonochorism from hermaphroditism is linked with the formation of sex
chromosomes, as well as the evolution of sex-biased and sex-specific gene expression to …

Sperm competition is a potent mechanism of postcopulatory sexual selection that has been
found to shape reproductive morphologies and behaviours in promiscuous animals …

Nuclear receptors (NRs), a series of key transcription factors that are mostly activated by
endogenous ligands or environmental xenobiotics, are reportedly good phylogenetic …

B chromosomes (Bs) or supernumerary chromosomes are extra chromosomes in the
species karyotype that can vary in its copy number. Bs are widespread in eukaryotes …

Sexual selection drives the evolution of many striking behaviors and morphologies and
should leave signatures of selection at loci underlying these phenotypes. However, although …
