Organisms evolve in response to their natural environment. Consideration of natural
ecological parameters are thus of key importance for our understanding of an organism's …

As fundamental features of nearly all animal species, sexual dimorphisms and sex
differences have particular relevance for the development and function of the nervous …

Background Evolutionary transitions from outcrossing between individuals to selfing are
partly responsible for the great diversity of animal and plant reproduction systems. The …

Competition among sperm to fertilize oocytes is a ubiquitous feature of sexual reproduction
as well as a profoundly important aspect of sexual selection. However, little is known about …

Basic models of mating-system evolution predict that hermaphroditic organisms should
mostly either cross-fertilize, or self-fertilize, due to self-reinforcing coevolution of inbreeding …

Partial selfing, whereby self-and cross-fertilization occur in populations at intermediate
frequencies, is generally thought to be evolutionarily unstable. Yet, it is found in natural …

We provide a partial test of the mitonuclear sex hypothesis with the first controlled study of
how male frequencies and rates of outcrossing evolve in response to mitonuclear mismatch …

Hermaphroditic organisms are key models in sex allocation research, yet the developmental
processes by which hermaphrodite sex allocation can evolve remain largely unknown. Here …

Whether or not genetic divergence in the short-term of tens to hundreds of generations is
compatible with phenotypic stasis remains a relatively unexplored problem. We evolved …

Hosts exhibit a variety of defence mechanisms against parasites, including avoidance. Both
host–parasite coevolutionary dynamics and the host mating system can alter the …
