Sex: What is it good for? The reasons for why the vast majority of eukaryotes take a complicated detour to reproduction, when straightforward routes are available, remains a central and largely unanswered question in evolutionary biology. Reproduction can invoke clonality and different forms of meiotic parthenogenesis, self-fertilization or mating between relatives, or sexual reproduction with outcrossing. Each of these forms of reproduction directly influences the potential for adaptation and diversification of lineages and thereby the structure of biodiversity. Despite that, our understanding of the evolution of reproductive and genetic systems is still fragmentary. Even some of the most fundamental questions remain open, such as: Why is sex maintained in most species? What type of genetic changes drive transitions between different mating systems? How can mixed mating systems (involving, for example, a combination of sex and outrossing with selfing or parthenogenesis) be maintained within the same species or even within populations? What are the consequences of shifts of reproductive systems for the fate of species?
The aim of this conference is to bring together researchers working on different aspects of reproductive system evolution. We are especially interested in bringing together researchers using different approaches and different research systems in an attempt to closing the gap between theoretical and empirical research on the evolution of reproductive and genetic systems.


The conference will comprise five sessions:

  • The evolution of sexual and asexual reproduction
  • The evolution of mating systems
  • Genetic conflicts and sexual dimorphism
  • The evolution of sex determination systems
  • Open session: other aspects of reproductive systems

Application for registration
The total number of participants is limited to 115 and all participants are expected to attend for the whole duration of the conference. Selection is made on the basis of the affinity of potential participants with the topics of the conference. Scientists and PhD Students interested in the meeting should send:

- their curriculum vitae
- the list of their main publications for the 3 last years
- the abstract of their presentation:

The abstract must respect the following template:
- First line: title

- Fourth line: e-mail of the presenting author
Abstracts should be no longer than an A4 page and preferably be submitted in Times New Roman, font size 11 pts. No figures. ".doc" file format.

to the Chairperson of the conference (tanja.schwander@unil.ch) and to the secretary of the conferences (nathalie.babic@sb-roscoff.fr) before the deadline. After it, the organizers will select the participants. Except in some particular cases approved by the Chairperson, it is recommended that all selected participants present their work during the conference, either in poster form or by a brief in- session talk. The organizers choose the form in which the presentations are made. No payment will be sent with application. Information on how and when to pay will be mailed in due time to those selected.
