Dear all,
We are very pleased to announce our fourth online CESABINAR, which will take place on Thurs Nov 14th, 2pm, Paris time. Jos Käfer (ISEM, Montpellier) and Sylvain Glémin (ECOBIO, Rennes) will present the work of the DIVERS group: From reproductive strategies to species diversity: how does the evolution of breeding systems and associated traits shape plant species diversity?
->> Here is the group’s web page : https://www.fondationbiodiversite.fr/la-frb-en-action/programmes-et-projets/le-cesab/divers/
The aim of these CESABINARS is to present the main results of the working groups once they finish a CESAB cycle. They last about 1 hour: 40 minutes of presentation and 20 minutes of questions, perhaps a bit more. The CESABINARs are open to the whole scientific community, to the participants of the CESAB groups and to the FRB network. They are a good opportunity to see how the CESAB groups work and what are their main results, but also to get in touch with the CESAB community and to get informed about our news. They are in English, so don’t hesitate to promote them in your networks.

In case you miss it, this session (and all the other ones whenever possible) will be recorded and shared on the FRB’s youtube channel.
Presentation abstract:
« Angiosperms (flowering plants) present an exceptional diversity of breeding systems, with variation both in gender distribution within and among individuals (from hermaphroditism to separate sexes) and in mating patterns (from strict outcrossing to predominant selfing). Breeding systems affect species diversification and are linked to other life-history and ecological traits, which themselves also affect diversification. The leading question in the DIVERS project is how these traits interact to give rise to the current plant biodiversity patterns.
We first reviewed the mechanisms underlying the effects of traits on the components of diversification, speciation and extinction. Next, we reviewed the macroevolutionary evidence for these effects. Both reviews reveal a range of contrasting patterns and trends, which point to the importance of the ecological and evolutionary context of each species. We then characterized the reproductive strategies of flowering plants by studying how traits co-occur in a representative sample of the flowering plant diversity. This clearly demonstrates that reproductive, i.e. floral and pollination-related traits, capture a large part of trait variation, almost independent of vegetative traits. We discuss how such trait combinations can be used to better understand evolutionary and ecological diversity patterns. »
