Annonaceae evolution: integrating molecules, biogeography and ecology.

This symposium aims to bring together researchers working on Annonaceae with a wide range of interests in evolution, ecology, biogeography, and molecular biology. The central objectives are: (1) to present the syntheses of broad-scale phylogenetic, biogeographical, ecological and evolutionary studies; (2) to present latest innovations in Annonaceae research with particular focus on newly emerging phylogenomic data; (3) to establish a dialogue among different research groups around the globe working in the family, and  integrate information across disciplines in order to create a framework that will allow to better understand major evolutionary patterns across the family.
Annonaceae, also known as the custard apple family, is one of the most diverse groups of early-divergent angiosperms and an important component of tropical rainforests around the world. The position of the family in the phylogeny of flowering plants in the Magnoliids make it an important study group to investigate major evolutionary transitions between early-divergent and more derived angiosperm lineages. Recent advances in Annonaceae phylogenetics allow interpreting their morphology, biogeography, and pollination biology among other disciplines in an evolutionary context. A robust phylogenetic framework has been proposed for the family. In the past ten years, studies in the family have mostly focused on: (1) Understanding its origin, biogeographical patterns and diversification mechanisms; (2) floral morphology, development and reproductive biology ; and (3) taxonomical studies.
Leading scientist working on the family will be invited to present sort talks focusing on the latest innovations and future areas of work to be developed. Starting with talks about the phylogenetics and recent classification systems, the symposium will then focus on the use of phylogenomics in order to resolve recalcitrant and important main lineages within the family. Once the phylogenetic framework has been set up sections about divergence dates, diversification rates, and biogeography will follow. Special sections on morphological evolution will deal with integrating classical morphology and functional genomics, in an attempt to promote evo-devo studies in the family. There are numerous studies on the pollination biology and eco-physiology of the Annonaceae, and experts will be invited to present the latest syntheses of these topics. It is anticipated that this symposium will not only attract the leading scientist working in the family but also will bring together early career researchers developing ideas how to apply and elaborate the existing framework to answer current questions in biogeographical and evolutionary biology.
