, salle de conférences de l'OSUR, campus de Beaulieu, UR1.Point à point - explaining patterns in Southern Hemisphere plant diversity
Richard WINKWORTH est en contrat "Attractivité Jeune chercheur" pour 3 mois.Résumé :
Identifying the origins of contemporary plant biodiversity poses many challenges but also opportunities for understanding how plants and their communities will respond to future change.
Australia, New Zealand and southern South America all have common origins in Gondwana but their subsequent histories are different. Their floras therefore represent a series of natural replicates with which to examine the ecological and evolutionary processes underlying the generation and maintenance of plant diversity.
My talk will look at our current understanding of the well-known floristic links between the austral landmasses. I will then highlight results from a recent analysis of a large multi-lineage phylogeny and discuss the implications for understanding current diversity patterns and future environmental change. I will also outline some new projects that seek to examine the place of the sub-Antarctic floras within this wider southern context.Contact
