Description du projet
Un regard plus approfondi sur la conservation des orchidées en Méditerranée
Les orchidées font partie des groupes de végétaux les plus menacés par le changement climatique. Elles ont toutefois développé des associations symbiotiques avec les champignons du sol afin de se reproduire à partir de graines. Le projet FORECAST, financé par l’UE, mènera une étude complète des relations symbiotiques entre les orchidées araignées, un groupe qui suscite de vives inquiétudes en matière de conservation dans les habitats méditerranéens d’Australie, et leurs partenaires fongiques. Le projet combinera des expériences moléculaires, empiriques et physiologiques, afin de proposer un système modèle permettant de prédire la réponse des orchidées au changement climatique et la résilience de ces symbioses dans des environnements détériorés et naturels. FORECAST élaborera de nouvelles stratégies de conservation continue des orchidées dans les environnements méditerranéens.
Objectif
Compounded by habitat fragmentation and the pervasive impact of climate change, biodiversity, particularly in global biodiversity hotspots, faces an uncertain future. Orchids, among the most threatened plant groups in the world, have symbiotic associations with soil fungi in order to establish new individuals from seeds. Yet this important interaction between orchids and fungi is poorly understood in the context of rapid environmental change. The FORECAST project will provide a detailed investigation into the symbiotic relationship between a high profile orchid group of high conservation concern in Mediterranean habitats in Australia, the spider orchids, (genus Caladenia) and their fungal associates, using a combination of molecular, field, and physiological experiments. This will be used as a model system to predict the response of orchids to ongoing climate change and the resilience of these fungal symbioses in degraded and natural environments. Subsequently, during the incoming phase, the project will transfer the skills and perspectives learned from the outgoing phase and focus on members of European orchid Anacamptis in the Mediterranean. The fellowship will be hosted by Prof. Michael F. Fay at the Royal Botanic Gardens, Kew with a two year outgoing period at the Curtin University of Western Australia under the supervision of Prof. Kingsley W. Dixon, one of the world’s leading experts in the field of orchid ecology and conservation. I will learn state-of-the-art techniques for the study of orchid mycorrhizal fungi in Australia and transfer them to one of world’s leading botanic gardens and conservation centres, RBG Kew. This work will be facilitated by ongoing collaborations with the University of Naples Federico II. The ultimate goal of the FORECAST project is to develop new multi-faceted strategies for ongoing orchid conservation in Mediterranean habitats under climate change, thereby uniting conservation approaches in both Australia and Europe.
