Dear IUFRO pathologists, Please find below and attached a call for abstracts for a technical session to be held at the IUFRO XXV World Congress meeting, September 29-October 5, 2019 in Curitiba, Brazil (http://www.iufro2019.com<http://www.iufro2019.com/> ). We also would like to draw your attention on the existence of the new IUFRO 7.03.01 Working Party "Reproductive structure insects & pathogens" ( https://www.iufro.org/science/divisions/division-7/70000/70300/70301/ ), which aims at expanding communication and co-operation among scientists and forest managers on the interactions between tree reproductive structures and both the insects and pathogens that feed and develop on them, as well as on the interactions between insects and pathogens when exploiting reproductive structures. Please feel free to contact us (see emails below) for more information and joining the mailing list of this WP. We will be happy that you circulate these informations among your own networks. Sincerely yours, Thomas, Marie-Anne & Olle CALL FOR ABSTRACT FOR A TECHNICAL SESSION FOR THE CONGRESS THEME: BIODIVERSITY, ECOSYSTEM SERVICES AND BIOLOGICAL INVASIONS TITLE OF THE SESSION : D7b - Biodiversity, biotic interactions and threats to forest ecosystem services associated with tree reproductive structure insects and pathogens in a changing world ORGANISERS Thomas Boivint1, Marie-Anne Auger-Rozenberg2 and Olle Rosenberg3 1Mediterranean Forest Research Unit, INRA, France. 2Research Unit of Forest Zoology, France. 3Skogforsk, The Forestry Reasearch Institute, Sweden. DESCRIPTION Insects and pathogens exploiting tree reproductive structures are considered the most important constraint to the reproductive success of trees during the seed pre-dispersal phase. In a context in which the effects of both climate change and biological invasions are increasingly prevalent to these species, this session will propose experimental and theoretical contributions to biodiversity, biotic interactions and threat assessment and management associated with native and exotic insects and pathogens of tree reproductive structures. DETAILS Abstracts will be accepted for both posters and oral presentations. Authors are limited to a maximum of two abstracts as presenting author. DEADLINES Abstract submission deadline: December 31, 2018. Registration and payment deadline: May 31, 2018. INSTRUCTIONS You must be registered for the event to submit an abstract, but you may pay for registration later, up to May 31. Registration and abstract submission must be completed online at http://www.iufro2019.com/ If you have questions about the session, please feel free to contact: Thomas BOIVIN thomas.boivin@inra.fr<mailto:thomas.boivin@inra.fr> Marie-Anne AUGER-ROZENBERG marie-anne.auger-rozenberg@inra.fr<mailto:marie-anne.auger-rozenberg@inra.fr> Olle ROSENBERG olle.rosenberg@skogforsk.se<mailto:olle.rosenberg@skogforsk.se> ________________________________ Thomas BOIVIN INRA Chargé de Recherche/Research scientist ________________________________ UR629 Ecologie des Forêts Méditerranéennes Equipe Biologie des Populations et Evolution INRA Centre de recherches Provence-Alpes-Côte d'Azur Domaine Saint-Paul,CS 40509 F-84914 Avignon cedex 9 Tel : (+33) 4 32 72 29 44 Web page : <https://www6.paca.inra.fr/ecologie_des_forets_mediterraneennes/Les-personnes/Personnels-permanents/BOIVIN-Thomas> https://tinyurl.com/TBoivin
