Species spread in a warmer and globalized world

October 18, 2017 - October 20, 2017

Hôtel Dupanloup
1 rue Dupanloup
45000 Orléans


The world is experiencing several global changes interacting one with each other and affecting species distribution. In the last decades climate change has modified species distribution, bringing native species to expand or retract their range, and facilitating the establishment of alien species and biological invasions.

Globalization is increasing the risk of inter-continental transportation and introduction of alien species. Trade intensification can bring into contact different lineages of the expanding species coming from distant areas of the original distribution range, thus increasing their genetic variability and modifying their adaptive potential.

This process is also enhanced by anthropization of the landscape. In this context, ornamental plant trade plays a key role in pests and diseases spread. International plant trade is one of the main sources of biological invasions favoring the establishment of alien species and the spread of both native and invasive species. Moreover, ornamental trees are an increasing component of urban and suburban landscape and thus represent one of the main routes for the spreading of invasive insects and pathogens in new areas.

This international conference will foster discussion about the different aspects of climate-driven expansions and biological invasions, bringing together researchers with diverse scientific backgrounds ranging from population genetics to ecology.

Main Topics

The conference will cover topics on global changes and insect pest and disease introduction, establishment or spread in relation with: Climate change ; Global trade with a special focus on ornamental plant trade ; Landscape structure and land use changes ; Genetic markers for tracking species ; Genomics of adaptation to new environments ; Modeling of species spread ; Management of native or alien expanding species

Hôtel Dupanloup : 1, rue Dupanloup - 45000 ORLEANS - FR

The conference venue is unique. Located right next to the Orléans’ cathedral, the episcopal palace of Orléans, built between 1635 and 1641, locally known as the Hôtel Dupanloup, is a classical French building which served until 1905 of residence to the bishops of Orléans.  Since 2014, the renewed palace hosts the International University Center for Research and Le Studium Loire Valley Institute for Advanced Studies.

Participants will be welcomed in this exceptional surrounding, blending Middle Age and Renaissance cultures with modern design and will have the opportunity to discover French cuisine and wines.


The submission of abstract for a talk is closed.

Please send your poster (or the abstract of your poster) to maurine.villiers@lestudium-ias.fr before the 02/10/2017. Please note that we do not print the posters, but racks & pins will be provided for up to A0 sizes. 

Following the conference, participants will be encouraged to submit a paper to a special issue of Les Annales de la Société Entomologique de France on insect expansion (deadline: December 20th, 2017).
