The organising committee welcomes you to the 45th New Phytologist symposium on Ecological and evolutionary consequences of plant–fungal invasions. 

Marc-André Selosse welcomes delegates on behalf of the Editors of New Phytologist and Plants, People, Planet and the New Phytologist Foundation. 

Editors in attendance include: Marc-André Selosse, Amy Zanne, Ian Dickie, Maarja Öpik and Tara Hudiburg.  

In this session, we'll explore the ways in which plants or fungi may influence ecosystem functions such as productivity, carbon storage, and nutrient cycling, upon plant and/or fungal invasion into novel environments. Submitted abstracts should explore connections between ecosystems and invasive plants and/or fungi.

More details to be confirmed

Introductions are often associated with novel selection pressures, as well as demographic processes that may lead to evolution through genetic drift. Submitted abstracts should explore some aspect of genetics or evolution in the context of invasion by plants and/or fungi.

Details to be announced

Despite their global use, we know little about effect of fungal biofertilizers in ecosystems. Can inoculated fungi become invasive? How do they affect ecosystems? Are they an effective tool for growers? Talks should specifically address deliberate introduction of fungal biofertilizers.

Part 1 will cover effects aboveground
