The workshop had seven key lectures by: Álvaro G. Gutiérrez (Universidad de Chile, Chile), Andrea Premoli (Universidad Nacional del Comahue, Argentina), Götz Palfner (Universidad de Concepción, Chile), Fernando Borie and Pablo Cornejo (Universidad de La Frontera, Chile), Maarja Öpik (University of Tartu, Estonia), C. Guillermo Bueno (University of Tartu, Estonia), and Jens Boy (Leibniz Universität Hannover, Germany). The key lectures covered topics such as temperate rainforest plant biodiversity (A.G. Gutiérrez and A. Premoli), EM fungal diversity patterns (G. Palfner), the effects of AM fungi on soil properties and on agriculture and bioremediation (F. Borie – P. Cornejo), molecular community ecology of AM fungi from local to global scales (M. Öpik), plant mycorrhizal traits across different scales (C.G. Bueno), and biogenic weathering by mycorrhiza (J. Boy). Overall, there were over 70 participants for this workshop, coming from eight countries (Argentina, Brazil, Chile, Estonia, Germany, Spain, United Kingdom, and Uruguay), and 26 institutions (including universities, research centers, companies, foundations and public entities). Besides the seven key lectures, 14 oral presentations and 28 posters were presented at the workshop.
