This Special Feature of the Journal of Vegetation Science contains ten contributions from the 56th Symposium of the International Association for Vegetation Science (IAVS), which was held in Tartu, Estonia, 26–30 Jun 2013, and focused on processes underlying vegetation patterns. These contributions give an overview of recent advances in vegetation science, with topics ranging from the introduction of new methods and ideas to comprehensive analysis of vegetation patterns on a global scale. The focus of these Special Feature contributions indicates that vegetation science is becoming more global, more complex and more interdisciplinary. It is likely that progress in methods and accumulation of data have led vegetation science into a ‘new era of discovery’.
