Anke Stein worked in the Ecology group up to December 2017 to study the distribution of naturalized alien plant species worldwide. In particular, she focused on whether plant invasion and naturalization lead to a taxonomic and phylogenetic homogenization of the global flora. 

Emily Haeuser did a PhD research project on experimental and modeling approaches to attempt to identify Europe’s next likely invaders under future climatic conditions from among a large pool of previously-introduced, frequently-planted ornamental alien species which may be better suited to future rather than current European climates. She completed her PhD in December 2017.

Samuel Carleial did a research project on the plant model species Arabidopsis lyrata and its reproductive system and completed his PhD in July 2017.

Elisabeth Rehn was Mark's personal assistant until February 2017. Now she has time enough for a somewhat peculiar hobby.

Gregor Müller started to do his PhD-research in March 2013 on "Testing the relative roles of competition and plant soil feedback in explaining commonness and rarity of alien and native plant species".

Marti March Salas has visited our group from September to December 2016.

Katharina Mayer was engaged in a project on climate change around the Lake of Constance for which she did research from 2014 to 2016.

Arne Erpenbach PhD worked in our group from May to October 2016. As a specialist in R and Access he worked with the GloNAF database.

Wayne Dawson PhD was in the group from March 2011 to December 2015. His topic is plant-soil interaction. He is in Durham now.

Yanhao Feng started as a PhD-student in Konstanz in 2011 funded by the China Scholarship Council. His PhD-thesis "Regional- and Local-scale Drivers of Establishment and Invasion Success of Alien Plants" was published in 2015.

Lei Ning was in Konstanz from 2013 to 2015 as a joint PhD-student (Prof. Dr. Fei-Hai Yu, Beijing Forestry University. His topic is "The role of allelopathic effects in plant invasions".

Ayub Oduor was examining the roles of below-ground insect herbivores in invasion success of plants. His focus was on two topics 1. damage by below-ground insect herbivores will cause invasive populations to express a higher level of tolerance than native populations of the same species. 2. Damage by below-ground insect herbivores will cause invasive populations to have higher competitive abilities than native populations of the same species. He was funded by a Georg-Forster-Scholarship.

Janosch Sedlacek studied the heritability of plant traits, natural selection in different habitats, and the potential evolutionary responses of Salix herbacea to climate change. His research was part of the SNF research project "Growth limitations, phenotypic plasticity and micro-evolution in a long-lived alpine shrub".

Lidewij Keser spent some years (2011-2014) in our group as a guest student from Bern. She investigated various aspects of clonality and its contribution to plant species invasiveness.

Lena Horstmeyer did her MSci-Thesis "Survival and growth of common and rare alien and native plants: The role of soil fungi and disturbance" in our group in 2014.

Marcel Dorken has spent several months in our group in 2014 funded by the Humboldt-Foundation.

Margherita Gioria has been a member of our group for several months and promised to keep in close contact.

Jens Joschinski did his MSci-Thesis "Do selfers differ from outcrossers in growth and resistance to caterpillars" in our group.

Demissew Tsigemelak (MSci, University of Nairobi, Kenia) was supported by DAAD to spend the summer 2012 in order to learn something about ecology in Konstanz.

Sina Glöckner did her MSci-Thesis on "Breaking open the black box of soil: Identifying shifts in soil microbial communities in plant-soil feedback experiments."

Stefanie Lemmermeyer did her MSci-Thesis on "The role of microbial soil communities in plant-soil feedback of fast and slow growing plant species."
