We are delighted to announce that the 2025 New Phytologist Tansley Medal for excellence in plant science has been awarded to Camille S. Delavaux.
Camille is a Senior Researcher at the Netherlands Institute of Ecology (NIOO-KNAW). The focus of her work is plant–mutualist interactions and their consequences for biogeography, diversity and invasion in a changing world.
Camille's Tansley insight reviews the evidence for how biotic mutualisms shape plant biogeography, the consequences for ecology, evolution and invasion, and provides a synthesis of mechanisms underpinning the mutualist filter:
We also congratulate six outstanding Tansley Medal runners up:
Juan Alonso-Serra, Academy Research Fellow, Faculty of Biological and Environmental Sciences, University of Helsinki, Finland. Tansley insight: ‘On growth and flow: hydraulics of above ground meristems’.
Antoine Cabon, Postdoctoral SNF Fellow, Swiss Federal Institute for Forest, Snow and Landscape Research WSL, Birmensdorf, Switzerland. Tansley insight: ‘Distal to proximal: a continuum of drivers shaping tree growth and carbon partitioning’.
Andrew F. Feldman, Associate Research Scientist, NASA Goddard Space Flight Center and University of Maryland Earth System Science Interdisciplinary Center, USA. Tansley insight: ‘The pulse of global vegetation: do individual rainfall events create a lasting imprint on photosynthesis?’
Julia M. Kreiner, Assistant Professor, Department of Ecology & Evolution, University of Chicago, USA. Tansley insight: ‘The genetic architecture and dynamics of adaptation across changing landscapes’.
Julian Schrader, University Lecturer. School of Natural Sciences, Macquarie University, Sydney, Australia. Tansley insight: ‘Trait-based island biogeography as a tool for studying future ecological communities’.
Zhongshou Wu, Principal Investigator, State Key Laboratory of Rice Biology and Breeding, Institute of Biotechnology, and the Laboratory of Molecular Biology of Crop Pathogens and Insects, Zhejiang University, Hangzhou, China. Tansley insight: ‘TIR innovations in plant immunity’.
We offer our warmest congratulations to Camille and her fellow runners up, and we wish them continued success in their future careers.
The judging panel for the 2025 Tansley Medal was comprised of the following New Phytologist Editors: Amy T. Austin (Buenos Aires, Argentina), Ian A. Dickie (Canterbury, New Zealand), Liam Dolan (Vienna, Austria), Elena M. Kramer (Cambridge, MA, USA) and Shuhua Yang (Beijing, China).
The New Phytologist Tansley Medal for excellence in plant science is awarded annually in recognition of outstanding contributions to research by individuals in the early stages of their career. Applications for the 2026 New Phytologist Tansley Medal have closed, but you can be the first to know when applications for the 2027 New Phytologist Tansley Medal open by signing up to our mailing list.
Supporting early career scientists
The New Phytologist Foundation supports early career plant scientists, through a number of initiatives including the annual Tansley Medal competition and the New Phytologist next generation scientists symposium. New Phytologist next generation scientists 2026 will be held in Pune, India, in December 2026. Applications to attend will open in spring 2026.
The New Phytologist Foundation is a not-for-profit organisation committed to the advancement and dissemination of knowledge and research in plant science. The Foundation currently fulfils this objective by publishing the scholarly journals New Phytologist and Plants, People, Planet and by funding a wide range of activities, such as the international New Phytologist Symposia and Workshop series, awarding grants, and the sponsorship of awards such as the Tansley Medal, named after New Phytologist’s founder Sir Arthur Tansley.
