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:

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.
