The 1918 doctoral thesis titled On Plants Suited to a Cold and Short Summer established Thekla Resvoll as a pioneer in plant population ecology. By meticulously observing the perennation and propagation methods of alpine species, she developed an analytical framework for understanding how flora adapted to extreme environments long before the discipline was formally defined.
Academic Foundation and Early Career
Born in Vågå in 1871, Thekla Susanne Ragnhild Resvoll began her academic path after working as a nurse in Stockholm. In 1894, she started her natural history studies at the Royal Frederick University, now the University of Oslo. She refined her research skills under Axel Blytt, later moving to the University of Copenhagen to work in the botanical laboratory led by Eugen Warming. By 1902, she secured an associate professor position at the University Botanical Garden, where she remained until her retirement in 1936.

Resvoll performed extensive field research both in Norway and abroad. She investigated the presence of hibernation buds, concluding these structures were vestigial traits inherited from temperate-zone ancestors. Throughout her career, she published numerous studies on arctic ranunculus morphology, primary vegetation succession in Værdalen, and the biological characteristics of Rubus chamaemorus.
Advocacy and Public Life
Beyond her scientific research, Resvoll maintained a consistent commitment to the women's rights movement. She served as a board member of the Norwegian Association for Women's Rights starting in 1901 and took an active role in the women's suffrage movement. Additionally, she led the Norwegian Female Student’s Club and became one of the first women elected to the Norwegian Academy of Science and Letters. She also contributed to education by writing a botany textbook for secondary students.
