Dr John A. Thomson

Honorary Research Associate, Pteridophytes

Research Interests

Taxonomy, biogeography and evolutionary relationships of bracken ferns (Pteridium) worldwide; bracken toxins, insects feeding on bracken

Current Projects

  1. Relationships in Pteridium based on chloroplast and low copy-number nuclear gene sequences, leading to a revised worldwide taxonomy for the genus
  2. Morphotypic polymorphisms in Australian brackens in relation to adaptation to local climatic conditions
  3. Adaptation of bracken-feeding insects to toxins produced by these plants.
