Paul F. Maycock Collection:
This collection of over 30,000 specimens is housed at TRTE. During the course of his research in plant communities in Ontario, Québec, temperate Europe, and eastern Asia, Professor Maycock and his students and research colleagues made extensive collections of specimens to serve as vouchers for their ecological data. His research focused on forest communities throughout Ontario but he also visited remote regions of Northern Ontario studying subarctic communities.
Josef Svoboda Collection:
Professor Svoboda and his students undertook ecological research in the Canadian arctic, particularly Ellesmere Island, Nunavut. Considerable numbers of specimens were collected during the course of this research and those are incorporated in TRTE.
