An international group of 49 scientists from 12 countries assembled at Brock University, St. Catharines, Ontario, Canada, from June 22-27, 2025, for the 11th International Symposium on Testate Amoebae (ISTA-11 Niagara). The meeting, jointly organized by the International Society of Testate Amoebae Research (ISTAR) and the Canadian Association of Palynologists (CAP), marked a significant milestone as the first ISTA meeting held in North America. Participation included 19 students, underscoring strong engagement from early-career researchers. The largest national delegation was from Canada (17 participants), followed by China, Switzerland, and the United States (six participants each). The scientific program comprised 41 oral and 12 poster presentations, reflecting the continued growth and diversification of research on testate amoebae.
