In memory of colleagues: losses of the last five years (2020–2024)

A review of information about Ukrainian theriologists and zoologists related to theriology who passed away in the last five years, from 2020 to 2024. A total of 14 colleagues passed during these years are listed, including two colleagues in 2020, four in 2021, two in 2022, one in 2023, and five in 2024. Most of them died not of advanced age, but of illness (primarily due to Covid or related complications), and three colleagues died in the war. Most of them have been addressed in the latest issues of Novitates Theriologicae: NT14 (I. Delegan, M. Kovtun, O. Mykhalevych, V. To¬karsky, and O. Tsvelykh), NT15 (V. Bulakhov, O. Voblenko, and I. Polishchuk), NT16 (L. Tara¬nenko), and NT17 (S. Pasichnyk). The rate of losses significantly exceeds the emergence of new names.
