We study the possible influences of the Russian conflict in the Ukraine on Russia’s research productivity and international collaboration in science. For this purpose, we introduce and apply two recently developed indicators of relative intensity and balance in international collaboration. To see whether longitudinal trends have changed recently, we combine a long-term perspective based on annual updates since the year 2000 with a short-term perspective based on monthly updates since the beginning of 2022. The clearest change is that the productivity of Russian science, as measured within Web of Science, has dramatically decreased recently after several years of growth. However, the degree of international collaboration is only slightly affected. Consequently, while international collaboration decreases in absolute numbers, this decrease does not explain the general decline in Russian science, which must instead be explained by internal factors. Our conclusion is that the Russian conflict in the Ukraine has not considerably affected the long-term patterns and trends in international scientific collaboration, except in fields of research that heavily rely on large multinational infrastructures established through state agreements such as Particles and Fields in physics.
