Scientific collaboration often begins with a simple conversation, an exchange of ideas that transcends borders. For Bruce Rhoads, a professor of geography and geographic information science and river dynamics expert, and Alexander Sukhodolov, a research group leader at Germany’s Leibniz Institute for Freshwater Ecology and Inland Fisheries, that first conversation came in the form of an email nearly three decades ago. What started as an inquiry about river confluences grew into a lasting professional and personal connection, most recently leading to their coauthored study in Science examining the environmental consequences of the Kakhovka Dam’s destruction.
