The Hungarian Academy of Sciences has announced its ‘Momentum MSCA’ postdoctoral fellowship for the first time, enabling outstanding researchers to join the work of Lendület research groups for a period of 1–3 years. The MTA-ÖK Lendület Fluvial Ecology RG received seven applications, of which two candidates were awarded postdoctoral positions for three years, starting from 1 January 2026. Ghoufrane Derhy will focus on a trait-based comparison of riverine and lacustrine food webs, while Junyao Gu will investigate the relationship between molecular-based biodiversity and ecosystem functioning (BEF) across multiple trophic levels in Danube plankton communities. We extend our congratulations to the postdoctoral researchers and the hosting lab!
