The IRISCC (Integrated Research Infrastructure Services for Climate Change Risks) project has launched its First General Call for Transnational and Virtual Access. As part of this call, 13 eLTER Sites and eLTSER Platforms are included among the infrastructures available for access. These sites represent some of Europe’s most advanced long-term ecosystem research locations and are situated across Germany, Finland, Hungary, Portugal, Spain, Belgium, Austria and Israel.

 (1) Atmospheric transport affects glacial microbes; (2) Community assembly processes are dynamic as glacial microorganisms move downstream; (3) Glacial microbes participate in biogeochemical cycles and feedback to climate; (4) Impacts of mixed pollutants on glacier habitats deserve deeper attention; (5) Climate change, pollutants, and microbes combine to affect glacier habitats.
