Thanks for joining IRAC 2022! Want to keep up with all things radar aeroecology? Join the mailing list at https://groups.google.com/g/radar-aeroecology.
We cordially invite you to the 3rd International Radar Aeroecology Conference (IRAC 2022) in Davos, Switzerland. The conference takes place on 25-26 June 2022, directly before the World Biodiversity Forum. We look forward to welcoming many of you in person in Davos, but we will also offer online participation and make special arrangements for online participants presenting from different time zones. The conference will be a full 2-day event with plenary presentations, a poster session, and possibilities for informal discussions and networking.
We invite proposals for oral and poster contributions, fitting one or more of the conference themes and presented as part of thematic sessions:
- Spatio-temporal movement patterns of birds, bats, and insects and their environmental influences
- Methodological advancements - classification and identification algorithms, radar technology, data infrastructure
- From radar aeroecology to biodiversity
- Applied radar aeroecology - the knowledge base for conservation and management
We have invited renowned speakers who will give an introductory overview for each session:
Silke Bauer - Silke is a senior researcher at the Swiss Ornithological institute, and her core research interests are large scale migration patterns and the multitude of ecological effects migrants can have on resident communities visited during their journeys.
Jeff Buler - Jeff is professor at the Department of Entomology and Wildlife Ecology at the University of Delaware, where he established the Aeroecology Program in 2011. He is an international leader in the development of novel methods for using weather surveillance radars to study the broad-scale distribution, movement, and habitat use patterns of flying animals, particularly migratory birds.
Boya Gao - Boya is a post-doctor at plant protection college, Nanjing Agricultural University who researches insect migration and radar entomology.
Judy Shamoun-Baranes - Judy is a professor at the Institute for Biodiversity and Ecosystem Dynamics at the University of Amsterdam and fascinated by animal movements and their biodiversity implications.
We gratefully acknowledge the financial support of the following organizations:
Times are indicated in local times for Davos, Switzerland (CEST, UTC+02:00). See the current time in Davos.
