The war in Ukraine appears to have grounded a large space-based wildlife tracking project.
The past 2 weeks have been very good—and very bad—for Martin Wikelski and Walter Jetz. In a key proof of principle of their space-based wildlife tracking project, they published a paper tracing the travels of 15 species, including the meanderings of an endangered saiga antelope across Central Asia and the marathon flights of cuckoos from Japan to Papua New Guinea.
To understand animal behavior and how humans are influencing it, researchers have increasingly put GPS tags on animals and tracked them with hand-held or ground-based receivers. But tagged animals often move out of range, and the tags were expensive, so few individuals could be tracked. ICARUS, founded in 2002, aimed to lift tracking into space and develop cheaper tags, affordable by researchers worldwide.
The tags have provided new and sometimes surprising insights, Jetz, Wikelski, and colleagues reported on 8 March in. The technology traced animals’ entire journeys, not just the end points, yielding clues about why some birds are declining. But shortly after the war in Ukraine began last month, all data downloads from the space station stopped. No one knows exactly why, although Wikelski presumes it’s because the German and Russian space agencies no longer collaborate.
