Nearly 25 years later, the infamous Iron Curtain is still having an impact on Europe -- on its animals at least. A new study found that even over several generations, deer still avoid areas that were once lined with electric fences, placed there by what was once Czechoslovakia (now the Czech Republic).
Using GPS-equipped collars, researchers monitored about 300 Czech and German deer, finding that a border that now doesn't exist still separates two populations. This is mainly because fawns naturally follow their mothers for the first year of their life and learn from them where to go, Pavel Sustr, a biologist who led the project, told the Guardian.
"It was fascinating to realise for the first time that anything like that is possible," Sustr said, adding that "the border still plays a role."
