“If you think about a garden, there are always unwanted weeds that spread everywhere because they can utilise resources, like nutrients, very well,” said the lead author of the study, Dr Sabine Rumpf.
Dr Rumpf is a professor at the University of Basel in Switzerland.
“They typically grow fast and produce many offspring, while other plant species are simply outgrown by them because they can’t exploit the resources as fast as the weeds do.
“This is similar to what’s happening in mountain environments. High alpine species invest their resources in ‘body armour’ to persist in the long-term – most of them are very long-lived but don’t reproduce very often successfully.”
