<p>Nice place to be a researcher, isn’t it?</p> <p>But that’s only because now it’s summer. </p> <p>In winter, temperatures reach here -45ºC. </p> <p>These biologists wander around northern Sweden…</p> <p>… to study how subarctic plants survive in this extreme environment. </p> <p>Colour of the flowers is one of those survival mechanisms. </p> <p>Flowers boast more colours when bumblebees are their main pollinators. </p> <p>If pollinators are mainly flies, flowers tend to be merely white or yellow. </p> <p>And these researchers have come well above the Arctic Circle to study if the same pattern reproduces here.</p>
