![]() ![]() In Sweden, where the experiments took place, the southern and central parts of the country are more polluted than the north, which has less industry.Īccordingly, the team found that roundleaf sundew plants in southern Swedish bogs are taking up more nitrogen via their roots than those in northern and central bogs, said study leader Jonathan Millett, a plant ecologist at Loughborough University in the U.K. Throughout the developed world, industrial activities have caused an increase in nitrogen pollution, so that more of the element is seeping into soils via rainfall. (See "Worm-Eating Plant Found-Kills via Underground Leaves.") ![]() But, like other carnivorous species, the roundleaf sundew plant (Drosera rotundifolia) has evolved to live in nitrogen-poor environments by supplementing its diet with insects. Nitrogen is an essential nutrient for all plants. Carnivorous plants in Sweden are so stuffed on nitrogen pollution that they're able to eat fewer bugs-and that may not be a good thing for the plants, a new study says.
