    Will Killing This Invasive Plant Harm Bees?

  • However, new research from an international team of researchers finds that a disturbance -- such as fire or grazing -- actually increased the success of yellow starthistle far more in non-native than in its home regions.


  • When exposed to increased carbon dioxide, precipitation, nitrogen and temperature--all expected results of climate change--yellow starthistle in some cases grow to six times its normal size while the other grassland species remained relatively unchanged. Top News
