Global warming increasing the dispersal of flora in Northern forests

As a result of stronger winds caused by global warming, seeds and pollen are being carried over longer distances. An increase in temperature of only a couple of degrees may increase the dispersal of plants in Northern forests and the spread of plant species into forest clearings after felling or f...

DNA analysis shows true dispersal of protozoa
