Hippos in the Great Ruaha River in Tanzania face a profound loss of their habitat during the dry season. The river has much less water during this season than in previous decades because it is increasingly extracted for human use. As a consequence, the river dries up. Researchers from the German Leibniz Institute for Zoo and Wildlife Research (IZW) have now examined how this affects the distribution of hippos. Their results reveal extensive and long distance movements, as hippos search for vital daytime resting sites. The study has been published in the scientific journal “PLOS ONE”.
