As the world is getting warmer and warmer many organisms native to lower latitudes or elevations are moving higher.
However, novel organisms moving into a new habitat could disturb the ecological balance, which has been established over a long period. Plants and herbivores are characterized by long-term co-evolution, shaping both their geographic distribution and the characteristics that they display in their occupied sites.
At higher elevations, this is seen in insect herbivores being generally less abundant and plants in turn being less well defended against herbivores, because of lower energy and shorter growing seasons. In contrast, low-elevation plant species defend themselves against more abundant and diverse herbivores, whether by means of spikes, thorns or hair, or by toxic substances. Climate change could disturb this ecological organization.Read More »
