Our Dr. Don Reid has co-authored a paper on the effects of climate change on Arctic food webs, published online last week in Nature Climate Change. The study found that as climate change progresses, predation on herbivores is increasing in the Arctic, going up by 4.5% for every degree Celsius that the temperature increases! However, herbivore body size was an important factor as large herbivores largely escaped predation. The study's findings show that predators were the main drivers of the Arctic food chain, just like in African savannahs and the North American Great Plains - in addition, the importance of herbivore body size in determining predation intensity was similar to trends in African savannahs. The findings raise the possibility that most terrestrial ecosystems may be governed by the same rules and could be a first step toward a universal theory of terrestrial ecosystem functioning.
