Dramatic Changes in Arctic Food Chain

The collapse of Greenland’s lemming population cycle has disastrous consequences for a number of predators. Arctic predators are facing a hungry future. A dramatic collapse in the population of Greenland’s only rodent – the collared lemming – means that the food source for several predators has practically vanished. A recent study, published in the scientific journal Proceedings of the Royal Society B., shows that the dramatic reduction in the number of lemmings may have significant knock-on effects on tropically linked species.
