An arctic hare's coat color changes from white to brown each spring in response to a change in its melatonin level. This change is triggered by increasing daylength. As a result of ongoing global climate change, the arctic snow melt is occurring earlier and earlier. Explain why this change in the annual temperature pattern has increased the number of hares that are killed by predators.
