Hot topic It seems more likely that a decline of total precipitation and humidity would be the direct cause of both temperature and fire incidence (“The Long Burn: Warming drove recent upswing in wildfires,” SN: 7/8/06, p. 19).

Playing dead is a lively topic I am amazed that “Why Play Dead?” (SN: 10/28/06, p. 280) concluded that “Scientists have a long way to go to explain why” prey animals play dead. As a veterinarian, I have learned that there are separate centers in the brain dealing with predatory behavior and with hunger. The […]
