Plants moved downhill, not up, in warming world

Scientists now challenge a widely held assumption that plants will move uphill in response to warmer temperatures. Many forecasts say climate change will cause a number of plants and animals to migrate to new ranges or become extinct. That research has largely been based on the assumption that temperature is the dominant driver of species distributions. However, new research reveals that other factors, such as precipitation, may be more important than temperature in defining the habitable range of these species.
