Wildlife ecologists who study the effects of climate change assume, with support from several studies, that warming temperatures caused by climate change are forcing animals to move either northward or upslope on mountainsides to stay within their natural climate conditions. But a new study of lowland and higher-mountain bird species now shows an unexpected… inconsistency in such shifts…
…82 percent, or nine of the 11 high elevation [bird] species [White Mountains, NH] analyzed showed evidence of shifting downslope, while 10 of 16 or 63 percent of lowland species showed evidence of shifting upslope….
