Based on the data gathered for this study,researchers predict that three bamboo species which make up almost the entire diet of the pandas in Qin Mountains,will all but disappear in a warmer climate.
“Results suggest that almost the entire panda habitat in the region may disappear by the end of the 21st century,”the study’s authors write.
The calculations are based on different warming scenarios(方案)projected by the Intergovernmental Panel on Climate Change—ranging from rises of 2℃ to 5℃ in summer by the 21st century’s end,and 3 to 8℃ in winter.
These predictions were made based on data on rainfall and emission of greenhouse gas as well as historical growth patterns,to consider the future of bamboo.
Already,deforestation(滥伐森林)is threatening the survival of about half of all bamboo species worldwide.
The researchers say bamboo distribution has historically fluctuated in response to changes in the climate.
In modern times,though,even if other areas were to become climatically more suitable for bamboo growth,these would be far away and fall outside the present network of protected panda reserves.
The findings should be used “for proactive planning to protect areas that have a better climatic chance of providing adequate food sources”.
