annette and bruno baur studied the changes in elevation distribution of the land snail alianta arbustrorum on the eight slopes of the swiss national park in the eastern alpes using inventories from 1916-17 and their own survey from 2011-2012. in previous studies the baurs had already documented local population extinctions in urban environments around basel. in that instance they observed reduced hatching rates at temperatures as low as 22 c and no hatching at temperatures of 25 c and above. discuss the changes in elevation distribution for the snail considering climate change and global warming. you must discuss using your knowledge of changes in temperature with elevation and the effect of temperature on reproductive rates of the snail. use the data from the graphs to support your answer.
