Evidence from palynology and fossil records have shown that, in the past, plant species have successfully responded to environmental change by 1) remaining within the modified climate by tolerance or adaptation, 2) migrating to track suitable conditions, or most likely a combination of both (Engler et al., 2009).	cache/bjpt-54223.pdf	txt/bjpt-54223.txt
