Talk:Host–parasite coevolution

Oak - Powdery Mildew Example
Oak trees and powdery mildew are a common host-parasite interaction in nature. I think adding this example would be beneficial to the page. Some research of this interaction has used methods testing a third variable such as altitude which can be described as a method for studying the third variable effect of coevolution. Due to the varying environment, the response to selection differs, and therefore the phenological changes in the population of both the plants and fungi will differ.c Stephenoff.2 (talk) 20:36, 1 October 2014 (UTC)
