Jahi Chappell Sun, 11 Mar 2012 20:25:04 +0000 http://www.esa.org/esablog/?p=6147#comment-36130 This should be utterly unsurprising (which doesn’t stop it from being a neat and well-done piece of work!) Life history theory should straightforwardly imply that commercially cultivated varieties — which are put under immense selection pressure for characteristics like rapid growth, response to synthetic N, proper stalk hardiness for mechanized harvesting, etc. — would be losing (or already have lost) any number of other ecologically significant characteristics. (Not to mention the accumulating evidence of changes–decreases–in nutritional content of many varieties.)
