This is an entirely different article than the draft we were allowed to see before this went to print and there are quite a few scientific and mathematical statements that are not accurate in relation to our research. I would highly suggest for the full picture, including a discussion of the differences in this work from the work done by previous people, that one reads and considers the paper by Drs. Kealy and Wollkind found in the Bulletin of Mathematical Biology.

"Dr kealy's model,by contrast,is spot-on."

What model?
Which contrast?
Where are spots?

Have seen cats eating grass after winning their coat as kittens.

Any Bibliography for peer review?

Melt down for sciences and scientists,no wonder financial and power meltdown for politics, power stations globally.

Yes - these kind of patterns are actually called "Turing" patterns. We presented at the Joint Meetings in a special session dedicated to honoring the "Life and Legacy" of Alan Turing. His base work on these kind of patterns is rarely discussed, but applied often. You can find the slideshows and more information on Turing on the website from the session here: http://mathsci2.appstate.edu/~jlh/tsjmm.html. The generation of the tiger-stripe patterns can also be found in our paper and in more detail in the references for our paper.

Nice work, but it's not exactly clear to me how this adds to the work alredy performed by for example Klausmeier and Rietkerk, also cited in the article
