Good point, you have argued this well in the past. I agree that there is strong evidence that temp variation can be beneficial. "Is beneficial" may be a strong word. I think there could be more research on the limits to any beneficial effects. In other words, exactly how much and under what circumstances can we generalize this statement?
Also, I wouldn't doubt that bacterial colonies will flux some with temperature. Certain bacteria will probably get a foothold with certain conditions, when conditions change, of course, the advantage may shift. Of course, bacteria can be fairly adaptive as well...
