It is the favorite past time of every invasion biologist since H. G. Baker in the 1960s to make lists of traits which distinguish invaders. We’ve been doing it for at least 50 years, and yet, no list ever seems to satisfy. There are always exceptions – a majority of cases seem to be exceptions, really. And maybe that’s because we need to think about it in more dimensions.
The basic recipe for beer goes something like this.You take starch from a cereal grain (the fruit of a domesticated species of Poaceae, or Grass family), use enzymes to convert that starch into sugar, feed the sugar to a microbe capable of fermentation (such as a yeast or bacteria), which then poops out alcohol and carbon dioxide. It’s a beautiful process. You see the barley – brewer’s yeast – hops combo all the time. But why be so predictable?
What happens when you introduce invasive burrow dwelling rodents to an island populated by burrow nesting birds?
Ok, so they aren’t plants. But they are invasive.
