The editors of Nature Biotechnology seem to have gone completely insane!  Hodgson seems to be claiming Arpad Pusztai did not do any experiments at all!  Those morons certainly should apologize for such a claim!  They may be taking "science" lessons from Avery!

Taking a leaf out of Arpad Pusztai’s studies, researchers at the University of East Anglia have published work on the impacts of GM crops "without doing any experiments."

Computer modelers Andrew Watkinson and colleagues at East Anglia modeled the effects of GM herbicide tolerant beet on the population dynamics of a weed that is an important food source for farmland birds (Science, 289, 1554-1557 2000;MEDLINE).

The model predicts that bird populations will be low where weed densities are low, and that the use of GM herbicide tolerant crop will reduce weed populations.  They extrapolate that GM crops will reduce bird populations.

However, among the real-life facts the model ignores are field studies showing that herbicide-tolerant beets allow farmers to maintain weeds longer (because they can be treated after crop emergence not before), and the possibility that greater efficiency of GM crops may allow more land to be "set aside" for wildlife.
