My professor Ignacio Chapela had been serving as a scientific director for four indigenous communities which had banded together to manage their natural resources.

This is a modified version of a German-language article that appeared in Das GoetheanumDec. Office Phone Number natude Fourth, we provide solid biological data and concepts to inform what has been traditionally a fickle and speculative market which is, nonetheless, very important across the Northern Hemisphere.

Immoral Maize – definitive account of Chapela affair

These are the basic questions of ecology: It is subsidised from beginning to end by US taxpayer dollars. It is the standard tool for GMO identification used by regulatory agencies throughout the world for accepting or rejecting shipments of GM-free grain. What natuure the biggest threats to them?

The Case of Mexican Maize

GRAIN is a small international non-profit organisation that works to support small farmers and social movements in their struggles for community-controlled and biodiversity-based food systems. With this manuscript we establish several new concepts in the field of coevolutionary biology of fungi. The most recent culmination of my work on an important group of angiosperm-associated fungi, with which I have been working since my doctoral dissertation.

We work with eukaryotic microbes, and we are most focused on those eukaryotic microbes living in terrestrial ecosystems. The standard author abbreviation Chapela is used to indicate this person as the author when citing a botanical name. Incredible amounts of money go into the production of this grain that receives subsidised water, soil, machinery and oil; is subsidised in international markets; and subsidised again in Mexico through distribution.

We needed natjre transgenic-negative control, and what better place than the highlands of Oaxaca, the birthplace of maize? The second reviewer called the results so unexpected and unbelievable that their validity could be called into question.

What are the implications of your work for farmers in Mexico, and small fhapela in particular? Biodiversity – cornucopia of knowledge. Issues Summary, CEC, www. The third major threat to farmers is the loss of markets owing to the pollution of their maize crops.

Since the study that was published in Nature, his work has become more focused on transgene ecology – ie how genes move about in the environment.

To our surprise we found it in a diversity of places within the native maize genome. Nature’s handling of our paper suggests that it was under pressure from the industry camp.

For traditional ecologists, there was no question about the identity of the organism at stake: In this paper, we take a biogeographical and evolutionary approach to questions of coevolution, host-specificity and adaptation. I am concerned about the ignacjo on science.

A year and a half on from the publication of your paper in Nature, what is your perspective on why there was such a strong reaction to this paper? In this paper, we resolve a major question emerging from the last 8 years of use of stable isotope analysis for ecological inference in the field. Perhaps the greatest advantage of viral marketing is that your message is placed into a context where it is more likely to be considered seriously. If the journal were truly interested in promoting open scientific discourse, we would expect them to publish the article, especially after having retracted Quist and Chapela’s work.

One question that came up for them was whether GM crops were an issue they should be concerned about. This response draws from my work and experience with Latin American conservation reality on the ground. What we are seeing more and more is that the science of substantiating facts is overriding science as a process, which is all about questioning and re-examining our assumptions, in order to lead us to a better understanding of reality.
