This paper analyzes the capabilities of three different governance regimes for adequately handling uncertain and unknown effects of genetically modified (GM) crops. Adequate handling requires the development of sound procedures for identification of uncertainty and ignorance (U&I), reduction of U&I, decisions on how to treat irreducible U&I and monitoring of unexpected effects. The nature of U&I implies, however, that these procedures will be highly incomplete. Governance mechanisms that facilitate cooperative adaptation and communicative rationality are therefore needed. The three governance regimes (GRs) compared are: GM-crops are produced by private firms and these firms are made liable for harm (GR1); GM-crops are produced by private firms and the government decides whether the crops should be marketed (GR2); and GM-crops are produced and the government decides whether the crops should be marketed (GR3). The effect of bringing the civil society into the decision-making process is also analyzed. GR3 will be stronger in cooperative adaptation and communicative rationality than GR2. Public research organizations have fewer conflicts of interest with the government than private firms, and academic norms are important. Difficulties in proving harm and identifying the responsible firm will make GR1 weak in cooperative adaptation and communicative rationality.

The northernmost range of beech (Fagus sylvatica L.) is in southern Norway and consists of two distinct and isolated distributions, a single population at Seim in West Norway and several adjacent populations in Vestfold, East Norway. The modest beech pollen deposits beyond these main distributions suggest that the Norwegian beech distribution has never been an extension of the south Scandinavian range. We used genetic markers and historical sources to trace the ancestor populations for the beech at Seim and Vestfold, hypothesising Denmark as the most likely source. Nuclear inter-simple sequence repeat markers, amplified by polymerase chain reaction (PCR), were applied to estimate genetic distances between beech populations in Norway, England and Denmark. The variation in chloroplast DNA polymorphism was estimated using PCR-restriction fragment length polymorphism. The nuclear genetic data indicate Denmark as a source for the beech in Norway, although the data are less certain in the case of Seim than in that of Vestfold. The populations from South England were genetically different from most Scandinavian populations. The genetic variation within Norwegian populations was only slightly lower than that of the English and Danish populations, questioning birds as vectors for dispersal. Thus, the pollen data and our results are in accordance with the intentional introduction and documented human migrations across Skagerrak before and during the Viking Age.
