Genetic variation at microsatellite markers was used to quantify genetic structure and mating behavior in a severely fragmented population of the wind-pollinated, wind-dispersed temperate tree Fraxinus excelsior in a deforested catchment in Scotland. Remnants maintain high levels of genetic diversity, comparable with those reported for continuous populations in southeastern Europe, and show low interpopulation differentiation (Theta = 0.080), indicating that historical gene exchange has not been limited (Nm = 3.48). We estimated from seeds collected from all trees producing fruits in three of five remnants that F. excelsior is predominantly outcrossing (t(m). = 0.971 +/- 0.028). Use of a neighborhood model approach to describe the relative contribution of local and long-distance pollen dispersal indicates that pollen gene flow into each of the three remnants is extensive (46-95%) and pollen dispersal has two components. The first is very localized and restricted to tens of meters around the mother trees. The second is a long-distance component with dispersal occurring over several kilometers. Effective dispersal distances, accounting for the distance and directionality to mother trees of sampled pollen donors, average 328 m and are greater than values reported for a continuous population. These results suggest that the opening of the landscape facilitates airborne pollen movement and may alleviate the expected detrimental genetic effects of fragmentation.
Epistemological and philosophical refluxes in the constitution of the Pecheuxtian Discourse Analysis

This article aims at verifying influences of epistemological and philosophical basis constitutive of the French Discourse Analysis (DA), more specifically that one based on the studies of Michel Pêcheux. For him, the social class, the socio-historic and cultural interpellation of the subject are determining of meanings and are linked with the Marxist historical materialism, via Althusser, as well as with the lacanian Psychoanalysis and with the saussurian Linguistics. His writings also influences by Michel Foucault, especially during the so-called “third phase” of the DA. Thus, between the two philosophical lines which cross science for centuries, that is, the formalist-logicist and the rationalist-idealism, the Discourse Analysis has a strong connection with this last one.

The story of the fall of the Berlin Wall was an aspect of the “imagination gap” that we had to wrestle with as journalists covering the collapse of the Eastern Bloc in Europe. It was scarcely possible to believe what you found yourself reporting, and that work became a two-track process. On one hand a mass social movement was dictating the pace and direction of events; on the other, the institutional business of politics as usual, to provide a framework for all the change that was happening, had to be managed – and reported on. In later analyseds we could see, that crisis in the Soviet Union led to the crisis over the Berlin Wall; and from the fall of the Wall, came Germany’s reunification, and with that also, formation of the European Union as it is today. The government of the Federal Republic of Germany convinced its neighbours that a reunited Germany, within an expanded EU, would be a very acceptable “European Germany” -- not the leader of a “German Europe”. It committed itself financially, supporting the new Euro currency. The former communist states of Eastern Europe demanded to join and expand the EU; in order to remove themselves from the Soviet Union, enjoy human rights, and share in Western prosperity. So today, following on from the events of 1989, the European Union is an amalgam of 27 member countries, with close to 500 million citizens and accounting for 30 % of world Gross National Product.
