Genetic data from Staurosira (Fragilariophyceae) sedimentary DNA

Genetic investigations on eukaryotic plankton confirmed the existence of modern biogeographic patterns, but analyses of palaeoecological data exploring the temporal variability of these patterns have rarely been presented. Ancient sedimentary DNA proved suitable for investigations of past assemblage turnover in the course of environmental change, but genetic relatedness of the identified lineages has not yet been undertaken. Here, we investigate the relatedness of diatom lineages in Siberian lakes along environmental gradients (i.e. across treeline transects), over geographic distance and through time (i.e. the last 7000 years) using modern and ancient sedimentary DNA. Our results indicate that closely-related Staurosira lineages occur in similar environments and less-related lineages in dissimilar environments, in our case different vegetation and co-varying climatic and limnic variables across treeline transects. Thus our study reveals that environmental conditions rather than geographic distance is reflected by diatom-relatedness patterns in space and time. We tentatively speculate that the detected relatedness pattern in Staurosira across the treeline could be a result of adaptation to diverse environmental conditions across the arctic boreal treeline, however, a geographically-driven divergence and subsequent repopulation of ecologically different habitats might also be a potential explanation for the observed pattern.

Immigration and free movement in an unusual electoral race: what implications for the next political cycle? EPC Policy Brief, 20 May 2014

Immigration and freedom of movement of EU citizens are among the main issues debated throughout the European Parliament election campaign and have some potential in determining who tomorrow’s EU leaders will be. This Policy Brief looks at how the two policies are debated at national level – in France, Germany and the UK – and at EU level between the ‘top candidates’ for European Commission Presidency – Jean-Claude Juncker (EPP), Ska Keller (Greens), Martin Schulz (PES) and Guy Verhofstadt (ALDE) – who have participated in several public debates. Two different campaigns have been unfolding in front of EU citizens’ eyes. The tense debate that can be identified at national level on these issues, is not transferred to the EU level, where immigration and free movement are less controversial topics. Furthermore, although participating in European elections, national parties present agendas responding exclusively to the economic and social challenges of their Member State, while the candidates for the Commission Presidency bring forward ‘more European’ programmes. Hence, several aspects need to be reflected upon: What will the consequences of this discontinuity be? How will this impact the future European agenda in terms of immigration and free movement? What institutional consequences will there be? Answering these questions is not a simple task, however, this paper aims to identify the parameters that need to be taken into account and the political landscape which will determine the future EU agenda in terms of immigration and free movement.

European Union Leadership and Enlargement in 2014. Jean Monnet/Robert Schuman Paper Series Vol. 14 No. 14, July 2014

On July 15, 2014 the European Parliament confirmed the new European Commission President. An absolute majority was needed for this purpose, and the 422 votes “For” cleared the 376-vote threshold in the legislative body of 751 members. A Grand Coalition has been formed among the three largest political parties: the European People’s Party (EPP), the Progressive Alliances of Socialists Democrats (S&D), and the Alliance of Liberals and Democrats for Europe (ALDE). Considering policy decisions going forward, the European Union (EU) faces the pressing question: Will there be more, less, or similar power from the EU? There are a greater number voices from across the political spectrum contributing to the democratic plurality. European leaders may regain trust by acknowledging that future governance will not be “business as usual” as the reform agenda gets underway. 2014 has been an exciting and important year in European politics. “This time is different” was the motto for the European Parliament’s election campaign. This essay analyzes recent EU political trends with the new Commission leadership and the Parliamentary elections results. The Parliamentary elections, held in late May, and the new European Commission, planned to be in place in the autumn, influence the leadership direction of the 28-member bloc. Additionally, this year on July 1 Croatia celebrated the first anniversary of joining the EU in 2013. Leading the way for candidate countries, Croatia embraces the democratic politics and capitalist market economics embodied by the EU. The greater number of seats held by newer political parties in the European Parliament demonstrates increasing plurality in the EU democracy. The Parliamentary elections have taken place every 5 years since 1979. In this eighth legislative session, the EPP and the S&D remain the largest parties represented, with 221 and 191 seats respectively. As the EU has evolved, a greater number of voices influence politics. The ongoing point of contention on a host of policies is national sovereignty in relation to pooled sovereignty in the EU. The European Parliament is important for democracy in EU governance since it is the direct link from the national citizens to their elected leaders at the supranational level. The representatives of the European Commission are appointed by the national governments of Member States, and their heads of government are the representatives to the European Council. These three political institutions – the European Parliament, the European Commission, and the European Council – together with other important institutions, including the European Court of Justice Luxembourg, form the EU. The new European Commission President is Jean-Claude Juncker, former Prime Minister and Minister of Finance of Luxembourg (1995-2013). After being nominated by the European Council on June 27, his candidacy was voted on by the European Parliament on July 15, according to the guidelines of the Lisbon Treaty. The leadership for the President of the European Commission has been an important issue, considering Britain’s deliberations on whether or not to stay in the EU in the face of a future national referendum. Voting on June 27, among the European Council on the nomination of Commission President-Designate Juncker, was 26 in favor and 2 opposed. Only Viktor Orbán, the prime minister of Hungary, joined David Cameron, the prime minister of the United Kingdom (UK), with a negative vote (Spiegel and Parker 2014). The UK had not been supportive, being concerned that Juncker embraces the policies of a federalist, prioritizing an ever-closer union above the interests of individual Member States. Historically, since joining the predecessor institution of the European Economic Community in 1973, the UK has had a relatively independent attitude about participation in the EU.

Pollen, DNA and Vegetation records from surface sediments of lacustrine lakes along a forest tundra - tundra transect at the Taymyr peninsula, northern Siberia

Reliable information of past vegetation changes are important to project future changes, especially for areas undergoing rapid transitioning such as the boreal treeline. The application of detailed sedDNA records has the potential to enhance our understanding of vegetation changes gained mainly from pollen studies of lake sediments. This study investigates sedDNA and pollen records from 31 lakes along a gradient of increasing larch forest cover in northern Siberia (Taymyr Peninsula) and compares them with vegetation field surveys within the lake's catchment. With respect to vegetation richness, sedDNA recorded 114 taxa, about half of them to species level, while pollen analyses identified 43 pollen taxa. Both approaches exceed the 31 taxa revealed by vegetation field surveys of 400 m**2 plots. From north to south, Larix percentages increase, as is consistently recorded by all three methods. Furthermore, tundra sites are separated from forested sites in the plots of the principal component analyses. Comparison of ordination results by Procrustes and Protest analyses yields a significant fit among all compared pairs of records. Despite the overall comparability of sedDNA and pollen analyses certain idiosyncrasies in the compositional signal are observed, such as high percentages of Alnus and Betula in all pollen spectra and high percentages of Salix in all sedDNA spectra. In conclusion, our results from the treeline show that sedDNA analyses perform better than pollen in recording site-specific richness (i.e. presence/absence of certain vegetation taxa in the direct vicinity of the lake) and perform as good as pollen in tracing regional vegetation composition.
