Differenzierung von Kammmuscheln durch DNA-Analyse

Abstract In the last years scallops have reached a considerable popularity and the import of scallops into the EU has increased about 20 % over the last fi ve years from some 50.000 t to nearly 63.000 t in the year 2010. Scallops are fi shed or farmed, and traded as fresh or deep frozen product. Recently investigation of scallop products of various origins by determining the species using molecular biological techniques showed that the species had been mislabelled in a considerable proportion of samples. Determination of the species was performed by PCR-based DNA-analysis of mitochondrial DNA followed by (i) sequencing the PCR product and (ii) comparison of the DNA sequence with entries in GenBank using BLAST. The deduced sequences of the analysed samples were considerably different from each other allowing the unambiguous assignment of samples to a certain species. Kurzfassung Die Nachfrage von Kammmuscheln in der EU hat in den letzten fünf Jahren erheblich zugenommen. Der Import stieg von knapp 53.000 t im Jahr 2005 um 20% auf annähernd 63.000 t im Jahr 2010. Gehandelt werden Kammmuscheln sowohl als frische als auch als Tiefkühlware aus Wildfängen und Aquakultur. Untersuchungen von Kammmuschel-Proben aus verschiedenen Ursprungsländern und Bestimmung der Spezies auf molekularbiologischer Basis zeigten, dass ein erheblicher Anteil der Proben falsch deklariert war. Die Bestimmung der Spezies erfolgte durch Vervielfältigung eines Abschnitts des 16S rRNA Gens durch Polymerase- Kettenreaktion (PCR), anschließender Sequenzanalyse der PCR-Produkte und Vergleich der DNA Sequenzen untereinander und mit Dateneintragungen in GenBank. Die DNA-Sequenzen der ermittelten Abschnitte der 16S rRNA der Proben unterschieden sich erheblich voneinander und erlaubten eine eindeutige Zuordnung zu jeweils einer Spezies.

Copépodes pélagiques du plateau ivoirien. Utilisation de I'analyse des correspondances dans l'étude des variations saisonnières

Several 'analyses factorielles des correspondences' were used with the numerical data of planktonic copepods issued from a 1 year sampling programme at different stations of the Ivorian shelf. The main results were the following: (1) 'Ecological seasons' approximately corresponding to hydrological seasons may be defined for planktonic populations. (2) Each 'season' is characterized by one group of species, whose maximum abundance occurs in this period. (3) The same definition of ecological season is obtained whether all species present are used or whether only the most important ones are used. (4) The first principal axes may be interpreted as temperature and salinity or as the station's distance from shore.

Analyse phytogéographique comparative des savanes et des forêts de Ngotto (République Centrafricaine)

After several investigations on the savanna and forest of Ngotto (Central African Republic), we propose a phytogeographical interpretation of our data on the systematic (level family), the biological forms, the dispersion of diaspores and phytogeographical elements spectra. These spectra are given regarding both formation type (savanna, forest) to appreciate their originality. Then, a comparaison is driven in order to set up the differences between these two formations.

Les derniers écueils vers la parité politique en Belgique: Une analyse des élections régionales de 2004

In Belgium, gender-parity has been compulsory for all party lists (in local, regional, federal and European elections) for several years. As a result, the proportion of women has risen from a fourth up to a third of the deputies. Yet, strict parity is still far from realised. This article seeks to establish what causes this glass ceiling, namely the parties' reluctance to place female candidates in the top positions or even as the front-runner. In a proportional representation system with half-open lists, and especially when the constituencies are small, this automatically leads to a smaller proportion of women among the elected deputies. One important reason for the parties' reluctance to rank female candidates higher is their assumption that women are less effective as "election locomotives" than men. However, the analysis of the Belgian election results makes clear that this is not the case. Female candidates in top positions are as successful as their male counterparts. © (2008) Swiss Political Science Review.

"L'Invitation au voyage" de Baudelaire :une analyse évocative

This paper presents a detailed analysis of Baudelaire's poem ''L'Invitation au voyage''. It aims to understand the general meaning of this poem, showing that Baudelaire's ''voyage'' comes less to an ideal paradise than to a kind of voluptuous purgatory. We associate together dimensions of the poem that are usually treated separately :biographical background, stylistic and intertextual borrowings (orientalized Holland, Goethe's Mignon, popular song and romance, Weber's music, Biblical episodes), formal structure and cognitive effects. Our method is based on Benoît de Cornulier's theory of metrics, Searle and Vanderveken's speech act theory and Marc Dominicy's theory of poetic evocation. As Dominicy's theory is quite recent, our article provides substantial summary and clarification of its main theoretical and methodological hypothesis.

Ist patriotischer Nationalstolz wünschenswert? Eine differenzierte Analyse seiner psychologischen Bedeutung

Previous studies found that patriotic national pride (e.g., pride in democracy) - as opposed to nationalistic national pride (e.g., pride in being German) - has an attenuating effect on ethnocentrism, which is desirable from a democratic standpoint. Here it is hypothesized (1) that patriotic pride can be ascribed to the three components national identification, importance of democratic aspects of Germany, and belief in existence of democratic aspects of Germany, and (2) that these components exert in part conflicting effects on ethnocentrism and other variables. In two questionnaire studies (N-1 = 121, N-2 = 150) it is shown that (1) the three components do predict patriotic national pride and (2) the democratically desirable effects of patriotic pride trace back primarily to the importance of democratic aspects. In conclusion, from a democratic standpoint, it is positive valuation of democratic aspects and not patriotic pride that should be nurtured.
