BT - la importancia del viaje de Humboldt para Europa y América Latina N2 - Der Beitrag “Humboldteanisierung des Westens? Die Bedeutung der Reise Humboldts für Europa und Lateinamerika” behandelt der preußischen emprischen Universalgelehrten, in Übereinstimmung mit dem von Ottmar Ette entwickelten Konzept, als einen, wenn nicht den wichtigsten Begründer der westlichen Moderne. Im Gegensatz zu den bekannten Gründern der Moderne (Descartes, Kant, Buffon, Schiller, Hegel, Marx ... etc.) war Humboldt Empiriker und Globaldenker und er tat dies auf transkulturelle Weise, manchmal auch schon auf interkulturelle Weise; allerdings meist auf Basis der römisch-klassizistischen Denktradition und Ästhetik Europas. Der Beitrag arbeitet drei Wissenstypen Humboldts heraus und versucht zu zeigen, dass der Universalismus Humboldt wichtige interkulturelle Grundlagen in der Kommunikation mit amerikanischen Gelehrten und im amerikanischen Empirismus (“lokales Wissen”) hat. Die Bedeutung einer solchen Konzeption der Humboldt-Reise zeigt sich – in der Negierung – in den gegenwärtigen Debatten um Diasporas und “Race” im atlantischen Westen (“Black Atlantic”). Humboldt Kenntnisse der amerikanischen Sklavereien und seine absolute Verurteilung der Sklaverei ist dabei nicht präsent. Im zweiten Teil zeigt der Beitrag mögliche Lesarten der Humboldt-Tagebücher, indem er “imaginäre Humboldt-Essays” konstruiert. N2 - The article “Humboldization of the Western world? The importance of the travel of Humboldt for Europa and for Latin America”, treats the empirical Prussian Scientist as a globalist (Universalgelehrten), in accordance to the conceptualization made by Ottmar Ette. Humboldt was one, if not the most important founder of Western moderne. As opposed to the well-known founders of the moderne (Descartes, Kant, Buffon, Schiller, Hegel, Marx ... etc.), Alexander von Humboldt was an empirical and a global thinker. He did this in transcultural manners, sometimes already in intercultural manners. But most of times, his point of view is based in the European tradition of roman-classicist and aesthetic thinking. The article tries to demonstrate three types of knowledge in Humboldt and also, that the humboldtian universalism has important intercultural bases in the comunication with American scientists and in the American empiricism (“local knowledge”). One importance of such a conceptualization of Humboldt is shown – in negation – in the actual debates over diaspora and race in the Atlantic world (“Black Atlantic”). Humboldt knowledge of American slaveries and his absolute condemnation of slavery in his “Island of Cuba” is not present in these debates. In the second part the article demonstrates possibles manners of reading the diaries of Humboldt, by constructing “essais imaginaires” about colonialism, slavery, Peru, the Pacific ocean etc. KW - 1799-1804 KW - Europa KW - Humboldteanisiserung KW - Lateinamerika KW - Weltbürger KW - Wissenstypen Humboldts Y1 - 2003 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-opus-34948 SN - 2568-3543 SN - 1617-5239 VL - IV IS - 6 SP - 41 EP - 66 PB - Universitätsverlag Potsdam CY - Potsdam ER - TY - JOUR A1 - Zeilinger, Gabriel T1 - Der süddeutsche Städtekrieg 1449/50 BT - Fehdeorganisation und Kriegsalltag, soziale Verfasstheiten und die 'Ökonomie' des Krieges in einem Großkonflikt des 15.

T1 - Rapid evolution drives ecological dynamics in a predator-prey system N2 - Ecological and evolutionary dynamics can occur on similar timescales. However, theoretical predictions of how rapid evolution can affect ecological dynamics are inconclusive and often depend on untested model assumptions. Here we report that rapid prey evolution in response to oscillating predator density affects predator-prey (rotifer-algal) cycles in laboratory microcosms. Our experiments tested explicit predictions from a model for our system that allows prey evolution. We verified the predicted existence of an evolutionary tradeoff between algal competitive ability and defence against consumption, and examined its effects on cycle dynamics by manipulating the evolutionary potential of the prey population. Single-clone algal cultures (lacking genetic variability) produced short cycle periods and typical quarter-period phase lags between prey and predator densities, whereas multi-clonal (genetically variable) algal cultures produced long cycles with prey and predator densities nearly out of phase, exactly as predicted. These results confirm that prey evolution can substantially alter predator-prey dynamics, and therefore that attempts to understand population oscillations in nature cannot neglect potential effects from ongoing rapid evolution.

T1 - Disentangling microlensing and differential extinction in the double QSO HE 0512-3329 N2 - We present the first separate spectra of both components of the small-separation double QSO HE 0512-3329 obtained with HST/STIS in the optical and near UV. The similarities especially of the emission line profiles and redshifts strongly suggest that this system really consists of two lensed images of one and the same source. The emission line flux ratios are assumed to be unaffected by microlensing and are used to study the differential extinction effects caused by the lensing galaxy. Fits of empirical laws show that the extinction properties seem to be different on both lines of sight. With our new results, HE 0512-3329 becomes one of the few extragalactic systems which show the 2175 Å absorption feature, although the detection is only marginal. We then correct the continuum flux ratio for extinction to obtain the differential microlensing signal. Since this may still be significantly affected by variability and time-delay effects, no detailled analysis of the microlensing is possible at the moment. This is the first time that differential extinction and microlensing could be separated unambiguously. We show that, at least in HE 0512-3329, both effects contribute significantly to the spectral differences and one cannot be analysed without taking into account the other. For lens modelling purposes, the flux ratios can only be used after correcting for both effects.

A1 - Meisenheimer, Klaus T1 - The evolution of faint AGN between z similar or equal to 1 and z similar or equal to 5 from the COMBO-17 survey N2 - We present a determination of the optical/UV AGN luminosity function and its evolution, based on a large sample of faint (R < 24) QSOs identified in the COMBO-17 survey. Using multi-band photometry in 17 filters within 350 nm <~ lambdaobs <~ 930 nm, we could simultaneously determine photometric redshifts with an accuracy of sigmaz <0.03 and obtain spectral energy distributions. The redshift range covered by the sample is 1.2 < z < 4.8, which implies that even at z =~ 3, the sample reaches below luminosities corresponding to MB = -23, conventionally employed to distinguish between Seyfert galaxies and quasars. We clearly detect a broad plateau-like maximum of quasar activity around z =~ 2 and map out the smooth turnover between z =~ 1 and z =~ 4. The shape of the LF is characterised by some mild curvature, but no sharp ``break'' is present within the range of luminosities covered. Using only the COMBO-17 data, the evolving LF can be adequately described by either a pure density evolution (PDE) or a pure luminosity evolution (PLE) model. However, the absence of a strong L*-like feature in the shape of the LF inhibits a robust distinction between these modes. We present a robust estimate for the integrated UV luminosity generation by AGN as a function of redshift. We find that the LF continues to rise even at the lowest luminosities probed by our survey, but that the slope is sufficiently shallow that the contribution of low-luminosity AGN to the UV luminosity density is negligible. Although our sample reaches much fainter flux levels than previous data sets, our results on space densities and LF slopes are completely consistent with extrapolations from recent major surveys such as SDSS and 2QZ.

T1 - Integral-field spectrophotometry of the quadruple QSO HE 0435-1223 : Evidence for microlensing N2 - We present the first spatially resolved spectroscopic observations of the recently discovered quadruple QSO and gravitational lens HE 0435-1223. Using the Potsdam Multi-Aperture Spectrophotometer (PMAS), we show that all four QSO components have very similar but not identical spectra. In particular, the spectral slopes of components A, B, and D are indistinguishable, implying that extinction due to dust plays no major role in the lensing galaxy. While also the emission line profiles are identical within the error bars, as expected from lensing, the equivalent widths show significant differences between components. Most likely, microlensing is responsible for this phenomenon. This is also consistent with the fact that component D, which shows the highest relative continuum level, has brightened by 0.07 mag since Dec. 2001. We find that the emission line flux ratios between the components are in better agreement with simple lens models than broad band or continuum measurements, but that the discrepancies between model and data are still unacceptably large. Finally, we present a detection of the lensing galaxy, although this is close to the limits of the data. Comparing with a model galaxy spectrum, we obtain a redshift estimate of zlens=0.44+/- 0.02.

This is a discussion of the applicability to the phytoplankton of the concepts of 'Plant Functional Types' (PFTs) and 'Functional Diversity' (FD), which originated in terrestrial plant ecology. 2. Functional traits driving the performance of phytoplankton species reflect important processes such as growth, sedimentation, grazing losses and nutrient acquisition. 3. This paper presents an objective, mathematical way of assigning PFTs and measuring FD. Ecologists can use this new approach to investigate general hypotheses (e.g. the intermediate disturbance hypothesis (IDH), the insurance hypothesis and synchronicity phenomena), since, for example, in its original formulation the IDH makes its predictions based on FD rather than species diversity.
