On the occasion of the anniversary of C.A. Clerck's book "Swedish spiders" the paper deals with the beginnings of spider taxonomy, Clerck's life (1709-1765) and work, and P. Bonnet's successful campaign for the validation of species names given by Clerck.
1795 erschien ein Werk unter dem Titel "Sur la Decouverte du Rapport Constant, entre I'apparition ou la disparition, le travail ou le non travail, le plus ou le moins d'etendue des toiles ou des fils d'attache des Araignees des differentes especes; et les Variations AthmospMriques du beau temps a la pluye, du sec a I'humide, mais principalement du chaud - au - froid, & de la gelee a glace au veritable digel: par le Citoyen QuatremereD'lsjonval". Das Buch, aber auch seine Entstehungsgeschichte und das bewegte Leben des Autors schienen es mir wert zu sein, 200 Jahre nach Erscheinen einige Worte darüber zu verlieren. Dabei stütze ich mich auf die Übersetzung ins Deutsche (QUATREMÈRE-D'ISJONVAL 1799).
19th European Colloquium of Arachnology : Århus, Dänemark, 17. - 22. Juli 2000 ; ein Bericht
(2000)
The first rhinoceros of the post-roman era reached Europe in 1513. Albrecht DÜRER, who had not seen the animal himself, made a woodcut that contained several odd features. This woodcut determined the appearance of rhinoceroses for the next two centuries. - The first reports on the food of Eresus sp., citing tiger beetles and dung-beetles as principal prey items, had a somewhat similar fate, i. e. they were accepted as facts for more than half a century. - The present study, performed in Valais, Switzerland, shows E. cinnaberinus to have a much broader prey spectrum: Beetles, half of them carabids, constituted 42 %, ants 36 %, other insects 17 %; 3 % were made up by arthropods other than insects. No tiger beetles or dung-beetles were found. - It can be concluded that even numerous repetitions in textbooks may not reflect the true story.
Long-range angular correlations on the near and away side in p–Pb collisions at √sNN=5.02 TeV
(2013)
Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5<pT,assoc<pT,trig<4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and pT bins, and the widths show no significant evolution with event multiplicity or pT. These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge.
