Cicurina japonica (Araneae: Dictynidae) - eine nach Mitteleuropa eingeschleppte Kräuselspinnenart
(2005)
Die ersten beiden Nachweise der ursprünglich ostasiatisch verbreiteten Kräuselspinnen-Art Cicurina japonica (Simon, 1886) für Europa werden vorgestellt. Die umfangreichen Funde im Areal des ehemaligen Güterbahnhofes der Deutschen Bundesbahnen (DB) in Basel erlauben ansatzweise eine ökologische Charakterisierung der Art.
This study analyses the role of the Romanian language in Christian Hallers novel Die verschluckte Musik (2008). The Romanian words are linked to the content and symbolical context, and also to intimacy or strangeness. Single words and expressions are connected to memories and rituals. For the family residing in Bucharest they are everyday elements. By migration they become cultural artefacts, are included in family stories. In the new home country Switzerland, the Romanian language is an element of intimacy. The language is also a method of exclusion and dissociation. Ruth, the first-person narratorʼs mother, is excluded in Bucharest until she learns the national language. In the Swiss environment the already familiar Romanian language is for Ruth a method of dissociation. For the first-person narrator, the few Romanian words are details connected to gastronomic culture which distinguish him from the Swiss environment. While travelling through Bucharest, the Romanian language becomes a method of exclusion, it is connected to an area that was not attainable for a long period. His journey updates the language for him.
Since 2013, the Swiss Federal Intelligence Service (FIS) has warned of a heightened threat emanating from jihadi terrorism in Switzerland. According to FIS’s assessment, the threat has continuously risen since then and reached a new high in 2016. This is a new situation for a country that has, since the two attacks conducted by Palestinian groups targeting an El Al airplane in Kloten in 1969 and the bombing of a Swissair machine in 1970, remained largely unscathed by terrorism. This has remained true even in the decade after 9/11 when a wave of jihadi terrorism inspired and often directed by al-Qaeda struck urban centers in Europe and elsewhere on multiple occasions...
This study investigated laypersons’ perception of invasive alien plant species (IAPS) and attitudes towards their management with the help of a written questionnaire in the cities of Zurich, Geneva, and Lugano, Switzerland. Survey participants (n = 720) judged attractiveness from certain species on visual contact (eight IAPS were shown as photographs). Trachycarpus fortunei and Ludwigia grandiflora were liked most, while Ambrosia artemisiifolia was clearly disliked most. With the exception of Trachycarpus fortunei, all plant species were perceived as rather ordinary, familiar and native to Switzerland, and feelings of ordinariness, familiarity and nativeness were positively correlated. Few participants could correctly identify the species depicted. Knowledge of an IAPS (ability to identify it) and desire to have it around were negatively correlated. Participants agreed most with the eradication of IAPS that cause serious costs and problems. However, people were rather unwilling to remove Buddleja davidii, Solidago canadensis, and Trachycarpus fortunei which are already widely established ornamentals in settlement areas or gardens. Overall, willingness to remove an IAPS and to report it to the authorities decreased with increasing desirability (and thus beauty) of a species.
Pitfall traps were positioned for the investigation of the spider fauna at the northern and southern slopes of three mountain ridges (Chilchberg, Riedberg, and Buechenberg, municipalities Nunningen and Zullwil, canton Solothurn, Switzerland) within the Swiss Jura Mountains. The temperature in the upper litter was measured at three hour intervals. Independent of the weather more or less clear differences between northern and southern slopes could be observed. Maximum day temperature fluctuations of 15.8 °C were measured. There were no significant differences in spider communities based on quantitative comparison methods. However, a qualitative analysis showed major differences in species composition. More than 50% of all species per investigation area showed clear preferences for the northern or the southern slope, with more then two thirds of the individuals only found on either the north or south slopes.
In the ”Checklist of the spiders of Central Europe” 945 species are listed for Switzerland. During the last few years numerous species have been found which represent new records for Switzerland and that, at least partly, have already been published. This 4th appendix to the catalogue of Swiss spiders presents fourteen species recorded for the first time in Switzerland: Carniella brignolii Thaler & Steinberger, 1988, Theridion cinereum Thorell, 1875, Diplocephalus foraminifer (O. P.-Cambridge, 1875), Panamomops affinis Miller & Kratochvíl, 1939, Troxochrota scabra Kulczyński, 1894, Pardosa fulvipes (Collett, 1876), P. sphagnicola (Dahl, 1908), Hahnia microphthalma Snazell & Duffey, 1980, Archaeodictyna consecuta (O. P.-Cambridge, 1872), Brommella falcigera (Balogh, 1935), Cheiracanthium campestre Lohmander, 1944, Drassodex drescoi Hervé, Roberts & Murphy, 2009, Thanatus firmetorum Muster & Thaler, 2003 and Xysticus viduus Kulczyński, 1898. Thirteen further species are presented that were already published elsewhere. The current number of species in Switzerland is thus 972. As special curiosities, five species are presented that will not yet be entered into the checklist but nevertheless may happen to be found in human surroundings.
Objectives: This study identified potential general influencing factors for a mathematical prediction of implant stability quotient (ISQ) values in clinical practice.
Methods: We collected the ISQ values of 557 implants from 2 different brands (SICace and Osstem) placed by 2 surgeons in 336 patients. Surgeon 1 placed 329 SICace implants, and surgeon 2 placed 113 SICace implants and 115 Osstem implants. ISQ measurements were taken at T1 (immediately after implant placement) and T2 (before dental restoration). A multivariate linear regression model was used to analyze the influence of the following 11 candidate factors for stability prediction: sex, age, maxillary/mandibular location, bone type, immediate/delayed implantation, bone grafting, insertion torque, I-stage or II-stage healing pattern, implant diameter, implant length and T1-T2 time interval.
Results: The need for bone grafting as a predictor significantly influenced ISQ values in all three groups at T1 (weight coefficients ranging from -4 to -5). In contrast, implant diameter consistently influenced the ISQ values in all three groups at T2 (weight coefficients ranging from 3.4 to 4.2). Other factors, such as sex, age, I/II-stage implantation and bone type, did not significantly influence ISQ values at T2, and implant length did not significantly influence ISQ values at T1 or T2.
Conclusions: These findings provide a rational basis for mathematical models to quantitatively predict the ISQ values of implants in clinical practice.
During verifications of museum material for the Catalogue of the Palaearctic Coleoptera, the type specimen of Hylobius huguenini Reitter, 1891 conserved in the Hungarian National Museum was examined. The type specimen had been found by Gustav Huguenin in the Emmental region in Switzerland. The species was never found again and remained therefore mysterious. After the examination of the type specimen, it became clear that Hylobius huguenini belongs to the American genus Heilipodus Kuschel, 1955 (comb. nov.), and there it ranks as a good species next to Heilipodus goeldii sp. nov., described here, and H. polyspilus (Pascoe, 1889), both from Brazil. The type specimens of Heilipodus goeldii sp. nov. were found in the Emil August Göldi-collection in the Natural History Museum of the Burgergemeinde Bern.
