Rickettsiae are obligately intracellular bacteria transmitted by arthropod vectors. The ecology of Rickettsia species has not been investigated in detail, but small mammals are considered to play a role as reservoirs. Aim of this study was to monitor rickettsiae in wild small mammals over a period of five years in four federal states of Germany. Initial screening of ear pinna tissues of 3939 animals by Pan-Rick real-time PCR targeting the citrate synthase (gltA) gene revealed 296 rodents of seven species and 19 shrews of two species positive for rickettsial DNA. Outer membrane protein gene (ompB, ompAIV) PCRs based typing resulted in the identification of three species: Rickettsia helvetica (90.9%) was found as the dominantly occurring species in the four investigated federal states, but Rickettsia felis (7.8%) and Rickettsia raoultii (1.3%) were also detected. The prevalence of Rickettsia spp. in rodents of the genus Apodemus was found to be higher (approximately 14%) than in all other rodent and shrew species at all investigated sites. General linear mixed model analyses indicated that heavier (older) individuals of yellow-necked mice and male common voles seem to contain more often rickettsial DNA than younger ones. Furthermore, rodents generally collected in forests in summer and autumn more often carried rickettsial DNA. In conclusion, this study indicated a high prevalence of R. helvetica in small mammal populations and suggests an age-dependent increase of the DNA prevalence in some of the species and in animals originating from forest habitats. The finding of R. helvetica and R. felis DNA in multiple small mammal species may indicate frequent trans-species transmission by feeding of vectors on different species. Further investigations should target the reason for the discrepancy between the high rickettsial DNA prevalence in rodents and the so far almost absence of clinical apparent human infections.

Uncovering the link between host and virus dynamics can help to prevent human PUUV infections in the future. Bank voles were live trapped three times a year in 2010–2013 in three woodland plots in each of four regions in Germany. Bank vole population density was estimated and blood samples collected to detect PUUV specific antibodies. Results We demonstrated that fluctuation of PUUV seroprevalence is dependent not only on multi-annual but also on seasonal dynamics of rodent host abundance. Moreover, PUUV infection might affect host fitness, because seropositive individuals survived better from spring to summer than uninfected bank voles. Individual space use was independent of PUUV infections.

Diese Sprachpraxis etablierte eine einseitige Forschungsperspektive, die sich ihrem Gegenstand aus dem Täter-Opfer-Paradigma heraus näherte. In der jüngsten Zeit unternahm man jedoch Versuche, diese Perspektive zu brechen, indem man das Ghetto-Phänomen anhand solcher Untersuchungskategorien wie ‚Lebenswelt’, ‚Erfahrung’ und ‚Konstruktion von Raum’ sowie ‚Ambivalenz von Raum und Grenze’ befragte. Das stetig wachsende Interesse an begrifflicher Reflexion über den Sprachkörper ‚Ghetto’ und an den von ihm bezeichneten historischen Phänomenen samt ihren Widerspiegelungen in der Literatur und bildenden Künsten ist ein starkes Indiz für einen Wandel der Sehgewohnheiten innerhalb der Forschung. In Folge der vorgenommenen Differenzierungen entwickeln sich neue Fragestellungen und Ansätze, die die Reduktion der Wissenschaft von der jüdischen Geschichte und Kultur auf die Kategorien von ‚Unterdrückung’ und ‚Verfolgung’ zu überwinden erlauben. Mit dem vorliegenden Heft möchten wir einen Beitrag zu diesem Fachgespräch leisten. Die hier abgedruckten Beiträge lassen sich in zwei Kategorien unterteilen. Zum einen sind es explizite Befragungen des Ghetto-Begriffs im Dienste wissenschaftsgeschichtlicher Reflexionen oder neuer Verfahren zur Erforschung historischer Erscheinungsformen des Ghettos. Hierzu gehören die Artikel von Kristiane Gerhardt, Svenja Bethke und Hanna Schmidt Holländer sowie Birgitt Wagner. In ihren historiographiegeschichtlich bzw. methodologisch orientierten Erörterungen zeigen die Autorinnen die normative Dimension und die daraus resultierende semantische Wandelbarkeit des Ghetto-Begriffs samt ihren Konsequenzen für die Forschungspraxis. In die zweite Kategorie lassen sich wiederum phänomenologisch interessierte Untersuchungen einreihen, die entweder geschichtliche Fallstudien oder Betrachtungen literarischer Repräsentationen des Themas sind. Hierzu gehören die Beiträge von Luca Baraldi, Stratos N. Dordanas und Vaios Kalogrias, Tanja Kinzel, Francisca Solomon und Elvira Grözinger. N2 - Under recourse of two historical forms of ‘ghetto’ – a Jewish quarter in the Early Modern Era and the National Socialist ghetto – the term ‘ghetto’ became stylised as a symbol of yoke and persecution. Through everyday language this established itself as a one sided research perspective, which has the purpose of using the perpetrator-victim-paradigm. Recently people have tried to break this perspective, by analysing the ghetto phenomenon with the use of research categories, for example, ‘living environment’, ‘experience’, ‘construction and area’ as well as ‘ambivalence to the area and border’. The continuing interest in the conceptual reflection of the word ‘ghetto’, including its historical phenomenon together with its reflection in literature and the educational arts, is a strong indication of a change in the viewing habits within this field of research. Following the conducted differentiation, new questions and approaches developed which allowed one to overcome the reduction of this academic field from Jewish history and culture into the category of ‘oppression’ and ‘persecution’. By using this periodical we would like to contribute to this field of expertise. The articles, which are printed here, can be divided into two categories. Firstly there are explicit questions regarding the concept of the ghetto relating to academic historical reflections or new procedures into the research of the historical manifestation of the ghetto. The articles from Kristiane Gerhardt, Svenja Bethke and Hanna Schmidt Holländer as well as Birgitt Wagner belong to this group. In their historiography, or rather methodological orientated discussions, the authors show the normative dimension and the resulting semantic change of the ‘ghetto’ concept together with their consequences in the field of research. In the second category, on the other hand, the phenomenological interested research can be indexed as either historical case studies or observations of literary representations of the topics. The articles from Luca Baraldi, Stratos N. Dordanas and Vaios Kalogrias, Tanja Kinzel, Francisca Solomon and Elvira Grözinger belong to this group.

The sensor provides continuous soil moisture data, averaged over several hectares and tens of decimeters in depth. However, the signal still may contain unidentified features of hydrological processes, and many calibration datasets are often required in order to find reliable relations between neutron intensity and water dynamics. Recent insights into environmental neutrons accurately described the spatial sensitivity of the sensor and thus allowed one to quantify the contribution of individual sample locations to the CRNS signal. Consequently, data points of calibration and validation datasets are suggested to be averaged using a more physically based weighting approach. In this work, a revised sensitivity function is used to calculate weighted averages of point data. The function is different from the simple exponential convention by the extraordinary sensitivity to the first few meters around the probe, and by dependencies on air pressure, air humidity, soil moisture, and vegetation. The approach is extensively tested at six distinct monitoring sites: two sites with multiple calibration datasets and four sites with continuous time series datasets. In all cases, the revised averaging method improved the performance of the CRNS products. The revised approach further helped to reveal hidden hydrological processes which otherwise remained unexplained in the data or were lost in the process of overcalibration. The presented weighting approach increases the overall accuracy of CRNS products and will have an impact on all their applications in agriculture, hydrology, and modeling.
