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.}, language = {en} } @article{ReilRosenfeldImholtetal.2017, author = {Reil, Daniela and Rosenfeld, Ulrike and Imholt, Christian and Schmidt, Sabrina and Ulrich, Rainer G. and Eccard, Jana and Jacob, Jens}, title = {Puumala hantavirus infections in bank vole populations}, series = {BMC ecology}, volume = {17}, journal = {BMC ecology}, publisher = {BioMed Central}, address = {London}, issn = {1472-6785}, doi = {10.1186/s12898-017-0118-z}, pages = {13}, year = {2017}, abstract = {Background In Europe, bank voles (Myodes glareolus) are widely distributed and can transmit Puumala virus (PUUV) to humans, which causes a mild to moderate form of haemorrhagic fever with renal syndrome, called nephropathia epidemica. 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. Conclusions Our study provides robust estimations of relevant patterns and processes of the dynamics of PUUV and its rodent host in Central Europe, which are highly important for the future development of predictive models for human hantavirus infection risk}, language = {en} } @book{SchmidtUlrichBuechneretal.2024, author = {Schmidt, Thorsten Ingo and Ulrich, Peter and B{\"u}chner, Christiane and Franzke, Jochen and Jann, Werner and Bauer, Hartmut and Wagner, Dieter and Br{\"u}ning, Christoph and Bickenbach, Christian and Kuhlmann, Sabine and Peters, Niklas and Reichard, Christoph and Tessmann, Jens and Maaß, Christian and Kern, Kristine and Kochsk{\"a}mper, Elisa and Gailing, Ludger and Krzymuski, Marcin}, title = {Kommunalwissenschaften an der Universit{\"a}t Potsdam}, series = {KWI-Schriften}, journal = {KWI-Schriften}, number = {15}, editor = {Schmidt, Thorsten Ingo and Bickenbach, Christian and Gronewold, Ulfert and Kuhlmann, Sabine and Ulrich, Peter}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-581-1}, issn = {1867-951X}, doi = {10.25932/publishup-63618}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-636180}, publisher = {Universit{\"a}t Potsdam}, pages = {124}, year = {2024}, abstract = {Zum dreißigj{\"a}hrigen Bestehen des Kommunalwissenschaftlichen Instituts an der Universit{\"a}t Potsdam vereint dieser Jubil{\"a}umsband kurze Aufs{\"a}tze von ehemaligen und aktuellen Vorstandsmitgliedern, von Ehrenmitgliedern des Vorstands, langj{\"a}hrigen wissenschaftlichen Mitarbeitern des Instituts und aktuellen wissenschaftlichen Kooperationspartnern.

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.}, language = {en} }
