T1  - The influence of above-ground herbivory on the response of Arctic soil methanotrophs to increasing CH4 concentrations and temperatures
JF  - Microorganisms : open access journal
N2  - Rising temperatures in the Arctic affect soil microorganisms, herbivores, and peatland vegetation, thus directly and indirectly influencing microbial CH4 production. It is not currently known how methanotrophs in Arctic peat respond to combined changes in temperature, CH4 concentration, and vegetation. We studied methanotroph responses to temperature and CH4 concentration in peat exposed to herbivory and protected by exclosures. The methanotroph activity was assessed by CH4 oxidation rate measurements using peat soil microcosms and a pure culture of Methylobacter tundripaludum SV96, qPCR, and sequencing of pmoA transcripts. Elevated CH4 concentrations led to higher CH4 oxidation rates both in grazed and exclosed peat soils, but the strongest response was observed in grazed peat soils. Furthermore, the relative transcriptional activities of different methanotroph community members were affected by the CH4 concentrations. While transcriptional responses to low CH4 concentrations were more prevalent in grazed peat soils, responses to high CH4 concentrations were more prevalent in exclosed peat soils. We observed no significant methanotroph responses to increasing temperatures. We conclude that methanotroph communities in these peat soils respond to changes in the CH4 concentration depending on their previous exposure to grazing. This "conditioning " influences which strains will thrive and, therefore, determines the function of the methanotroph community.

N2  - Dieses Sonderheft der Schriftenreihe des Lehrstuhls für Public und Nonprofit Management präsentiert Ergebnisse eines studentischen Beratungsprojekts aus dem Wintersemester 2018/19. Dabei wurde eine Vision für eine digitalisierte öffentliche Verwaltung entworfen. Unter Anwendung von Szenariomethoden wurden Zukunftsszenarien entwickelt und getestet, die sich entweder mit Bürger*innen und Unternehmen als Kund*innen der Verwaltung, den öffentlich Beschäftigen oder der Aufbau- und Ablauforganisation in der Verwaltung beschäftigen.
N2  - This Special Issue of the Chair of Public and Nonprofit Management’s publication series presents results of a student consulting project from the winter semester 2018/19. A vision for a digital public administration has been designed. By using the scenario method, future scenarios have been developed and tested. These scenarios deal either with citizens and businesses as clients of the administration, public employees or organizational structure and internal coordination.
