    Description / Table of Contents: Moss-microbe associations are often characterised by syntrophic interactions between the microorganisms and their hosts, but the structure of the microbial consortia and their role in peatland development remain unknown. In order to study microbial communities of dominant peatland mosses, Sphagnum and brown mosses, and the respective environmental drivers, four study sites representing different successional stages of natural northern peatlands were chosen on a large geographical scale: two brown moss-dominated, circumneutral peatlands from the Arctic and two Sphagnum-dominated, acidic peat bogs from subarctic and temperate zones. The family Acetobacteraceae represented the dominant bacterial taxon of Sphagnum mosses from various geographical origins and displayed an integral part of the moss core community. This core community was shared among all investigated bryophytes and consisted of few but highly abundant prokaryotes, of which many appear as endophytes of Sphagnum mosses. Moreover, brown mosses and Sphagnum mosses represent habitats for archaea which were not studied in association with peatland mosses so far. Euryarchaeota that are capable of methane production (methanogens) displayed the majority of the moss-associated archaeal communities. Moss-associated methanogenesis was detected for the first time, but it was mostly negligible under laboratory conditions. Contrarily, substantial moss-associated methane oxidation was measured on both, brown mosses and Sphagnum mosses, supporting that methanotrophic bacteria as part of the moss microbiome may contribute to the reduction of methane emissions from pristine and rewetted peatlands of the northern hemisphere. Among the investigated abiotic and biotic environmental parameters, the peatland type and the host moss taxon were identified to have a major impact on the structure of moss-associated bacterial communities, contrarily to archaeal communities whose structures were similar among the investigated bryophytes. For the first time it was shown that different bog development stages harbour distinct bacterial communities, while at the same time a small core community is shared among all investigated bryophytes independent of geography and peatland type. The present thesis displays the first large-scale, systematic assessment of bacterial and archaeal communities associated both with brown mosses and Sphagnum mosses. It suggests that some host-specific moss taxa have the potential to play a key role in host moss establishment and peatland development.
    Description / Table of Contents: Während die Beziehungen zwischen Moosen und den mit ihnen assoziierten Mikroorganismen oft durch syntrophische Wechselwirkungen charakterisiert sind, ist die Struktur der Moos-assoziierten mikrobiellen Gemeinschaften sowie deren Rolle bei der Entstehung von Mooren weitgehend unbekannt. Die vorliegende Arbeit befasst sich mit mikrobiellen Gemeinschaften, die mit Moosen nördlicher, naturnaher Moore assoziiert sind, sowie mit den Umweltfaktoren, die sie beeinflussen. Entlang eines groß angelegten geographischen Gradienten, der von der Hocharktis bis zur gemäßigten Klimazone reicht, wurden vier naturbelassene Moore als Probenstandorte ausgesucht, die stellvertretend für verschiedene Stadien der Moorentwicklung stehen: zwei Braunmoos-dominierte Niedermoore mit nahezu neutralem pH-Wert sowie zwei Sphagnum-dominierte Torfmoore mit saurem pH-Wert. Die Ergebnisse der vorliegenden Arbeit machen deutlich, dass die zu den Bakterien zählenden Acetobacteraceae das vorherrschende mikrobielle Taxon der Sphagnum-Moose gleich welchen geographischen Ursprungs darstellen und insbesondere innerhalb des Wirtsmoosgewebes dominieren. Gleichzeitig gehörten die Acetobacteraceae zum wesentlichen Bestandteil der mikrobiellen Kerngemeinschaft aller untersuchten Moose, die sich aus einigen wenigen Arten, dafür zahlreich vorkommenden Prokaryoten zusammensetzt. Die vorliegende Arbeit zeigt zudem erstmals, dass sowohl Braunmoose als auch Torfmoose ein Habitat für Archaeen darstellen. Die Mehrheit der Moos-assoziierten Archaeen gehörte dabei zu den methanbildenden Gruppen, wenngleich die metabolischen Aktivitätsraten unter Laborbedingungen meistens kaum messbar waren. Im Gegensatz hierzu konnte die Bakterien-vermittelte Methanoxidation sowohl an Braunmoosen als auch an Sphagnum-Moosen gemessen werden. Dies zeigt eindrucksvoll, dass Moos-assoziierte Bakterien potenziell zur Minderung von Methanemissionen aus nördlichen, aber auch wiedervernässten Mooren beitragen können. Ein weiteres wichtiges Resultat der vorliegenden Arbeit ist die Bedeutung des Moortyps (Niedermoor oder Torfmoor), aber auch der Wirtsmoosart selbst für die Struktur der Moos-assoziierten Bakteriengemeinschaften, während die archaeellen Gemeinschaftsstrukturen weder vom Moortyp noch von der Wirtsmoosart beeinflusst wurden und sich insgesamt deutlich ähnlicher waren als die der Bakterien. Darüber hinaus konnte erstmalig gezeigt werden, dass sich die bakteriellen Gemeinschaften innerhalb der unterschiedlichen Moorsukzessionsstadien zwar ganz erheblich voneinander unterscheiden, ein kleiner Teil der Bakterien dennoch Kerngemeinschaften bilden, die mit allen untersuchten Moosarten assoziiert waren. Bei der hier präsentierten Arbeit handelt es sich um die erste systematische Studie, die sich auf einer großen geographischen Skala mit den bakteriellen und archaeellen Gemeinschaften von Braunmoosen und Torfmoosen aus naturbelassenen nördlichen Mooren befasst. Die vorliegenden Ergebnisse machen deutlich, dass die untersuchten Moose ein ganz spezifisches mikrobielles Konsortium beherbergen, welches mutmaßlich eine Schlüsselrolle bei der Etablierung der Wirtspflanzen am Anfang der Moorentwicklung spielt und darüber hinaus das Potential hat, die charakteristischen Eigenschaften von Mooren sowie deren weitere Entwicklung zu prägen.

    Description / Table of Contents: With increasing urbanization, a well-functioning transport infrastructure that takes into account the needs of the society is becoming more and more important. In particular, a high proportion of motorized traffic can cause far-reaching problems that affect large parts of the urban population, such as traffic congestion or increased air pollution. To counteract this trend, an optimized distribution of traffic flows could improve the situation from a societal perspective. Since most routing decisions are made based on digital maps before the journey starts, clear and intuitive visualization is crucial for conveying the cartographic information to the traveler. While most existing services typically provide the most efficient routing options in terms of travel time, newer approaches attempt to guide drivers to societally favorable routes. These take into account societally relevant factors, which are referred to as scenarios in this thesis, and include environmental issues such as traffic congestion or air pollution. However, since such a societally favorable route is not necessarily efficient for the individual traveler, it is important to convince the traveler to choose a seemingly less efficient route. For this purpose, an automatic method for visualizing route maps is developed, which calculates societally favorable routes, and communicates them visually to the end user in such a way that the user would prefer to use them. For this communication, different visual variables of cartography are used, whose usage is adapted to the different scenarios and controlled by scenario-specific thresholds. Based on the goal of dynamic distribution of traffic flows, the proposed method recommends routes that are not necessarily the shortest or fastest, but rather those that seek to avoid unfavorable or hazardous paths or areas. The proposed design variants of route maps use a large variety of symbolization techniques; including classic visual variables of cartography such as color, size or pattern, but also more abstract methods that use cartographic generalization techniques.
    Description / Table of Contents: Mit zunehmender Verstädterung gewinnt eine gut funktionierende Verkehrsinfrastruktur, die den Bedürfnissen der Gesellschaft Rechnung trägt, immer mehr an Bedeutung. Insbesondere ein hoher Anteil an motorisiertem Verkehr kann weitreichende Probleme verursachen, die große Teile der Stadtbevölkerung betreffen, wie z.B. Verkehrsstaus oder erhöhte Luftverschmutzung. Um dieser Entwicklung entgegenzuwirken, könnte eine optimierte Verteilung der Verkehrsströme die Situation für die Gemeinschaft verbessern. Da die meisten Routing-Entscheidungen vor Reiseantritt auf der Grundlage digitaler Karten getroffen werden, ist eine klare und intuitive Visualisierung entscheidend für die Vermittlung kartografischer Informationen an den Reisenden. Während die meisten bestehenden Dienste in der Regel die effizientesten Routing-Optionen im Hinblick auf die Reisezeit bieten, versuchen neuere Ansätze, die Fahrer auf gesellschaftlich vorteilhafte Routen zu leiten. Diese berücksichtigen gesellschaftlich relevante Faktoren, die in dieser Arbeit als Szenarien bezeichnet werden. Darunter fallen Umweltprobleme wie Verkehrsstaus oder Luftverschmutzung. Da eine solche gesellschaftlich vorteilhafte Route für den einzelnen Reisenden jedoch nicht zwangsläufig effizient ist, ist es wichtig, den Reisenden davon zu überzeugen, eine scheinbar weniger effiziente Route zu wählen. Dazu wird im Rahmen der Arbeit ein automatisches Verfahren zur Visualisierung von Routenkarten entwickelt, welches gesellschaftlich vorteilhafte Routen berechnet und diese so visuell dem Endnutzer kommuniziert, dass dieser sie bevorzugt nutzen möchte. Für diese Kommunikation kommen verschiedene visuelle Variablen der Kartographie zum Einsatz, deren Verwendung auf die verschiedenen Szenarien angepasst sind und über Szenario-spezifische Schwellwerte gesteuert werden. Basierend auf dem Ziel einer dynamischen Verteilung der Verkehrsströme empfiehlt die vorgeschlagene Methode Routen, die nicht unbedingt die kürzesten oder schnellsten sind, sondern vielmehr solche Routen, die ungünstige oder gefährliche Wege oder Bereiche zu vermeiden versuchen. Die vorgeschlagenen Designvarianten von Routenkarten nutzen eine Vielzahl von Symbolisierungstechniken; darunter klassische, visuelle Variablen der Kartographie wie Farbe, Größe oder Muster, aber auch abstraktere Methoden, die kartographische Generalisierungstechniken verwenden.
