Carbon dynamics and greenhouse gas emissions in a tropical dry forest and a pre-alpine Bavarian grassland
DownloadFall 2020
The present thesis contains three studies, all of which follow the main trend of quantification and assessment of carbon dynamics and greenhouse gas emissions. The main objectives of the first study “Dynamics of carbon sequestration in tropical dry forests along two successional gradients under...

Fluvial inorganic carbon cycling across divergently evolving permafrost landscapes (Yukon and Northwest Territories, Canada)
DownloadFall 2019
Across the circumpolar north, rapid warming and intensifying hydrologic cycles are accelerating permafrost thaw and strengthening land-freshwater linkages. Among the most significant implications of this change is the mobilization of large amounts of previously sequestered organic and inorganic...

Growth Characterization and Transcriptomics of Methanotrophic Bacteria as Effected by Carbon and Nitrogen Sources
DownloadFall 2019
While industrial activities have shaped our modern world and lifestyles, one of their many important environmental effects is the significant increase in methane emissions and the resultant atmospheric methane concentrations. A common byproduct of many industries, methane is often burned off as...

Out of the Dark, into the Light? Influence of Wildfire and Thermokarst on Greenhouse Gas Fluxes from Boreal Peat Landscapes near the southern Limit of Permafrost
DownloadFall 2024
Wildfire and permafrost thaw have been common disturbances in the boreal zone for millennia and are now intensified by warming due to human-made climate change. The Taiga Plains ecozone in northwestern Canada is warming at a faster rate than other regions. In this ecozone, permafrost is found at...

Production and detection of polyhydroxybutyrate (PHB) in the alphaproteobacterial methanotroph Methylocystis sp. Rockwell
DownloadSpring 2023
Anthropogenic agricultural and industrial activities have intensified in the past few decades to satisfy the food and energy demands of a rapidly growing human population. The increase in these activities is causing extremely high emission of greenhouse gases which results in global warming and...
