1. Comparative genomics of Central Arctic Ocean microbiota for observation of Alternative Carbon Fixation Pathways
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : The Central Arctic Ocean is a repository of rich and diverse biota, whose major portion is one of the most important drivers of global biogeochemical cycles, including carbon cycling. In this study, the functional potential of the microbiota to fix carbon with alternative carbon fixation pathways were investigated along with their chemolithotrophic characteristics. READ MORE

2. P-cycling in sub-Arctic lakes – the importance of sediment release and retention
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

3. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. READ MORE

4. Transcriptomic profiling of marine bacteria between development and senescence phases of a phytoplankton bloom
University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Abstract : Bacterioplankton provide important ecosystem functions by carrying out biogeochemical cycling of organic matter. Playing an important role in the microbial loop they help remineralize carbon and nutrients. Bacteria also interact with phytoplankton during phytoplankton blooms. READ MORE

5. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. READ MORE
