2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

3. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE

4. Evaluating drought impacts on ecosystem water use efficiency of three different boreal forest sites
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : European boreal forests are the biomes most affected by climate change. For example, extreme weather events such as droughts are expected to become more frequent and severe. Especially in the summer months, droughts can drastically impact the carbon and water exchanges of boreal forests. READ MORE

5. Legacy effects of spring temperature anomalies on seasonal productivities in northern ecosystems
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Legacy effects of spring temperature anomalies on seasonal productivities in northern ecosystems Direct and lagged effects from spring temperature anomalies for the time-period 2001-2018 have been investigated for northern ecosystems (> 30°N). Three different data sets of Gross Primary Production (GPP) estimates (GOSIF, NIRvGPP and FLUX GPP) have been used in tandem with concurrent climate data to find significant correlations between spring growth and temperature anomalies and subsequent growing seasons.
