1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN
University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskapAbstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

2. Forest regeneration and edge effects : an ecophysiological analysis after gap-cutting
University essay from SLU/Dept. of Forest Ecology and ManagementAbstract : As continuous cover forestry is an ongoing topic in todays forest debate, questions are raised about eventual issues connected to the management. It is known that seedling performance can be poor near the edge of harvested areas, and around retained trees. This is a critical issue in transitioning toward continuous cover forestry. READ MORE

3. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. READ MORE

4. Mercury in Fossil Leaves as a Proxy for Tracking Large Igneous Province Volcanism
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : During some mass extinctions, usually minor, world oceans also underwent anoxic to euxinic conditions, events called Oceanic anoxic events (OAEs). Such an event unfolded during the Toarcian (∼183 Ma), called the T-OAE which is suggested to have been caused by Karoo-Ferrar Large Igneous Province (LIP) volcanism. READ MORE

5. The evaluation of preparation techniques for the measurements of hydrogen isotope ratios in ecology
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The stable isotope ratio of non-exchangeable hydrogen (δ2Hn) emerged as a promising new tool for source attribution in aquatic ecology, which can better discriminate between the organic matter sources. However, determining the absolute isotopic values is problematic due to the functional groups with hydrogen (H) that can easily exchange with the ambient water. READ MORE
