1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Jonatan Uusitalo; [2023-08-17]
   Keywords : ;

   Abstract : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

3. 2. Drivers of sea level variability using neural networks

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Linn Carlstedt; [2023-05-10]
   Keywords : ;

   Abstract : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

4. 3. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sara Rognås; [2023]
   Keywords : aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

   Abstract : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. READ MORE

5. 4. Effects of climate, soil, and forest structure on specific leaf area of understorey foundation plants

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Sashank Khaniya; [2023]
   Keywords : Specific leaf area; understorey vegetation; foundation species; forest structure; climate change;

   Abstract : Forest overstorey's interaction with understorey vegetation is a crucial aspect that impacts the biodiversity and resilience of forest ecosystems. Particularly, the influence of the overstorey on the specific leaf area (SLA) in understorey plants remains poorly understood. READ MORE

6. 5. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Nils Helge Havertz; [2023]
   Keywords : Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

   Abstract : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.
