1. 1. 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

3. 2. Reviving an 18th Century Dream of Swedish-Grown Tea. Examining the possibilities of growing tea, Camellia sinensis, in Sweden based on climatic crop requirements using GIS

4. 3. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

   University essay from Lunds universitet/Matematisk statistik

   Author : Marcus Gehrmann; [2023]
   Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

   Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

5. 4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Carl Holmquist; [2023]
   Keywords : Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

   Abstract : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. READ MORE
