1. 1. Influence of structural complexity of the Rumperöd forest on evapotranspiration

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Madeleine Durdek; [2023]
   Keywords : Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

   Abstract : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. READ MORE

3. 2. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Mattias Sundin; [2023]
   Keywords : Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

   Abstract : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. READ MORE

4. 3. Heterobasidion spp presence in young pine plantations in southern Sweden

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Sarah Louise Gore; [2023]
   Keywords : Heterobasidion; Scots pine; Pinus Sylvestris; Sweden;

   Abstract : Heterobasidion species cause great economic loss the forest industry in the northern hemisphere. The spread of infection takes two forms, the first is an airborne infection and the second is a vegetative infection from infected root to healthy root. Much research has been done concerning the Heterobasidion pathogen. READ MORE

5. 4. Competition between managed honeybees and wild bumblebees - Quantifying dietary overlap in semi-natural grasslands

   University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : Emma Rosberg; [2023]
   Keywords : Earth and Environmental Sciences;

   Abstract : The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. READ MORE

6. 5. Day or night? Testing thermal imaging technology for estimating ungulate population densities in southern Sweden

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Julia Nowak; [2023]
   Keywords : monitoring; ungulates; thermal imaging; population density; distance sampling; Dama dama;

   Abstract : To be able to make a proper judgement and choose the best management or conservation solution when working with populations of wild ungulates or any other wildlife, it is important to obtain good estimates of population densities. Inventing or improving wild animal monitoring methods is a key to protect what may be endangered or to avoid human-wildlife conflicts. READ MORE
