1. 1. MODELLING THE SMOLT PRODUCTIVITY OF BROWN TROUT (SALMO TRUTTA) IN HAGA Å

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Lukas Almgren; [2023-10-30]
   Keywords : Brown trout; Salmo trutta; Trout habitat score; THS; Haga å; electro-fishing survey;

   Abstract : The brown trout (Salmo trutta) is a facultatively anadromous species, some individuals migrate from the rearing environment in the rivers to the sea while other individuals stay in fresh water. To determine the suitability of a stream for juvenile trout the organization SGBALANST has developed what is called the "Trout habitat score" (THS) model. READ MORE

3. 2. A computational model of metapopulation dynamics and organism-mediated nutrient flow

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Amanda Hansson; [2023-08-07]
   Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

   Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

4. 3. Assessing the accuracy of a spatial model of habitat suitability for Calypso bulbosa

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Michael Doorly; [2023]
   Keywords : Calypso bulbosa; norna; orchid; conservation; Sweden; alpine region; habitat suitability; distribution model; ecology; biodiversity;

   Abstract : Calypso bulbosa is a rare and visually striking orchid that grows in older mesic to moist forests in the northern half of Sweden. C. bulbosa is red listed as a threatened species (Vulnerable, VU) with a reduction in numbers linked to modern forestry practices and exacerbated by the warming climate. READ MORE

5. 4. Future climate suitability of shade trees in cocoa agroforestry systems in West Africa and shade tree diversity’s impact on farm microclimate : A Minor Field Study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Jonna Halonen; [2023]
   Keywords : species distribution modeling; cocoa agroforestry; shade trees; West Africa; microclimate; distributionsmodell; kakaoskogslantbruk; skuggträd; Västafrika; mikroklimat;

   Abstract : Shade trees’ implementation into cocoa agroforestry systems in tropical West Africa has proven to have a high potential in increasing farm resilience and mitigating climate change. However, no studies have yet examined the potential future climate suitability for shade trees in the region, which is important when deciding which shade trees to implement. READ MORE

6. 5. Estimating Future Forest Fire Risk in Gävleborg County Sweden in 2041-2070 Following RCP 8.5

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Vendela Cyrén; [2023]
   Keywords : Future forest fire risk; RCP 8.5; Gävleborg county; Climate change; Forest fire; Earth and Environmental Sciences;

   Abstract : Forest fires can act as an ecosystem service by providing habitat renewal, controlling pests, and reducing the risk of extreme fires, but can at the same time disturb an ecosystem negatively. Furthermore, forest fires release carbon dioxide into the atmosphere, damage property, and lead to health issues. READ MORE
