1. 1. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Carl-Johan Dekker; [2023-08-07]
   Keywords : Invasive alien species; management; nature conservation; biodiversity;

   Abstract : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. READ MORE

3. 2. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

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

   Author : Elijah Ourth; [2023]
   Keywords : Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

   Abstract : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

   Abstract : Metoderna att odla jordbruksmark är många. Dessa odlingssystem påverkar markstrukturen och markhälsan på olika vis. Markhälsa är ett begrepp som blir allt viktigare. Under 2023 kommer EU med nya markdirektiv som ska säkra långsiktig odling och hjälpa till att nå klimatmålen. READ MORE

5. 4. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods

   University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Author : Markus Hellberg Mediaa; [2023]
   Keywords : Discontinuous Galerkin; Korteweg-de Vries; Conservation Laws; Partial Differential Equations; Numerical methods; Higher order spatial derivative; Heat Equation; Burgers’ Equation; Collocation; Lobatto Gauss Legendre; Stiffness; Nodal Approximation; Finite Volume; Finite Element;

   Abstract : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. READ MORE

6. 5. A recipe for fish and SNPs : Filling the blanks for conservation genomics of Swedish wels catfish (Silurus glanis) populations

   University essay from Uppsala universitet/Institutionen för ekologi och genetik; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Lars Littmann; [2022]
   Keywords : Catfish; Silurus glanis; Genomics; Genetics; Conservation; Mitochondrial; Whole-genome; NGS; Sweden;

   Abstract : Swedish populations of Wels catfish (Silurus glanis) experienced severe declines during the 19th and 20th centuries. The main causes for the decline were loss of suitable spawning habitat and fragmentation of populations. Currently, three native and two reintroduced populations remain in Sweden. READ MORE
