  1. 21. Den asiatiska elefanten (Elephas maximus) i turismen : vilka blir konsekvenserna av utnyttjandet av asiatiska elefanter inom turismen?

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Lotta Svensson; [2017]
    Keywords : asiatisk elefant; turism; fångenskap; beteende; välfärd;

    Abstract : The Asian elephant (Elephas maximus) has played an important role in the cultural, economic and social life of Asia for millennia, and today elephant trekking and similar activities are a central image of the tourism marketing campaign. Though in most countries it has been illegal for years, elephants are harvested from the wild to be used for this type of work. READ MORE

  3. 22. A Study of Gradient-Based Algorithms

    University essay from Lunds universitet/Matematisk statistik

    Author : Rasmus Hallén; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : Gradient-based algorithms are popular when solving unconstrained optimization problems. By exploiting knowledge of the gradient of the objective function to optimize, each iteration of a gradient-based algorithm aims at approaching the minimizer of said function. READ MORE

  4. 23. Comparison of three different indirect methods to evaluate ungulate population densities

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Sabine Pfeffer; [2016]
    Keywords : wildlife ecology; density estimates; camera trapping - random encounter model; dung pellet group counts;

    Abstract : Reliable species population estimates are important for population conservation and management. Information about population sizes is needed to introduce certain preservation and regulation approaches. Several different methods, both performed in the field and analytical, can be used to estimate species densities. READ MORE

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Mathias Jönsson; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : This study sought to investigate the effect of microplastics on Mytilus edulis’s ability to filtrate water. The mussels were sampled at Hanö bay located in the Baltic Sea, and were transported to a controlled environment. READ MORE

  6. 25. Tidal Streams as a Probe of the Milky Way Assembly History

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Espen Kirkesæther Brun; [2016]
    Keywords : Astrophysics; Astronomy; Dynamics; Galactic; Tidal Streams; Stellar Streams; Dark Matter; Subhalos; Physics and Astronomy;

    Abstract : The current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way.
