1. 16. Elastic hyperspectral lidar for detecting coherent backscatter from insects

   Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Lauro Müller; [2022]
   Nyckelord :Nanosopy; Thin film physics; Hyperspectral; Lidar; Super continuum; Insects; Coherent scattering; Infrared Spectroscopy; Hyperspectral Imaging; Biophotonics; Technology and Engineering;

   Sammanfattning : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.

3. 17. Constructing an optical tweezers instrumentation and evaluation of trapping stiffness using the power spectrum method

   Kandidat-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Haoxiang Yang; [2022]
   Nyckelord :;

   Sammanfattning : Optical tweezers can trap micron-sized objects such as cells, bacteria, and microspheres, and has become an important instrument for measuring forces associated with various physical and biological phenomena. In this thesis work, I constructed an optical tweezers instrument to trap 2µm diameter beads using a HeNe-laser operating with a wavelength of 632. LÄS MER

4. 18. En ny däggdjursart i Sveriges fauna : Etablering av stenmård (Martes foina) i nordöstra Skåne

   Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

   Författare :Elin Svensson; Karin Wetterberg; [2021]
   Nyckelord :Alien species; Establishment; Invasive alien species; Mitochondrial DNA; Pine marten; Stone marten; Etablering; Främmande art; Invasiv främmande art; Mitokondrie-DNA; Skogsmård; Stenmård;

   Sammanfattning : Skogsmård (Martes martes) har länge varit Sveriges enda mårdart men 2018 gjordes det första fyndet av en annan art, stenmård (Martes foina), i nordöstra Skåne. Efter att detta fynd uppmärksammats fick Invasiva Arter på Svenska Jägareförbundet in uppgifter om ytterligare tre fynd från området. LÄS MER

5. 19. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Esnart Emma Bwalya Chibwe; [2021]
   Nyckelord :sexual segregation; Daubenton’s bat; Myotis daubentonii; landscape analysis; habitat selection; foraging;

   Sammanfattning : Sexual segregation is a phenomenon present in many vertebrate taxa, including the bat order Chiroptera. Sexual segregation is a social and/or habitat separation based on sex and is driven by varying causes such as sexual dimorphism, resource and physiological limitations, predator avoidance and many other factors.

7. 20. Influence of garden structure and surrounding landscape on the presence of wildlife in Umeå

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Amanda Andersson; [2021]
   Nyckelord :urban; habitat selection; urban wildlife; garden; citizen science; Vulpes vulpes; Pica pica; wildlife gardening; wildlife friendly features; vegetation structure; greenspace;

   Sammanfattning : Around the world cities are growing. Expansion and densification often take place at the expense of urban greenspace, the most common habitat for urban wildlife. Even though gardens take up a significant amount of the city's green space, there are no general guidelines on how to manage garden to support local wildlife. LÄS MER
