  1. 1. Rising Temperatures and the Damselfly Shrinkage

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ernie Hacko Haglund; [2023]
    Nyckelord :Damselfly; Body; Size; Body Size; Temperature; Reproduction; Eggs; Egg; Egg Count; Flicksländor; Kropp; Storlek; Kroppsstorlek; Temperatur; Reproduktion; Ägg; Äggräkning; Antal Ägg;

    Sammanfattning : Body size governs how temperature affects an organism. As temperature vary on different geographical scales, it mediates activity based on size. LÄS MER

  3. 2. Investigating the temperature mediated effects of antidepressant pharmaceutical on foraging behavior and activity in aquatic invertebrates

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Johanna Björkman; [2023]
    Nyckelord :;

    Sammanfattning : Contamination by pharmaceuticals in aquatic environments is an increasing problem globally. Wide range of pharmaceuticals of different treatments classes are commonly detected in water and the tissues of organisms and there is a growing concern about how these substances might affect the aquatic ecosystems.

  4. 3. Challenges in a changing climate : The effect of temperature variation on growth and competition in damselflies

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Kim Lea Holzmann; [2022]
    Nyckelord :ecology; climate change; thermal variation; competition; cannibalism; damselfly;

    Sammanfattning : Climate change is affecting biodiversity on multiple levels all over the world. Concomitant with a higher mean temperature, an increased amplitude of temperature variation is predicted. LÄS MER

  5. 4. 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.

  7. 5. Wing Shape Variation In A Damselfly: Effects Of Range Margins And Latitude

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Desirée Kristensson; [2021]
    Nyckelord :damselfly; evolution; distribution; sexual selection; range margins; Lestes sponsa; geometric morphometric;

    Sammanfattning : An optimal wing shape is necessary for the survival of winged insects since it enables different survival strategies and is expected to vary between environments due to different selection pressures. However, few studies have explored wing shape variation across the whole range of a species. LÄS MER
