    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Linnea Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : Both vertebrates and invertebrates use an innate system to recognise and fight pathogens such as bacteria. In this study, I focus on the methods the freshwater crayfish Pacifastacus leniusculus possess to inhibit the Gram-negative bacteria via LPS-recognition. LÄS MER

  3. 2. Hemocytes and neural injury in freshwater crayfish : Does the melanization reaction matter?

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Amanda Gustafsson; [2022]
    Nyckelord :Melanization; neural injury; freshwater crayfish; Melanisering; nervskada; sötvattenskräfta;

    Sammanfattning : Neurogenesis primarily occurs during embryonic development in decapod crustaceans, ending when the embryonic precursor cells die. However, areas in the central olfactory pathway are exceptions to this. Here, neurons are produced throughout the animal’s life from precursor cells in the neurogenic niche. LÄS MER

  4. 3. Antropogena effekter på sötvattenlevande tiofotade kräftdjur : en litteraturstudie

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Viktoria Lidell; [2021]
    Nyckelord :Decapoda; tiofotade kräftdjur; sötvatten; antropogena effekter;

    Sammanfattning : The world is facing many anthropogenic threats against biodiversity and ecosystems. For an ecosystem to work, all components in it, for example different species of animals and plants, temperature, and precipitation, are vital. Freshwater Decapods are an order of crustaceans referred to as key species in freshwater ecosystems. LÄS MER

  5. 4. How can the Freshwater Pearl Mussel's (Margaritifera margaritifera) Situation Become Better in Lekhyttan

    Kandidat-uppsats, Fakulteten för samhälls- och livsvetenskaper

    Författare :Andrew Molin-Wilkinson; [2007]
    Nyckelord :Freshwater Pearl Mussel; Lekhyttan;

    Sammanfattning : Abstract This study takes up a local issue in the village of Lekhyttan, where Johan Molin is concerned about the freshwater pearl mussels (Margaritifera margaritifera) situation. He is a landowner and wonders what the situation is for the mussels and what he himself possibly can do, to hopefully improve their situation. LÄS MER
