  1. 1. The effect of the COVID-19 lockdown on the spatial ecology of moose in an area with high recreational activity

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

    Author : Maximilian Dörr; [2024]
    Keywords : Moose; Alces alces; habitat selection; tourism; human disturbance; activity; movement; speed; seasons; Covid-19; pandemic;

    Abstract : In diverse landscapes, the coexistence of wildlife habitat requirements and human land use often leads to conflicts, posing challenges for sustainable species management. Recreational activities, especially in sparsely populated areas, frequently disturb wildlife behavior, necessitating a comprehensive assessment of anthropogenic impacts on habitats. READ MORE

  3. 2. The use of regurgitated pellets from the great cormorant to detect the presence of the round goby

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Tim Dorup; [2023-08-07]
    Keywords : Invasive species; Regurgitated pellets; Great cormorant; Round goby; dPCR;

    Abstract : The round goby (Neogobius melanostomus) is an invasive alien species that poses one of the greatest threats to biodiversity and ecosystem services in Sweden today. The round goby originates from the Black Sea and Caspian Sea but has in recent decades rapidly spread with global shipping traffic to new areas in Europe and North America. READ MORE

  4. 3. Where can the Vendace (Coregonus albula) live during the least favourable period of the summer stratification in Lake Mälaren?

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Loa Andersson; [2023]
    Keywords : ;

    Abstract : Temporal stratification in lakes due to high air temperatures and dynamic wind conditions changes the environment for organisms in the depth gradient. For fish that have narrow requirements for temperature and oxygen conditions, stratification can lead to a significant reduction in habitat volume during the summer when surface temperatures are high.

  5. 4. Evaluating forest restoration effects on timing of avian dawn chorus in Ranomafana National Park, Madagascar

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

    Author : Marjolein Pijper; [2023]
    Keywords : acoustic monitoring; forest restoration; dawn chorus; avian singing; bird monitoring; automatic recognition;

    Abstract : Monitoring of forest restoration efforts is essential to ensure healthy, self-sustaining tropical rainforests. Passive acoustic monitoring is used to monitor vocal activity of birds, which play a key role in forest ecosystems as seed dispersers. READ MORE

  6. 5. Restoration effects on benthic macroinvertebrate diversity and community composition in a river

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Fredrik Laggar; [2023]
    Keywords : Benthic invertebrates; diversity; communtiy composition;

    Abstract : Physical restoration efforts are common methods to restore running waters containingdegraded ecosystems due to anthropogenic activities such as irrigation, ditching, dammingand flood prevention. The goal is usually to restore waters to a more natural state, creatingmore physically complex habitats supporting a larger number of species of both fish andinvertebrates, hence increasing biodiversity.
