  1. 1. Neophobia and parental care in collared flycatchers (Ficedula albicollis)

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Maja Svedberg; [2023]
    Nyckelord :Neophobia; collared flycatcher; ficedula albicollis; parental care;

    Sammanfattning : Parental care can be important especially in passerine birds and can depend on environment, food availability and behaviour. A behaviour that can affect the food supply for the offspring is neophobia, the fear of novel objects. The more fear the bird exhibits the less it visits the nest with food. LÄS MER

  3. 2. Tawny owl ( Strix aluco ) and its variation in diet between years

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Casper Ekberg; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The tawny owl resides in temperate forests in Europe and mainly hunts rodents but can also hunt other animals like birds,invertebrates and bats. In this study I examined how the diet of tawny owls varies during the span of 2018-2020, I also compared the diet found from nest boxes with footage obtained from cameras inside the nestboxes.

  4. 3. The effect of nest box temperature on the breeding success of Pied Flycatchers (Ficedula hypoleuca) in northern Sweden

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

    Författare :Jorina Boer; [2018]
    Nyckelord :pied flycatcher; Ficedula hypoleuca; temperature; breeding success; microclimate; nest box;

    Sammanfattning : Benefits in terms of breeding success might arise from selecting nest sites with warmer thermal conditions. These energetic gains can subsequently be invested in increased breeding success by both parents and their nestlings. LÄS MER

  5. 4. Fixering av suggor under diperioden - hur påverkas djurvälfärd och smågrisdödlighet? Finns det några alternativa system?

    Kandidat-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Micaela Johansson; [2015]
    Nyckelord :inhysning; grisningsboxar; grisning; suggor; smågrisar; smågrisdödlighet; smågrisöverlevnad; modersbeteende; välfärd;

    Sammanfattning : Smågrisdödligheten är ett stort problem i grisproduktionen då den bidrar till en försämrad djurvälfärd. Många av de smågrisar som dör innan avvänjning kläms ihjäl av suggan. För att förhindra detta är det vanligt i många EU-länder att suggan fixeras under diperioden och i vissa fall även innan grisning. LÄS MER

  7. 5. Maternal behaviour in the laboratory mice C57BL/6J housed in a furnished environment : a pilot study

    L3-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Elin Weber; [2005]
    Nyckelord :mice; maternal behaviour; furnished environment;

    Sammanfattning : Maternal behaviour covers a wide range of behaviours and is one important factor that can increase survival. Behaviours such as nest building, nursing, licking, lifting or moving pups, retrieving, and protection of the young are often included when measuring maternal behaviour. LÄS MER
