  2. 1. Alloparental care and social dynamics in the fallow deer (Dama dama)

    Author : Kenneth Ekvall; Rory Putman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

    Abstract : In mammals, a sex difference exists in natal dispersal with females remaining in the natal area and males generally leaving the area of birth. Female groups are regarded as the basic social unit of many mammalian species, and in species with overlapping generations groups may develop a matrilineal structure. READ MORE

  4. 2. Ecology, sexual selection and variable mating tactics in fallow deer (Dama dama)

    Author : Cheryl Jones Fur; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Abstract : This thesis investigates ecological and evolutionary mechanisms behind the variation in male mating behaviour in fallow deer (Dama dama) populations. Two Swedish populations of fallow deer were studied, a semi-wild enclosed population on the island of Öland in the Baltic Sea (Ottenby), and a deer farm located north of Uppsala (Bälinge). READ MORE

  5. 3. Mating behaviour and sexual selection in non-lekking fallow deer (Dama dama)

    Author : David Stenström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Fallow deer; mating behaviour; sexual selection; scent marking; plasticity of behaviour; antler asymmetry; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Abstract : This thesis examines both behavioural and morphological traits influencing male mating success in non-lekking fallow deer (Dama dama). The thesis contains results based on behavioural observations and experimental studies made on Öland and around Uppsala, Sweden. READ MORE

  6. 4. Ticking off the ungulate box : the role of different ungulate species in the transmission of tick-borne pathogens

    Author : Nannet Fabri; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ungulates play a central role in the life cycle of Ixodes ricinus, an important vector of tick-borne pathogens, and several ungulate species are increasingly common across Europe. I investigated the role of these different species in the spread of I. ricinus-borne pathogens. READ MORE

  7. 5. Food choice in fallow deer – experimental studies of selectivity

    Author : Ulrika Alm Bergvall; Olof Leimar; Frederick D. Provenza; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; behavioural syndrome; neighbour contrast defence; neighbour contrast susceptibility; simultaneous negative contrast; plant secondary compounds; tannins; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : In this thesis, I experimentally investigate feeding selectivity in fallow deer (Dama dama), with respect to plant secondary compounds, especially tannins, which can decrease the quality of foods. I found that fallow deer avoided foods with higher amounts of tannic acid and Quebracho tannin, even though the deer ate some high-tannin food. READ MORE
