  1. 21. Spatiotemporal competition patterns of Swedish roe deer and wild boar during the fawning season

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Staffan Melberg; [2012]
    Nyckelord :Sus scrofa; Capreolus capreolus; interspecific competition; predation; spatiotemporal;

    Sammanfattning : Abstract This study was performed on Bogesund research area, Sweden, in order to determine whether wild boar (Sus scrofa) predates on fawns of roe deer (Capreolus capreolus) and if the spatial and temporal patterns of roe deer are related to wild boar activity. A behav-ioural response is beneficial for many organisms when they are exposed to interspecific competition. LÄS MER

  3. 22. Analysis of the biological role of prion-related Shadoo protein on early mouse embryogenesis

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

    Författare :Kadambari Chachondia; [2012]
    Nyckelord :Prion-family; Shadoo; Transgenesis; Mouse; Embryogenesis;

    Sammanfattning : The prion family comprises of Prion, Shadoo and Doppel proteins, encoded by Prnp, Sprn and Prnd, respectively.Expression pattern of these genes in early mouse embryogenesis was investigated using RT-PCR experiments on FVB/N mice embryosand by in situ hybridization (HIS) at 3 early developmental stages.

  4. 23. The effect of non-host plant volatiles on the reproductive behaviour of the Egyptian cotton leafworm, Spodoptera littoralis

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Altaf Hussain; [2012]
    Nyckelord :Adhatoda vasica; electrophysiology; Justicia adhatoda; Lepidoptera; Noctuidae; non-host plants; reproductive behaviour; semiochemical diversity; socioeconomics; Spodoptera littoralis; spruce;

    Sammanfattning : Spodoptera littoralis is a major pest of cotton in Egypt, causing serious economic losses. Egyptian farmers highly appreciate biological control of the pest as synthetic pesticides are very unsustainable. Phytophagous insects rely on plant volatiles to locate oviposition, feeding and, mating sites. We tested newly emerged S. LÄS MER

  5. 24. Hur påverkar inavel fruktsamheten hos häst?

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

    Författare :Hanna Selinus; [2012]
    Nyckelord :häst; inavel; fertilitet; fruktsamhet; fölningsprocent;

    Sammanfattning : Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. LÄS MER

  7. 25. Studenters kunskap om fruktsamhet och deras önskan om barnafödande. : en väntrumsundersökning

    Kandidat-uppsats, Institutionen för folkhälso- och vårdvetenskap

    Författare :Julia Lindblom; Martin Färdig; [2011]
    Nyckelord :fertility; knowledge; family planning; university students; fruktsamhet; kunskap; familjeplanering; universitetsstudenter;

    Sammanfattning : Aim: The purpose of this study was to describe, analyze and compare university students’ desire to have children, when they wanted to have their first and last child and their knowledge about fecundity in relation to the background factors: age, gender and educational level. This study will also investigate differences regarding university students’ desire to have children along with when they wanted to have their first and last child and their knowledge of declining fecundity at increasing age.
