  2. 16. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Author : Cecilia Berg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

  4. 17. Impact of infertility and assisted reproductive technology on cancer risk

    Author : Frida E Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Ovarian stimulation drugs, in particular those used in assisted reproductive technology (ART) treatments for infertility, have been suspected to influence cancer risk. In addition, infertility per se may be a risk factor for some cancer types. READ MORE

  5. 18. How reproductive is a reproduction? : Digital transmission of text-based documents

  6. 19. Factors Affecting the Distribution of Rocky-Shore Macroalgae on the Swedish Coast : Morphological, Physiological, Reproductive and Genetic Aspects

    Author : Gustav Johansson; John Raven; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The aim of this thesis was to examine factors affecting the distribution of macroalgal species both vertically (depth zonation) and geographically along the Baltic Sea salinity gradient. Interactions between the physical environment and basic biological traits of the algae are emphasised. READ MORE

  7. 20. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations

    Author : Mårten B. Hjernquist; Lars Gustafsson; Marcel Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary ecology; competition; sex allocation; paternity; EPP; inadvertent social information; migration; breeding density; territory quality; territory availability; great tit; blue tit; Ficedula albicollis; Biology; Biologi; Animal Ecology; zooekologi;

    Abstract : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. READ MORE
